Health Hazards Information - Recommended Personal Protective Equipment: Dust respirator,
chemical goggles, rubber gloves; Symptoms Following Exposure: Inhalation irritates respiratory system
and causes sneezing. Contact with liquid causes eye irritation, irritation of skin, and mucous
membranes. At high temperatures and during sun exposure, damage to the cornea, skin and mucous
membranes may occur following the liberation of acridine vapor; General Treatment for Exposure:
INHALATION: Remove victim to fresh air; if breathing has stopped, give artificial respiration; if
breathing is difficult, give oxygen. EYES: wash with copious amounts of water for 20 minutes and seek
immediate medical attention. SKIN: wash with large amounts of water for 20 min.; Toxicity by
Inhalation (Threshold Limit Value): No data; Short-Tern Exposure Limits: No data; Toxicity by
Ingestion: oral rat LD,, 2,000 mglkg; Late Toxicity: No data; Vapor (Gas) Im'tant Characteristics: No
data; Liquid or Solid Irritant Characteristics: No data; Odor Threshold: No data.

pertinent; Fire Extinguishing Agents: Water, foam, monoammonium phosphate, dry chemical; Fire
Extinguishing Agents Not To Be Used Carbon dioxide and other dry chemicals may not be effective;
Special Hazards of Combustion Products: Toxic oxides of nitrogen may form in fire; Behavior in Fire:
Sublimes before melting; Ignition Temperature: Data not available; Electrical Hazard Not pertinent;
Burning Rate: Not pertinent.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: Data
not available; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not
pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Heat of Combustion: -12500, -6950, -290; Heat OfDecomposition: Not pertinent.
Health Hazards Information -Recommended Personal Protective Equipment: Chemical safety goggles
and full face shield, self-contained breathing apparatus (SCBA), positive pressure hose mask, airline
mask; rubber safety shoes, chemical protective clothing; Symptoms Following Exposure: Inhalation
causes irritation of nose and throat, a feeling of pressure in the chest, and shortness of breath. Nausea
