Helmets - Protecting your noggin at a fraction of the price of brain surgery

Typical 4-point suspension
ANSI type I protection
Traditional hard-hats used by construction workers aren't much more than a skid lid to keep your hair on your scalp.  That isn't to say it isn't a good thing, especially for us 'folically challenged' folks.  However, when you flip one of these over and study the inside you suddenly realize that the shock absorption mechanism is anything more than a few nylon ribbons that are supposed to 'predictably' fail and take some of the wham! out of the slam!-bam! of a falling object.

There is no joy in scraping your skull along the bottom of a low-lying air duct, sprinkler pipe, or cross-bracing steel.  The pain is excruciating, and dripping blood from the catwalk is poor manners.

A few years ago, well actually ALOT of years ago, helmet manufacturers realized that adding a layer of crushable foam (typically styrofoam) to the inside of a helmet would increase the energy dissipation significantly.  We first saw this technology applied to motorcycle and auto racing helmets, and then to bicycle helmets.  It eventually made its way into rock climbing helmets, and from there into the world of construction helmets.
KASK Super Plasma Helmet interior view - ANSI type II protection.
Note the two layers of padding:  both Styrofoam and a fabric covered foam cushion.

Conventional hard hat with 4-point chin strap
Although you can buy accessory chin straps for cheap hard-hats, the chin straps don't always stay attached, they are difficult to find and buy, and they frequently cost more than the hard-hat itself.  In the theatre and show production industry we seem to spend a lot of time either bent over (hold the jokes please . . .) or working at height.  Both of these work situations demand that your PPE remain secured to your person.  You don't want you hard-hat falling into the scenery that you are painting, and you don't want it to fall from the truss or catwalk you are working upon.  Either way, when your hard-hat departs your head you are exposing yourself to injury AND you may be exposing the inattentive and unwilling participant below you to the full impact of your helmet on their head.  Hopefully, they are wearing some head protection, too!

Single chin strap accessory
So, if you drop you helmet to the stage floor below, will it damage it?  Yes, it will.  The next stop for that hard-hat is the dumpster.  You probably can't see the micro-fractures that impact set-up in the plastic, but I'd never trust the helmet to protect my brains again.  So, for a $5 big-box ANSI type I hard-hat, this is no big deal, but when you start wearing a $85-$150 ANSI type II hardhat, then protecting your investment (both your PPE and your brains) is a bit more of a concern.
KASK Super Plasma - ANSI type II protection

Myth:  Rock climbing helmets aren't OSHA compliant.  Any helmet that meets the ANSI/ISEA Z89.1-2009 or 2014 standard is acceptable.  It may not look like Bubba's typical construction site hard-hat, but if it meets the standard and is labelled as such, then it's legal.

So, what can yo do to keep a cool head and be stylin' on truss?  Get one of those really protective and 'I'm a professional' looking ANSI type II helmets and wear it!  The two most popular climbing helmets are the Petzl Verex Best and the KASK Super Plasma.  Bright colors are recommended.  If you need to black it out for a show (common for truss follow spotlight operators), just have your costume department sew-up a black spandex cover for it.

Bottom line:  Unless your want your brains to become Zombie food, protect them.  No replacement parts are currently available.

There is no shame in protecting your brain!

Cirque du Soleil suffers tragic loss of performer during show accident

MGM Grand, Las Vegas, Nevada - Saturday, June 29, 2013.   In a yet-to-be-explained equipment failure, one of the aerial performers in Cirque du Soleil's fell about 50 feet from above the show's massive 3-axis moving stage into the forestage pit during the fight scene at the end of a performance.  The pit is nearly 4 stories deep.  Sarah Guyard-Guillot, 31, mother of two, came loose from her safety cable and disappeared into pit unexpectedly.  The show was halted, the audience informed that they could obtain replacement tickets for a future show, and were dismissed.  The show has been suspended indefinitely pending an investigation into the root cause of the accident.  Guyard-Guillot, mother of two young children, was pronounced dead at a hospital late Saturday night.  It is reported that her safety harness was intact with her costume when she was recovered from the accident site.  She was a trained acrobat and aerialist, originally from Paris, France.  She had performed in the industry for about 22 years.
Sarah Guyard-Guillot  1979-2013

This is the first performance-related death that the troupe has experienced in over 30 years of show production.*  Guyard-Guillot was one of the original performer's in the show when it opened in 2006, and had performed the show since then.

An extremely through and rigorous safety program is entrenched in the companies' culture, so this has been shock to those that work the shows in a tight-knit group.  Cirque's safety managers have been very transparent and informative by sharing their safety culture and knowledge at numerous industry events like the annual USITT convention, LDI convention, and UNSCA's Entertainment Innovation Conference.

The death comes at an unfortunate time for the circus, a reportedly $1 Billion (US) company which employs 5,000 people globally, including 2,000 at its headquarters in Montreal, Canada.  Cirque maintains around 19 touring productions in operation worldwide, yet has recently reduced it's workforce and is trying to reign-in its expenses.

Cirque du Soleil's founder, Guy Laliberté, said in a statement:  "I am heartbroken. I wish to extend my sincerest sympathies to the family. We are all completely devastated with this news.  Sassoon was an artist with the original cast of KÀ since 2006 and has been an integral part of our Cirque du Soleil tight family. We are reminded, with great humility and respect, how extraordinary our artists are each and every night. Our focus now is to support each other as a family. "

~*~*~*~*~*~*~*~
* In 2009, a Cirque performer died in Montreal after sustaining head injuries from falling off a trampoline during training. Oleksandr Zhurov, who was 24, hailed from the Ukraine and was known as Sacha. There also have been several injuries during Cirque performances in the last decade. Actors have been hurt during performances of "Zumanity" in Las Vegas, Nevada; "Corteo" in Portland, Oregon; and "La Nouba" in Orlando, Florida.

The same night as the deadly fall during , Cirque's newest show, "Michael Jackson: ONE," held its opening night performance at the Mandalay Bay Resort and Casino in Las Vegas. That production experienced its own trouble the previous week.

On Wednesday, June 26, 2013, Cirque reported that an acrobat taking part in one of the final preview performances suffered a mild concussion after slipping through slack rope in the show's "Stranger in Moscow" scene. That performer, who is expected to return to the production, missed a protective pad below the actors and landed hard on the stage.

FOLLOW-UP
OSHA FINES CIRQUE DU SOLEIL AND MGM GRAND
FOR PERFORMER'S DEATH AND OTHER CONCERNS

2013-10-29  - Nevada OSHA has finished its investigation into the death of Sarah Guillot-Guyard, the Cirque du Soleil performer who fell 94 feet during the climactic scene of Ka on June 29, 1013 and later died.  OSHA determined that accident happened when the wire rope she was suspended from broke. According to the report, the wire rope “was severed due to the rapid ascent of the performer, ultimately causing the rope to be freed from the sheave/pulley and scraping against a shear point.”  OSHA officials cited Cirque du Soleil with six proposed citations and more than $25,000 in fines and MGM Grand with three citations and a $7,000 fine.  Cirque du Soleil and MGM are appealing the fines.

One of the citations for Cirque du Soleil includes a failure to “protect or prevent Ka employees from striking an overhead grid during the Ka show at the Ka Theater.” Reporting for the Las Vegas Sun, John Katsilometes wrote that “This matches reports from those familiar with the Ka staging and fatal incident that Guillot-Guyard did hit the metal grid over the stage as she ascended high above the Final Battle scene, which jarred the rope connecting her to her harness.” Katsilometes also reported that Cirque du Soleil will be appealing the fine:

    In a statement that also referenced Cirque’s internal review of the incident, [Cirque du Soleil spokeswoman Rene-Claude Menard] said: “Cirque du Soleil completed an exhaustive review of its safety policies and procedures in the wake of the tragic accident involving Sarah. We have redoubled our efforts to ensure the overall diligence and safety of our performers and crew. We have received and reviewed the OSHA citations. We have initiated the appeal process as part of OSHA’s administrative protocol. Safety always has been the top priority for Cirque du Soleil, its performers and crew members.”

On the KTNV website (www.jrn.com/ktnv/news/Cirque-du-Soleil-MGM-Grand-cited-in-KA-performers-death-229744241.html), Krista Hostetler listed the citations OSHA has proposed. They are:

Summary of Cited Violations

Cirque du Soleil:
- NRS 618.375 (1): A General Duty Citation was issued because the employer did not protect or prevent KA employees from striking an overhead grid during the KA show at the KA Theater. $7,000 proposed penalty.

Bucket Bails Break Bones

The ubiquitous plastic bucket - it shows-up unannounced, hangs around like an unwanted house-guest, and finally spills it guts and gets thrown in the trash.


Aside from the obvious bad rigging (you did see that, didn't you?), plastic buckets have a serious weak point:  The metal bail that forms the carrying handle.  This is nothing but a piece of bent steel wire that hooks into the plastic rim of the bucket.  Given sufficient (over)loading, the plastic bucket can deform and let-go of the bail (literally tearing the plastic), and/or the metal bail can bend and lose it's grip on the bucket.  Either way - this thing is going down.

We just love to over-stuff our carry-alls, and when you add-up the weight of hand-tools, nuts & bolts, drills, and all that other crud you forget to clean-out, the weight can become significant.  This wouldn't be such a big deal if you were just carrying this across the stage or shop, but there are times we forget logic and tie a rope on thee a try to hoist them up to elevated work locations.  Not such a good idea - What was once just going to fall  a few inches onto your foot now becomes a bomb falling from overhead - maybe 20 feet, maybe 50 feet, depending where you are going with it.  Either way, this can be deadly should the handle fail.

Safe lifting of materials is usually best accomplished when the lifting system encompasses the load, this places the load on the lifting device and not on the object being lifted.

The folks at The Circus Company (I guess circuses use these things to haul food and water for the animals) have a simple, yet effective solution:  Build a load-rated sling designed to fit those 5-gallon buckets we are so fond of.

These slings are rated for 200 Pounds and are inexpensive (relative to the cost of a new noggin').  The handle is constructed of reinforced Nylon, and has an extra layer across the hoist point.  It's pretty snazzy, too!

Don't be a doofus and drop your load  - secure it!

Going Down? Self-Rescue Beats Hanging Around

The US OSHA and UK HSE Fall Protection standards include a requirement that a rescue plan be in-place before climbing operations begin.  Calling 911 is not a rescue plan.  When a worker is hanging in a fall protection harness they can be subject to suspension trauma, so getting them down to terra-firma (the more firmer, the less terror) is the first priority.

Suspension trauma is the shut-down of the circulatory system due to the constrictions placed on the body by the fall protection harness.  There are kits that you can supplement on your climbing gear that will deploy a short set of bootstraps that tie back to the suspension D-Ring and will allow you to 'stand-up' and take some of the pressure off of your leg and waist fittings, but this is only a temporary solution to the problem.

The OSHA / HSE rescue requirements allow for self-rescue.  This can be a real time saver, as getting to a rescue kit, taking it up to an attachment point above the fallen worker, and reaching or rappelling down to attach the kit, then lowering the fall victim to the ground can be very time-consuming.  Here are three self-rescue solutions that are worthy of consideration:

--------------------------

The DUES 3700 is a small hands-free speed controlled descender that can be pre-attached to your climbing gear and deployed as-needed, or it can be pre-deployed and ready to go.  It can be used with up to 500 feet of rope.

The 3700 features quadruple-redundant braking, automatic speed-limiting technology, hands-free descent, and a speed control dial to control descent with just two fingers. Plus, the ropes can be replaced so it’s cost-effective and versatile.  The unit can be reused repeatedly.  More info at:  www.deusrescue.com/products/devices/deus3700.aspx

--------------------------

The Latchways PRD (Personal Rescue Device) is a backpack module that is fully-integrated with the climbing harness and preconnected to the fall arrest lanyard.  If you fall, you just reach up to your shoulder and pull a release cord that unlocks the descender and it lowers you to the ground.  Current models have a 65 foot rescue rope, and longer options are forthcoming. One drawback to this system is that you must send the unit to a Latchways service center to have it reset for the next use.  More info at:  www.latchways.com/personal-rescue-device-US

--------------------------

The Petzel EXO personal escape system is a manually operated self-braking descender packaged with rope, carbiners and a easy carry pouch.  Originally designed for the NYFD, this is a lightweight and reliable solution.  The unit can be reused repeatedly.  More info at:  www.petzl.com/en/pro/verticality/descenders/exo-individual-evacuation-system-0/exo-eashook

Keeping Dents Out of Co-workers Noggins

Ty-Flot, makers of tool restraint lanyards, has introduced a new way to work with drop prevention equipped tools and tool belts.  The Quick-Switch system allows the use of a short lanyard that fits between the tool and the worker's wrist so that long floppy lanyards are eliminated.


Conventional lanyards that are tied-off to work belts and climbing harnesses must be long enough to facilitate using the tool at extreme reach positions.  These longer lanyards allow dropped tools to travel farther and pick-up more speed before they are restrained.  If the tool lanyard loops over a railing, it can swing back and strike a worker severely.

The Quick-Switch lanyard connection on the short lanyards allow tools to change hands, and be stored without presenting large loops to snag on protruding objects around the worker.

Don't Drop What You Are Doing - Get a Grip

Objects at Heights: Love Stinks But Gravity Hurts. 
Free Webinar • Duration: 60 minutes

With the exception of Chuck Norris, hurricanes, and halitosis, there’s little more dangerous than a plummeting object. Unfortunately, most tools don’t come with wings, so when you have a butter-finger type of day (and we’ve all had ‘em), the tools and equipment you rely on can quickly turn into plummeting little (or big) bombs of destruction. Aerial safety goes beyond your standard fall protection. In the past, objects at heights hazard-planning has been an afterthought – or not even a thought. Today, regulators and professionals acknowledge the serious, life-threatening risks of falling objects and are instilling rules to ensure proper precautions are followed in the workplace

This educational webinar will overview:
  • Objects at Heights Safety and how it is part of Safety at Heights planning
  • Awareness of the costs of dropped objects and other Objects at Heights hazards
  • Best practices for Objects at Heights within the Hierarchy of Controls 
Seminar brought to you by: EHS Today (The Magazine for Environment, Health, and Safety Leaders) and Ergodyne Work Gear.

Working At Height is a Complex Issue

Event Industry News published an interesting article about Working at Height.  This is something that is almost always required during the mounting, running, and strike of most events.  However, the definition of what ‘working at height’ actually is should serve as a reminder to organizers of the important role played by event safety consultants.  Sadly, most events in North and South America don't have independent oversight of personnel safety, they tend to lump the task in with the event security work and fail to see the difference between the two roles. No show is so important that workers should ever be put at risk, yet they are routinely asked, nay, TOLD to do things that place riggers and ground crews unnecessarily in danger of injuries, or worse.

Chris Hannam from the UK safety consultant firm Stagesafe says that some of the myths surrounding health and safety are absurd, often sensationalized by the media and driven not by the UK Health and Safety Executive, but by insurance companies.  He says that it’s important not to be mislead by incorrect health and safety myths, but instead to keep things simple and read the correct guidance.  In his column, Chris provides the essential guidance for event professionals when working at height.

Safety involves equipment, the surfaces it will be operated upon, and the personnel performing the work.  His article can be found here:

Ladder Safety Should Be A High Priority

Ladder Safety is an ongoing concern in the performing arts as more and more venues are constructed with inadequate access to the working parts of a production facility. Powered Manlifts are one possible solution, yet many administrators somehow think that they are less expensive than a trip to the hospital.  Even with a Powered Manlift, ladders are frequently found around many workplaces because they are a convenient way to access many items

Make a concerted effort to train students, co-workers, and administrators about Ladder Safety so that there is a consistent perspective on the subject throughout your organization.

The AFL-CIO's Construction Trades Department has produced an 8-page Ladder Safety Guidebook that can be downloaded free at: www.sprick.net/ARES060808/LadderSafety.pdf
