Are You Sure You Don't Need On-Air Rescue Practice?

Thursday, August 28, 2014

Reported by Dennis O’Connell, Director of Training

After more than 25 years in the rescue industry, I always cringe a bit when I hear rescue teams say they don’t practice “on-air” rescues because personnel at their facilities are not allowed to do planned work activities in IDLH or low O2 areas. But I always ask, what about the permit spaces that may have the “potential” for atmospheric hazards? What about those spaces that may unexpectedly become IDLH or low O2 – what then?  

"I have raised this flag many times before and according to NIOSH, a little less than half the deaths from atmospheric conditions occurred in spaces that originally tested as being acceptable for entry. Something happened unexpectedly, and something went very wrong."

Remember, OSHA states that a confined space simply has to have the “potential” for a hazardous atmosphere; not that it is actually present as one of the triggers to make a space a “permit required space” and require rescue capabilities.

So, for these unexpected instances, do you really have the appropriate rescue response in place? In our opinion, not training your team to respond to IDLH emergencies is like buying a gun for home protection, but not buying any bullets.

Also, 1910.146 section (k)(1)(i) makes reference to 1910.134 OSHA’s respiratory regulation. Here OSHA talks about respiratory protection being worn by entrants as the trigger for “standby” rescue personnel capable of immediate action. It is not necessarily based on the level of O2. It calls for “rescue standby” not rescue “available.” Immediate action is called for… not just a timely response

OSHA Note to Paragraph (k)(1)(i)…
What will be considered timely will vary according to the specific hazards involved in each entry. For example, §1910.134, Respiratory Protection, requires that employers provide a standby person or persons capable of immediate action to rescue employee(s) wearing respiratory protection while in work areas defined as IDLH atmospheres.

If that’s not a hint as to how seriously OSHA takes the possibility of an IDLH atmosphere arising in a permit space, I don’t know what would be.

So, if you don’t think you’ll ever need on-air rescue capabilities, take a look at this incident from a few years back. The way this confined space fatality occurred and the possibility of it happening is a real eye opener. It emphasizes the critical importance for considering all possible (or potential) hazards associated with confined space entry and rescue.

Folks what I’m trying to say here is, as rescuers, we need to be prepared for the worst case scenario as well as the unexpected! This is especially true when it comes to confined spaces. When I hear, "We don’t need on-air practice because we don't allow IDLH entries at our facility." Well, neither did these guys...


Fatal Activation of CO2 Fire Protection System in Confined Space

 


Sheffield Forgemasters was ordered to pay heavy fines and costs for safety failings that led to an employee dying of carbon dioxide poisoning after the cellar he was working in filled with the deadly gas. A worker was found unconscious at the South Yorkshire foundry after a confined underground area swiftly flooded with the fire-extinguishing mist. Four of his co-workers desperately tried to reach him but were themselves almost overcome by the fast-acting gas. The worker, who had three grown-up sons, was pronounced dead on arrival at the hospital after the incident at the firm’s plant on 30 May 2008.

The Health and Safety Executive (HSE) investigated and prosecuted the company for serious safety failings. On December 19th 2013 Sheffield Crown Court heard that on the morning of the incident, the worker had carried out part of the cable cutting task in an electrical drawpit and then went to carry out the rest of the job in the switchroom cellar, which was only accessible by lifting a manhole cover and dropping down a ladder. Once underground at the electrical drawpit, the worker used a petrol-driven saw to cut through redundant 33,000 volt cables. At some point, he moved from there to the nearby switchroom cellar with the saw.

Later that morning, colleagues heard the carbon dioxide (CO2) warning alarms sounding from the cellar. A supervisor and other workmates rushed to help, with several of them trying to get down the ladder from the manhole to rescue the worker from the cellar’s confines. However, all attempts were defeated as each worker struggled to breathe and remain conscious when exposed to the debilitating concentrated carbon dioxide. The victim had to be brought to the surface later using slings.

HSE found that use of the petrol-driven saw in the switchroom cellar had likely activated a smoke sensor and prompted the release of the carbon dioxide from the fire extinguishing system.

The court was told Sheffield Forgemasters had failed to provide any rescue equipment for either the cellar or the drawpit. Other issues identified included a lack of a risk assessment by the firm for the cable cutting task and failing to provide a safe system of work in either underground location. In addition, there was no secure way to isolate the carbon dioxide fire system while work was going on in the cellar.

After the hearing, a HSE Inspector said: “This was a very upsetting incident that resulted in the needless death of this employee. It could have been an even worse tragedy as it was pure chance that another four workers who entered the cellar in a desperate bid to save their colleague did not also perish.” 

“Exposure to between 10-15% of CO2 for more than a minute causes drowsiness and unconsciousness. Exposure to 17-30% is fatal in less than one minute. Carbon dioxide is poisonous even if there is an otherwise sufficient supply of oxygen. 

“The risks associated with confined spaces are well known in industry and there is an entire set of regulations dealing with controlling the risks associated with them. Multiple fatalities do occur when one person gets into difficulty in such a space and then the rescuers are similarly overcome.”

“Sheffield Forgemasters had given no thought to the risks associated with the task being undertaken, nor had they provided emergency rescue equipment. This case shows how important it is for companies to effectively risk assess work activities; looking at how the work will be carried out and in what circumstances.”

Roco QUICK DRILL #4 - Selecting the Proper Knot and Tying Correctly

Wednesday, August 13, 2014

Being able to tie a knot in the classroom with a rope short vs. selecting the proper knot and tying it correctly in the field during an emergency requires experience. With a little imagination, you can provide your team members numerous scenarios to practice in just a short period of time while they are still within a controlled environment. This practice will help them to gain more experience that should pay off in the long run if needed during a real life emergency.

1.  Identify the knots your team uses, and where they are used in various systems.

2.  Lay out a series of applications where team members would need to tie a knot. Decide in advance what knots are acceptable in these applications since many times more than one knot may get the job done.

3.  Once you have established the acceptable knots, lay out a gauntlet of knot tying stations.

4.  Each team member will go through each station... first, deciding which knot to use, and then tying it as it would be used in the application (examples: end knot in a lower line, vertical bridle knot, lashing a backboard, adjustable anchor, self-equalizing anchor, etc.)

The goal is to have team members choose an appropriate knot, tie it correctly, and apply it properly based on the rescue system presented. Two examples for knot stations are: (1) Backboard lashing - have the lashing complete except for the knot at the end; and (2) Mainline rigged except for the knot attaching it to the anchor.

Roco QUICK DRILL #3 - Knot Tying Challenge

Monday, June 09, 2014


A question that we often hear is, “How proficient should rescuers be with knot tying?” We recommend that rescuers be able to tie any of the knots used by their team without hesitation, or without even having to look at the knot as they are tying it.

As part of the skills requirement in our Roco certification courses, we require students to tie each knot (with safeties, as required) within 30 seconds. This gives us a good idea of the student’s proficiency in the basics of knot tying.

Here's a knot drill that we recommend: 

1.  Give each team member a length of rope and a piece of webbing. Note: Some knots will require an object to tie around.

2.  In a room capable of being darkened, call out the name of the knot to be tied and then turn off the lights. As each person finishes, have them shout “Completed.”

3.  Once all members have completed the knot, turn on the lights and check for accuracy.

Having the lights off during this drill forces rescuers to use their other senses in remembering how to tie the knots. It helps to reinforce their skills and is an excellent way to identify the individual knot(s) that may require more practice for increased proficiency. When the pressure is on – as in a real rescue – you need to be able to count on all your team members to tie the needed knot in a timely and accurate manner.

Q&A: Sked Stretcher - Is a Backboard Required?

Wednesday, April 02, 2014

READER QUESTION:
Can a patient be lowered in a vertical or horizontal Sked without being lashed to a backboard or without a backboard at all?

ROCO TECH PANEL RESPONSE:

The answer is YES! This is one of the advantages of choosing the Sked stretcher.


It can be used with most (if not all) backboards, with a short spine immobilizer, or with nothing at all.

There are two general considerations in deciding what device to use with the Sked or other flexible litters:

(1) Patient Condition - If spinal injuries or other injuries need the splinting effects or the protection of a backboard, then the victim should be lashed to a backboard. When a backboard is not in place, the Sked will help keep the body in line when tightened; however, the spine can continue to be manipulated up and down as patient is moved over objects or edges which can compromise the spine.

If you are just using the backboard to keep the Sked rigid or protect the patient while placing them over edges, then technically you would not need to lash them to the backboard.

When a confined space is too tight to use a backboard and possible spinal injuries are suspected, or additional protection for placing a patient over an edge is wanted, then a short spinal immobilizer such as the OSS can be used. If a spinal injury is not suspected, then no additional equipment needs to be used with the Sked. It is always good to keep in mind, however, that the thin plastic make-up of the Sked will allow the patient to feel every edge or bump you place or drag them over.


(2) Location
- What size portal do you need to get the patient and packaging through in order to perform the rescue? Many times in portals less than 18-inches, the individual pieces of equipment will fit into the space, but once put together they will not fit back out of the space. The Sked was designed for this specific circumstance. The thin plastic construction allows it to fit in places many other litters will not.

The Sked can also be used vertically with the bottom not curled and secured in cases where a hare-traction splint or other injury doesn’t allow securement at the bottom.

The Sked is a very user-friendly device that can be used in a multitude of configurations and for various applications. This is one of the reasons why it is such a popular rescue tool, especially for confined space rescue! Stay safe!
