| 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. | 【Respirators】

Chronic exposure may cause reproductive disorders and teratogenic effects. Vitamin D ingested in excess results in hypercalcemia, which is caused by excessive absorption of massive quantities of calcium by the intes tine and enhanced bone resorption. Causes impairment of kidneys inclu ding excessive thirst and urination, nocturia, proteinuria, and decrea sed urinary concentration ability. | 【Poison Class】

| Fire Fighting Measures | Back to Contents | 【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】
Wash area with soap and water. 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. |
| Stability and Reactivity | Back to Contents | 【Stability】
Stable under normal temperatures and pressures. Decomposes on exposure to air and light. | 【Incompatibilities】
Strong oxidizing agents, strong acids, strong bases, air, direct light. | 【Decomposition】
Carbon monoxide, carbon dioxide, acrid smoke and fumes. | 【Combustion Products】
Fire may produce irritating, corrosive and/or toxic gases. |
