of Combustion Products: Irritating vapors generated when exposed to heat; Behavior in Fire: Not
pertinent; Ignition Temperature : No data; Electrical Hazard: Not pertinent; Burning Rate: No data.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
reactions; Stability During Transport: Stable; Neutralizing Agents forAcih and Caustics: Not pertinent;
Polymerization: Heat, peroxides, and caustics cause polymerization, however the reaction is slow and
generally considered nonhazardous; Inhibitor of Polymerization: 50 ppm of Hydroquinone Monomethyl
Ether.

Health Hazards Information - Recommended Personal Protective Equipment: Goggles or face shield;
rubber gloves; Symptoms Following Exposure: Inhalation causes some irritation of nose and throat.
Contact with liquid irritates eyes and causes mild irritation of skin; stains skin yellow. (No information
available on symptoms of ingestion.); General Treatment for Exposure: INHALATION: remove from
exposure. EYES or SKIN: flood with water for 15 min. INGESTION: no information on treatment;
Toxicity by Inhalation (Threshold Limit Value) : Data not available; Short-Tern Inhalation Limits: Data
not available; Toxicity by Ingestion: Grade 2; oral rat LD,, = 2,020 mg/kg; Late Toxicity: Data not
available; Vapor (Gas) Irritant Characteristics: Vapors cause a slight smarting of the eyes or
respiratory system if present in high concentrations. The effect is temporary; Liquid or Solid Irritant
Characteristics: Minimum hazard. If spilled on clothing and allowed to remain, may cause smarting
and reddening of the skin, Odor Threshold: Data not available.
