Physical Facilities

Isolated Systems

  1. Physical facilities for use of Extreme carcinogens shall be capable of providing either an isolated system or a totally controlled access facility with an independent ventilation system. For most uses, the most practical alternative is a glove box with an appropriately treated exhaust system approved by EH&S.
  2. Laboratory must be under negative pressure with respect to general access areas such as hallways and offices.
  3. The following criteria are required of all laboratories in which Extreme carcinogens are used or stored:
    • Isolated systems must be provided with an approved exhaust treatment system.
    • Isolated systems and approved storage cabinets must be labeled "Caution - Select Carcinogen."

Working Outside Isolated Systems.

If the procedures involved in the use of Extreme carcinogens cannot be contained in an approved isolated system, the following features must be provided in the laboratory:

  1. Laboratory must be under negative pressure with respect to general access areas such as hallways and offices.
  2. Entrances must be posted with "Cancer Suspect Agent."
  3. Vacuum lines must be appropriately protected to prevent entry of the carcinogens used into the lines.
  4. Prior to commencing work with chemical carcinogens, the laboratory ventilation system must be approved by EH&S.
  5. Laboratory work surfaces shall be protected from contamination by the use of disposable, absorbent paper with moisture-proof backing.
  6. Authorized entry into the laboratory must be regulated by a system approved by the Chemical Safety Committee.

  8. General room exhausts, glove boxes, laboratory hoods, or biological safety cabinets shall be equipped with approved exhaust treatment systems. (The appropriate exhaust for any carcinogen is dependent upon the nature of the compound and will be determined in the protocol phase of the experiment. Recommended equipment for treatment includes, but is not limited to, HEPA filters, activated charcoal filters, exhaust incinerators, and/or chemical scrubbers.)
  9. Provision shall be made for shower facilities and the management of protective clothing in the regulated area.
  10. The regulated area must contain a roster of persons who enter the facility.

Animal Care Facilities.

Storage and Labeling

Labeling of Containers.

  • All reagent bottles, stock, and working solutions shall be labeled "Caution - Select Carcingen"

Storage.

  • Working solutions of carcinogens shall be stored in sealed, primary containers, placed in unbreakable secondary containers, and stored in an approved, labeled storage area. The secondary container shall be sealed.

  • Such records shall be maintained for the duration of the employee's or student's work with Extreme carcinogens.
  • Upon termination of the employee's services, including retirement or death, the records of evaluations (or copies thereof) shall be forwarded to Oregon OSHA. Student records will be maintained for 30 years in the OSU Archives.
  • These records include dates of examinations, name of physician, and general statements; they DO NOT include diagnoses, specific lab tests, findings, etc.

Physician requirements

  • Departments will request that any physician conducting a carcinogen-related medical examination will furnish to the employer a statement of the employee’s suitability for employment in the specific exposure.

Inspections Required

All projects using Extreme carcinogens are subject to periodic inspections (announced or unannounced) by EH&S or the Chemical Safety Committee in order to insure safe conditions and procedures. EH&S or the Chemical Safety Committee may also inspect any project where potentially carcinogenic chemicals are being used.Inspections of projects using Extreme carcinogens will include, in part:

  1. A review of the physical facilities to see if enclosures and other safety equipment are functioning correctly.
  2. Determination that materials required to cope with accidents are readily available and emergency procedures are displayed.
  3. Determination that all personnel involved in the project are familiar with appropriate normal and emergency procedures and are aware of the potential hazards of the work of their own group as well as those of any other group with whom the facilities are shared.
  4. Determination that appropriate procedures for biological, physical, and chemical containment are consistent with approved protocols.
  5. Review of the roster maintained at regulated areas where the Extreme carcinogens are used. (See Laboratory Use of Extreme carcinogens Outside Isolated Systems, this section).
  6. Review of the inventory of Extreme carcinogens.

The results of inspections will be brought to the immediate attention of the principal investigator, the department chairperson, and reported to the chairperson of the Chemical Safety Committee. Inspection reports will be retained as part of the permanent files of EH&S.

Posting of Emergency Procedures

Approved specific emergency procedures shall be prescribed and posted in areas using Extreme carcinogens. The posted information shall include, but not be limited to:
