Development of safety features for survival training

What safety measures currently used, what is
planned and what measures could be taken into account
when training and when considering safety of
underwater escape training
HUET LIFTING APPARATUSBack‐up power, very important, especially in
countries where power failure is common.Best to have immediate back‐up to avoid any
delaysDifferent ways to achieve back‐up liftingMWH back‐up power (UPS) to lift simulator in
case of general power failureIn MWH the fastest way in practice is to help the
trainees out, by the trainer inside the simulator
UPS system provides immediate power
Turns on automaticallyBattery technology improved
in recent years, expected life time up to four years
HUET LIFTING APPARATUScrane double wiredouble brakerequired reliable lifting speed and what the
crane manufacturer can deliver.crane double motor, in addition to the above (in
case motor failure)safety line or back‐up wire (in case lifting wire
breaks)
HUET ASSESORIESCameras for monitoring and recordingin the pool and inside the simulator; if
something happens possible to analyse situation later.
The pool underwater camera useful for the crane operator, in case of emergency situation.
CAMERA INSIDE SIMULATOR
HUET ASSESORIESEmergency lighting for doors & windows useful for the instructor and the trainees to see
where the emergency opening are under waternormally helicopters that operate over water
have (HEELS ‑ Helicopter Emergency Egress Lighting System) HEELS as standard
A typical installation of HEELS consists of an array of LED lamps within a sealed silicone tube placed around the escape hatches or doors

HUET ASSESORIESEBS; used only if required to be used by trainees in real
life.EBS very important for trainees to learn how to use
properly (to avoid breathing in water when e.g upside down and need to empty mouth from water)
EBS, problematic, small bottles can be risky to use, fo fill reliably, find and locate in emergency, may fall out (of mouth), limited volume of air, may push trainees to hold breath and lung rupture
EBS no possibility to blow out water and danger of sucking in water into lungs
HUET ASSESORIES
panic buttonsquick release doors & frames (Doors useful
when you must help a trainee out fast)
TRAINER SKILLStrainer skills; need to be very comfortable in
water, and to leave as last person from simulator, calm nature, good communication skills
trainee assessment, possibilities to identify potential dangers and panic attacks when under water
water awereness; need to gradually introduce the trainees into the underwater escape training environment, using e.g. shallow water escapte trainer (SWET)
TRAINER SKILLSgood introduction to survival skills prior to the
training in water and inside simulatorsafety diver skills (needs to know what happens
inside to be able to predict problems before they occur)
radio and/or other communication between instructor inside the simulator, safety diver and crane operator
Raising water awarenesswith SWET
OTHERmedical equipment and skills at the training
pool, e.g.First aid equipmentDefibrillatorOXY‐Box for oxygen treatmentPersonnel trained to use equipment
OTHERThe instructors, divers and staff skilled in first aidRisk assessment lifting out of pool, ambulance
routes, transport, local hospital, decompression chamber
Always complete technical check‐up and trial runs to check all equipment before training
Listen to the opinion of safety divers during exercises in the dark/low visibility, ability to get immediate illumination on the surface
Regardless of the availability of the safety equipment and skill levels, most important is to
train properlyfollow instructions keep the instructions simple
Thank You!Thank you!
Merci!
