- Harmful: may cause lung damage if swallowed (Aspiration).
- At high doses, effects on the CNS are possible.

General advice :
- Always observe self protection methods.
- Move out of dangerous area.
- Remove contaminated shoes and clothing.
- Consult a physician.
- Show this material safety data sheet to the doctor in attendance.

Inhalation :
- Immediately seek medical attention.
- If breathing is difficult, give oxygen.
- If unconscious place in recovery position and seek medical advice.
- In the event of unconsciousness, apnea or cardiac arrest (no Pulse), apply cardiopulmonary
resuscitation.

Skin contact :

Advice to Physician :
- If inhalation of high concentrations occurs signs and symptoms may include coughing, choking, wheezing, difficulty in breathing, chest congestion, shortness of breath and/or fever. The onset of respiratory symptoms may be delayed.
- Absorption by Inhalation or Ingestion of high doses may cause CNS symptoms like headache, dizziness, fatigue, muscular, weakness, drowsiness and lack of coordination.
- In case of ingestion the stomach should be emptied by gastric lavage under qualified medical supervision.

Fire-fighting measures

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.

Specific hazards during fire fighting :
- Releases flammable vapors below normal ambient temperatures.
- Flammable vapors may be heavier than air.
- May travel long distances along the ground before igniting and flashing back to vapor source.
- When mixed with air and exposed to ignition source, vapors can burn in open or explode if
confined.
- 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
tank.
- 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
drains.
- 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
implemented.
- 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
containers.
- 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
ignition.
- 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 :
