Confined Space Types - Are All Your Bases Covered?

Friday, November 30, 2018

Refineries, plants and manufacturing facilities have a wide range of permit-required confined spaces – some having only a few, while others may have hundreds. Some of these spaces may be relatively open and straightforward while others are congested and complex, or at height. With this in mind, are all your bases covered? Can your rescue team (or service) safely and effectively perform a rescue from these varying types of spaces? Or, are you left exposed? And, how can you be sure?

Rescue Practice & Preplanning

With a large number of permit spaces on site, it would be impossible for a rescue team to practice in each and every one. Plus, in most cases, the spaces are operating, functioning units within the plant. Because of this, section (k) of 1910.146 allows practice from “representative” spaces. This is where the Roco Confined Space Types Chart can make the process easier.

Using OSHA guidelines for determining representative spaces, the Roco Types Chart is designed to assist employers and rescue teams plan for various types of permit spaces.
The chart allows you to categorize permit spaces into six (6) confined space types, which can then be used to prepare rescue plans, determine rescue requirements, conduct practice drills or evaluate a prospective rescue service.

First of all, it's important to note that employers are required by 1910.146 and 1926 Subpart AA to allow rescue teams the opportunity to practice and plan for the various types of confined spaces they may be required to respond. This is critical for the success of the rescue, particularly timeliness, as well as for the safety of the rescuers.

Classifying and Typing Your Spaces
So, get out your clipboard, tape measure, some sketch paper, and a flashlight (if safe to do so) in order to view as much of the interior of the space as you can. And, if you absolutely need to enter for typing and/or rescue preplanning purposes, be sure to do so using full permitting procedures. Gaining access to architectural or engineering drawings may also be helpful in determining the internal configuration when actual entry is not feasible. Armed with this information, it is time to “type” the spaces in your response area using the Roco Confined Space Types Chart.

Over the decades, we’ve seen just about every type of confined space configuration out there. And, while there may be hundreds of permit spaces on site, most of them will fit into one of these six types and require the same (or similar) rescue plan. Of course, there are always unique situations in addition to physical characteristics, such as space-specific hazards or specialized PPE requirements, but this chart can be a valuable tool in the planning and preparation for confined space rescue operations.

We’ve also learned that it is imperative to understand the physical limitations of space access and internal configuration as well as how this affects equipment and technique choices for the rescue team. Referring to the Roco Types Chart and practicing simulated rescues from the relevant types of spaces will help identify these limitations in a controlled setting instead of during the heat of an emergency.

We can all agree that during an emergency is NOT the time to learn that your backboard or litter will not fit through the portal once the patient is packaged.
Six General Types
On the Roco Types Chart, you will note that there are six (6) general types identified, which are based on portal opening size and position of portal. Types 1 and 2 are “side” entries; Types 3 and 4 are “top” entries; and Types 5 and 6 are “bottom” entries. There are two types of each based on portal size, which is significant for rescue purposes. Openings greater than 24-inches will allow packaged patients on rigid litters or rescuers using SCBA to negotiate the opening; whereas, openings 24-inches or less will not.

Portals less than 24-inches will require a higher level of expertise and different packaging and patient movement techniques.
Once the various types have been determined, pay particular attention to spaces identified as Types 1, 3, or 5. Again, these spaces have the most restrictive portals (24-inches or less) and are considered “worst case” regarding entry and escape in terms of portal size. This is very important because it will greatly influence the patient packaging equipment and rescuer PPE that can be used in the space.

Accessibility and Internal Configuration
In addition to the “type” of the space based on portal size and location, another key consideration is accessibility or “elevation” of the portal. While the rescue service may practice rescues from Top, Side and Bottom portals – being at ground level is very different from a portal that’s at 100-ft. Here’s where high angle or elevated rescue techniques are normally required for getting the patient lowered safely to ground level.

Lastly, the internal configuration of a space must be carefully considered for rescue purposes. This will be discussed more in the following section on Appendix F.

Remember, rescue practice from a representative space needs to be a “true” representation of the kind of rescue that may be required in an emergency.
1910.146 Appendix F – Representative Spaces
In Appendix F, OSHA offers guidelines for determining Representative Spaces for Rescue Practice. OSHA adds that “teams may practice in representative spaces that are ‘worst case’ or most restrictive with respect to internal configuration, elevation, and portal size.” These characteristics, according to OSHA, should be considered when deciding whether a space is truly representative of an actual permit space.

(1) Internal Configuration 
What’s inside the space? If the interior is congested with utilities or other structural components that may hinder movement or the ability to efficiently package a patient, it must be addressed in training. For example, will the use of entrant rescuer retrieval lines be feasible? After one or two 90-degree turns around corners or around structural members, the ability to provide external retrieval of the entrant rescuer is probably forfeited. For vertical rescue, if there are offset platforms or passageways, there may be a need for directional pulleys or intermediate haul systems that are operated inside the space.

What about rescues while on emergency breathing air? If the internal configuration is so congested that the time required to complete patient packaging exceeds the duration of a backpack SCBA, then the team should consider using SAR. Will the internal configuration hinder or prevent visual monitoring and communications with the entrant rescuers? If so, it may be advisable to use an additional authorized rescuer as an “internal hole watch” to provide a communication link between the rescuers and personnel outside the space.

What if the internal configuration is such that complete patient packaging is not possible inside the space? This may dictate a “load-and-go” type rescue that provides minimal patient packaging while providing as much stabilization as feasible through the use of extrication-type short spine boards as an example.

(2) Elevation
If the portal is 4 feet or greater above grade, the rescue team must be capable of providing an effective and safe high angle lower of the victim; and, if needed, an attendant rescuer. This may require additional training and equipment. For these situations, it is important to identify high-point anchors that may be suitable for use, or plan for portable high-point anchors, such as a “man lift” or some other device.

(3) Portal Size
Here again, the magic number is 24 inches or less for round portals or in the smallest dimension for non-round portals. It is a common mistake for a rescue team to “test drive” their 22-to-23-inch wide litter or backboard on a 24-inch portal without a victim loaded and discover that it barely fits. However, the problem arises when a victim is loaded onto the litter. The only way the litter or backboard will fit is at the “equator” of the round portal. This will most likely not leave enough room between the rigid litter or backboard and the victim’s chest, except for our more petite victims.

For rescuers, it is already difficult to negotiate a portal while wearing a backpack SCBA. For portals of 24 inches or less, it’s nearly impossible. If the backpack SCBA will not fit, it is time to consider an airline respirator and emergency escape harness/bottle instead. Warning: Do NOT under any circumstances remove your backpack SCBA in order gain access to a confined space through a restricted portal or passageway. It is just too easy for a mask to become displaced.

(4) Space Access – Horizontal vs. Vertical
Most rescuers regard horizontal retrievals as easier than vertical. However, this is not always the case. If there are floor projections, pipe work or other utilities, even just a grated floor surface, it may create an incredible amount of friction or an absolute impediment to the horizontal movement of an inert victim. In this case, the entrant rescuers may have to rely on old-fashioned arm and leg strength to maneuver the victim.

Putting the Roco Types Chart into Practice
The Roco CS Types Chart can assist by first providing a way to classify and type your different kinds of spaces. This information can then be used to design training/practice drills as well as annual performance evaluations to make sure your rescue service is capable of rescue from the varying representative spaces onsite. Of course, this applies whether you use an in-house rescue team, a contracted rescue service, or a local off-site response team. Otherwise, how do you know if you truly have your bases covered? Don’t take that chance. If an incident occurs and the rescue personnel you are depending on are not capable of safely performing a rescue, your company could be culpable.

In section (k), OSHA requires employers to evaluate the prospective rescue service to determine proficiency in terms of rescue-related tasks and proper equipment.

Rescue Toolbox: Petzl ASAP LOCK

Wednesday, October 31, 2018

Experienced rescuers know there are several ways to belay, or provide a safety line for a live load. Traditional belays include Tandem Prusiks, aperture devices, Munter Hitch, modern devices such as the ID or the MPD, and several others. What all of these devices have in common is the belay system is anchored with the line running through it as the load moves away from the anchors, or the line is pulled through the belay to take in slack as the load moves toward the anchors. These types of belay systems must be tended by a dedicated operator.

But certain professions and even alpinists and sport climbers have been using a different means of providing a belay for many years. This type of belay has been called a self-belay, or a traveling belay and it works by having the belay device attached to a fixed safety line, and the device travels along with the load as it ascends or descends. Window washers and rope access technicians have been relying on this type of belay for many years. Even soloist rock climbers or mountaineers have been using variations of self-belay or for alpinists fixed lines to negotiate difficult pitches in lieu of a roped party climb. 

Up until recently, these traveling belays required the individual on rope to pull the device along both on ascent and decent.
In fact, many times, devices that were not intended to be used as a belay device were and are still being used for this purpose. I’ve seen window washers using handled ascenders as their belay device and try as I might to explain to them that it would have a high potential to fail upon a shock load, they said it was the best they could come up with. The Petzl Shunt was a bit of improvement over handled ascenders, but it still needed to be “towed” up and down the line and the operator needed to remember to let go of the tow string should the mainline fail otherwise the device would not lock onto the line. Most all cam type devices will fail to lock on the rope if the body of the device is held when it is called to arrest a fall. But in the recent past a new “rolling” fall arrestor became available that overcomes many of the limitations of traditional belay devices. It is called the Petzl ASAP.

The ASAP comes in two versions, the original International version and the newer ASAP Lock (pictured here). The primary difference between the two versions is the Lock has a means to lock onto the rope when you get to your intended position, which prevents a large loop of rope building between the top anchor and the device. This feature is critical for individuals that stop to perform a function at height where the potential for wind to blow rope into a growing loop between the device and the top anchor which would create an unacceptable potential freefall distance. Both versions are compatible with 10-13 mm kernmantle rope, but to meet ANSI Z359.15 certification, they must be used with the Petzl RAY 12 mm rope, and specified connectors and energy absorbers. 

One advantage of having a rolling fall arrestor is it reduces the manning requirements as there no longer needs to be an individual operating the belay.
Another advantage is there is no guesswork as to the amount of slack in the belay lane as is possible when the load is out of sight of the belay operator. This is particularly common on longer drops as the weight of the safety line can fool some less experienced operators into believing that is the weight of the load. 

But there are also potential disadvantages to an automatic rolling fall arrestor. If you do not plan ahead and there is a mainline failure and the load is arrested by the ASAP, it isn’t going anywhere. It will be stuck right where it arrests on the safety line – that is, unless you did think ahead and anchor the safety line into a dynamic anchor. We like to use the Petzl ID (pictured here) or the CMC MPD for this purpose. This allows for an immediate emergency lower on the safety line or even a haul by building the dynamic anchor into a Z-Rig.

We have found the ASAP in either version to be a great device on an administrative safety line during tower rescue training, as it closely replicates conditions as they would most likely be in a real world small team, or one-on-one tower rescue, while providing the required level of safety that is relatively transparent to all involved. 

So, come to one of our tower classes to see the ASAP in use, and it may just turn out to be another tool for your rescue toolbox. Here is more information on Roco’s 30-hour Tower Work & Rescue training. For further assistance, please call our office at 800-647-7626. Also, here’s a video on these devices from Petzl.

Inspection Process for Roco Training Ropes

Tuesday, August 28, 2018

Question: We recently had a student ask how our training rope is monitored for wear and tear because of its extensive use...

Answer: Good question, and it’s a big job for us, no doubt. We’ve used and inspected a lot of rope in the past 35+ years, but this aspect of life safety can never be overlooked or taken lightly. As always, we urge everyone to carefully follow the care, use and inspection guidelines provided by their rope manufacturer. For added safety and as standard practice, we also use secondary back-up ropes and hardware in all field activities. 

Because we train thousands of students per year, we must accept the fact that there are numerous opportunities for our ropes to be exposed to wear such as being stepped on or exposed to dirt and gravel. It is for these reasons that we perform rigorous inspection of the ropes before and after use. Plus, we also conduct an annual competent person equipment inspection as recommended by NFPA.

As added safety, we also expect our students to do their part in monitoring the equipment during a class, and that’s why we’re glad you brought this up.
We teach and enforce rope care and inspection of all equipment, including ropes, in all of our classes. Inspections are accomplished at multiple times during any given class including during inventory. Additionally, all equipment is inspected by a Roco employee at the conclusion of each class. If there are any signs of damage or degradation that would render the rope unserviceable according to the manufacturer’s instructions for use, that rope will be taken out of service.

Of course, we’ve seen some rope damaged over the years, which is to be expected with the use our rope receives. However, to my knowledge, we’ve never had a rope failure. We’ve seen cut sheaths and sheath slippage, evidence of broken core fibers, and other damage that failed the rope inspection. But, not once, have we had a rope fail while it was being used to support a life load. The construction and the minimum breaking strength requirements of life safety rope provide a very substantial margin of safety. And, there again, we also have the redundancy of a back-up system in place.

All manufacturers of life safety rope are required by NFPA 1983 (2017 edition) to provide the following inspection criteria information in their instructions for use:

(1) Rope has not been visually damaged.
(2) Rope has not been exposed to heat, direct flame impingement, or abrasion.
(3) Rope has not been subjected to impact load.
(4) Rope has not been exposed to liquids, solids, gasses, mists, or vapors of any chemical or other material than can deteriorate rope.
(5) Rope passes inspection when inspected by a qualified person following the manufacturer’s inspection procedures both before and after each use.

The following inspection tips are provided by PMI Life Safety Rope:

HOW TO INSPECT YOUR ROPE

LOOK AT IT.... ALL OF IT!
Start at one end and look at every inch of the rope. Watch for signs that might indicate possible damage such as discoloration, chemical odors, abrasion, cuts or nicks in the outer sheath and visible differences in the diameter of the rope in one area in relation to the rest of the rope.

WRAP IT IN SMALL LOOPS AND LOOK!
Wrap the rope around your hand to form small loops at different random points along the ropes length. Look at these small loops as you make them, the consistency of the loop should be uniform throughout. If it’s not, you might have a problem with the rope’s core.

FEEL THE ROPE!
While you are looking at every inch of the rope, run it through your bare hands and feel it for changes that might indicate damage to the core. Changes may include any inconsistencies in rope diameter, soft or “mushy” spots, or extraordinarily stiff areas.

WRITE IT ALL DOWN!
Write the results of your inspection on the Rope Log included with your rope. Be sure to include anything you found in your inspection that might be or become a concern and document other important information about the rope such as an occurrence of uncontrolled or excessive loading, rope older than 10 years, contact with harmful chemicals, and history of use.

IF IN DOUBT, THROW IT OUT!
If you are not sure about the integrity of a rope........DON’T USE IT!
Consult the manufacturer if you need help.

So, thank you again for asking about the rope used continuously in our training programs. Even with our many years of experience, we do not take rope safety margins as a license to misuse our ropes. And that is why we are diligent in caring for and inspecting all of our equipment including the ropes.

Know When NOT to Enter a Confined Space!

Friday, August 17, 2018

There are countless injuries and deaths across the nation when workers are not taught to recognize the inherent dangers of permit spaces. They are not trained when "not to enter" for their own safety. Many of these tragedies could be averted if workers were taught to recognize the dangers and know when NOT to enter a confined space.

While this incident happened several years ago, it emphasizes the senseless loss of life due to a lack of proper atmospheric monitoring and confined space training. Generally, the focus for training is for those who will be entering spaces to do the work. However, we also must consider those who work around confined spaces – those who may be accidentally exposed to the dangers. Making these individuals aware of the possible hazards as well as to stay clear unless they are properly trained.

Note: This case summary from the New York State Department of Health goes on to say that the DPW had a confined space training program but stopped the training after the last trainer retired.

CASE SUMMARY - TWO (2) FATALITIES
A 48-year-old male worker (Victim I) employed by the Department of Public Works (DPW) and a 51-year-old male volunteer firefighter (FF Victim II) died after entering a sewer manhole located behind the firehouse. In fact, the Fire Chief was on scene because he had been called by the DPW general foreman to unlock the firehouse and move the firetruck so it would not be blocked by the DPW utility truck working at the manhole. Another firefighter also arrived to offer assistance, he later became FF Victim II.

The manhole was 18 feet deep with an opening 24-inches in diameter (see photo above). Worker Victim I started climbing down the metal rungs on the manhole wall wearing a Tyvek suit and work boots in an attempt to clear a sewer blockage. The DPW foreman, another firefighter and FF Victim II walked over to observe. They saw Victim I lying on the manhole floor motionless. They speculated that he had slipped and fallen off the rungs and injured himself. The Fire Chief immediately called for an ambulance.

Meanwhile, FF Victim II entered the manhole to rescue Victim I without wearing respiratory protection. The other firefighter saw that FF Victim II fell off the rungs backwards while he was half way down and informed the Fire Chief. The Fire Chief immediately called for a second ambulance and summoned the FD to respond. FD responders arrived within minutes.

The Assistant Fire Chief (AFC) then donned a self-contained breathing apparatus. He could not go through the manhole opening with the air cylinder on his back. The cylinder was tied to a rope that was held by the assisting firefighters at the ground level. The AFC entered the manhole with the cylinder suspended above his head. He did not wear a lifeline although there was a tripod retrieval system. He secured FF Victim II with a rope that was attached to the tripod.

FF Victim II was successfully lifted out of the manhole. The AFC exited the manhole before a second rescuer entered the manhole and extricated Victim I in the same manner. Both victims were transported to an emergency medical center where they were pronounced dead an hour later. The cause of death for both victims was asphyxia due to low oxygen and exposure to sewer gases.

Contributors to the Firefighter's Death:
• Firefighters were not trained in confined space rescue procedures.
• FD confined space rescue protocol was not followed.
• Standard operating procedures (SOPs) were not established for confined space rescue.

The DPW had developed a permit-required confined space program but stopped implementing it in 2004 when the last trained employee retired. They also had purchased a four-gas (oxygen, hydrogen sulfide, carbon monoxide and combustible gases) monitor and a retrieval tripod to be used during the training. It was reported that a permit-required confined space program was never developed because DPW policy “prohibited workers” from entering a manhole. However, the no-entry policy was not enforced. Numerous incidents of workers entering manholes were confirmed by employee interviews.

This incident could have been much worse. Training is the key, whether it’s just an awareness of the dangers in confined spaces or proper entry and rescue procedures. In this case, the victims had no C/S training even though they may have to respond to an incident, and the worker had not had on-going training through out his career. Periodic training to keep our people safe and aware of proper protocols is key to maintaining a safe work force.

Unfortunately, training is usually one of the first things to be cut when the budget gets tight; however, after an incident, it usually becomes the primary focus. Often the lack of training is determined to be a key element in the tragedy.
Investing in periodic training for the safety of your workforce includes spending the time and money to keep your trainers and training programs up to speed and in compliance. The old saying, “closing the barn doors after the horses escaped,” is no way to protect your people – a little investment in prevention goes along way in preventing these tragedies.

One last comment on my biggest pet peeve – proper, continuous air monitoring. This one step can reduce the potential of a confined space incident by about 50%! Don’t take unnecessary chances that can be deadly.

Dennis O'Connell has been a technical rescue consultant and professional instructor for Roco Rescue since 1989. He joined the company full-time in 2002 and is now the Director of Training and a Chief Instructor. Prior to joining Roco, he served on the NYPD Emergency Services Unit (ESU) for 17 years.

Rescue Toolbox: Portable Anchors

Thursday, August 09, 2018

PJs use a tripod to extract a patient from a confined space.Portable Anchors – Bipods, Tripods, Gin Poles, and Quads

As rope rescue technicians, we learn early to look for that perfect high-point anchor. You know the one. It’s easy to sling, positioned perfectly in line with the portal and the rescue system, and rated for the anticipated load. We all know that they can be elusive, to say the least.

In locating high-point anchors, we learn to first look straight up for an anchor strong enough and high enough to allow us to clear a vertical litter out of a space (requires about 9 feet). Then we look left and right. Are there beams or substantial anchors high enough and positioned to allow a high-point bridle for our lift? Or maybe there’s an anchor positioned were we may be able to “cowboy” a rope up and over a beam and adjust our end-of-line knot at the appropriate height; and then tie it back to another anchor (extended anchor technique).

But what about those times where we need a high-point anchor, and there is nothing, nada, zilch? No beams, trees, nothing! That’s when we bring our own high-point, also called a portable anchor. 

Portable anchors come in a variety of configurations, the most common being tripods. Even tripods are not all created the same. Some are rated only for equipment, others have different allowable working loads, and they come in a variety of heights. 

There is also the option for bipods, quadpods, monopods (gin poles) and some devices that can transform into all of these configurations. They can be centered over a portal for straight, vertical lifts (tripods/quadpods), straddle the plumb line (bipods), or provide a single high-point in an area with a small foot print (monopods). They can even be designed to cantilever out over an edge to provide a clear path for the ropes and ultimately the rescue package. Determining which one to use would be based on your team’s needs and your type of response area.

So, let’s talk about some of the portable anchors that we like to use, including their capabilities and limitations.

Tripods

The SKED-EVAC® Tripod is a simple tubular aluminum tripod with cast header and feet. It extends to a maximum height of 10 feet at the anchor connection points, which gives a good bit of clearance for vertical litters to clear the bottom edge. At full extension (10 feet), the tripod is proof loaded to 5,280 pounds. The SKED tripod is simple to set up, includes a chain to run through the feet to keep the load stresses off the cast header, includes three anchor points, and adjusts in height for situations where there isn’t enough headroom for full extension.

Eccentric Loading and Resultant Forces

Tripods as well as other portable anchors must be respected when it comes to the “direction of pull” on the rescue system and the relationship to the position of the load. Here are a few terms to be familiar with:

Axial loading: The object is loaded in line with the normal fixed axis point (the center of a tripod, equal force on all legs).
Eccentric loading: The load is no longer axial and is offset from the axis point. (The system puts side-load forces on the anchor, or the load is moved out from under the axis point.)
Resultant: This is the relationship between forces acting on an object. (It is the relationship between the load and the vectoring forces of the rescue system from the portable high-point; it is the bisection of this angle.)

The “rule of thumb” for tripods is the resultant forces must remain inside the footprint of the tripod. That is, if the rescue load is pulling straight down (plumb/axial), and the rescue system vectoring forces are angled outside of the footprint of the tripod, then where does the bisection of that angle fall?

Imagine drawing a circle that connects the legs of the tripod. As long as the load and the rescue system remain inside that circle, the resultant will be acceptable, and the tripod will remain axially loaded and not tip over.

There are some techniques to overcome this limitation such as a directional pulley located within the footprint of the tripod. Another technique, which we call the “Pass Through” method (see illustration at bottom), allows counter acting resultant forces to stabilize the tripod. If your haul line is angled too far outside the footprint of the tripod, or the load is moved outside the tripod footprint, the entire tripod is at risk of toppling over (eccentric loading), which could spell disaster.

So, to keep things simple, we often recommend that all lines are kept within the footprint or to add a low directional within the footprint. This provides a small margin for error when hauling or setting up a directional. Technically, you can set up the directional outside the footprint (or pull the haul line outside the footprint) as long as the resultant force is still inside. 

Just remember to envision all lines as though they were loaded before you load the system. We’ve seen plenty of low directionals that were set up perfectly; however, the anchor strap actually allowed them to fall outside the footprint once loaded. As we like to say, "keep it safe and simple!"(KISS) And to play it safe, keep all lines within the footprint.

Multi-Use Portable Anchors

Portable anchors have progressed way beyond the tried-and-true tripods. We are seeing some pretty versatile systems that can be configured as quadpods, bipods, even monopods. These modern systems provide capabilities that go beyond straight vertical lifts while straddling the hole or entry into the rescue subject’s location.

As with most devices that provide additional or alternate capabilities such as monopods and bipods, they are generally more complex and require additional training to fully understand the forces being applied. The ability to extend an anchor point out over the edge of a containment berm, or a cliff edge in a wilderness rescue, will greatly reduce friction on haul lines and reduce rope abrasion, providing clear movement of the rescue package coming up or going down over the edge. This is something that a tripod just cannot provide. But a better mastery of the effects and relationships of the forces being applied needs to be obtained. Understanding and identifying the resultant force is critical in these situations.

These new generation multi-purpose devices, such as the TerrAdaptor™ or the Arizona Vortex, are designed to be used as tripods, bipods, monopods; or in the case of the TerrAdaptor, as a quadpod. They are third party (UL) certified to NFPA 1983 in symmetric tripod and quad-pod configurations. In addition to the straight vertical capabilities, these devices also provide an “over-the-edge” capability. 

For tight areas such as on catwalks, the A-Frame configuration or bipod can provide that portable high-point where a tripod just can’t fit. For extremely tight quarters or when lightweight gear is needed, they can be rigged as a monopod or gin pole. This requires some advanced knowledge of rigging and tiebacks; but, rigged correctly, it provides high strength and a high-point in places no other system would fit. 

Sometimes the configuration of the structure or the height of your portable anchor does not allow enough overhead to clear the foot-end of a vertical litter. In instances like this, you may need a simple mechanical advantage assist that is attached low on the litter, or a modified Pick & Pivot technique where the lifting point on the litter is changed from the head to the feet once the litter reaches an edge to allow recovery.

Smaller, Lighter, Stronger

To meet the demands of the USAF Pararescuemen (PJs), Roco worked with Skedco to develop the Roco Tactical Mini-Tripod

Reaching about 5 feet at maximum extension with removable legs, it is small enough to carry in the team’s rucksacks, if needed. Its short height also makes it the strongest rescue tripod on the market. Additionally, the removable legs provide the ability to use it as a bipod or A-frame.

Utilizing some simple techniques, a vertical litter patient can be removed from a space with the Roco Mini-Tripod just as easily as with a full-size.

The lighter weight, compact size, and full functionality allow teams with limited manpower and resources to operate without limited capabilities.

Conclusion

It is important to know what your needs are regarding portable high-point anchors. Complete your rescue preplans. And, if they reveal the need to cantilever out over an edge, or that a bi- or monopod may be required, you may want to consider a multi-functional, portable high-point system that provides capabilities beyond a tripod. Whichever device you choose, always make sure you get the proper training. The unexpected loss of a high-point during training or a rescue could be disastrous. So, be safe, know your equipment and know how to use it.
