· Structural firefighters' protective clothing provides thermal protection but only limited chemical protection.
EVACUATION
Immediate precautionary measure
· Isolate spill or leak area for at least 25 meters (75 feet) in all directions.
Large Spill
· Consider initial downwind evacuation for at least 100 meters (330 feet).

· If it can be done safely, move undamaged containers away from the area around the fire.
Fire Involving Metal Pigments or Pastes (e.g. "Aluminum Paste")

Fire Involving Tanks or Car/Trailer Loads
· Cool containers with flooding quantities of water until well after fire is out.
· For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn.
· Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
· ALWAYS stay away from tanks engulfed in fire.
SPILL OR LEAK
· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.
· Do not touch or walk through spilled material.
Small Dry Spill
· With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area.
Large Spill
· Wet down with water and dike for later disposal.
· Prevent entry into waterways, sewers, basements or confined areas.
FIRST AID
· Call 911 or emergency medical service.
· Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.
· Move victim to fresh air if it can be done safely.
· Give artificial respiration if victim is not breathing.
· Administer oxygen if breathing is difficult.
· Remove and isolate contaminated clothing and shoes.
· In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
· Removal of solidified molten material from skin requires medical assistance.
· Keep victim calm and warm.
