Acetic Anhydride - Risk Assessment Document

This risk assessment document is aimed at a technical audience and provides the scientific information which underpins the setting of an occupational exposure limit (OEL) for a specific substance, in this case acetic anhydride.

In the UK, OELs are set under the Control of Substances Hazardous to Health Regulations (COSHH) 1999.

Two types of exposure limits are used: the maximum exposure limit (MEL) and the occupational exposure standard(OES).

A description of the criteria used to determine which type of limit is applicable is given in the HSE publications "EH40, Occupational Exposure Limits" and "EH64, Summary Criteria for Occupational Exposure Limits".
