Suspension Trauma: 3 Must-Know Myths

suspension trauma

Suspension trauma has a few different names—Harness hang, harness-induced pathology and orthostatic intolerance (the medical term). Consequences can be fatal, and it’s important to be aware of symptoms and ways to prevent its onset.

Suspension trauma has its fair share of misconceptions—One of the biggest is that it’s a myth. 

In this article, we discuss three myths that surround suspension trauma you must know. 

MYTH #1: SUSPENSION TRAUMA ISN’T REAL

It is! Suspension trauma happens when a worker’s movement is vertically suspended, restricted and upright for an extended period of time and lose consciousness.

But why does this happen? Blood pools in the legs and makes them swell, while blood pressure drops. Typically, when orthostatic intolerance sets in the victim faints so blood will re-circulate through the body—A worker in restrictive fall arresting equipment can’t do this. 

It can be minor, too—A common example is people who are still for long periods of time and faint, or feel dizzy when they get up. 

Now, imagine you’ve arrested a fall, don’t have a rescue plan and first responders are still on the way. 5 minutes, 10 minutes, and now 25 minutes pass. You know that suspension trauma can set in after just 30 minutes. Time is ticking. You’re covered in sweat, you feel dizzy and terribly nauseous.

Finally, you’re cut down and pass out, unconscious. You’re in the hospital—There’s paperwork, lost-time and incident investigations to happen. Who knew a little slip could cause so much trouble?

Yes, you’re alive, but next time, you’ll definitely have a rescue plan. And suspension trauma is real.

MYTH #2: SAFETY HARNESSES MAKE SUSPENSION TRAUMA EXTINCT

Suspension trauma is still a reality. Yes, education, training and equipment reduce injuries and fatalities in industrial workplaces, but prevention is still a priority. Look at it this way—Vaccines exist for illness like the measles, but people still contract it when they don’t use preventative measures. 

Individual factors increase a worker’s risk to develop the trauma, and its effects are not easy to predict person-to-person. 

These factors include: 

  • Individual’s ability to manage anxiety/stress
  • Harness selection & fit
  • Poor training
  • Previous injury or illness 

This is why training is vital. It’s important to teach employees not only what happens when you use the wrong PPE, but psychological coping mechanisms to help a worker deal with a potential fall. Proper training will also emphasize the importance to continuously move your legs in specific ways to maintain circulation—It’s important The right safety harness and leg straps will allow the worker to move 

MYTH #3:  WHEN THE HARNESS IS OFF, IT’S OVER 

Okay, so when I take the safety harness off I’m fine, right? Wrong.  

Workers in vertical positions must receive medical attention immediately after release. In past suspension trauma cases, victims have died after the harness comes off—This is known as ‘rescue death’.

Some doctors think it’s caused when blood tries to circulate through the body at its normal pace, and can’t. Did you know leg muscles are one of your body’s auxiliary pumps? When legs hang, motionless and upright, it pinches the arteries and blood can’t flow to crucial parts of the body, like the heart and brain. 

  • Leg circulation
  • Heart circulation
  • Brain circulation 

Fortunately, like we mention above, industrial environments benefit with the right personal protective equipment (PPE) and training to prevent suspension trauma. Recorded injuries from suspension trauma are somewhat rare—But training and proper PPE are key to this.

A body harness that doesn’t fit properly, is fit with the wrong accessories or is uncomfortable, does more harm than good. Remember—Suspension trauma does exist, the right safety harness help prevent it and negative effects of suspension trauma can linger after the harness is off. It’s important to train yourself and workers (even those who may not be working at heights) of the risk and procedures to take before, during and after a fall.

PPE Fall Protection in North America

PPE Fall Protection: the early lanyard

PPE Fall Protection devices were used in the early 20th Century by many professionals, although they used rope lanyards made of natural fibers, such as manila hemp, and simple body belts with no shock-absorbing properties. Clarence W. Rose–who early in his career was a window washer–became a pioneer in fall protection when he started the Rose Mfg. Co. in 1934 and began producing safety belts and lanyards for window washers. On Nov. 24, 1959, Rose was awarded a patent for an easy-to-use cable connector for safety belts that also had some shock-absorbing properties (U.S. Patent 2,914,139). Listed in the patent was a statement that the connector could, among other things, “be adapted to slip somewhat responsive to a sudden jerk as when the safety rope checks the fall of a wearer and thereby eases the shock to the wearer incurred by checking the fall.”

PPE Fall Protection: shock-absorption major leap forward

Joseph Feldstein, manager of Technical Services at MSA, which purchased the Rose Mfg. Co. in 1996, said the idea of a shock absorber was a major step forward in protecting against the large braking forces generated in arresting falls, especially during Rose’s time.

“If you can imagine, workers with a simple belt and lanyard arrangement that was common up until that point would be exposed to a fall that could not only damage them internally because of the forces exerted to the soft tissues of the abdomen around the belt, but also you could generate such forces that you could separate the lanyard,” he said.

Rose continued to develop his shock-absorbing concept and was awarded several patents for newer and better shock absorbers. Ultimately, his designs influenced the creation of the modern-day shock absorber. Rose also received many other patents related in some way to preventing or protecting workers from falls. An example is the patent for an early “Ladder Climber” harness system (U.S. Patent 2,886,227) that contains two hook lanyards that are both attached to a harness. While ascending or descending, a worker grasps one hook in each hand and secures them over alternating ladder rungs.

Decades later, the industry would see the emergence of locking snap hook connectors and full-body harnesses, both gaining much more acceptance in the 1980s. In 1990, OSHA enacted regulation 1910.66. Craig Firl, product marketing manager in Hardgoods for Capital Safety-USA, said appendix C in this regulation was the key to getting several areas of fall protection technology up to date.

“Even though that particular standard at that time allowed for non-locking-type hooks to be used in a fall protection-type system, they recommended the locking type to be used because they were safer hooks and more compatible,” Firl said.

PPE Fall Protection: more hardware than ever

Feldstein agreed, adding that the acceptance of the locking snap hook led to the creation of a whole new series of connecting anchorage systems: straps, D-rings, and more. “And that’s continued to evolve to its current state, where we now have personalized anchorage connectors for almost every application, whether it’s building construction or general industry,” he said. Even though body belts were still allowed, Feldstein said appendix C acknowledged that OSHA recognized full-body harnesses as a major innovation in fall arrest. “Belts are still permissible in positioning, but in a fall, you definitely want to be protected by a full-body harness. It distributes the load across your chest and the bony mass of your hip, where your body is most capable of absorbing a blow, and it protects the soft tissue of the abdomen,” Feldstein said.

Two years after 1910.66 arrived, the ANSI committee released standard Z359.1, the key fall protection standard in use today. Most notably, it required the use of full-body harnesses and self-locking snap hooks. Firl said this voluntary compliance standard put pressure on OSHA to recognize that its existing standard needed updating and encouraged the completion of another fall protection standard for the construction industry, Subpart M, in 1995. According to this standard, as of Jan. 1, 1998, the use of body belts and non-locking snap hooks was prohibited.

During the ’80s, Self-Retracting Lanyards (SRLs) gained in development and use. They had been developed in the 1950s for offshore oil production in the North Sea but quickly became a common component in fall protection systems worldwide. Feldstein said SRLs became so valuable because they allowed workers to be protected along a much greater length of travel, increasing productivity without sacrificing safety. He described a scenario for rail car workers:

“Workers could be protected from the ground level and all the way up to the top of the rail car while they were working along the train’s length because the SRL could be mounted mobilely overhead. So that afforded a new type of protection for all types of workers in transportation, everything from rail cars, truck load-outs, and air craft maintenance.”

Regarding fall protection’s future, Firl and Feldstein said they believe comfort will continue to advance. Firl also foresees advances into niche markets with specialized materials and components, similar to the vacuum anchors’ progression into the airline industry for maintenance work on aircraft, whose surfaces can’t be penetrated with traditional-type anchors.
“In the past, a harness was a harness. It didn’t really matter if it was for construction, or utility work, or warehousing, it was a harness,” he said. “Now, you’re starting to see more specialized gear. . .  As an example, in the utility segment, you would see extensively the use of flame-resistant materials . . . because they’re concerned about heat resistance; they’re concerned about being able to resist arc flash and so forth.”

Hercules’ Tips: Is your Safety Harness Comfortable?

safety harness from 3m at hercules slr

A safety harness is a necessary evil for many workers, working across many different industrial trades. We understand—nobody likes to be uncomfortable during their work day.

However, proper equipment, like safety harnesses are key to getting the job one, reducing costs, injuries, and most importantly—getting home safely. Although necessary, heavy equipment can leave you sore, tired and less productive by the day’s end.

Lighter harnesses have been produced to reduce discomfort and give more mobility, however this hasn’t solved issues like injuries from fatigue, strain or repetitious movement. Workers must still carry heavy equipment, typically for 10+ hours a day—issues improper safety harnesses can exacerbate.

Check out this infographic to find out the real cost of injuries, wearing improper equipment (or wearing it improperly) and some of the biggest complaints surrounding safety harnesses. It also includes how to choose a safety harness that provides support and comfort, so you can remain productive and safe during your work day.

Find all your safety harness needs at Hercules SLR—including custom-fitted harnesses, fall protection training and more.
