HYDROXYPROPYL METHACRYLATE 211

Toxicity: Data not available; Vapor (Gas) Irritant Characteristics: Vapors are moderately irritating such
that personnel will not usually tolerate moderate or high concentrations; Liquid or Solid Irritant
Characteristics: This chemical is a severe skin irritant. Direct contact with this chemical causes second-
and third-degree chemical burns - even short contact, and is very injurious to the eyes; Odor Threshold

Extinguishing Agents: Dry chemical, alcohol foam, or carbon dioxide; Fire Extinguishing Agents Not
To Be Used: Water may be ineffective; Special Hazards of Combustion Products: No data; Behavior
in Fire: No data; Ignition Temperature : No data; Electrical Hazard: No data; Burning Rate: No data.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
reactions; Stability During Transport: Stable; Neutralizing Agents forAcids and Caustics: Not pertinent;
Polymerization: Polymerization may occur. Avoid exposure to high temperatures, ultraviolet light, and
free-radical catalysts; Inhibitor of Polymerization: 200 ppm Hydroquinone.

Health Hazards Information - Recommended Personal Protective Equipment: Face shield; rubber
gloves; Symptoms Following Exposure: Inhalation causes coughing and irritation of nose and throat;
lung injury may occur. Ingestion causes irritation and burning of mouth and stomach. Vapor contact
with eyes causes irritation. Liquid causes severe eye burns and skin irritation; General Treatment for
Exposure: INHALATION: immediately remove victim to fresh air; if required, start artificial
respiration and call a doctor. INGESTION: force milk or water at once; get medical attention. EYES:
flush with water for at least 15 min.; get medical attention if irritation persist. SKIN: flush with copious
amounts of water; seek immediate medical attention for chemical burns; Toxicity by Inhalation: No
data; Short-Term Inhalation Limits: No data; Toxicity by Ingestion: Grade 1; LD,, 5-15 glkg (mouse);
Late Toxicity: No data; Vapor (Gus) Irritant Characteristics: No data; Liquid or Solid Irritant
Characteristics: Data not available; Odor Threshold: No data.
Fire Hazards - Flash Point (deg. F): 250 OC; Flammable Limits in Air: No data; Fire Extinguishing

be ineffective; Special Hazards of Combustion Products: No data; Behavior in Fire: Can polymerize
when hot and burst containers; Ignition Temperature: No data; Electrical Hazard: No data; Burning
Rate: No data.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
reactions; Stability During Transport: Stable; Neutralizing Agents forAcids and Caustics: Not pertinent;
