| First Aid Measures | Back to Contents | 【Ingestion】
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately. | 【Ingestion】
Seek medical assistance. | 【Inhalation】
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. | 【Inhalation】
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. | 【Inhalation】
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Effects of contact or inhalation may be delayed. | 【Skin】
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Remove contaminated clothing and shoes. | 【Skin】
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. | 【Skin】
Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. | 【Eyes】
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. | 【Eyes】
See Skin. | 【Eyes】
Immediately flush with running water for at least 20 minutes. |
| Handling and Storage | Back to Contents | 【Storage】
Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances. | 【Storage】
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage. | 【Handling】
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. | 【Handling】
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood. |

| Exposure Controls/Personal Protection | Back to Contents | 【Personal Protection】
Eyes: Wear chemical goggles. 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 minimize contact with skin. Wear appropriate protective clothing to prevent skin exposure. | 【Personal Protection】
Wear appropriate protective gloves, clothing and goggles. | 【Respirators】
Wear positive pressure self-contained breathing apparatus (SCBA). | 【Respirators】
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use. 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】
The toxological properties of this substance have not been fully investigated. | 【Exposure limit(s)】
10 µg/m3 PEL |
| Fire Fighting Measures | Back to Contents | 【Fire Fighting】
Small Fires: Dry chemical, carbon dioxide or water spray. Large Fires: Water spray, fog or regular foam. | 【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. | 【Fire Potential】
Combustible material: may burn but does not ignite readily. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation. | 【Small spills/leaks】
Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Cover with plastic sheet to prevent spreading. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. |
