Chemical Hygiene Plan

10.0 Cal/OSHA Regulated Carcinogens

WESTMONT COLLEGE IS EXEMPTED FROM 8 CCR 5209 (Carcinogens) except for Section 5209(c)(6) - Laboratory Activities) by Section 5191(a)(2). Therefore, this section of the Plan does not address any other sections of 5209.

This section discusses additional requirements that shall be observed for laboratories which handle Cal/OSHA Regulated Chemical Carcinogens. Note that Cal/OSHA allows exceptions to the carcinogen standard if the compound is used at or below the exempt carcinogen levels (i.e., the compound may be diluted to below the exempt concentration as measured by weight or volume in solid or liquid mixtures, as indicated in Table 10.1 below).

10.1 Responsibilities

The use of Cal/OSHA Regulated Chemical Carcinogens requires additional responsibilities beyond those outlined in other sections of the Plan. Responsibilities are assigned as follows:

10.1.1 Public Safety:

  • Registering with the Division of Occupational Safety and Health (DOSH) where regulated carcinogens are used at Westmont College.
  • Maintaining a current inventory of Cal/OSHA Regulated Chemical Carcinogens.
  • Investigating all reported accidents which result in the exposure of personnel or the environment to a Cal/OSHA Regulated Chemical Carcinogen and recommending corrective action to reduce the potential for recurrence.
  • Reporting to Cal/OSHA incidents which result in the release of a Cal/OSHA Regulated Chemical Carcinogen into areas where employees may be potentially exposed.
  • Ensuring that information regarding asbestos, a Cal/OSHA Regulated Chemical Carcinogen, is available to building occupants.

10.1.2 Principal Investigator (PI):

  • Assigning duties involving Cal/OSHA Regulated Chemical Carcinogens to Carcinogen Users and ensuring they are trained in the hazards of the operation prior to the assignment.
  • Preparing SOPs for specific Cal/OSHA Regulated Chemical Carcinogens or processes using Cal/OSHA Regulated Chemical Carcinogens and submitting them to the SO/CHO for review and approval.
  • Contacting Public Safety to arrange for personal exposure monitoring if area concentrations are suspected to exceed Cal/OSHA action levels.
  • Ensuring Cal/OSHA Regulated Chemical Carcinogen Users, who work in designated areas, know and follow the requirements for the carcinogen used, including the contents of the SOPs.
  • Selecting work practices, personal protective equipment and engineering controls for handling Cal/OSHA Regulated Chemical Carcinogens.
  • Ensuring engineering controls outlined in Section 10.4 are installed and used.
  • Arranging for immediate medical attention and reporting to the SO/CHO and Public Safety any accident that results in exposure to Cal/OSHA Regulated Chemical Carcinogens.
  • Correcting work errors and conditions that may result in the release of Cal/OSHA Regulated Chemical Carcinogens.

10.1.3 Laboratory Personnel:

  • Reporting to the PI or immediate supervisor all facts pertaining to each accident resulting in exposure to Cal/OSHA Regulated Chemical Carcinogens.
  • Knowing and following the requirements for the carcinogen used, including the contents of the SOPs.

10.1.4 SO/CHOs:

  • Knowing whether Cal/OSHA Regulated Chemical Carcinogens are handled in the building.
  • Maintaining an inventory of Cal/OSHA Regulated Chemical Carcinogens and a list of designated workplaces for use.

10.1.5 Administrative, Maintenance and Janitorial Personnel:

  • Checking with their supervisor, the PI, and the SO/CHO regarding the current status of operations involving Cal/OSHA Regulated Chemical Carcinogens.

10.2 Inventories and SOPs

PIs intending to handle or that are currently handling any Cal/OSHA Regulated Chemical Carcinogens or Known Human Carcinogens must submit a SOP to the SO/CHO for addition to the Departmental Safety Plan. Additionally, the PI, with the assistance of the SO/CHO, shall maintain a carcinogen inventory.

10.3 Reporting of Use to Cal/OSHA

Using the information provided by PIs in their chemical inventories and SOPs, Public Safety will submit a "Carcinogen Report Of Use Form" as specified in Cal/OSHA regulations on behalf of the entire College.

10.4 Engineering Controls

Cal/OSHA Regulated Chemical Carcinogen Users are required to comply with the following engineering control methods in addition to those outlined in Section 6.0.

  • Experiments, procedures and equipment which could produce aerosols shall be confined to laboratory hoods or gloveboxes.
  • Laboratory vacuum systems shall be protected with high efficiency scrubbers or with disposable absolute (HEPA) filters (except for beta-propiolacetone, bis-chloromethyl ether, methyl chloromethyl ether or ethyleneimine: only high efficiency scrubbers may be used).
  • Air pressure in laboratories and animal rooms where Cal/OSHA Regulated Chemical Carcinogens are handled shall be negative in relation to the pressure in surrounding areas.
  • Exhaust air shall not be discharged unless it has been decontaminated.
  • There shall be no connection between areas where Cal/OSHA Regulated Chemical Carcinogens are handled and any other areas through the ventilation system.
  • Laboratory hoods and other ventilated apparatus shall be tested at least semi-annually or immediately after modification or maintenance. Testing shall be done by fully qualified personnel.

10.5 Work Practices, PPE and Decontamination

The following procedures shall be followed by Carcinogen Users in addition to those described in Section 4.0 - Standard Operating Procedures (SOPs), Section 7.0 - Personnel Protective Equipment, and Appendix A - General Health and Safety Procedures:

  • Mechanical pipetting aids shall be used for all pipetting procedures. Mouth pipetting is prohibited.
  • Before leaving an area where Cal/OSHA Regulated Chemical Carcinogens are handled personnel shall:
    • Wash hands, forearms, face and neck, close to the point of exit, and before engaging in other activities.
    • Remove and leave protective clothing and equipment at the point of exit.
10.6 Disposal

In addition to disposal requirements outlined in Appendix A - General Health and Safety Procedures, the following actions shall be taken for Cal/OSHA Regulated Chemical Carcinogens:

  • Contaminated wastes and animal carcasses shall be collected in impervious containers, which are closed and decontaminated prior to removal from the work area.
  • Contaminated wastes and animal carcasses shall be incinerated in such a manner that no carcinogenic products are released.
  • Other forms of a carcinogen shall be inactivated prior to disposal.

10.7 Exposure Monitoring

  • EH&S shall conduct personal exposure monitoring for regulated carcinogens if area concentrations exceed Cal/OSHA action levels (or in accordance with specific regulations if there is no action level), as specified by Article 110.
  • Exposure monitoring results shall be reported to the employee according to the time frame required by the specific regulation.

10.8 Notification of Emergencies to Cal/OSHA

  • In an uncontrolled or an exposure incident of any regulated carcinogen, the SO/CHO, Public Safety and HR must be immediately notified.
  • Within 24 hours, HR shall report to Cal/OSHA incidents which result in the release of a Cal/OSHA Regulated Chemical Carcinogen into any area where employees may be potentially exposed, including facts about the occurrence and any medical treatment administered.
  • Within 15 days, HR shall issue a written report to Cal/OSHA including:
    • A specification of the amount of material released, the amount of time involved, and an explanation of the procedure used in determining this figure.
    • A description of the area involved and the extent of known and possible personnel exposure and area contamination.
    • A report of any medical treatment of affected personnel and any medical surveillance program implemented.
    • An analysis of the circumstances of the incident and measures taken, or to be taken with specific completion dates, to avoid similar releases.
