HEALTH HAZARD DATA

Routes of Entry: Inhalation, skin, ingestion.

Hazards: Irritant. Prolonged or repeated exposure to skin may cause sensitivity.

EMERGENCY AND FIRST AID

Skin: Wash affected area with copious amounts of water.

Eye: Flush eyes with water for at least 15 minutes.

Inhalation: Remove to fresh air. Give oxygen or artificial respiration if needed.

Ingestion: Drink 1 or 2 glasses of water. Induce vomiting. Call physician.

REACTIVITY DATA

Stability: Stable.

Conditions to Avoid: Elevated temperatures, free radical initiators, and/or ultraviolet light.

Incompatibility: Free radical initiators, oxidizing and reducing agents.

Hazardous Polymerization: May occur.

SPILL, DISPOSAL AND STORAGE INFORMATION

Spill: Absorb with inert material, collect in closed containers and dispose as recommended. Avoid skin contact.

Disposal: Incineration according to federal, state and local regulations.

Storage: Store below 85E F in well ventilated area, away from direct sunlight, initiators, oxidizing and/or reducing agents. Don’t fill containers completely. Bulk storage tanks should be kept oxygenated to activate polymerization inhibitors.

PROTECTIVE EQUIPMENT AND CONTROL MEASURES

Respiratory: OSHA/MSHA approved respirator.

Ventilation: Mechanical ventilation recommended.

Gloves: Impervious gloves (e.g. nitrile, etc.) recommended.
