- When mixed with air and exposed to ignition source, vapors can burn in open or explode if


- 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.

- 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.

Further information :

- Collect contaminated fire extinguishing water separately. This must not be discharged into


- Fire residues and contaminated fire extinguishing water must be disposed of in accordance with

 local regulations.

Special protective equipment for fire-fighters :

- Wear positive pressure self-contained breathing apparatus (SCBA).

- Structural firefighters protective clothing will only provide limited protection.

Accidental release measures

Environmental precautions :

- This substance is highly volatile, partially water soluble and has only a minimal tendency to

 adhere to soil particles.  

- Even small volumes can pose a threat to the environment and nearby water resources.  

- Surface spills can reach groundwater through porous soil or cracked surfaces.

- All efforts should be made to prevent any leaks or spills, and to protect water resources.  

- Where spills are possible, a comprehensive spill response plan should be developed and


- If a leak or spill reaches the groundwater, the groundwater may become contaminated.  

- If the groundwater is a source of drinking water, the associated drinking water well(s) could

 become contaminated.  

- This substance may impart an unpleasant taste and odor to water.

Methods for cleaning up :

- 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.

- Absorb or cover with dry earth, sand or other non-combustible material and transfer to


- Use clean non-sparking tools to collect absorbed material. Wipe up with absorbent material (e.g.

 cloth, fleece).

- Keep in suitable, closed containers for disposal.

Handling and storage

Handling :

Advice on safe handling :

- Keep container tightly closed when not in use.

- It is recommended that any liquid product exposed to air not be highly concentrated by

 evaporation without first assuring that no peroxide is present.

- Alternately, positive steps should be taken to reduce any accumulated peroxides to a safe level

 before concentrating the liquid.

- Use only non-sparking tools.

- Carefully vent any internal pressure before removing closure.

- Containers must be properly grounded before beginning transfer.

- Do not pressurize, cut, weld, braze, solder, drill, grind or expose containers to heat or sources of


- Do not puncture or incinerate container.

- Empty pressure vessels should be returned to the supplier

- All equipment must conform to applicable electrical code.

- Handle empty containers with care; vapor residue may be flammable/explosive.

- Isolate, vent, drain, wash and purge systems or equipment before maintenance or repair.

- Ensure adequate ventilation.

- Extinguish all ignition sources.

- Check atmosphere for explosiveness and oxygen deficiencies.

- Wear recommended personal protective equipment.

- Observe precautions pertaining to confined space entry.

- Keep away from sources of ignition - No smoking.

- Take measures to prevent the build up of electrostatic charge.

Storage :

Requirements for storage areas and containers:

- Store only in tightly closed, properly vented containers away from heat, sparks, open flame and

 strong oxidizing agents.

- Storage under nitrogen atmosphere is recommended to minimize possible formation of highly

 reactive peroxides.

- Vapor space above stored liquid may be flammable/explosive unless blanketed with inert gas.

- Store closed drums with bung in up position.

- No smoking.

- Store in cool place.

Container Advice :

Carbon Steel.

Other data :

No decomposition if stored and applied as directed.

Exposure controls / personal protection

Engineering measures :

- Provide adequate ventilation. Use process enclosures, local exhaust ventilation, or other

 engineering controls to keep airborne levels below recommended exposure limits.

- Electrical equipment should be grounded and conform to applicable electrical code.

Respiratory protection :

- In case of dusts/vapours/aerosols being formed or if the limit values like TLV are  

 exceeded:  wear respirator conforming to EN140 with type A filter or better".

Hand protection :

- Chemical-resistant protective gloves (EN 374)

- The selected protective gloves have to satisfy the standard EN 374 derived from it.

 Glove material for example, Glove (multi-layer) - PE/EVAL/PE

 (PE=Polyethylene; EVAL=Ethylene-vinyl-alcohol-copolymer); Break through time  >= 480 min.
