- Never give anything by mouth to an unconscious person.
Advice to Physician :
- Treat symptomatically.
- Treatment of overexposure should be directed at the control of symptoms and the clinical condition of
the patient.
- Inhalation of very high concentrations may cause asphyxia, anesthesia, CNS depression (primarily
fatigue, dizziness and loss of concentration, with collapse, coma and death in cases of severe
overexposure), and possible cardiac sensitization.
- Epinephrine and other sympathomimetic drugs may initiate cardiac arrhythmias (irregular beating) in
persons exposed to this material.
- Aspiration may cause pulmonary edema and pneumonitis.
- Do NOT induce vomiting.
- In case of ingestion, the stomach should be emptied by gastric lavage under qualified medical
supervision.
Fire-fighting measures
Suitable extinguishing media:
Small fires :
- Use dry chemicals, CO2, or foam
Large fires ;
- Use water spray, water fog or foam.
Unsuitable extinguishing media
- Do not use a solid water stream as it may scatter and spread fire.
- WARNING - Water may be ineffective unless used under favorable conditions by experienced fire
fighters trained in fighting all types of flammable liquid fires. Water can be used to cool and protect
exposed material.
Specific hazards during fire-fighting :
- Releases flammable vapors below normal ambient temperatures.
- When mixed with air and exposed to ignition source, vapors can burn in open or explode if confined.
- Flammable vapors may be heavier than air.
- 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.
- Heat may build enough pressure to rupture closed containers/spreading fire/increasing risk of
burns/injuries.
- Move containers from fire area if you can do it without risk.
- 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.
- 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 positive pressure self-contained breathing apparatus (SCBA).
- Structural firefighters protective clothing will only provide limited protection.

- All equipment used when handling this product must be grounded.
- Do not touch or walk through spilled material.
- Water spray may reduce vapor; but may not prevent ignition in closed spaces.
- Contain/collect rapidly to minimize dispersion.
- On water, material is sparingly soluble.
- On water, contain/minimize dispersion/collect.
- Impound/recover large land spill.
- Soak up small spills with inert solids.
- Prevent flow to sewer/public waters.
- Disperse residue to reduce aquatic harm.
- Notify fire and environmental authorities.
Handling and storage
Handling :
Advice on safe handling :
- Extinguish all ignition sources.
- Use only non-sparking tools.
- Keep container tightly closed when not in use.
- All electrical equipment should be grounded and conform to applicable electric codes and regulatory
requirements.
- Containers must be properly grounded before beginning transfer.
- Carefully vent any internal pressure before removing closure.
- Isolate, 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.
- Wear recommended personal protective equipment.
- Handle empty containers with care; vapor/residue may be flammable.
Fire-fighting class :
- Highly Flammable
Storage :
Requirements for storage areas and containers :
- Store closed drums with bung in up position.
- Store only in tightly closed, properly vented containers away from heat, sparks, open flame and strong
oxidizing agents.
