Safe handling
PRECAUTIONS FOR "CARCINOGENS":... dispensers of liq detergent /should be available./... Safety pipettes should be used for all pipetting.... In animal laboratory, personnel should... wear protective suits (preferably disposable, one-piece & close-fitting at ankles & wrists), gloves, hair covering & overshoes.... In chemical laboratory, gloves & gowns should always be worn... however, gloves should not be assumed to provide full protection. Carefully fitted masks or respirators may be necessary when working with particulates or gases, & disposable plastic aprons might provide addnl protection.... gowns... /should be/ of distinctive color, this is a reminder that they are not to be worn outside the laboratory. /Chemical Carcinogens/
Storage
PRECAUTIONS FOR "CARCINOGENS": Storage site should be as close as practicable to lab in which carcinogens are to be used, so that only small quantities required for... expt need to be carried. Carcinogens should be kept in only one section of cupboard, an explosion-proof refrigerator or freezer (depending on chemicophysical properties...) that bears appropriate label. An inventory... should be kept, showing quantity of carcinogen & date it was acquired... Facilities for dispensing... should be contiguous to storage area. /Chemical Carcinogens/
Disposal
PRECAUTIONS FOR "CARCINOGENS": There is no universal method of disposal that has been proved satisfactory for all carcinogenic compounds & specific methods of chem destruction... published have not been tested on all kinds of carcinogen-containing waste.... summary of avail methods & recommendations... /given/ must be treated as guide only. /Chemical Carcinogens/ PRECAUTIONS FOR "CARCINOGENS":... Incineration may be only feasible method for disposal of contaminated laboratory waste from biological expt. However, not all incinerators are suitable for this purpose. The most efficient type... is probably the gas-fired type, in which a first-stage combustion with a less than stoichiometric air:fuel ratio is followed by a second stage with excess air.
Exposure limits and toxicity
Occupational exposure limits and toxicity data
For information on chemical warfare blister agents see the ERG Criminal or Terrorist Use of CBR Agents. Toxic doses as low as 400 mg/kg have been reported in humans. Blood clots may occur at site of intravenous injection and tissue damage if outside vein. Powerful vesicant (causes blisters) when it contacts skin, mucous membranes, or eyes. Delayed toxicity -- missed menstrual periods, alopecia (hair loss), hearing loss, tinnitus (ringing in ears), jaundice, impaired spermatogenesis and germinal aplasia, swelling, and hypersensitivity. May damage fetus in pregnant women.
