Chemical Hygiene Plan


Included below are templates to help you prepare a chemical hygiene plan, as well as guidance for appendices to  standard operating procedures in your CHP.


Appendix 1 - Laboratory Specific Standard Operating Procedure 

In addition to the Chemical Hygiene Plan Template, you must include your own laboratory specific SOP's in this Appendix. Please attach your own operating procedures, there is no template for this Appendix.

Appendix 2 - Lab Self-Audit checklist

Follow the Laboratory Self-Audit Checklist. See also the Question Guidance used in the self-audit.

Appendix 3 - Lab Close-Out Survey checklist 

Refer to the Lab Closure and Relocation Guide

Appendix 4 - Emergency Information and Contact Numbers

Use the In Case of Emergency call flow chart and include the contact numbers for your lab PI and lab supervisor on the sheet when you post it in a prominent position.

Appendix 5 - Hazardous Materials disposal procedures

Refer to the Hazardous Materials disposal procedures

Appendix 6 - Select Carcinogens

Refer to the Select Carcinogens list

Appendix 7 - Laboratory emergency procedures during power outages

It is important to remember that some equipment cannot be turned off and certain other pieces of equipment do not shut themselves off when there is a power outage. Pre-plan specific procedures for your laboratory while adhering to the following:

  • Close chemical fume hood sashes. No work is allowed in fume hoods during a power outage.

  • Ensure that all chemical containers are secured with caps, parafilm, etc.

  • All non-essential electrical devices should be turned off. Keep the doors of refrigerators and freezers closed. Check to ensure large lasers, radio frequency generators, etc have been turned off.

  • Turn off all gas cylinders at the tank valves.

  • If a low flow of an inert gas is being used to "blanket" a reactive compound or mixture, it may be appropriate to leave the flow of gas on. The decision to do this should be part of the written Standard Operating Procedure specific for each lab in Appendix 1.

  • Check all cryogenic vacuum traps (N2, CO2 and solvent). The evaporation of trapped materials may cause dangerous conditions.

  • Check all pressure, temperature, air, or moisture sensitive materials and equipment. This includes vacuum work, distillations, glove boxes used for airless /moistureless reactions.
