HEALTH |
*
Inhalation of vapors or contact with substance will result in contamination and potential
harmful effects. * Fire will produce irritating, corrosive and/or toxic gases. |
FIRE
OR EXPLOSION |
*
Non-combustible, substance itself does not burn but may react upon heating to produce
corrosive and/or toxic fumes. * Runoff may pollute waterways. |
PUBLIC

CALL Emergency Response Telephone Number on Shipping Paper first. If Shipping Paper not
available or no answer, refer to appropriate telephone number listed on the inside back
cover. * Isolate spill or leak area immediately for at least 10 to 25 meters (30 to 80
