A. Critical Hazards Identification

1. Initial Hazards Assessment
Prior to the initial start up of a procedure or a substantial change in an existing procedure, the Laboratory Professor or Laboratory Instructor must evaluate the potential hazards associated with the work and the protective measures needed to control each hazard.  The following methods are acceptable means to do this:

1. Use the hazards identification checklist contained in Appendix C, Process Hazards Identification Checklist
2. Perform your own review, if it equals or exceeds the process in Appendix C, document the criteria used and record the findings.
3. The Chemical Hygiene Officer must be notified of any of the following:
   1. 1. 1. Work involving any chemical listed in Appendix D – OSHA Regulated Substances.
         2. Decision to use respiratory protection.
         3. Installation of alarms/sensors for the purpose of alerting the user that a hazardous condition exists.
         4. Project Process Changes Each process change must be evaluated in a manner similar to the initial evaluation.  A simple memo or a specific note in a laboratory notebook will be sufficient to document each change and associated evaluation.
