This standard applies to occupational exposures to chromium (VI) in
all forms and compounds in general industry, except: (a) Exposures
that occur in the application of pesticides regulated by the
Environmental Protection Agency or another Federal government
agency ( e.g., the treatment of wood with preservatives); (b)
Exposures to portland cement; or (c) Where the employer has
objective data demonstrating that a material containing chromium or
a specific process, operation, or activity involving chromium cannot
release dusts, fumes, or mists of chromium (VI) in concentrations at
or above 0.5 μgm/m3 as an 8-hour time-weighted average (TWA)
under any expected conditions of use.
Chromium (VI) [hexavalent chromium or Cr(VI)] means chromium

8.2 Exposure controls
Appropriate engineering controls
Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of
workday.
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).
Skin 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) respirator cartridges 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).
Control of environmental exposure
Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the
