Under California law (OSHA),
supervisors (PIs) are required to: "
include procedures for
identifying and evaluating work place hazards including scheduled periodic
inspections to identify unsafe conditions and work practices."
Also, both SB County Fire and the CA State Fire Marshal expect that
labs do regular inspections and corrections of safety problems.
Accordingly, lab supervisors (PIs) and departments are responsible for performing regular safety inspections using the checklist below, or equivalent. EH&S will audit the departments program on an annual basis with its own lab visit.
This is not a list of every possible hazard, but can be utilized as a guide to conduct your own safety surveys. The items listed are based on applicable regulations, codes or campus policy. Note that radioactive and biohazard usage issues are not addressed here because they are highly specialized and these labs receive targeted EH&S inspections. Contact the Radiation Safety Officer or Biosafety Officer for more information.
Are the eyewash and emergency shower stations tested quarterly by Facilities and free of any obstructions which would prevent ready access? Labs should run their eye wash units monthly to assure that the water lines are kept clean.
Have fume hoods been EH&S tested within the year (check sticker)? Is air flow indicator present and operational? Is storage within the hood minimized? Are air entry slots at back of hood kept clear of obstructions? Is the front sash lowered to the appropriate level when hood is in use?
Are biological safety cabinets certified annually or when moved (check sticker) and are they the proper types for the work being conducted?
Do labs using non-ionizing radiation equipment, such as lasers, microwaves, and ultraviolet light sources, have properly posted warning signs and shielded work areas?
- Are cylinders dated upon arrival and contents clearly identified?
- Inspect regularly for defects, i.e., excessive rust, dents, bulging, corrosion, etc.
- Unidentified cylinders should be marked, "CONTENTS UNKNOWN" and returned to the manufacturer.
- Non-lecture bottles > 5 years old must be returned to the manufacturer to ensure they are safety/pressure tested as required by law ("hydostatic testing") Check stamped date on cylinder when it was last tested.
-Corrosive gases (e.g. HF, HBr, HCl, H2S) can degrade the cylinder over time and/or produce dangerously high pressures of hydrogen. Dispose of within 2 years.
-Are cylinders secured upright with welded chains and brackets bolted to a wall, bench or other secure object
- Are protective caps in place while cylinders are not in use?
- Use of large cylinders of highly toxic gases must be reviewed/approved (contact EH&S, x-4899)
-Flammable gases (e.g. hydrogen, methane) tubing should be equipped with a flash arrestor to prevent flame flashback to cylinder. Available from gas vendors.
-Gas cabinets with toxic
or flammable gas delivery manifolds often have an excessive flow
detection and auto-shutoff valve built-in. Verify that this safety feature
Are toxic gases being used with the required controls? (contact EH&S)
-Highly toxic gas cylinders
should be equipped with a reduced flow orifice (RFO) connection to prevent
rapid discharge of cylinder contents. Available from gas vendors.
for storing flammables clearly posted with signage indicating they are
safe for such storage? (e.g. “desparked”, “lab-safe”,
“explosion-proof”, “flammable storage”).
- Are refrigerators that are NOT designed for flammables storage clearly marked as such? (this is very important to prevent a potential explosion)
- Are all chemical storage refrigerators marked with “No Food” labels?
- Refrigerators in labs utilized for food or drinks should be marked “Food Only/No Chemicals?”
Is the location of manuals /instructions for each piece of equipment known?
Are the belt guards in place on all pumps, etc?
Flow and Pressure Controls:
Cooling Water Systems - for hot processes that demand a constant flow of cooling water, particularly those that are left unattended, (e.g. solvent stills) it is important to have a flow monitoring device in place. These devices are programmed to shut-off electrical power when the cooling water flow is insufficient. These are commercially-available and currently available at the Chemistry Dept. Electronics Shop.
- Inspect and test all high pressure vessels regularly per the owners
manual requirements. Each vessel should have a use-log of: experiment
conditions, dates of runs, testing/maintenance history, etc. in order
to track the vessel's life-expectancy. Pressure vessels must include
a functional over-pressurization rupture disk to prevent a catastrophic

Are flammable liquids stored in closed metal safety cans or flammable storage cabinets whenever possible?
Are flammable liquids always stored in flammable cabinets when in excess of 10 gallons?
Do you have large volumes of flammable solvents (e.g., multiple cases or drums) in storage that are above what is reasonably needed? The quantities of flammables that can legally be stored are regulated by CA Fire Code. Please don't stockpile large quantities of these materials.
