HEALTH HAZARD DATA
This substance is a potential carcinogen and should therefore be handled with extreme care. It is toxic and an irritant. Acute exposure to the skin may cause irritation. Prolonged contact may cause dermatitis. Acute exposure to the eyes may cause redness and irritation. Prolonged exposure may cause conjunctivitis.

DISPOSAL
SPILLS:
A gas leak keep the concentration of the gas below the explosive mixture range by forced ventilation. Remove the tank to an open area and allow dissipation to the atmosphere. Attempt to cap the valve outlet and return the tank to the supplier.
A liquid absorb on paper. Evaporate in an iron pan in a flame proof fume hood then burn the paper.
A solid sweep on to paper and place in an iron pan in a fume hood. Burn the paper and compound.
PACKAGE LOTS:
A gas pipe the gas into an incinerator or lower into a pit and allow to burn.
A liquid atomise into an incinerator. Combustion may be improved by mixing with a more flammable solvent.
A solid make up packages in paper or other flammable material. Burn in the incinerator. Or the solid may be dissolved in a flammable solvent and sprayed into a fire chamber.
