First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

If breathed in, move person into fresh air. If not breathing give artificial respiration. Consult a physician.

Skin contact

Wash off with soap and plenty of water. Consult a physician.

Eye contact

Flush eyes with water as a precaution.

Ingestion

Do NOT induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

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.

Unsuitable media

solid streams of water may be ineffective

Instructions

Cool all affected containers with flooding quantities of water.

Firefighter Protection

Wear self contained breathing apparatus for fire fighting if necessary.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Emergency procedures

Avoid breathing vapors, 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.

Environmental

Prevent further leakage or spillage if safe to do so. Do not let product enter drains.

Cleanup methods

Contain spillage, and then 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).

Materials: sand, earth, diatomaceous earth, vermiculite

07

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Avoid inhalation of vapour or mist. Keep away from sources of ignition - No smoking. Take measures to prevent the build up of electrostatic charge.

Storage

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. Store in cool place. Contents under pressure.

Fire prevention

Keep away from sources of ignition - No smoking. Take measures to prevent the build up of electrostatic charge.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Hands

For prolonged or repeated contact use protective gloves.

Eyes

Face shield and safety glasses

Respiratory

Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type AXBEK (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).

Skin/Body

Choose body protection according to the amount and concentration of the dangerous substance at the work place.
