Section 8: Exposure Controls/ Personal Protection 
Control parameters: 
Occupational exposure limits: 
Component   CAS No.   Value   Control Parameters   Basis 
Thallium   7440-28-0   TWA   0.100000 mg/m 3   USA. ACGIH Threshold Limit Values (TLV) 
Remarks: Alopecia Adopted values or notations enclosed are those for which changes are proposed in the NIC 2010
Revision or addition to the notice of intended changes (see Notice of Intended Changes   –   NIC). Danger of cutaneous
absorption. 
Exposure controls: 
Appropriate engineering controls:   Avoid contact with skin, eyes and clothing. Wash hands before breaks and
immediately after handling the product. 
Individual protection measures, such as personal protective equipment: 
Eye/face protection:   Face shield and safety glasses. Use equipment for eye protection tested and approved under
appropriate government standards such as NIOSH (US) or EN 166 (EU). 
Hand protection:   Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique 
(without touching glove’s outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after 
use in accordance with applicable laws and good laboratory practices. Wash and dry hands. 
Body protection:   Complete suit protecting against chemicals. The type of protective equipment must be selected
according to the concentration and amount of the dangerous substance at the specific workplace. 
Respiratory protection:   Where risk assessment shows air-purifying respirators are appropriate, use a full-face particle
respirator type N100 (US) or type P3 (EN 143) as a backup to engineering controls. If the respirator is the sole means
of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under
appropriate government standards such as NIOSH (US) or CEN (EU).
