Hazards and Protection.
Keep tightly closed in a cool place in a tightly closed container.
Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data sheet must be observed.
Wear appropriate protective gloves, clothing and goggles.
If overexposure has been determined or documented, a NIOSH/MSHA jointly approved air supplied respirator is advised in absence of proper environmental control. OSHA regulations also permit other NIOSH/MSHA respirators under specified conditions.
Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Add soda ash (Na2CO3). Adjust pH to neutral (pH=7). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
Reacts as acid to neutralize bases.
Ammonia, ammonium chloride fumes, hydrogen chloride, zinc oxide, zinc chloride fumes.
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.)
May burn but does not ignite readily.
Some may burn but none ignite readily. May polymerize explosively when heated or involved in a fire. Containers may explode when heated. Some may be transported hot.
Fire may produce irritating, corrosive and/or toxic gases.
The toxological properties of this substance have not been fully investigated.
Swallowing this material may be harmful or fatal. Symptoms may include severe stomach and intestinal irritation (nausea, vomiting, diarrhea), abdominal pain, and vomiting of blood. Swallowing this material may cause burns and destroy tissue in the mouth, throat, and digestive tract. Low blood pressure and shock may occur as a result of severe tissue injury.
Inhalation of material may be harmful.
Contact may cause burns.
Seek medical assistance.
Remove from exposure; begin artificial respiration if breathing has ceased.
Flush with water.
Flush with water for at least 15 min.
