NFPA 1006, 2021 Updates

Earlier this week, the 2021 update to NFPA 1006 Standard for Technical Rescue Personnel Professional Qualifications was released. I have been tracking the changes coming for quite some time and have been tweaking my curriculum accordingly. Here are some of my thoughts on some of the changes.

Rope Rescue Operations is a pre-requisite for…

If you remember, the 2017 update did away with the “General Requirements” chapter and moved most of those job performance requirements (JPRs) to the Rope Rescue Awareness and Operations chapters. Naturally, Rope Rescue Operations then became a pre-requisite for many of the other disciplines.

In the 2021 update, Rope Rescue Operations was removed as a pre-requisite for many of the major disciplines. It is still required for certain disciplines that require a lot of rope skills, such as Tower Rescue, Confined Space Rescue, and Swiftwater Rescue. However, it was removed from many others such as Structural Collapse Rescue Technician, which was surprising to me and something I do not totally agree with.

Ascending and descending rope is now technician level

The 2021 update has moved the skills of ascending and descending rope to the technician level. This also includes being able to self-rescue from a jammed or malfunctioning descent control device. I think this was a good move to make. Operations level personnel are still required to get on rope while being lowered and raised by their teammates, but most of the operations level skills now are boots-on-the-ground rigging skills. The technician level includes all of the more challenging on-rope skills and advanced rigging systems such as horizontal rope rescue systems.

Vehicle Rescue has been changed, AGAIN!

In the 2013 edition, vehicle rescue was still combined with machinery rescue. In 2017, vehicle and machinery rescue were split into two separate disciplines. Vehicle rescues involving passenger vehicles were considered operations level and rescues involving heavy vehicles were technician level.

In the 2021 update, the committee has separated vehicle rescue into two different disciplines. We now have Common Passenger Vehicle Rescue and Heavy Vehicle Rescue, each with their own set of awareness, operations, and technician level JPRs. The rough break down is that if the vehicle is resting on all four-wheels or as it is intended to be used, it is operations level. If the vehicle is any other position it is technician level.

I like the way the new standard breaks down vehicle rescue into two different disciplines. Unfortunately, some places still have not finished updating their curriculum to meet the 2017 revision, and this 2021 update will likely cause even more confusion at the local level.

There were obviously other changes made to the standard, but these were the three biggest updates that I noticed. Elder Technical Rescue Services, LLC will be using the updated standard in all our programs immediately. Contact us to discuss setting up training for your agency.

Pre-Planning Elevator Rescues, Part 2/2

Elevators are incredibly complex machinery systems, and they are also one of the more common causes of machinery rescue incidents in urban and suburban areas.  One strategy for improving your agency’s response to elevator rescue incidents is to get out and start pre-planning the elevators in your community.  In this post, we are going to finish up discussing some of the information that can be included in an elevator rescue pre-plan.

Type of Elevator System(s)

The two broad categories of elevators are hydraulic (buildings < 6 stories) and traction elevators (buildings > 6 stories).  Within each of these broad categories there are many variations.  It is important for first responders to understand the basic differences and hazards associated with each elevator type.  Knowing the elevator type may also help you locate the elevator machine room.  Which leads us into our next piece of information.

Location of the Elevator Machine Room(s)

Securing the power to the elevator is one of the most important steps to take when performing an elevator rescue.  Unfortunately, there are still many first responders skipping this step.  Pre-plan the location of the elevator machine rooms in your buildings, so that you can quickly and efficiently secure the power when called upon to perform a rescue in an emergency situation.  Keep in mind, some elevators are being built now as machine room less (MRL) systems.  These elevators may not have a traditional elevator machine room.

Location and Type of Elevator Keys

There are two types of keys first responders should be concerned about: the fire service key and hoistway door key.  The fire service key will allow first responders to recall the elevators to a designated landing (typically the lobby) using the Phase 1 recall.  Some departments will have possession of these keys, while others will have to rely on retrieving them from the facility at the time of the incident.  The other keys first responders should be familiar with are hoistway door keys.  Hoistway door keys allow first responders to open the door leading into the elevator from the floor.

Do you include any other information in your elevator rescue pre-plans?

Pre-Planning Elevator Rescues, Part 1/2

Elevators are incredibly complex machinery systems, and they are also one of the more common causes of machinery rescue incidents in urban and suburban areas.  One strategy for improving your agency’s response to elevator rescue incidents is to get out and start pre-planning the elevators in your community.  In our next two posts, we will talk about some of the different sections you may want to include in your elevator rescue pre-plan.

Elevator Maintenance Company

This is one of the most important pieces of information to pre-plan.  Ideally, removal of occupants from a stalled elevator should be performed by the elevator maintenance company.  Even when an emergency situation exists and first responders must perform the rescue, it is still important to ensure the elevator company has been called.  At the very least, the elevator company will need to make any necessary repairs and place the elevator back in service.

Location of the Elevator(s)

Facilities may have multiple elevators located in different parts of the building.  These different elevators may each serve different floors and/or may even be different types of elevators.  If a 911 caller says that they are experiencing a heart attack in elevator three, do you know where elevator three is in that building?

IMG_4431

The pictures above show elevators 1 – 3 in an office building.  The elevators, mainline disconnects, and car light switches are all labeled accordingly.  However, it is also important to realize that this building has three additional elevators labeled 4 – 6.  Those elevators are on the other end of the building and have their own elevator machine room.  Pre-planning the locations of these elevators can help save time when someone is trapped in the elevator and experiencing a medical emergency.

Next week we will discuss some additional pieces of information that should be included in an elevator rescue pre-plan.

Tips for the Vehicle Rescue Officer

Vehicle rescues are probably the most common type of technical rescue incident we encounter as first responders.  However, we still have to stay on top of our games.  In this blog post, we will discuss some tips and tricks that you can implement as an officer at your next extrication.

Performing a scene size-up is key.  The officer should do a 360 degree walk around the accident scene, if possible.  Identifying and mitigating scene hazards is obviously important, but for the purposes of this post we are going to focus on the rescue size-up.  The rescue size-up focuses on how we are going to safely and efficiently stabilize the vehicle, access, disentangle, and extricate the patient.  It is imperative that the officer mentally begins to develop multiple plans of attack for each of these tasks.

The officer must be willing to receive input from other first responders on-scene, but ultimately the incident will progress the smoothest if there is an officer with strong leadership skills that can make decisions on the tactics employed.  I have been at many vehicle rescue incidents where there seemed to be multiple individuals making decisions, and it always resulted in confusion, frustration, and ultimately a slowed rescue operation.

One of the most important individuals you must receive input from at a vehicle rescue incident is the EMS provider-in-charge.  A lot of times we think that there are only two modes of operation at a rescue scene – rescue and recovery.  However, the reality is that included in that “rescue” mode are several different variables.  Whether the patient is stable or unstable is one of them.  If the EMS provider on-scene tells you the patient is unstable, then it is time to pick up the pace and extricate as quickly as possible.  If they are stable, then you may have time to perform all the disentanglement techniques and create as much space as possible.  The only way you can make the best decisions for the patient is to have strong communications with EMS.

Prehospital Treatment of Crush Syndrome

You and your partner are dispatched as the first due responding ALS unit for an industrial rescue. The dispatch notes indicate that one worker is trapped after an accident, but no other workers are injured. You see that you have a heavy rescue, a rescue-engine and ladder company responding with a chief officer. Enroute, you and your partner start discussing how you will approach the extrication and the medical treatments that may be necessary.

The scenario described above falls into the category of low frequency, high impact. Simply stated, they don’t happen all that often, but when they do, they are time and resource intensive. You may only have an annual refresher on technical rescue and the medical treatment of these types of patients. Lastly, with the low frequency of these events, we are not able to refine our skills through repetition on the job. With any technical rescue, the first consideration should be, “Is the scene safe?” You will need to consider what other resources you may need on scene such as a second or third ALS unit for other victims and the rescuers.

Arriving on scene you are directed to a staging area that will allow suitable egress from the incident. You find the victim conscious, alert and oriented with a patent airway. There is a large concrete pipe laying across the patient’s right femur. His chief complaint is leg pain, and he denies any other injuries. You attach your cardiac monitor and see that other than a slightly elevated normal sinus rhythm heart rate, all other vital signs are within normal limits. You establish two large bore IVs and follow your protocol for pain control with analgesia. By now the rescue company has determined that the best way to extricate the victim will be by using air bags to lift the pipe. The patient’s right leg has been pinned by the concrete pipe for 45 minutes. The rescue company say that they are ready to lift and are waiting for you to give the go ahead. Coordinated extrication is key in the removal of any victim, but with crush syndrome it is paramount due to the type of injury.

Crush injuries differ from other types of blunt force trauma. After as little as thirty minutes, the damage to large muscle groups will have a profound effect on your patient. When cells are crushed the cell membrane is compromised, and everything inside the cell is suddenly let out. The inflicting object, in this case a concrete pipe, prevents the spilling out of these harmful contents until it is removed or lifted from the muscle. You will be most concerned about the sudden release of potassium into the patient’s blood stream. Continuous ECG monitoring is key as you will be watching for ECG changes to determine the presence of excess potassium, known as hyperkalemia. The progression of changes during hyperkalemia will go from peaked T waves, to ST depression / prolonged PR intervals and eventually to a wide QRS / V-tach which is life threatening.

IMG_3684Sodium bicarbonate is a key medication used for treating crush syndrome. Calcium chloride and albuterol are other medications used.

We treat hyperkalemia with an array of medicines each carrying out a separate task. The first is by introducing a chemical buffer to offset the impending acidosis. This is achieved by pushing sodium bicarbonate. The timing of this administration is key. It must be done when the object is lifted and the sudden release of potassium hits the bloodstream. Secondly, we want to protect the myocardium which is especially sensitive to potassium by administering calcium chloride. This will precipitate if mixed with sodium bicarbonate, so use your second IV to accomplish this. Lastly, an albuterol treatment can be applied as it will help to drive potassium out of the bloodstream and back into uninjured cells. As soon as the victim is extricated be prepared to open your IV fluids wide open to obtain a systolic blood pressure greater than 100 and to give additional sodium bicarbonate and calcium chloride if ECG changes are observed. The patient should be promptly packaged and transferred to the nearest trauma center.

The key to the successful treatment of crush syndrome involves the coordination of all parties involved. You should not hesitate to call for additional resources such as another ALS unit or for a physician response team that may carry additional medication outside of your ALS protocol. As with any incident, scene safety and communication is key. Let your patient know what you’re doing and when you’ll be doing it. While time is of the essence, don’t rush through the extrication as not coordinating the administration of medication with the rescue company can have life-threatening effects. A rescue like this may be a once-in-a-career event, but your patient will be depending on your expertise to save them.

Author’s note: Always refer to your medical director and local protocols for clinical guidelines in your jurisdiction.
