HEXAVALENT CHROMIUM AWARENESS
While The Company does not expect any exposure to Hexavalent Chromium, if the job or project that we are
working is determined to contain or potentially expose our workers, then we will work with the client to first
determine if the hazard can be engineered out or if we will need to establish a protocol using this policy to safely
perform the work. The equipment and processes that typically contain hexavalent chromium will be identified
by the work permit and or job hazard analysis systems. Procedures for elimination or minimization of exposure
will be the 1st line of defense. Special precautions will be exercised when maintenance of ventilation systems
and changing of filters is performed.
DEFINITIONS
Action Level = a concentration of airborne chromium (VI) of 2.5 micrograms per cubic meter of air (2.5 μg/m³)
calculated as an 8-hour time-weighted average (TWA)
Chromium (VI) [hexavalent chromium or Cr (VI)] means chromium with a valence of positive six, in any form
and in any compound
Emergency means any occurrence that results, or is likely to result, in an uncontrolled release of chromium
(VI). If an incidental release of chromium (VI) can be controlled at the time of release by workers in the
immediate release area, or by maintenance personnel, it is not an emergency
Worker Exposure means the exposure to airborne chromium (VI) that would occur if the worker were not using
a respirator
Regulated Area means an area, demarcated by the employer, where a worker’s exposure to airborne
concentrations of chromium (VI) exceeds, or can reasonably be expected to exceed the PEL. Access to Regulated
Area shall be limited to:
x Persons authorized by the employer
x Persons with required work duties in the regulated area
x Workers are not permitted to eat, drink, smoke, chew tobacco or gum, or apply cosmetics in the
regulated area where skin and eye contact with Chromium VI may occur
Permissible Exposure Limit (PEL). The Company shall ensure that no worker is exposed to an airborne
concentration of chromium (VI) in excess of 5 micrograms per cubic meter of air (5 μg/m³), calculated as an 8hour time-weighted average (TWA)
x Below 0.5 μg/m³ under any condition – Exempt
x Between 0.51 and 2.5 μg/m³
o Housekeeping – no dust
o Clean eating and drinking areas
x Above action level 2.5 μg/m³ for more than 30 days per year
o All of the above
o Install engineering controls
o Personal respiratory protection
