Written SOPs for any particularly hazardous substance (PHS) or procedure that poses
a unique health risk must be developed and made available for all lab members. The
SOP describes how your lab will handle a hazardous material safely, including the
amount and concentration of material you will use, how you obtain or create the working
solution, special handling procedures, engineering controls, personal protective equipment,
and waste disposal considerations. The SOP must be read and signatures documented
by all personnel who may be exposed to the hazardous situation.
Please contact the Laboratory Safety Officer to request an additional SOP template
for a specific chemical or procedure.
PARTICULARLY HAZARDOUS SUBSTANCE (PHS)
A Particularly Hazardous Substance (PHS) is defined as a select carcinogen, reproductive
toxin, pyrophoric, water reactive, or acutely hazardous material. A list of Common Particularly Hazardous Substances is provided as a reference. For your convenience, SOP templates for some commonly
used hazardous chemicals and a General SOP template are available below. The templates
must be completed by the lab PI/Supervisor to include lab specific information, actual
procedures used, and must be read and signed by the lab personnel. The SOP is used
as documentation of lab specific training and should be available for review during
HIGH RISK PROCEDURES
High risk procedures are lab procedures which are likely to require engineering controls
beyond those found in the standard laboratory. These include the use of chemicals
or toxins which require medical surveillance, vaccination, special antidotes, or exposure
monitoring, and operations that pose significant risk of fire, explosion, or exposure
to personnel if a malfunction were to occur (utility outage, runaway reaction, broken
container, or chemical spill). Contact the Safety and Risk Management Office (828-227-7443)
if you have questions regarding High Risk Procedures or if you need to obtain permission
for any of the following procedures:
- Large quantities of liquid nitrogen or other cryogens which could deplete oxygen in
the air. Large quantities would be more than one freezer and one attached Dewar per
room, filling a cryocart or cooler, or liquid nitrogen (or other cryogen) piped in
from a tank located outside the building.
- Heat concentrated perchloric acid (requires a perchloric acid approved fume hood).
- Use pyrophoric gases or other reactive Particularly Hazardous Substances (PHS).
- Use hydrofluoric acid or other chemicals for which an antidote or specific first-aid
treatment is required.
- Use formaldehyde at the level which may require exposure monitoring or respirator
- Create or synthesize nanomaterials.
- Use botulinum toxin, tetanus toxin, or other toxins for which vaccination is recommended.
- Perform a procedure or use other equipment that is likely to require engineering controls
beyond those found in the standard laboratory.
