5. Fire Fighting Measures
Flammability of the Product: Flammable.
Suitable extinguishing media: Carbon dioxide (CO2). Extinguishing powder. Water spray (fog). Alcohol resistant foam.
Auto-Ignition Temperature: 520.
Flash Points: 50C
Products of Combustion: Carbon dioxide, Carbon monoxide, Toxic fumes.
Fire: Inflammable.
Explosion: Cool containers with flooding quantities of water until well after fire is out. Prevent fire extinguishing water from contaminating surface water or the ground water system. Explosive in presence of heat.
Fire Extinguishing Media: Use water spray or fog. Flammable liquid and vapor. Vapors are heavier than air and may travel to a source of ignition and flash back. Vapors can spread along the ground and collect in low or confined areas. Never direct a water jet in the container to prevent any splashing of the product which could cause spreading of the fire. Cool containing vessels with water jet in order to prevent pressure build-up, auto-ignition or explosion.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes. Keep away from sources of ignition. Prevent fire fighting water from entering surface water or groundwater.
6. Accidental Release Measures
Personal precautions, protective equipment, and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Do not approach facing the wind.
Environmental precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment Cleanup procedures and Storage:
Small Spill: Avoid mist formation. Avoid breathing mist. Ensure adequate ventilation. Use appropriate tools to put the spilled solid in a convenient waste disposal container.
Large Spill: Do not inhale dust, vapors, mist, or gas. Avoid dust formation. Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite). Use a shovel to put the material into a convenient waste disposal container.
Large liquid spillages should be contained by use of sand or another inert material. Dyke to collect large liquid spills. Pump up the product into a spare container suitably labeled. The spillage should be transferred to a suitable container and recovered or disposed of in accordance with local regulations. Because of the danger of spontaneous combustion, any combustible material, such as cloth, used for cleaning spillages, should be saturated with water, and disposed of promptly, preferably by incineration.
7. Handling and Storage
Precautions for safe handling: Do not ingest. Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. Wash thoroughly after handling. Do not drink, eat, or smoke while handling. Avoid contact with skin, eyes, and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.).
Conditions for safe storage, including any incompatibilities: Store in cool, dry, and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like strong oxidizing agents, strong reducing agents, strong acids, strong bases.
