Fire-fighting measures

Suitable extinguishing media:
Small fires :
- Use dry chemical, CO2, water spray or regular foam.
Large fires :
- Use water spray, water fog or regular foam.

Unsuitable extinguishing media :
- Do not use a solid water stream as it may scatter and spread fire.

Specific hazards during fire-fighting :
- Keep away from all ignition sources
- This material releases flammable vapors at well below ambient temperatures and may form flammable mixtures with air.
- When mixed with air and exposed to ignition source, vapors can burn in open or explode if confined.
- Vapors may travel long distances along the ground before reaching a source of ignition and flashing back.
- Diluting with water may not suffice to raise flash point above ambient temperatures.
- Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
- Containers can build up pressure if exposure to heat; cool with flooding quantities of water until well after the fire is out.
- Move containers from fire area if you can do it without risk.
- Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
- Heat may build enough pressure to rupture closed containers/spreading fire/increasing risk of burns/injuries.
- 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.
- Sustained fire attack on vessels may result in a Boiling Liquid Expanding Vapour Explosion *BLEVE).
- Notify authorities immediately if liquid enters sewer/public waters.
- Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.

Special protection equipment for fire-fighters :
- Wear an approved positive pressure self-contained breathing apparatus and firefighter turnout gear.
- Structural firefighters protective clothing will only provide limited protection.

Accidental release measures

Personal precautions :
- Use personal protective equipment.
- Ensure adequate ventilation.
- Eliminate all sources of ignition.
- Evacuate personnel to safe areas.

Land spillage :

Spillages in water or at sea :
- If the product contaminates rivers and lakes or drains inform respective authorities.

Methods for cleaning up :
-Highly flammable liquid and vapor.
- Notify fire and environmental authorities
- Release can cause fire/explosion/health/environmental hazards.
- Eliminate all sources of ignition.
- Evacuate/limit access.
- Ensure adequate ventilation.
- 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 regulations.
- For larger spillages on water contain with booms or barriers, use surface acting agents to thicken spilled materials.
- Remove trapped material with suction hoses.

Handling and storage

Advice on safe handling :
- For industrial use only.
- Use only non-sparking tools.
- Carefully vent any internal pressure before removing closure.
- Metal containers involved in the transfer of this material should be grounded and bonded.
- Wear recommended personal protective equipment.
- Do not overfill containers which may burst on freezing.
- Thaw frozen containers only at room temperature.
- Containers must be properly grounded before beginning transfer.
- All equipment must conform to applicable electrical code.
- Handle used containers with care - residue is flammable/poisonous.
- Isolate, vent, drain, wash and purge systems or equipment before maintenance or repair.
- Extinguish all ignition sources.
- Check atmosphere for explosiveness and oxygen deficiencies.
- If any residual product may be present, total encapsulating impervious protective suits, gloves, and boots should be worn.
- Observe precautions pertaining to confined space entry.
- Provide grounding/equipment conforming to electrical codes.
- Bonding and grounding measures may not be enough if nonconductive flammable liquids are involved.
- Do not pressurize or expose empty containers to open flame, sparks, or heat.
- Keep container tightly closed when not in use.
- Keep in properly labeled containers.

Fire-fighting class :
- Highly flammable liquid and vapor.

Requirements for storage areas and containers :
- Store only in tightly closed, properly vented containers away from heat, sparks, open flame and strong oxidizing agents.
- Store closed drums with bung in up position.
- Flammable materials should be stored in a separate safety storage cabinet or room.
- Avoid breathing vapors in top of shipping container; may contain a known human carcinogen.
- Vapor space above stored liquid may be flammable/explosive unless blanketed with inert gas.
- Keep container tightly closed and properly labeled.

- Use PPE that is chemical resistant to the product and prevents skin contact.
- Fire retardant clothing is appropriate for routine occupational use.

Hygiene measures :
- Selection of appropriate personal protective equipment should be based on an evaluation of the performance characteristics of the protective equipment relative to the task(s) to be performed, conditions present, duration of use, and the hazards and/or potential hazards that may be encountered during use.
- Emergency eye wash fountains and safety showers should be available in the immediate vicinity of any potential exposure.
- Use good personal hygiene practices.
