Which Tasks Require PI & EHS Approval
Some tasks require P.I. and EHS approval before performing alone or independently, including:
- Work with specific hazardous materials, such as, but not limited to:
- Cryogens (e.g., liquid nitrogen, liquid helium)
- Pyrophoric & explosive materials
- Highly reactive materials (e.g., strong oxidizers, acids, bases)
- Hydrofluoric acid
- Transferring large quantities of hazardous materials (i.e., >10L)
- Procedures that may create hazardous conditions (e.g., oxygen deficiency) or adverse outcomes if not well-controlled (e.g., exothermic polymerization)
- Work around high voltage
- Specific laboratory equipment
- Specific laboratory instrumentation
If your student (s) performs an essential lab function that require one of these tasks, consult with EHS to implement appropriate controls, such as a buddy system.
Hazard Review
- The P.I. and EHS will be conducting Hazard Review by looking at critical task and considering what can go wrong and how adverse impacts can be eliminated or reduced.
- High hazard of chemicals, operation of equipment, and /or biological agent will not be permitted to work alone or independently AT ALL.
- Requirement of administrative controls, engineering controls, and PPE.
- Elimination of the use hazardous materials if possible
- Substation of hazardous materials with a lower degree of hazard
- Performing all work with appropriate engineering control (s)
- Implementing a buddy system
- Wearing appropriate personal protective equipment (PPE)
- While working alone, select PPE more conservatively than you would in ordinary circumstances.
- Example, under ordinary circumstances relatively few tasks require a face shield, however, when working alone you may decide to wear a face shield at any time there is splash potential.
