I guess I am lucky. I probably did every one of those things during my flash
bulb days. I used to have a rubber strap with 12 holes in it that I attached
to my Rolleimarin. I had 100% success with flash bulbs in the ocean and at
depths up to 150’ which was my personal limit. I always used blue-coated
bulbs, even underwater.

FLASH BULBS SAFETY NOTES
Flashbulbs are much safer than the old "flash powder" they replaced. Accidents
with intact coated flashbulbs were said to be rare; nevertheless, flashbulbs
should be considered incendiary devices capable of causing bodily harm to the
user or persons nearby.
1. Static electricity may cause flashbulbs to self-ignite; consequently,
always handle bare bulbs carefully and always keep bulbs in containers until
used.-
´2.- Strong electromagnetic fields may cause flashbulbs to ignite. Exercise
care around radio transmitters (including cellular phones), and perhaps even
airline X-ray machines.-
3.- Airline regulations may prohibit flashbulbs in baggage or checked luggage.
4.- Do not use in an explosive atmosphere, such as near a gasoline station,
natural gas site, or in a coal mine.-
5.- Newer flashbulbs have a clear or blue-tinted safety coating; however, if
uncoated or if the coating has been damaged, a bulb may shatter when flashed,
producing a spray of hot glass fragments.-
6.-When using a flashbulb near people, use a safety shield over the reflector.
7.- Do not carry flashbulbs in your pocket. Static electricity or other forces
may cause the bulb to flash, causing severe burns. Many retired press
photographers have leg burns because of this unwise practice.-
8.- A flashbulb in contact with another bulb which flashes will also flash.
Take care when handling a box (or bag!) of bulbs.-
