Hazardous Chemical Information System (HCIS)

Benzene

A revised exposure standard was declared by NOHSC in April 2003.

No standard should be applied without reference to Guidance on the interpretation of Workplace exposure standards for airborne contaminants.

Benzene was the subject of a Priority Existing Chemical (PEC) assessment by the National Industrial Chemicals Notification and Assessment Scheme (NICNAS) in 2001. The PEC assessment forms the main scientific documentation that supports the amendment to the National Exposure Standard.
