Chemical Hygiene Plan and Laboratory Safety Manual

The Occupational Safety and Health Administration (OSHA) regulation 29 CFR 1910.1450, “Occupational Exposure to Hazardous Chemicals in Laboratories”, requires that a Chemical Hygiene Plan (CHP) be developed for each laboratory workplace to protect employees from injury due to chemical exposure in the workplace. Among other required elements, the OSHA Lab Standard specifies that the CHP must include “criteria that the employer will use to determine and implement control measures to reduce employee exposure to hazardous chemicals including engineering controls, the use of personal protective equipment and hygiene practices; particular attention shall be given to the selection of control measures for chemicals that are known to be extremely hazardous (1910.1450(e)(3)(ii)).

The Laboratory Safety Manual and Chemical Hygiene Plan [doc] is a living document developed by USC Environmental Health and Safety. Our intent is ultimately create a comprehensive document that will address all commonly encountered hazardous substances, equipment and processes in our laboratories. This document, in its present form, serves as a template that can be used by Principal Investigators and Lab Managers in developing their lab-specific Laboratory Safety Manual and Chemical Hygiene Plan. The CHP template can be made lab-specific by filling out all required information in the appendices.
