3. Implementation of Control Measures

 

3.1 Air Sampling

Air sampling to evaluate exposure of laboratory personnel to chemical substances shall be conducted as may be required by specific codes or regulations, or whenever there is reason to believe that the exposure level for a regulated substance that requires sampling routinely exceeds the ACGIH TLV or other action level, or in the absence of an action level, the Permissible Exposure Limit (PEL). If sampling indicates that such levels have been exceeded, remedial measures must be taken, in consultation with the CHO. In general, preference is to be given to adjusting the design or implementation of the experimental procedures, and/or utilizing additional engineering controls, before relying on respirators. If a decision is made to use respirators, their use shall be governed by the requirements of Section 2.9, Personal Protective Equipment.

3.2 Spill Response

All spills on lab benches or floors shall be immediately cleaned and properly disposed of. Small spills should be cleaned up by the user. For larger spills, immediately contact the Chemical Hygiene Officer, Laboratory Stores Manager, or the Director of Sciences Support Services, who will call in a contracted Hazmat Response team if the spill cannot safely be cleaned up by in-house personnel. All chemical wastes from spill cleanup must be disposed in accordance with Section 2.6.

3.3 Safety and Emergency Equipment

The faculty or staff member in charge of each laboratory area shall ensure that telephone numbers of personnel to be contacted in an emergency are posted. These listings are to include supervisors and other workers, as appropriate.

All laboratory personnel should familiarize themselves with the location and proper use of fire extinguishers. Specific training in the use of fire extinguishers will be made available by the College’s Environmental Health and Safety Coordinator.

Prior to the procurement of new chemicals, the supervisor needs to verify that existing extinguishers and other emergency equipment are appropriate for use with those chemicals.

All laboratory workers shall be instructed by their supervisors in the location and proper usage of emergency showers and eyewashes. Eyewashes and emergency showers are to be inspected weekly by the laboratory employees. Eyewashes will be tested regularly (generally weekly) by the Laboratory Stores Manager, and safety showers will be tested at least quarterly by Facilities Services.

Location signs for safety and emergency equipment will be posted.
