Specification

1、Fire Fighting Measures
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or chemical foam.
2、Handling and Storage
Handling: Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Take precautionary measures against static discharges. Use only in a chemical fume hood.
Storage: Store in a cool, dry place. Do not store in direct sunlight. Store in a tightly closed container.
