If you have demonstrated that there is no feasible means to utilize employee protection on the "Hierarchy of Fall Protection" other than fall arrest, meaning there is no way to bring the work to the ground or to use a fall restraint, then you have accepted that at some point, your employee will fall.
Even though this is not specifically required by OSHA, wouldn't it make sense to have a prompt rescue capability for times when an employee is injured or becomes suddenly ill while working at height?This could be an employee who is protected by passive restraint but not PFAS. For instance, if an employee needs to climb a vertical fixed ladder to access a platform with perimeter guardrails 20 feet above the next lower level and is incapacitated due to injury or illness, how will you get that employee to the ground for treatment and transport? Most likely it will require a technical rope rescue effort or some other means of getting them from height and safely to the ground.
Additionally, there are products that will delay the onset of suspension trauma should a worker fall and remain suspended in their PFAS. An example is the FreeTech™ Harness available from Roco which significantly improves survivability post fall arrest. This unique harness buys time for the suspended worker while awaiting rescue.
Assisted, non-technical rescue can be accomplished using ladders, man lifts, or many other primitive but effective means. However, there comes a point where the situation will require some degree of technical rescue capability. If you have done an honest and knowledgeable assessment of the rescue needs for your facility for all the known or potential areas where you may have employees working at height, you very likely will have found the need for a technical rescue requirement.
If you are lucky, and your facility is located in a municipality that has emergency responders with a rope rescue capability that is willing and able to respond to your location, then you still must ensure that they can perform what needs to be done.
A really good way to do this is to have them come to your facility for the purposes of preplanning and hopefully demonstrating their abilities. Simply posting "911" as the plan, and calling it good, is not even close.Some facilities have in-house teams that are equipped and trained to perform technical rescue. These in-house teams are generally the fastest to respond and it usually eliminates the problem of relying on a municipal rescue team that may be called out on a separate emergency.
For companies that do not have a municipal agency that can and will respond or does not have the technical ability to perform the types of rescues that may be required, there is always the option of training host employees to perform these types of rescue.The first option is a single day of training using pre-engineered rescue systems or what we like to call "plug and play" systems. The second option is a two-day "build as you go" class that provides solutions in rescue environments that the pre-engineered systems are unable to cover.
Roco's one-day Pre-Engineered Rescue Systems training relies on manufactured rescue systems that require no knot tying, or the need to create mechanical advantages, or to load friction control devices. These systems are so straight forward that most students will be able to operate them safely and proficiently even if they haven't performed refresher training for several months. With these systems, you literally take the system out of a bag, hang it up to a suitable anchor, and you are ready to rescue.
Roco teaches a variety of techniques that are suitable for a conscious, uninjured suspended victim and also for an unconscious or injured victim who would need to be connected to the rescue system remotely by the use of a telescopic "gotcha pole." As straightforward and easy as this system is to become proficient with, it does have its limitations. For example, in order for this type of system to be employed, the rescuer(s) must be able to safely get into a position above or slightly offset, and within about 10 feet from the victim. If that is not possible, then it is time to prepare for a technical suspended worker rescue.Roco's two-day Suspended Worker Rescue class teaches a limited variety of knots, including tied full-body harnesses, mechanical advantage systems, anchoring, friction control, lowering, rappelling, hauling, and line transfer systems. These skills are not that hard to master, but they are perishable and require sufficient practice at regular intervals in order to maintain proficiency. This type of "build as you go" capability allows the rescue team to create a system that will work for just about any situation and structural configuration except for the most extreme settings.
So, if your facility seems to be behind the curve regarding the rescue of workers from height, you may need to discuss training options - either for the worker that has fallen and remains suspended from their PFAS, or for the one who is injured or ill at height with no way to get down.
Remember, a worker cannot hang suspended for any length of time without the danger of suspension trauma, which can be deadly.If we can assist you in assessing your fall protection rescue needs, please contact Pat Furr at firstname.lastname@example.org, or call our office at 800-647-7626.
