4. Criteria for Determination & Implementation of Control Measures

The Laboratory Standard states that the CHP “.... shall include criteria that the employer will use to determine and implement control measures to reduce employee exposure to hazardous chemicals ....." Hazard controls are generally classified into three broad groups: engineering controls, administrative procedures and personal protective equipment. Guidance on control measures are delineated here.

A. General

  • Lab supervisors shall determine and implement appropriate control measures and preferably incorporate them into their lab’s individual SOPs
  • Environmental Health & Safety shall be responsible for assisting the above in determining these control measures upon request. EH&S may do periodic evaluations of control measures on campus as deemed necessary and notify lab supervisors of their results and recommendations.

B. Engineering Controls—Criteria for Implementation (see Sec. II-15)

C. Administrative Controls—Criteria for Implementation

The variety of possible administrative controls to reduce hazard levels in laboratories is large, e.g., training, signage, labeling, SOPs, etc. The controls instituted by a given laboratory shall be determined by the lab supervisor in consultation with EH&S, as needed. In general, measures shall be implemented:

  • As indicated in Standard Operating Procedures
  • As mandated by health and safety regulations, or as called for by accepted good practice

Personal Protective Equipment—Criteria for Implementation

Appropriate personal protective equipment (PPE) practices are stipulated in the UC policy titled: Personal Protective Equipment (March 2014). The key provisions of the policy are summarized in Sec. II, pgs. 6 to 10 of this manual, including:

  • how to determine the appropriate PPE for the hazards present in a particular laboratory (via “LHAT”)
  • how to obtain free PPE on campus;
  • when and where to don PPE;
  • how to launder dirty laboratory coats
