I am a retired Derbyshire Fireman ,I was trained and used the Proto set, I did most of my training at Chesterfield Mines rescue station -
I am trying to recall the donning procedure
went something like this
While the dresser buckles you
take out plug and mouthpiece too
open main valve
take a reading
nose clip bypass do your breathing
if nose clips tight protect your sight
rest assure you will be alright
never had the full facemask
just googles that steamed up and the way to clear woulkd be rotate the sweat within them.
the mouthpiece made you drool saliva from the corners of your mouth
if you were on your back sometimes protosorb would get stuck in the valves and sometimes pass into your mouth
think they were set at 2,5 litres per minand you would have to operate relief valve
all oxygen cylinders were recharged with manual pump
those were the days
Interesting site. I am currently helping Ruby Mathieson with selling Ray's dive helmet collection. Collection/Inventory includes many MK 12 RB, helmets (most crush decommissioned), and MK 12 suits and coveralls. These are all being sold. Total system MK 12 "Jake" can be built up.
Thanks for info and photos from the salvage ship Artiglio and the searching for s/s Egypt.
My relative, captain Gustav Hedbäck on the swedish salvage ship "Fritiof" from Gothenburg (Röda bolaget) in June 19923 reported to Mr Sandberg in London that he had localized the wreck of Egypt. Britt
Well done, thanks for this. I was hoping you would also have something on the ELIZABETHVILLE - the losts diamonds ship torpedoed 1917 off France (Bay of Biscay). Will keep searching. Thanks again. Great pics.
Hello. I have enjoyed your site very much. I was responsible for submarine diver lock out operations using the system for 2 years 1976 to 78 from Star Pisces operating in the North Sea. I'm interested in putting together a paper for the Historic Diving Society in the U.K. To ensure it's not lost. I have the operating manuals but no photos. I'd like to use some if yours.would this be ok?
Best wishes. Mike O'Meara
