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
´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
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
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.-

"......Perhaps someone else on the list has come in contact with or knows
a Rollei branded guard/diffusor...
Some Rollei prices list and complete catalogues from the '50s' don't
mention a Rollei guard/ diffusor within the accessories for the Rolleiflash
1 (1952-1959)and I couldn't find it for the Rolleiflash 2 (1959-1969),
despite Rollei made electronic flashes with diffusor from the '60s. The
Rolleiflash for the Rolleimarin shows a protection for the lamp, but they
were dedicated units.
