Evaluating Your Rescue Service

Thursday, November 14, 2019

 Evaluating your rescue service helps ensure that the team you have selected has the knowledge, technical skills, and capabilities required to meet your company’s specific needs. In addition, a team evaluation helps fulfill the performance requirements outlined in OSHA 1910.146 and 1926.1211. If you doubt the importance of selecting a competent and properly trained rescue team, consider this disturbing statistic: more than 60% of confined space fatalities occur among would-be rescuers.

2012_Chal_h_112OSHA 1910.146 Appendix F (non-mandatory) provides a great roadmap for employers when choosing and evaluating a confined space rescue team. It contains criteria that may be used to evaluate the capabilities of both prospective and current rescue teams. (Note: Although Appendix F is “non-mandatory”, the standards of 1910.146 are not. Appendix F is OSHA’s recommended method for compliance. Learn why you should pay close attention to Appendix F, even though it is “non-mandatory.”) 

The Two Components Of A Rescue Service Evaluation:

  1. An initial evaluation, in which employers decide whether a potential rescue service or team is adequately trained and equipped to perform permit space rescues of the kind needed at the facility and whether such rescuers can respond in a timely manner; and
  2. A performance evaluation, in which employers assess the skills of a prospective rescue team or rescue service during an actual or practice rescue.

Step 1: Initial Evaluation

The initial evaluation considers:

  • A team’s technical skills as evidenced by documented training
  • Number of personnel
  • Availability
  • Timeliness based on the hazards inherent in the space
  • Whether they meet the requirements of 1910.146 (k)(2) with regards to access to personal protective equipment (PPE), training in both technical rescue and first aid/CPR, and practice in representative permit-required confined spaces at least once per year
  • The ability to notify the employer when they are unable to respond – which is of particular importance for employers using 911 as their rescue service
  • and more (see Section A, Initial Evaluation in OSHA 1910.146 Appendix F)

Step 2: Performance Evaluation

Once employers have selected one or more rescue services that meet their criteria on paper, employers should provide the rescue service access to their worksite and ask them to perform in various scenarios of the employer’s choice. Performance evaluations should be administered to a prospective rescue service, as well as to periodically evaluate your current rescue service.

Consider Using A Third Party To Evaluate Your Rescue Service

Employers may opt to use a third party to evaluate their prospective rescue service. Third-party evaluations provide a number of added benefits:

  • They are useful when employers may not have the in-house expertise necessary to administer an accurate evaluation, or for employers who prefer having a third-party evaluation as a documented, independent, and unbiased record of the rescue service/team’s capabilities.
  • They provide an opportunity for the evaluator to recommend minor changes in equipment or techniques that would enhance the capability of the team.
  • In cases where contractors will be providing their own rescue capability, third-party evaluations help ensure that all parties are doing their due diligence where permit space entry is required. Some host employers mistakenly believe that they are relieved of all responsibility when a contractor’s employees are performing the entries. But 1910.146(c)(8) and (9) place reciprocal responsibilities on host and contractor. This includes the host employer informing the contractor that permit space entry is allowed only through compliance with a permit space program meeting the requirements of 1910.146, and the contractor informing the host employer of the permit program it will be following.

Taking the time to ensure that the rescue service you choose has the proficiencies and equipment to perform the specific types of rescue required at your facility could not only prevent injuries, it could even save lives.

Non-Entry Confined Space Rescue…Are You Sure?

Tuesday, May 07, 2019
by Pat Furr, Safety Officer & VPP Coordinator

There are three generally accepted types of confined space rescue: self-rescue, non-entry retrieval, and entry rescue. Just as with the hierarchy of hazard mitigation, confined space rescue should be approached with an ascending hierarchy in mind. 

  1. Self-rescue is typically the fastest type and eliminates or at least greatly reduces the chance that anyone else will be put at risk. For these reasons, it is the first choice, but it is unrealistic to think that an entrant would be able to rescue themselves in all situations.
  2. Non-entry retrieval is the next choice. OSHA stipulates that non-entry retrieval must be considered as a means of rescue – more on that shortly.
  3. Entry rescue is the last choice, largely because it exposes the rescuers to the same hazards that the original entrant faced.

Non-Entry Confined Space Rescue…Are You Sure?

OSHA recognizes the inherent danger of entry rescue, which is why the organization mandates “retrieval systems or methods shall be used whenever an authorized entrant enters a permit space.” However, OSHA goes on to qualify this statement with two very important exceptions. OSHA requires non-entry retrieval, “unless the retrieval equipment would increase the overall risk of entry or would not contribute to the rescue of the entrant.”  Let’s examine each of these two provisions more closely... 

  1. Non-entry retrieval is required “…unless the retrieval equipment would increase the overall risk of entry.” For example, if the retrieval line would create an entanglement hazard that would impede the entrant’s ability to exit the space, then the retrieval system should not be used and entry rescue should be the choice.
  2. And non-entry retrieval is required unless the equipment “…would not contribute to the rescue of the entrant.” The key here is that the non-entry method employed must be viable. It must work when called into action.

For non-entry retrieval systems, we are relying on that retrieval line to exert forces on the entrant to pull them out of the space without help from any other device or human intervention within the space. It must perform without someone inside the space maneuvering the victim or otherwise providing assistance to the retrieval system. It has to work independently of any other forces other than what is generated from outside the space. This extremely important point is often overlooked and has resulted in many fatalities. Sadly, many of those fatalities were the would-be rescuers that attempted entry rescue when the retrieval system failed to do its intended job.

Situations that may render the retrieval system useless would be any configuration or obstruction inside the space that would prevent the system from pulling the victim clear of the space in an unimpeded manner. This could be pipework or obstructions on the floor for a horizontal movement. Likewise, pulling an unconscious victim around corners may render a retrieval system ineffective. If the entrant moves over any edge and down into a lower area offset from an overhead portal even at moderate angles, the retrieval system will probably not be able to pull an inert victim up and over that edge, even if the drop were only a foot or so.

It must be clearly understood that retrieval systems may quite possibly be applying forces on a limp human body, which, as harsh as this sounds, becomes a sort of anchor. It requires a very thorough and honest evaluation of where the entrant will be moving in the space in order to perform their planned work, and what obstructions or structural configurations are in that path. If there is any possibility that the system will not be able to pull an unconscious, inert victim along that path, then the retrieval system is NOT viable.

Human Nature vs The Best Laid Plans - An Example

Okay, so you have done a thorough and honest evaluation of the space, its configuration, and internal obstructions and determined that there is a clear path from the entrant’s “planned” work area, which is offset ten feet from the overhead portal eight feet above. Clearly, the retrieval system will be able to pull the victim out of the space should the need arise. Enter human nature, and with that comes bad decisions. Murphy’s Law has a very nasty way of changing things for the worse. 

What if, in the course of the planned work, our entrant drops his wrench down into a sump immediately adjacent to his work zone but further from the overhead portal? The fixed ladder down into the sump is only five feet and he can clearly see the wrench stuck in the sludge below. He asks for slack on the retrieval line, climbs down into the sump, bends down to grab his wrench and is nearly immediately rendered unconscious due to an undetected atmospheric hazard. 

The attendant/rescuer sees that the entrant’s head and shoulders do not reappear and within several seconds calls to ask if he is ok, only to hear no answer. He calls several more times, but still no answer. He begins to haul with the retrieval system, which consists of a wire rope winch mounted to a tripod.  The cable becomes tight and the tripod shudders and shifts slightly, then all progress stops. The would-be rescuer tries with all his might to pull the entrant’s limp body up and over the 90-degree concrete edge, but cannot. 

In a panic, the attendant/rescuer climbs down into the space and over to the sump where he sees the entrant pulled tightly against the wall of the sump but not off the floor. He climbs down into the sump to attempt to lift the entrant’s 200-pound limp body up and over the five-foot wall. As soon as he bends down to cradle him, the hazardous atmosphere overcomes him also. Two fatalities later, we wonder how our non-entry rescue retrieval system could have failed us. It would not have, had human nature not interfered and caused two people to make bad decisions. 

That story was intended to point out that things do not always go according to plan. Not only do we humans make bad decisions on occasion, but we also have accidents due to trips, slips, and falls that may send us to an area that the retrieval system may not work. Conditions inside the space may change in such a manner that it affects the retrieval system. 

For all these reasons I implore you to evaluate the capability of the retrieval system to work not only when things go according to plan, but also to evaluate the system based on the “what ifs.” For the “what ifs” that involve bad decisions, that is a matter of training and communicating to the entry team why they cannot deviate from the work plan, even to fetch that dropped wrench. For the “what ifs” that include trips, slips, falls, or equipment failures, it may be time to consider a back-up plan, which may include an entry rescue capability.

Rescuing the Rescuer: When Things Go Wrong During a Rescue

Friday, February 15, 2019
by Brad Warr, Chief Instructor

The day before 40-year-old Phoenix firefighter Brett Tarver got separated from his crew and ran out of air at the Southwest Supermarket fire, the fire service felt confident in its ability to rescue a downed firefighter. That all changed when Tarver was found unresponsive thirty minutes after his mayday was broadcast over the radio. The tragic loss of Brett Tarver on March 14, 2001, left the firefighting community wondering what it had missed.

The ensuing years of self-examination and evaluation of rapid intervention techniques and operating procedures resulted in the development of NFPA 1407: Standard for Training Fire Service Rapid Intervention Crews.
Rescuing the Rescuer: When Things Go Wrong During a Rescue
Released on December 5, 2009, the document provided a framework for fire departments to train, equip and deploy their personnel in the event of mayday. A decade later, firefighters are more prepared than at any time in history to launch a rescue operation when a brother or sister firefighter calls that mayday.

While firefighter rapid intervention techniques have continued to improve, confined space rapid intervention has not received quite as much analysis and focus for improving techniques and guidelines, despite the fact that more than 60% of confined space fatalities occur among would-be rescuers. Perhaps this is why Roco Rescue’s course “Rescuing the Rescuer: When Things Go Wrong During a Rescue”, which is being offered at the North Dakota Safety Council’s (NDSC) upcoming 2019 Annual Safety & Health Conference, sold out in a matter of days. The industry – whether they are firefighters, emergency responders, or industrial workers, recognizes the vital importance of a subject that is truly a matter of life or death.

About the Course
Taking lessons learned from both successful and unsuccessful rescues of downed firefighters, students attending “Rescuing the Rescuer” will apply those lessons to the world of confined space rescue. The day-long session will bring together rescuers of all experience levels seeking strategies for effectively responding to what nearly everyone agrees is the most stressful call a rescuer will ever receive.

The course will emphasize the following:

    • - Having a plan before something goes wrong is the only chance you have.
    • - Simple systems are easier to use in a stressful situation than complex systems.
    • - There are no systems that can replace a clear-thinking, highly-trained rescue technician.

While NFPA 1407 gives a clear picture of the responsibilities of a firefighter during a mayday, the picture is not nearly as clear for rescuers responding to the mayday call or loss of contact with a rescuer inside a confined space. The sometimes-murky relationship between OSHA and NFPA standards will be explored including a review of both the construction and general industry OSHA confined space standards (1926 Subpart AA and 1910.146).

Tackling a Rarely-Explored Topic

Although training for a downed rescuer is a topic that is rarely visited in rescue training due to time constraints and the extensive requirements rescue technicians already must meet in order to carry their title, Roco Rescue believes it is a topic that shouldn’t be overlooked. The popularity of the course in North Dakota demonstrates that this is a subject of extreme interest to the safety industry.

This is the first time Roco Rescue has offered the course in this format, but it most likely won’t be the last. Subscribe to our newsletter to be the first to learn about new course offerings. Safety professionals interested in this training who are unable to attend the sold-out course in North Dakota may also wish to explore Roco Rescue’s advanced tech level course, FAST-TRACK 120™.

Rescuer fatalities have declined in recent years, but they aren’t declining quickly enough. Let’s do our part to ensure that workers in the safety and rescue fields make it home to see their families when their work is done.

The Importance of Trench/Excavation Safety: A Conversation with Roco Rescue Chief Instructor Tim Robson

Thursday, February 14, 2019

Tim Robson’s involvement with trench rescue started in 1994 when his technical rescue team from the Albuquerque Fire Department responded to what the dispatcher called a trench event.

“When we arrived on the scene, no one was there other than a police officer and a grandmother,” Tim recalls. “She couldn’t find her grandson.”

A company doing trench work in front of her home had offered to pay the woman’s teenage grandson hourly to help them. The teenager was inside the trench when it collapsed.

The Importance of Trench/Excavation Safety: A Conversation with Roco Rescue Chief Instructor Tim Robson

“The company left, and they left him in the trench,” Tim explains. “Unfortunately, it was a fatality. When we found him, he had already succumbed.”

As a result of that experience, Tim understands firsthand the risks involved in trench work and the importance of trench safety. Now, Tim supervises Roco Rescue’s technical rescue teams across the globe and, as a Chief Instructor, leads training courses in – among other things – trench rescue.

Tim is presenting a course on “Managing Excavations” at the North Dakota Safety Council’s 46th Annual Safety & Health Conference later this month. We sat down to talk with Tim recently to find out more about trench safety and why it’s so important.

Roco Rescue: Good afternoon, Tim, and thank you for talking with us today about trench/excavation safety. Let’s start with the overarching question: How dangerous is trench work?

Tim:  Trenching/excavation is one of the major fatality-causing occupations in the U.S. right now, according to the Bureau of Labor Statistics. Of the 130 trench/excavation fatalities that occurred between 2011 and 2016, 80% of those occurred in the private construction industry.

What scares us even more is that the number of fatalities is trending up. In 2014, there were 13 fatalities in trench/excavation. In 2015, that number rose to 25. And in 2016, there were 36 fatalities. So nearly half of the fatalities that occurred over a fifteen-year period happened in 2015 and 2016. Despite the fact that the regulations have gotten stricter, the numbers are trending up.  

The Importance of Trench/Excavation Safety: A Conversation with Roco Rescue Chief Instructor Tim Robson

Roco Rescue: We’re going to touch on the OSHA regulations in a moment. First, please explain why the number of fatalities is trending upwards.

Tim: The increase in fatalities goes hand in hand with the uptick in employment and construction; as the economy improves, there’s more construction and, with that, more trenching and excavation.

In addition to more construction, there’s less space. As a country, we’re building more roads, more buildings, and more infrastructure but we have less physical space to do it in.

And in addition to doing more construction in less space, in our world, we have to do more with less. Ten years ago, there were six people working on a construction trenching job; today, there are 4, and that naturally lends itself to more safety violations.

Roco Rescue: What makes trenches so dangerous?

Tim: First, let me explain the difference between a trench and an excavation: an excavation is wider than it is deep, meaning there’s less chance of dirt collapsing because the vertical walls of the trench are sloping. If my wall slopes away from the bottom of the hole I dug, there’s less chance of that wall falling in.

A trench, on the other hand, is deeper than it is wide. If I have to dig a trench with a perfectly vertical wall, because there’s a road right next to where I’m digging the trench, I can almost guarantee a collapse.

To give readers an idea of the physics and mechanics involved when soil collapses, I often use this analogy: A typical collapse involves a couple of yards of dirt. A couple of yards of dirt collapsing into a 6-foot deep trench has the same force as a pickup truck moving 45 miles an hour. If you’re at the bottom of the trench and the soil falls in on you from 6 feet, you’re getting hit with the same amount of force as a pickup truck traveling 45 miles per hour.

When that force hits you, you can’t survive. And that’s just the force. There’s also the compression and blocked airways that the victim experiences. Every time you take a breath, the soil gets closer to your body so now it’s compressing you and you’re not able to expand your chest wall.

That’s why this is such a big concern for OSHA.

Roco Rescue: Let’s talk more about the OSHA regulations. What is OSHA doing to help reduce the number of fatalities caused by trench collapse?

Tim: Last year, OSHA put out a compliance letter urging the construction industry to improve the safety of their trenching and excavation operations.

OSHA requires that any time someone makes an excavation or trench in the ground as part of their occupation, they have to designate what’s called a competent person. That’s usually someone in a management or supervisory position who is tasked with “identifying existing and predictable hazards in the surroundings, or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.”

Roco Rescue: Besides designating a competent person, what precautions can supervisors take at work sites to reduce trench injuries/fatalities, and what can workers do to keep themselves safe?

The Importance of Trench/Excavation Safety: A Conversation with Roco Rescue Chief Instructor Tim Robson

Tim: Construction businesses have to meet the OSHA requirements for trench and excavation safety. To make the trench safe takes more time, more manpower and more labor. Ultimately, safety costs money, which is a challenge for small business in particular.

But the implications for failing to meet the requirements comes with an even bigger cost. Worker safety notwithstanding, the Department of Labor and the Department of Justice now agree that if a fatality occurs on a job site due to a willful violation of an employer, it is now a criminal act.

However, workers are equally responsible for their safety. They are also accountable for their actions. If a trained worker willfully gets into that trench, knowing it’s unprotected, they’re just as culpable as the company that put them there.

In short, the employer’s responsibility is to make sure individuals are trained at work and the employee’s responsibility to understand and follow those requirements.

Roco Rescue: What are three things attendees at your upcoming course at the NDSC Annual Conference can expect to take away from your presentation?

Tim: First, don’t take trench and excavation lightly. There’s a risk that comes with saying, “We’ve always done it this way.”

Second, they’ll leave with an understanding of OSHA’s trench/excavation competent person requirements.

Third, they’ll understand the requirements of AHJ (the authority having jurisdiction), which is generally the host employer. The AHJ is the entity that must deem someone a competent person. As an instructor, I don’t have that authority. Taking my class doesn’t qualify someone as a competent person.

Roco Rescue: How will the course you’re giving at the NDSC Annual Conference differ from Roco Rescue’s training courses in trench rescue?

Tim: At the Roco Training Center, we offer open enrollment courses in trench rescue and can even do a private training based on a specific industry. Our courses teach how to construct a trench so that it won’t collapse and, if it does collapse because of some catastrophic event, teaches workers ways to protect themselves.

Both the courses at the Roco Training Center and my course at the NDSC Annual Conference are focused on compliance, but the course at the NDSC is geared toward a broader audience.

Roco Rescue: What’s your final piece of advice for trench workers, Tim?

Tim: It’s simple: until you know it’s safe, don’t get in the trench.

Roco Rescue: Thank you so much for sharing your knowledge and expertise with us, Tim.

Confined Space Types - Are All Your Bases Covered?

Friday, November 30, 2018

Confined Space Types - Are All Your Bases Covered?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.

Confined Space Types - Are All Your Bases Covered?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 
Confined Space Types - Are All Your Bases Covered?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
Confined Space Types - Are All Your Bases Covered?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.
