EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of dust, through the skin and by ingestion. Effects of short-term exposure	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. Effects of long-term or repeated exposure The substance may have effects on the bladder. This may result in inflammation and tissue lesions. This substance is carcinogenic to humans. See Notes.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of dust, through the skin and by ingestion.

Effects of short-term exposure

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

Effects of long-term or repeated exposure
The substance may have effects on the bladder. This may result in inflammation and tissue lesions. This substance is carcinogenic to humans. See Notes.

OCCUPATIONAL EXPOSURE LIMITS
TLV: (skin); A1 (confirmed human carcinogen). MAK: skin absorption (H); carcinogen category: 1; germ cell mutagen group: 3A

ENVIRONMENT
Environmental effects from the substance have not been investigated adequately.

NOTES
Depending on the degree of exposure, periodic medical examination is suggested. Special attention should be given to urine sediment and cytology. Special attention should be given to blood in urine. Do NOT take working clothes home.
