【UN (DOT)】1993

Exposure Controls/Personal Protection
【Personal Protection】Compatible chemical-resistant gloves. Chemical safety ggles. Protective clothing.
【Respirators】Use respirators and components tested and approved under appropriate vernment 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.

Fire Fighting Measures
【Fire Fighting】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. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.
【Fire Potential】Combustible liquid.

Accidental Release Measures
【Small spills/leaks】Cover with dry-lime, sand, or soda ash. Place in covered containers using non-sparking tools and transport outdoors. Ventilate area and wash spill site after material pickup is complete.

Stability and Reactivity
【Stability】Stable if stored as directed.
【Incompatibilities】Strong oxidizing agents.
【Decomposition】Carbon monoxide, Carbon dioxide, Sulfur oxides, Hydrogen bromide gas.
