Mixed P-P's (Propane/Propylene) Page: 3/9
: Use an extinguishing agent suitable for the surrounding fire.
Fire-fighting media and
instructions
Extremely Flammable. Do not extinguish fire due to probable explosive reignition. Shut
off source of flow, if possible. Use appropriate extinguishing media for any secondary
fires. Small fires can be extinguished with dry chemical or carbon dioxide. Water can be
used to cool fire-exposed containers, structures and to protect personnel. If a leak or
spill has not ignited, ventilate area and use water spray to disperse gas or vapor and to
protect personnel attempting to stop a leak.
Risk of explosion by shock, friction, fire or other sources of ignition.
: Fire-fighters should wear appropriate protective equipment and self-contained breathing
Special protective
apparatus (SCBA) with a full face-piece operated in positive pressure mode. Fire-
equipment for fire-fighters
fighters' protective clothing will only provide limited protection. Dangerous when exposed
to heat or flame. Vapors form flammable or explosive mixtures with air at room
temperature. Vapor or gas may spread to distant ignition sources (pilot lights, welding
equipment, electrical equipment, etc.) and flash back. Vapors may accumulate in low
areas. Vapors may concentrate in confined areas. Flowing product can be ignited by
self generated static electricity. Use adequate bonding and grounding to prevent static
buildup. Runoff to sewer may cause fire or explosion hazard. Containers may explode
in heat of fire. Irritating or toxic substances may be emitted upon thermal decomposition.
For fires involving this material, do not enter any enclosed or confined space without
proper protective equipment, which may include NIOSH approved self-contained
breathing apparatus with full face mask. Clothing, rags or similar organic material
contaminated with this product and stored in a closed space may undergo spontaneous
combustion. Transfer to and from commonly bonded and grounded containers.
: FLAMMABLE.

Section 6. Accidental Release Measures
: Immediately contact emergency personnel. Eliminate all ignition sources. Keep
Personal precautions
unnecessary personnel away. Use suitable protective equipment (section 8). Do not
touch or walk through spilled material.
: If facility or operation has an "oil or hazardous substance contingency plan", activate its
Environmental precautions
procedures. Stay upwind and away from spill. Wear appropriate protective equipment
including respiratory protection as conditions warrant. Do not enter or stay in area
unless monitoring indicates that it is safe to do so. Isolate hazard area and restrict entry
to emergency crew. Extremely flammable. Review Fire and Explosion Hazard Data
before proceeding with clean up. Keep all sources of ignition (flames, smoking, flares,
etc.) and hot surfaces away from release. Contain spill in smallest possible area.
Recover as much product as possible (e.g., by vacuuming). Stop leak if it can be done
without risk. Use water spray to disperse vapors. Spilled material may be absorbed by
an appropriate absorbent, and then handled in accordance with environmental
regulations. Prevent spilled material from entering sewers, storm drains, other
unauthorized treatment or drainage systems and natural waterways. Contact fire
authorities and appropriate federal, state and local agencies. If spill of any amount is
made into or upon navigable waters, the contiguous zone, or adjoining shorelines,
contact the National Response Center at 800-424- 8802. For highway or railway spills,
contact Chemtrec at 800-424-9300.
