| Exposure Controls/Personal Protection | Back to Contents | 【Personal Protection】
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure. | 【Personal Protection】
Wear appropriate government approved respirator, chemical-resistant gloves, safety goggles, other protective clothing. Faceshield (8-inch minimum). | 【Respirators】
Wear positive pressure self-contained breathing apparatus (SCBA). | 【Respirators】
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary. | 【Exposure Effects】
Corrosive. Causes burns. Harmful by inhalation, in contact with skin and if swallowed. |
| Fire Fighting Measures | Back to Contents | 【Flash Point】
192 | 【Fire Fighting】
Extinguish using Dry chemical powder. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes. | 【Fire Fighting】
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam. | 【Fire Potential】
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Clean up spills immediately, using the appropriate protective equipment. Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Provide ventilation. | 【Small spills/leaks】
Cover with dry lime or soda ash, pick up, keep in a closed container, and hold for waste disposal. Avoid raising dust. Ventilate area and wash spill site after material pickup is complete. |
| Stability and Reactivity | Back to Contents | 【Incompatibilities】
Acids. | 【Incompatibilities】
Oxidizing agents. | 【Stability】
Stable under normal temperatures and pressures. | 【Decomposition】
Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide. | 【Decomposition】
Hydrogen bromide gas. | 【Combustion Products】
Fire may produce irritating, corrosive and/or toxic gases. |
