First Aid Measures

Ingestion

If swallowed, wash out mouth with water provided person is conscious. Call a physician.

Inhalation

If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen.

Skin

Harmful if swallowed.

Inhalation

Material may be irritating to mucous membranes and upper respiratory tract. May be harmful if inhaled.

Skin

May cause skin irritation. May be harmful if absorbed through the skin.

Emits toxic fumes under fire conditions.

Exposure Controls/Personal Protection

Personal Protection

Compatible chemical-resistant gloves. Chemical safety goggles. Protective clothing.

Respirators

Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (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.
