The Latest In Fall Protection... Andy Speidel of MSA Safety on "Roco Chats With the Experts"

Wednesday, October 16, 2019

Pat Furr (Roco Rescue): Good morning Andy and thanks so much for joining us today.

Andy Speidel (MSA): Oh, it’s my pleasure Pat. Thanks for inviting me.

PF: We’re going to talk about all things Fall Protection. We’ll cover the latest advances in equipment and talk about how they’ve impacted how we work at height. We’ll also touch on some recent and upcoming regulatory changes, get your take on ways readers might be able to improve their fall protection programs, and discuss how to work effectively with a safety equipment rep.

AS: Sounds great, Pat.

The Latest Innovations in Fall Protection Equipment

PF: MSA is a leader in the design and manufacture of fall protection equipment and systems, so tell us about the latest advances in equipment that may just make the end user’s job easier and safer all at once.

AS: The last several years have seen significant advances in the use of modern design and manufacturing techniques as well as the use of lighter and stronger materials such as aircraft aluminum and synthetic fibers. This has allowed MSA V-Fit Harness manufacturers to innovate and come up with products that are lightweight, easy to employ, multi-functional, and most importantly, these products are appealing to the authorized person, which ultimately encourages them to use it.

Our design team has put a lot of emphasis on making our harnesses more intuitive to don. The new lightweight materials we use make it possible to not only meet all the standards, but also to provide superior comfort, flexibility and adjustability - which ultimately allows the user to more easily don the harness.

PF: Of all the latest and greatest pieces of kit, which ones jump out as the most exciting for you?

AS: We’ve taken a huge step forward with our personal fall limiters (PFLs) V-EDGE™ Leading Edge Personal Fall Limiter through the use of Kevlar and Dyneema rope, which gives them the strength and abrasion resistance to be used in leading edge applications, while at the same time making them much lighter than earlier generations that used wire rope. Additionally, the interface allows the PFL to be used on a variety of harnesses. It’s a simple aluminum pin that slides through a web loop on the harness to make the connection.    

PF:  One of the scariest scenes I encounter when doing site visits are these Frankenstein, cobbled together horizontal lifelines. Some of them would struggle to hold up the laundry, let alone arrest a fallen worker.

AS: Horizontal lifelines must be designed, inspected and installed under the supervision of a qualified person, which I am willing to bet, some of the ones you’ve seen were not. We at MSA, as well as a few other manufacturers, are producing user-installable, pre-engineered temporary horizontal lifeline systems. These systems are typically constructed of wire or synthetic rope. They come in a variety of lengths and are very easy to deploy and recover. We have a unique system where two workers Horizontal Lifeline on the same horizontal lifeline can easily bypass each other without having to disconnect. This allows increased mobility and decreases worker interference while still maintaining 100% fall protection.

PF: I would imagine these systems include comprehensive user instructions that mandate the anchor strength requirements and detail clearance requirements?

AS: That is correct. The instructions outline the parameters for use and include calculations for clearance requirements based on the span of the line between anchors, the number of workers on the system, and the type of lanyard they’re using to connect. Our systems have either a turnbuckle or a pulley tensioning system, making it very easy to adjust the sag for the proper tightness of the line.

Equipment Advances Provide New Options For Re-Thinking Work-At-Height With The Hierarchy of Fall Protection In Mind

PF: One of the things that I see with the better fall protection equipment manufacturers is that they truly make an effort to educate the competent and qualified persons as well as the program administrators on their options for not only providing a safe and compliant solution for their employees, but also on appealing to the authorized persons. I think the big three for end users are lightweight, ease of use, and multifunctional. When you make a site visit or a presentation, it must be gratifying to see the light bulbs go on as your attendees hear the options available to them.

AS: It is and although my job entails selling equipment, I don’t approach my visits with ‘making a sale’ as my primary objective. I want to hear from the potential customer what their needs are and what their big concerns are.

PF: Are there any common themes in those discussions?

AS: Many people assume a fall arrest system is the only solution, when really we ought to take a step back and approach the problem using the hierarchy of fall protection. It’s not always possible, but quite often there’s a solution on a lower step of the hierarchy that restrains a worker from falling, or that brings some of the work to the ground – which is usually the safest solution.

PF: That reminds me of an exercise I often do when I’m presenting on fall protection or giving a talk at a conference. I ask everyone in the audience to close their eyes and visualize whatever comes to mind as I state two words: fall protection. Then I ask them what they were visualizing.

AS: Let me guess… they say harness and fall arrest lanyard.

PF: Yep, those are the most common answers.

AS: That’s why it’s important for us to listen to the customer, assess their situation, and discuss solutions that work best for their application and provide the least amount of risk to the worker. For example, we have a lot of customers who need to regularly access a flat roof on an older structure with no perimeter guardrails or parapets. When I tell them about retrofitting guardrails such as our VersiRail system, they worry about the costs. When we discuss other options such as active restraint or even fall arrest systems and the time it takes to set up and the limited mobility they often provide, they start to see the advantages of a passive fall protection system which doesn’t require authorized person training or specialized equipment. And compared to the average cost for one fatal incident, let alone the tragedy of such an occurrence, suddenly the cost for a perimeter guardrail system sounds affordable.

VersiRail® Guardrail Systems

However, for those who still can’t justify the cost, we do have non-penetrating temporary anchors that work great on flat roofs for both active restraint and fall arrest anchors. Our Constant Force Post is one such example.

Ways To Improve Your Fall Protection Program

PF: What do you see as a less obvious deficiency in fall protection programs beyond the more common shortfalls such as general lack of compliance?

AS: One area that’s often overlooked is the need to read and understand the instructions for use for equipment and systems. This information is essential to ensure correct and safe usage. Not all SRLs are designed for leading edge applications. Not all personal fall limiters can be mounted at foot level. Even something as simple as proper fit of a full body harness varies from harness to harness. That’s why I encourage employers and fall protection program owners to work with a manufacturer who can help them standardize their equipment and provide follow-up support and training.

PF: That’s definitely a concern. Do you have any others that you would like to address?

AS: Greater focus on authorized person pre-use inspections. Unfortunately, OSHA only requires an annual periodic inspection be performed by a competent person for most fall protection equipment. Some systems such as horizontal lifelines need to be inspected by a qualified person. MSA recommends periodic inspection by a competent person on most pieces of equipment at 6-month intervals and depending on environmental conditions and type of wear and tear the equipment is exposed to, it can be even more frequent. We count on the authorized persons doing a thorough pre-use inspection, but often these are not being done as they should.

PF: Oh I agree 100%. I’ve seen some downright scary equipment that had no business being used on the job. My suggestion for program administrators: have your authorized persons perform the pre-use inspection on their coworker’s kit and vice versa. Nobody likes to get called out for having failed to do their job, so trading harnesses so that I inspect yours while you inspect mine creates an incentive to make sure yours is in serviceable condition.

Retrieval Self-Retracting Lifelines: A Primer

PF: I'd like to hear your thoughts on a piece of equipment that many end users are either unaware of, or don’t fully understand its capabilities. I'm talking about a retrieval self-retracting lifeline (RSRL).

AS: RSRLs are great in specific applications. Sometimes we are confronted with multiple hazards as defined by OSHA and ANSI. For instance, we may have a significantly high vertical entry into a permit required confined space. This involves at least two different OSHA regulations and requires certain protections as mandated by those different regs. We need to protect the entrant from the fall hazard and have a means of retrieving the entrant in the event of an emergency. In the case of the confined space regulation, if the vertical entry is greater than 5’, then the retrieval system must be a mechanical means of retrieval that is of sufficient hauling ability to lift the entrant up and out of the space. RSRLs satisfy both needs by providing fall arrest and retrieval capability.

PF: What types of anchors or anchor systems do you recommend for RSRLs in order to support a vertical confined space entrant? 

XTIRPA System for Confined Space Entry

AS: A tripod is a good choice, but for situations where there’s limited space, or some other obstruction that prevents the use of a tripod, the MSA Xtirpa system is a great way to mount either the RSRL or a straight winch system. It’s easy to set up and extremely lightweight. It’s compatible with a large assortment of mounting systems such as the manhole collar shown below, ballasted cantilever mounts, floor bolted mounts and many other options.

 

Regulatory Changes: OSHA’s Walking and Working Surfaces

PF: Let’s talk about the changes to the OSHA Walking and Working Surfaces regulation and specifically the changes to fixed vertical ladders and the shift to vertical ladder safety systems as a move away from cages and wells. What are the options for employers to retrofit these systems (without getting into the mandated timeline issues)?

AS: We have two primary ways these systems can be installed. Latchways® Vertical Ladder Lifeline Kits The first way is we can come out and install it for you, whether it’s one of our kits or it’s a custom-built system. For all applications greater than 90’, we facilitate an MSA-authorized installer to perform the installation. The second way is if a customer purchases one of our kits, they can opt to handle the installation themselves. We have kits up 90’, so they cover a lot of applications. All that’s really needed are some basic mechanical skills and the ability to follow the instructions provided within the user’s manual.

PF: I really think ladder cages are a poor solution for worker safety. I certainly wouldn’t want to fall through a ladder cage and get hung up in it. I can only imagine the horrific injuries that would result. I’m glad that OSHA has decided to make them obsolete, but I’m concerned that many employers will wait until 2036 approaches before making the move to a safer system.

AS: I agree and share your concern, Pat. Another way to meet compliance is to use a top mount davit with an SRL and tagline. This solution is an option when evaluating a vertical ladder safety system. Some companies go with this option because they’re easy to install and don’t require the user to have a front chest d-ring on their harness. V-TEC™ Mini Personal Fall Limiter Another option would be to use a twin leg personal fall limiter and clip along from rung to rung.  

Fall Protection in Residential Roofing

PF: You and I have worked together in the past up in your neck of the woods, presenting information to a variety of groups on fall protection equipment. As more safety managers see these new systems and equipment, they are very apt to provide a safer yet more user-friendly solution to their authorized workers. However, we are still seeing a particular segment of the construction industry lagging in providing compliant fall protection for their workers. That industry is residential construction and in particular residential roofing.

AS: Yes, residential roofing is clearly a segment that needs us to demonstrate that there are great solutions that not only keep their employees safe, but also make it easier for workers to do their jobs. I remember a recent conference where you had a steep angle roofing mock set up, and seeing the smiles on the faces of attendees when they realized they could let their harness support their weight instead of trying to curl their toes and hold onto the sheathing while laying felt. I think for most of them it was quite a revelation. I believe you had two different systems set up. The positioning system was simply a 5/8” lifeline with a short shock-absorbing lanyard attached to a manual rope grab. And on the other exposure you had a temporary horizontal lifeline along the peak with a leading edge SRL attached to it.

PF: Yes, but the SRL was not just any SRL. It was your V-Edge Leading Edge SRL.

AS: Yes, it was great to see the attendees’ reactions as the V-Edge followed their movement along the horizontal lifeline. In addition to the leading edge feature of that particular SRL, it also has a built-in roll-cage around the clear cable housing which allows the entire unit to pivot around a floor mounted anchor. This keeps the direction of pull or tension of the cable directly in line with the user and SRL. It works great on steep angle roofs attached to a horizontal lifeline to keep the device aligned vertically with the user as they move about the roof.

Viewing Your Safety Equipment Rep As A Resource To Help Solve For Safety Concerns

PF: There’s certainly a lot of innovation happening in the fall protection equipment market. How do you recommend employers think about worker safety in the context of these new technologies?

AS: I think it’s a high return on investment exercise for employers to invite safety equipment representatives into their facility to look at different applications, almost like an audit. A good equipment rep specializes in staying on top of all the latest developments in the dynamic world of equipment and safety systems. It’s tough for an employer to do that on their own, so the safety equipment rep ideally will partner with the employer to evaluate all their concerns and help them prioritize. I’ve found employers are often pleasantly surprised with the solutions folks like me come up with, either because they didn’t think a solution existed, or because they were surprised we could make the workplace safer without impeding production.

PF: Andy, I want to thank you for having this chat with Roco Rescue and I know we have just scratched the surface of everything fall protection. I hope our readers have found this both informative and entertaining, and perhaps got them thinking about their own fall protection needs.

AS: Thanks so much for inviting me to join you today Pat. We at MSA want to ensure employers are armed with all the information they need to select the fall protection equipment and systems that best suit their needs. We love talking about how our products can be used in various applications, but most importantly how they can be used to ensure workers make it home safely.

The ROI of Safety

Tuesday, August 13, 2019

I hear it very often from students, attendees at safety shows, and during site needs assessments. It is usually something the safety representative says, but more and more, I hear it from the employees, and it goes something like this: “Our management wants us to be safe, but when it comes time to sign the check to pay for it, all of a sudden they have second thoughts.”   

In my experience, investment in safety is often cyclical; it ebbs and flows with the macroeconomy generally, and with a specific industry sector's performance in particular. Investment in safety tends to wane when profits are lean.

One of the old TV commercials put it clearly.  It was a motor oil commercial and the mechanic says, “You can pay me now for an oil change, or pay me later for an engine rebuild.” The broader message is: it's much cheaper to invest in preventative measures now than to pay for the failure later.   

 An article published in NSC’s Safety + Health magazine earlier this year points out some strategies that may help you as a safety professional demonstrate to your management the economic sense of investing in proactive safety.

“Advanced” Confined Space Rescue

Tuesday, June 11, 2019

By Chris Carlsen, Albuquerque Fire Department

Having worked and been an instructor in the rescue field, I am often asked, “what are some advanced rescue techniques in confined spaces?” My response is always, “It depends where you think you are as a team, because advanced can mean many different things.”

Obviously there are confined space rescue scenarios that require a higher level of proficiency and teamwork than others. However, I like to begin by asking a team to do a self-assessment, as outlined below, and to think of “advanced” confined space rescue as anything that advances the ability of a team to perform as rescuers.

Is your team in the CRAWLING stage, meaning you have a trained team but the only time you touch a piece of equipment or do some rigging is during an annual refresher? Then “advanced” for your team means relearning the fundamentals every year. Practicing anchor rigging, building basic mechanical advantage systems, packaging patients in litters and drag devices, setting up SCBA or SAR systems and understanding the importance of atmospheric monitoring and ventilation strategies. All the basic tools you need to get the job done!

Is your team WALKING, having dedicated team members with solid fundamentals that attend regular training evolutions? Then “advanced” can mean organizing team equipment for a more efficient response, pre-rigging standard set-ups for rapid deployment, practicing compound and/or complex systems, identifying and preplanning confined spaces, defining team roles in an ICS type structure, and conducting full scenarios from response to termination.

Is your team RUNNING, with experienced team members who are looking to be challenged? Advanced for you is getting creative and locating spaces that are difficult to reach, difficult to access, and/or challenging to work in. Teams like this will benefit from having time restraints on training exercises to build pressure and increase the speed with which people work. Other ideas would be to limit the availability of equipment so the team has to problem-solve and prioritize actions, or add new pieces of equipment that provide more efficiency or increase safety.

Every one of the teams I just described is capable of making a successful confined space rescue today. But first, what do we consider a successful confined space rescue? For me, it is performing the rescue while providing for the safety of our team and the persons we are responding to. If we can do that, then we have been successful.

Over and above the basics of a successful rescue, what separates good teams from better ones is their efficiency and ability to solve complex problems. The more complex the rescue scenario is, the less efficient the team is going to be… unless they have experienced the scenario before or can relate it to something they have done. And where can they get experiences needed to build confidence and the mental files they can draw from? Training, training, and oh yeah training! The best teams build a sort of muscle memory that derives from all the exposure to various situations they have experienced. I have a quote scribbled on my wall that says:

“A rescue isn’t successful because of what you did today, it was the years of training that led up to the rescue that made the difference.”

I’m not sure who said that, but when I read it, it stuck, and I have spent my professional career trying to make sure I was ready for a rescue today. So I ask, are you ready? Do you know how complex the next rescue problem is going to be?

In order to be ready, we must have a solid grasp of the basics for confined space rescue. I’m not talking about building mechanical advantage systems or selecting the best anchor point. Yes, those skills are necessary, but I’m talking about managing your TIME. Because in confined space rescue, time is one of the greatest factors between a rescue or a recovery. One of Roco Rescue’s great Chief Instructors, Mike Adams, really helped me understand this concept in a simple way. He broke the entire rescue down into four parts.

  1. Put your hands on the patient: Everything you do initially must drive towards this goal. The faster you can do that, the faster you will have a complete understanding of the complexity of the rescue. Keep it simple and get in there once you have provided for the safety of your rescuer.
  2. Care and Package: Do good patient care, and treat the things that are life threatening first. Once you know the life threat, then you’ll know how much time you have to work with. Then package for the environment and the injury.
  3. Extricate: Build a world class rescue system or just put your hands on the patient and move! Either way your team should be ready to perform once the patient is ready to move. The type of space and the orientation of the patient will usually dictate the how and what.
  4. Lift and/or Lower and turn them over: Once the patient is out of the space, lift / lower them to ground level and turn them over to EMS. This is typically less hazardous but still just as important if you have a critical patient.

Focus on these concepts in your next confined space training; see how well your team performs, and ask plenty of questions.

Did you stumble a little bit? Was there some confusion about the plan or about who was doing what job? If so, that’s ok! Talk about it, sort it out and do it again - that is what training is for! On the other hand, maybe you cruised right through the scenario and everyone was pretty quiet. If so, perhaps that’s because your jobs are well defined and your team knows what is always coming next. Or was it just because you have done the same drill from the same space for the last 10 years? Either way it’s time to turn up the heat and start challenging your team to get them to the next level.

If you’ve trained with us at Roco Rescue, then you’re familiar with our version of the K.I.S.S. principle: “Keep It SAFE and SIMPLE.” I’ve used it many times, and it works, but as our depth of knowledge grows and the complexity of the incident grows, the “devil” is really in the details. The masters of any craft only became masters through practice. So you want to know some Advanced Confined Space Rescue Techniques? You want to be a Confined Space Rescue Technician?

Train, Learn, Practice.

And as always, be safe.

Rescue Challenge Spotlight - Valero Wilmington

Friday, May 10, 2019
 
“It’s an intense two days. It’s exhausting and hard, but it’s also a lot of fun. I tell all my guys, ‘you’ll work your butt off at Rescue Challenge, but you’ll love every minute it.’”

- Randy Pickering, Asst Fire Chief, Valero Wilmington Refinery
If you’ve ever flown from LAX Airport, there’s a good chance the fuel in your airplane was refined at Valero Wilmington, a leading independent refinery of transportation fuels and petroleum products.

Assistant Chief Randy Pickering oversees training for the refinery’s 40+ rescuers, who are divided into four teams by shift. Made up of operators, maintenance techs, welders, electricians and more, these individuals sign up for the additional responsibilities and training because they love the challenge of it, and because they want to be there to help their co-workers in case of an emergency.

Rescue Challenge Spotlight - Valero WilmingtonValero Wilmington has attended Roco Rescue Challenge nearly every year since 1991 and has a stellar track record in the annual event. The safety and effectiveness of the team is a commitment taken very seriously by the group, and Challenge helps them hone their skills to the max, enhancing their culture of safety.

The team of ten rescuers who travel to Baton Rouge each October have earned the privilege to represent Valero Wilmington by winning an in-house rescue competition.

“We use Roco Rescue Challenge as a motivator for all our rescue teams and a reward for those who are selected to go,” says Randy.
From unusually challenging high-line scenarios to seemingly impossibly small confined spaces, Randy is proud of the way his team thinks on their feet and works together in unfamiliar rescue scenarios. For Valero Wilmington, each Rescue Challenge has been a rewarding learning experience, as well as an opportunity to bring home a coveted trophy (the team’s good-natured, friendly SoCal exterior conceals a competitive streak…).

The Roco Rescue Challenge has one open team slot remaining.

Observers welcome! 
If you’re not ready to sign-up a team, join us as an observer. Watch the teams as they tackle some very challenging scenarios – it’s a great learning experience.

Non-Entry Confined Space Rescue…Are You Sure?

Tuesday, May 7, 2019

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.
