(2) TB 30- Organic Peroxide Fires Flashcards
If LARGER AMOUNTS of organic peroxides are seriously EXPOSED and CANNOT BE PROTECTED from involvement, the proper tactic would be to ___________.
CONSIDER the use of FIXED HEAVY STREAMS and WITHDRAW all personnel from the potential blast area.
(If fire REACHES the organic peroxide, EXPLOSION IS IMMINENT, and the area must be rapidly EVACUATED.)
What kind of Permit is required to store, process or use any amount of organic peroxide?
Division 4 permit
(Organic peroxides must be stored separately from other products)
Organic peroxide fires:
If a valid Division 4 Permit is not in effect for storage of organic peroxide at the said occupancy, PROMPTLY notify ____________
The Fire Prevention Bureau, Engineering Unit, BY TELEPHONE, followed by an F-44 Memorandum
Organic peroxide fires:
If on nights, weekends or holidays a valid Division 4 Permit is not in effect for storage of organic peroxide at the said occupancy, promptly notify _____ through MFC
Fire prevention officer
Organic peroxide fires:
Organic peroxides should be stored in ____ (different/the same?) containers used by the manufacturers for shipping the material.
The same
Organic peroxides are HIGHLY FLAMMABLE and are classed as “________” in the Fire Code.
Unstable Materials
Recognition of organic peroxides is dependent upon the DEPARTMENT OF TRANSPORTATION LABELS which include:
-Yellow Labels
-Organic Peroxide Oxidizer
(The usual shipping containers encountered consist of boxed (WOOD/FIBER) or drum (FIBER/METAL).
If VERY SMALL QUANTITIES of organic peroxide are INVOLVED in a fire, the proper tactic would be to _________.
Apply water spray streams from as FAR as possible OR from an explosion PROTECTED location
Organic Peroxides properties:
-At high temps can EXPLODE
-considered a non-typical oxidizer because they contain both FUEL and OXIDIZER (will decompose at relatively low temps)
-found as solids (usually as powder), liquids or pastes
-highly flammable
The most COMMON Organic Peroxides
-Benzoyl peroxides
-M.E.K. peroxide
-Lauroyl peroxide
-Decanoyl peroxide
-T-Butyl peroxide
(Most end in “-yl”)
When fire occurs in the VICINITY of organic peroxides, the proper tactic would be to _________.
Maintain a COOLING WATER spray over the CONTAINERS to prevent overheating or contact with fire.
Disposal of peroxides involved in a fire should not be attempted WITHOUT technical assistance.
Clean-up and salvage operations should not be attempted until __________.
All of the peroxide has COOLED COMPLETELY.
