EMERGENCY OVERVIEW
PHYSICAL APPEARANCE AND ODOR: Colorless liquid with a slight odor.
IMMEDIATE CONCERNS: May be harmful by inhalation. Use in well ventilated areas. Irritating to eyes. May cause skin irritation. May
cause sensitization by inhalation and skin contact. Repeated inhalation of vapour or aerosol at levels above the occupational exposure limit
could cause respiratory sensitization. A hyper-reactive response to even minimal concentrations of diisocyanates may develop in sensitized
persons. The onset of the respiratory symptoms may be delayed for several hours after exposure.
Reacts slowly with water to produce carbon dioxide which may rupture closed containers. This reaction accelerates at higher temperatures.
Do not breathe vapor or mist. Do not get on skin or clothing. Avoid contact with eyes. Use only with adequate ventilation. Keep container
tightly closed and sealed until ready for use. Wash thoroughly after handling.
POTENTIAL HEALTH EFFECTS
EYES: Causes serious eye irritation.
SKIN: May cause skin irritation. May cause an allergic skin reaction.
INGESTION: May be harmful if swallowed.
INHALATION: May be harmful if inhaled. Inhalation at levels above the occupational exposure limit could cause respiratory sensitization
and risk of serious damage to the respiratory system.
MEDICAL CONDITIONS AGGRAVATED: Pre-existing eye, skin, and respiratory conditions may be aggravated by exposure.
ROUTES OF ENTRY: Eye and skin contact, inhalation of vapors, or accidental ingestion.
SENSITIZATION: May cause allergic skin and respiratory reaction.
