EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body through the skin and by ingestion. Effects of short-term exposure The substance is irritating to the eyes, skin and possibly the respiratory tract. The substance may cause effects on the gastrointestinal tract, central nervous system and peripheral nervous system. Exposure could cause hair loss. Ingestion of large amounts could cause effects on the cardiovascular system, kidneys and liver. Ingestion of large amounts could cause death. The effects may be delayed. Medical observation is indicated. See Notes.	Inhalation risk A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. Effects of long-term or repeated exposure The substance may have effects on the nervous system. May cause hair loss.

OCCUPATIONAL EXPOSURE LIMITS
TLV: (as Tl, inhalable fraction): 0.02 mg/m³, as TWA; (skin)

ENVIRONMENT
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.

NOTES
The symptoms of neurological disorders do not become manifest until after a few days. Depending on the degree of exposure, periodic medical examination is suggested. Do NOT take working clothes home. See ICSCs 0077 and 1221.
