water spray (fog). |
| Fire fighting procedure |
Cool containers with water spray.
Fire fighters should wear full protective clothing and self-contained
breathing apparatus
(SCBA) in positive pressure mode. |
Unusual fire and explosion
hazards |

MEASURES)
| Personal precautions |
Wear self-contained breathing apparatus,
full PVC clothing, PVC gloves and boots. |
| After spillage / leakage |
Sweep up, place in a bag and hold
for waste disposal or possible re-use.
Avoid raising dust. |
7. HANDLING AND STORAGE
| Handling |
Keep containers tightly closed.
Avoid producing or diffusing dust into the air. |
| Storage |
