EMERGENCY OVERVIEW
PHYSICAL APPEARANCE AND ODOR: Brown liquid with a slight musty odor.
IMMEDIATE CONCERNS: Harmful by inhalation. Use in well ventilated areas. Irritating to eyes, skin, and respiratory system. May cause
sensitization by inhalation and skin contact. This product is a respiratory irritant and potential respiratory sensitizer. 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: Causes skin irritation. May cause an allergic skin reaction.
INGESTION: Harmful if swallowed.
INHALATION: 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.
TARGET ORGANS: Contains material which causes damage to the following organs: upper respiratory tract.
SENSITIZATION: May cause allergic skin and respiratory reaction.
