Hazards and Protection.
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
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.
Protection
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
Respirators
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers.
Stability
No data.
Incompatibilities
Flammable and/or toxic gases are generated by the combination with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents Can react with air to give first peroxo acids, and ultimately carboxylic acids.

Fire.
Fire fighting
Solid streams of water may spread fire. Use water in flooding quantities as fog. Use dry chemical, graphite, or dry earth.
Fire potential
Flammable/combustible material.
Hazards
May be ignited by friction, heat, sparks or flames. Some may burn rapidly with flare burning effect. Powders, dusts, shavings, borings, turnings or cuttings may explode or burn with explosive violence. Substance may be transported in a molten form. May re-ignite after fire is extinguished.
