Product-specific hazards and other issues : :
Suitable extinguishing media:
- SMALL FIRE: Use dry chemicals, CO2, water spray or alcohol-resistant foam.
- LARGE FIRE: Use water spray, water fog or alcohol-resistant foam.
Unsuitable Extinguishing Media : Do not use solid water stream/may spread fire.
- Note: High temperatures/catalytic agents may produce flammable isobutylene. Thermal
decomposition may produce carbon monoxide, formaldehyde, other toxic gases, and flammable
Specific hazards during fire fighting
- Flash point less than freeze point.
- When mixed with air and exposed to ignition source, vapors can burn in open or explode if
- Heat/contamination can release extremely flammable isobutylene gas.
- Diluting with water may not suffice to raise flash point above ambient temperatures.
- Vapors may be heavier than air.
- May travel long distances along the ground before igniting and flashing back to vapor source.
- Move containers from fire area if you can do it without risk.
- Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
- Blanket with alcohol–resistant foam.
- Cool containers with flooding quantities of water until well after fire is out.
- Withdraw immediately in case of rising sound from venting safety devices or discoloration of
- Always stay away from tanks engulfed in fire.
- For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw
from area and let fire burn.
Special protective equipment for fire-fighters
- Wear positive pressure self-contained breathing apparatus (SCBA).
- Structural firefighters protective clothing will only provide limited protection.
Product-specific hazards and other issues
Personal precautions :
- Use personal protective equipment.
- Ensure adequate ventilation.
- Remove all sources of ignition.
- Evacuate personnel to safe areas.
- Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low
Land spillage : Prevent product from entering drains.
Spillages in water or at sea : Prevent further leakage or spillage if safe to do so. If the
product contaminates rivers and lakes or drains inform
Methods for cleaning up
- Extremely flammable liquid/frozen form may also be highly flammable.
- Eliminate all sources of ignition.
- All equipment used when handling this product must be grounded.
- Do not touch or walk through spilled material.
- Stop leak if you can do it without risk.
- Prevent entry into waterways, sewers, basements or confined areas.
- A vapor suppressing foam may be used to reduce vapors.
- Use clean non-sparking tools to collect absorbed material.
- Water spray may reduce vapor; but may not prevent ignition in closed spaces.
- Contain spillage, and then collect with non-combustible absorbent material, (e.g. sand, earth,
diatomaceous earth, vermiculite) and place in container for disposal according to local / national
General information :
Advice on safe handling
- For industrial use only.
- Keep container tightly closed when not in use.
- Use only non-sparking tools.
- Containers must be properly grounded before beginning transfer.
- Carefully vent any internal pressure before removing closure.
- Wear recommended personal protective equipment.
- Extinguish all ignition sources.
- solate, vent, drain, wash and purge systems or equipment before maintenance or repair.
- Observe precautions pertaining to confined space entry.
- Check atmosphere for explosiveness and oxygen deficiencies.
- All electrical equipment should be grounded and conform to applicable electric codes and
