- HAZCHEM
- Not available.
Special protective equipment and precautions for fire fighters
As in any fire, 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.
6. Accidental Release Measures
- Personal precautions, protective equipment and emergency procedures
- Use proper PPE as indicated in Section 8.
- Environmental precautions
- Avoid runoff into storm sewers and ditches which lead to waterways.
- Do not let product enter drains.
- Prevent further leakage or spill is safe to do so.
- Methods and materials for containment and clean up
- Clean up spills immediately, observing precautions in the Protective Equipment section. Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Provide ventilation.
7. Handling and Storage
- Precautions for safe handling
- Wash thoroughly after handling. Wash hands before eating. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
- Conditions for safe storage
- Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
8. Exposure Controls / Personal Protection
Exposure Standards
- Engineering controls
- Eyebath/eyewash & Safety shower.
- Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels.
Personal protective equipment
- Eye and face protection
- Safety glasses.
- Skin protection
- The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it. Handle with gloves. 0.11mm thick nitrile.
- Body protection
- Choose body protection according to the amount and concentration of the dangerous substance at the work place.
- Hygiene measures:
- Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately after handling the product.
- Respiratory protection
- Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type N99 (US) or type P2 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN.
