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.
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
Carbon oxides
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 vapours, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapours accumulating to form explosive concentrations. Vapours can accumulate in low areas.
Prevent further leakage or spillage if safe to do so. Discharge into the environment must be avoided.
collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations (see section 13)

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Avoid contact with skin and eyes. Avoid inhalation of vapour or mist. Keep away from sources of ignition - No smoking. Take measures to prevent the build up of electrostatic charge.
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.
Keep away from sources of ignition - No smoking. Take measures to prevent the build up of electrostatic charge.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Handle in accordance with good industrial hygiene and safety practice.
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.
Tightly fitting safety goggles. Faceshield (8-inch minimum). Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
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).
