Do you have a rescue plan for your permit-required confined space entry work? One that has been practiced regularly and revised if necessary? If you can't emphatically say "yes" to these questions, consider this sobering statistic: Over 60% of confined-space fatalities in multifatality confined-space incidents involve the would-be rescuer. This is often due to poor and/or quick decision-making when things go wrong... in other words, not sticking to the plan (if one exists). Having a plan in place that accounts for all the "what-ifs" can prevent these fatalities from happening.

What elements should a permit-required confined space rescue plan include? Roco Rescue Safety Officer Pat Furr outlines these in an article in Safety + Health (the official magazine of the National Safety Council).

I’d like to share 3 innovations that I see as having game-changing potential for rescue operations in the next decade. None of these 3 are brand new, but recent advances have earned them a place in the rescue team’s toolkit.

Drones

One of the most dangerous aspects of rescue work is the time pressure that exists to reach victims before they succumb. Unfortunately, we often don’t have eyes on the victim and can’t communicate with them, so we must make assumptions about their condition. Rescuers frequently put themselves at greater risk in order to reach a victim quickly. Drones have the potential to give rescuers a clearer picture of the victim’s condition and possibly even communicate directly with them. This allows rescuers to appropriately pace their actions, to know what tools to bring to effectively treat the victim, and to avoid the same pitfalls that befell the victim. Not to sound too gruesome, but a drone can also help determine if it is a rescue or a recovery operation, which has obvious implications for the rescue operation’s pace and risk exposure.

Drones can also serve as reconnaissance tools during natural disaster rescue operations. This is a much faster and safer method of mapping an area than sending in rescuers and can be done while rescuers are pre-planning. Drones won’t completely replace manned helicopters, but they are safer, more available and more cost effective. Many drones are outfitted with software and GPS that produces maps and can geo-tag objects within centimeters of their actual location. Many also have thermal sensors, which allow for transmission of key data, and are designed to withstand extreme temperatures. Look for drones to play an increasingly important role in helping rescuers during the aftermath of hurricanes, floods, fires, tornadoes, blizzards and just about any adverse weather event.

Drones are also a great tool for getting a visual on victims at extreme height, such as on towers or tall buildings. Oftentimes these victims are not clearly visible with binoculars, making it difficult to assess their physical condition.

Drones are even being designed specifically for use in confined spaces. Previously, drones were susceptible to damaging crashes from flying in tight spaces. Also, the radio frequencies that control them were often unable to penetrate thick concrete walls. But engineers are addressing these issues and have come up with the Flyability Elios 2, for example, which features a spherical cage to protect the drone from slamming into walls. It also boasts a transmission system capable of working beyond line-of-sight, thus enabling the drone to fly into structures made of concrete, steel, and other materials.

These drones will likely help confined space rescuers in two ways… First and foremost, sending a drone instead of a human into a confined space for an inspection will become the norm, and with fewer humans doing entry work, there will be fewer incidents requiring rescue. Second, when a rescue is called for, a drone can scout the space for a rescuer, provide a visual assessment of the victim and transmit atmospheric data to the rescue team. All of these are invaluable pieces of data that will make the rescue operation safer and more effective.

Portable Powered Winches

One key skill in rope rescue is the ability to build mechanical advantage (MA) systems so that they can efficiently raise / lower / haul weighted objects using rope. I don’t expect this skill to become obsolete, but the use of portable powered winches will make rope rescue less dependent on rescuer-constructed MA systems. Winches have been around for a long time, and are a standard tool for arborists and tower workers, but they haven’t been used much in rescue until recently, as significant improvements in battery power and materials have now made them reliable and durable enough for use with human cargo. Because they are battery powered and compact, they are especially useful when manpower and operating space are limited. They are lightweight and therefore easy to pack and carry as part of a rescue team’s gear cache.

SkyHook Rescue Systems and Atlas Devices (whose APA-5 is pictured above) are among the leading manufacturers in this space. In the same way that pocket calculators take the legwork out of doing long division, winches make building efficient hauling systems that much faster and easier. That said, there are a few important caveats to consider when thinking about using portable powered winches in rescue operations. Safe use requires rescuers to factor in the weight capacity and to understand proper winch placement in a system like a tripod. Improper placement has the potential to unbalance and tip a tripod. Rescuers also need to know how to rig up a back-up rope system should the main line fail. Finally, the use of powered winches must consider the added risk of injuring the human load or damage to the system components should it become hung up. For these reasons, it is absolutely critical that the rescue load be visible to a dedicated monitor who can call an immediate stop to the haul should the load become hung up. Nonetheless, portable powered winches definitely have the potential to improve and change rope rescue operations, and I expect we’ll be training with them a lot more frequently in the coming decade.

Two-Tension Systems and Team-Style Friction Devices

The use of two-tension systems (sometimes called mirrored systems or dual main systems) is fast becoming a high-interest technique in the rescue world. Why? Since both ropes are tensioned, the load is shared, which decreases the risk of load-induced equipment failure. Also, in a two-tension system, there is no slack in the second line, so the potential free-fall distance is greatly reduced. Additionally, two-tension systems have double the mechanical advantage of traditional systems, making hauling more efficient.

As these two-tension systems become more popular, team-style friction devices (like the Petzl Maestro) will be a fixture in a rope rescuer’s toolkit. These are critical components of a two-tension system because they provide the three primary functions two-tensioned systems require – friction control, belay, and haul. By providing two mirrored tensioned systems during a lower, the forces on either of the systems are essentially cut in half. This greatly reduces stress on the system and is more easily managed by the operator working with heavier rescue loads. Also, as mentioned previously, using a mirrored 3:1 or 5:1 Z-rig through a Maestro or other similar device during hauling operations will double the mechanical advantage compared to using a single haul system. Applying two 3:1 mirrored MAs results in a 6:1 total MA. This can reduce the manpower required for the haul team, which is beneficial for a variety of reasons.

There exists a healthy debate in the rescue world over the pros and cons of two-tension systems versus more traditional single-main / single-backup systems, but it appears as though two-tension systems are winning the argument and will become the standard in the coming decade. 

Two-tensioned systems hold the advantage in many of the rope rescue operations where dedicated mains / dedicated belays are currently being used. But there are still a few situations where the dedicated main / belay system will remain the best-practice approach. It is important to train with both types to determine what works best for your response area. Two-tensioned systems require a different type of coordination between team members, but they are quickly mastered with practice.

Embrace the Changes Technology Brings Us!

Technological advances are impacting every sector of industry from microprocessors to rescue gear. Precision engineering and advances in materials have made the gear rescuers use today smaller, lighter, smoother, faster and safer than ever. Some advances are incremental, and you only recognize the progress when you look back over a long time-horizon. For example, a retired U.S. Army Ranger recently told me that when he was in Ranger School in the 1960’s, he rappelled off 60-foot towers and the only descent control technology he had was a pair of leather gloves! Clearly, we’ve come a long way since then, and the quality of devices a rescuer can use to safely control their speed during a descent is remarkable. Other technological advances are more immediately impactful and noticeable. Whether it happens slowly or rapidly, we as rescuers have a duty to always be evaluating innovative new equipment and techniques so that we can keep improving the overall effectiveness and safety of rescue operations.

Petzl is set to release a brand new rescue descender called the Maestro in late January 2020. We’ve been testing it out for a few months and wanted to share our findings. We think our readers will find this particularly relevant since the Maestro is designed specifically for technical rescue.

The Maestro is a rescue descender that provides the user with a high degree of control in a variety of applications. We found it to be adept at both lowering and hauling, and it’s rated for handling relatively heavy loads (550lbs for the S model and 615lbs for the L model).

The control comes from design elements like the integrated brake and a faceted sheave, which adds friction areas for the rope so that slippage is reduced and braking power is enhanced. The device gives the user additional control over the amount of friction by changing the angle of the rope as it feeds into the device, or by wrapping the rope around the cleat/brake on the outside of the device. The intuitive and ergonomic handle and the wide range of friction options put the Maestro at the head of the class for controlling heavy rescue loads during lowering operations.

The Maestro transitions from lowering to hauling very nicely. We like that it gives the user an auditory cue – it clicks in haul mode as the uni-directional pulley sheave moves with the rope. It’s easy to set up a 3:1 z-rig using a pulley and a rope grab like the Petzl Rescucender. This is where the Maestro really shines, thanks to the efficiency characteristics of its design. Its large-diameter sheave coupled with sealed ball bearings only allow the pulley to rotate in one direction, creating a progress-capture system that minimizes loss of haul-gains. As the user hauls the load, the Maestro’s auto-lock feature locks in the progress made, and the user can then extend the rope grab back out and continue hauling.

We see the Maestro as being very well suited for use in dual main rope systems. These systems require a device capable of consistent and dependable friction control while providing the high efficiency hauling functions that the Maestro excels at.

The Maestro is the most intuitive device in its class. From hand and body positioning, to loading the rope into the device, the Maestro offers a high safety margin with ease of use.

Many combination devices try to do everything and end up doing nothing particularly well. Not so with the Petzl Maestro. It’s a very capable device for descent control, progress capture and belaying. It’s a multi-function tool that’s easy to use and transitions between functions beautifully. For all these reasons, we recommend the Maestro as a tool that technical rescuers should strongly consider adding to their equipment cache.

Note: The Maestro is currently available in limited quantities. Use this link to check for availability.

 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.

OSHA 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.
