Spec@ Gravity: Not pertinent; Ratio of Specific Heats of Vapor (Gas): Not pertinent; Latent Heat of
Vaporization: Not pertinent; Heat of Combustion: Not pertinent; Heat ofDecomposition: Not pertinent.
Health Hazards Information -Recommended Personal Protective Equipment: Self-contained breathing
apparatus, chemical goggles, protective clothing, synthetic rubber or plastic gloves; Symptoms
Following Exposure: INHALATION vapors are irritating and will cause coughq, chest pain, MUS=,
and vomiting. INGESTION: causes nausea, vomiting, abdominal pain, and collapse. Contact with skin
and eyes causes severe irritation; General Treatment for Exposure: INHALATION: remove victim to
fresh air; give oxygen if breathing is difficult; call a physician. INGESTION: induce vomiting at once
and repeat until vomit is clear; then give milk or raw egg and call a physician. SKIN OR EYES: flush
immediately with plenty of water for at least 15 min.; remove contaminated clothing, call a physician
for eyes; Toxicity by Inhalation (Threshold Limit Value): 2 ppm; Short-Term Inhalation Limits: 5 ppm
for 5 min., 3 ppm for 60 min. (tentative); Toxicity by Ingestion: (Formaldehyde solution) Grade 2, LD,,
0.5 to 5 glkg; Lute Toxicity: None; Vapor (Gas) Irritant Characteristics: Vapor is moderately irritating
such that personnel with not usually tolerate moderate or high concentrations; Liquid or Solid Irritant
Characteristics: Causes smarting of the skin and fust-degree burns on short exposure. May cause
secondary burns on long exposure; Odor Threshold 0.8 ppm.
Fire Hazards - Flash Point (deg. F): 182 CC (based on solution of 37 $6 formaldehyde and Methanol
free), 122 CC (based on solution with 15 96 Methanol); Flammable Limits in Air (56): 7.0 - 73; Fire
Extinguishing Agents: Water, dry chemical, carbon dioxide, or alcohol foam; Fire Extinguishing Agents
Not To Be Used: No data or recommendations found; Special Hazards of Combustion Products: Toxic
vapors form; Behavior in Fire: Not pertinent; Ignition Temperature (deg. F): 806; Electrical Hazard:
Not pertinent; Burning Rate: Not pertinent.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
reactions; Stability During Transport: Stable; Neutralizing Agents for Aciris and Caustics: Not pertinent;
Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Health Hazards Information - Recommended Personal Protective Equipment: Dust mask, gloves,
safety glasses, dust cap; Symptoms Following Exposure: Inhalation of dust may cause respiratory
irritation. Compound is non-toxic when ingested. Prolonged contact with eyes or skin may cause
irritation; General Treatment for Exposure: INHALATION: move to fresh air. EYES: flush with
water; get medical attention if irritation persists. SKIN: flush with water; Toxicity by Inhalation

by Ingestion: Data not available; Late Toxicity : Data not available; Vapor (Gas) Irritant Characteristics:
Data not available; Liquid or Solid Im'tant characteristics: Data not available; Odor Threshold:
Odorless.
Fire Hazards - Flash Point: Not pertinent. This is a combustible solid which can present a dust
explosion problem; Flammable Limits in Air (a): Not pertinent; Fire Extinguishing Agents: Water
spray, dry chemical, foam, or carbon dioxide; Fire Extinguishing Agents Not To Be Used: Not
pertinent; Special Hazards of Combustion Products: Irritating fumes of maleic anhydride may form in
fires; Behavior in Fire: Dust presents significant explosion hazard. Dust should be knocked down with
water fog when fighting fires; Ignition Temperature (deg. F): 1,364 (powder); Electrical Hazard :Not
pertinent; Burning Rate: Not pertinent.
