Hazards and Protection.
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.
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.
Wear appropriate protective gloves, clothing and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
ELIMINATE all ignition sources and combustible materials. Do not touch spilled material. Stop leak if you can do it without risk. Take up with inert, damp, noncombustible material using clean non-sparking tools and place into loosely covered plastic containers for later disposal. For large spills, contact specialist for clean-up or disposal instructions.
The temperature of the substance must be maintained at or below the Control Temperature at all times. Small Fires: Water spray or fog is preferred; if water not available use dry chemical, carbon dioxide or regular foam. Large Fires: Flood fire area with water from a distance. Use water spray or fog; do not use straight streams.
May explode from heat, contamination or loss of temperature control. Particularly sensitive to temperature rises.
May ignite combustibles (wood, paper, oil, clothing, etc.). May ignite spontaneously if exposed to air. May be ignited by heat, sparks or flames.
Fire may produce irritating, corrosive and/or toxic gases.
May cause severe injury or burns.
Seek medical assistance.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes. Remove material from skin immediately. Immediately flush with running water for at least 20 minutes.
