The Safety Equiment and Survival branch of the Royal Navy was, and is, responsible for  Safety Equipment ie:- Parachutes, liferafts, flying clothing and ejection seat drogues etc. Sounds simple! There's a lot more to it than that.
Many people see service aircraft flying overhead and take them
for granted?   Mechanics, Technicians, Artificers, Air traffic controllers, Aircraft handlers, Meteorlogical  and  Photograpic sections, Firefighters, Cooks, Stores, Medical and Motor transport.....and so the list goes on and they all play their part in keeping the aircraft flying safely and reliably. However, from time to time accidents do happen, and that is when the Safety Equipment Branch comes into its own. Teaching aircrew how to use a strop, or these days a modern rescue jacket as in this picture but there are still procedures to follow, to ensure complete safety at all times.

Parachute packing is an art in itself but it is not just

the packing, repairs and quick release boxes. There are different types, for different aircraft. Liferafts, single seaters, five man, twenty man, plus ancillary equipment and survival packs etc. Flying clothing, lifejackets, helmets, overalls, anti G suits, Charging CO2 bottles, Sewing by machine and by hand....and so the list goes on, everything has to be done by the book and
counter signed after being checked.  Pilot training, before flight briefings, wet dinghy drill, Survival training. Desert, jungle and arctic sea training.
The former Seafield Park near Fareham Hants was where  the Safety Equipment and Survival Training School was based and later transferred to H.M.S. Sultan at Portsmouth. However, the branch has now become fragmented.  Each Naval Air station had it's own Safety Equipment Section. Ships Ark Royal, Eagle,
Bulwark, Hermes, Invincible, they all had their own SE sections and each squadron had it's own SE personnel. There is a lot more to the branch than listed here, but it gives people a rough idea what we were/are all about.
