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:
