| 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 gloves to prevent skin exposure. Clothing: Wear appropriate clothing to prevent skin exposure. | 【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】
Rapid heart rate and rapid breathing are common. Severe exposure may cause cardiovascular collapse and respiratory arrest. Headache may develop. Agitation and anxiety may develop in patients with significant respiratory compromise. Chlorine (as hypochlorite) has been teratogenic in experimental animals. Mutations were detected using sperm morphology in mouse studies. | 【Exposure limit(s)】
NIOSH REL: TWA 0.2 mg/m3 ST 0.4 mg/m3 OSHA PEL: TWA 0.2 mg/m3 IDLH 5 mg/m3 | 【Poison Class】

| Fire Fighting Measures | Back to Contents | 【Flash Point】
84 | 【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: Do NOT get water inside containers. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam. | 【Fire Potential】
This material is probably combustible. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Clean up spills immediately, using the appropriate protective equipment. Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Provide ventilation. Do not get water inside containers. |
| Stability and Reactivity | Back to Contents | 【Stability】
Stable at room temperature in closed containers under normal storage and handling conditions. | 【Incompatibilities】
Strong oxidizing agents, water. | 【Decomposition】
Hydrogen chloride, nitrogen oxides, phosgene, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, nitrogen. |
