First Aid Measures
Emergency procedures for chemical exposure incidents
If breathed in, move person into fresh air. If not breathing give artificial respiration. Consult a physician.
Wash off with soap and plenty of water. Consult a physician.
Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.
Do NOT induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.
Immediate Medical Attention
Consult a physician.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
For small (incipient) fires, use media such as "alcohol" foam, dry chemical, or carbon dioxide. For large fires, apply water from as far as possible. Use very large quantities (flooding) of water applied as a mist or spray; solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water.

Firefighter Protection
Wear self contained breathing apparatus for fire fighting if necessary.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Use personal protective equipment. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Beware of vapours accumulating to form explosive concentrations. Vapours can accumulate in low areas.
Do not let product enter drains.
collect with non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite) and place in container for disposal according to local / national regulations (see section 13). Keep in suitable, closed containers for disposal.

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Avoid inhalation of vapour or mist. Keep away from sources of ignition - No smoking. Take measures to prevent the build up of electrostatic charge.
Keep container tightly closed in a dry and well-ventilated place. Store in cool place.

Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Handle with gloves.
Face shield and safety glasses
Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
Choose body protection according to the amount and concentration of the dangerous substance at the work place.
