Hazardous Materials Flashcards
what are the properties of LPG gas
Oderless**
Flammable
Heavier Then Air (1.5 to 2 times heavier - will sink)**

how should you approach LP gas fires or leaks
whenever possible * Upwind
What distance should be kept for personnel not engaged in operations for LP gas emergencies
atleast 1000 feet from the front and rear and 500 from the sides
At LP gas fires when can you put out the fire
do not extinguish until the leak has been stopped, except under extreme conditions
Where do tank failures under fire conditions usually occur for LP gas tanks
Vapor Area
before LPG tank failure what happens within the tank
The rise in pressure will cause an increase in fire or a rise in noise level or both
may blister or bubble
Can you move a tank involved in fire
no attempt should be made unless a specific condition develops that makes it desirable to move . Move UPRIGHT*** never drag
what is effective in dispersing LP gas vapor?
water spray should be used asap directing the spray stream across the normal vapor path and to a safe area
what class of hazardous material is compressed gas
2
How quick can a breve occur
in a matter of minutes

What are the properties of natural gas
Flammable
non toxic
Lighter than air*** (will rise)
Compressed natural gas cylinders are subject to failure but not do what
not bleve because they do not contain liquid
