a. Chemical manipulations are carried out on a “laboratory scale.”
b. The procedures involved are not part of a production process, nor in any way simulate a production process; and
c. “Protective laboratory practices and equipment” are available and in common use to minimize the potential for employee exposure to hazardous chemicals.
*Laboratory scale means work with substances in which the containers used for reactions, transfers, and other handling of substances are designed to be easily and safely manipulated by one person.
The CHP does not apply to:
a. Uses of hazardous chemicals that do not meet the definition of laboratory use.
b. Laboratory uses of hazardous chemicals that provide no potential for employee exposure. Examples of such conditions might include:
1. Procedures using chemically-impregnated test media such as Dip-and-Read tests where a reagent strip is dipped into the specimen to be tested and the results are interpreted by comparing the color reaction to a color chart supplied by the manufacturer of the test strip, and
2. Commercially prepared kits such as those used in performing pregnancy tests in which all of the reagents needed to conduct the test are contained in the kit.
Laboratory uses of chemicals not covered by the CHP are subject to the full provisions of the OSHA Hazard Communication Standard. Contact the Chemical Hygiene Officer in the Office of Research Safety for additional information.
