have a lighted exit sign on at all times.
2.
Know the location and use of safety showers, eyewashes, and first-aid kits.
3.
Know where the fire extinguisher and fire alarm pull boxes are located and how they operate.
4.
Know the location of the nearest phone which can be used in an emergency. Critical phone
numbers should be posted nearby.
5.
Know the potential hazards of the materials, facilities, and equipment with which you work. If you
are uncertain, ask your supervisor or contact Environmental Health and Safety (EH&S), 7521493.
6.

Use caution when wearing contact lenses in the laboratory. Anyone wearing contact lens in the
laboratory should be aware of the additional risks. Refer to SafetyNet #5 - Safety Guidelines For
Staff Who Wear Contact Lenses.
9.
Wear other personal protective gear where laboratory or experimental conditions dictate. This
includes lab aprons, lab coats, gloves, gauntlets, glass blowers’ goggles, face shields, dust
masks, respirators, and other equipment.
10.
Wear clothing that protects the body against spills, dropped objects, and other accidental
chemical contact.
Clothing that fully covers the legs and feet is strongly recommended.
Minimum protective clothing for handling hazardous materials includes safety glasses,
appropriate chemical resistant gloves, laboratory coat and closed-toe/heel shoes. Shorts and
open-toed shoes when handling hazardous materials and bare feet are prohibited.
11.
Long hair should be tied back or otherwise confined. Secure ties or other articles of clothing or
jewelry that might become entangled in equipment.

Prior Approval
Employees must obtain prior approval from their supervisors to proceed with a lab task whenever:
1. The standard operating procedure is being significantly modified.
2. A new lab procedure or test is to be carried out.
3. There is a failure of any of the equipment used in the experiment or process.
4. The toxic limit concentration could be exceeded or that other harm is likely.
Spills and accidents
For spills of one pint or more of a hazardous substance or any amount of an extremely toxic
substance, call 911, from a cell (530) 752-1230. For smaller amounts, follow the general guidelines in
SafetyNet #13 - Guidelines for Chemical Spill Control.
Other SafetyNets to be included in this section are:(1)#11 - Guidelines for the Safe Use of
Formaldehyde;(2) #37 and #56 for Radioactive Spills, and (3)#16 - Guidelines for Mercury Spill Control.
PROCEDURE-SPECIFIC SAFETY PROCEDURES
Procedures for Toxic Chemicals
The MSDSs for many of the chemicals used in the lab will state recommended limits, OSHA or
CAL/OSHA mandated limits, as guidelines for exposure. When such limits are stated, they will be
used in determining the safety precautions, control measures, and safety apparel to be used. A
Standard Operating Procedure must reflect the necessary precautions that are to be taken.
Refer to SafetyNet #33 - Hazardous Substances Information and Training.
Procedures for Flammable Chemicals
Refer to SafetyNet #19- Flammable Material Storage and Handling section.
Procedures for Reactive Chemicals

Proper
CONTROL MEASURES AND EQUIPMENT
Safety while using hazardous materials is achieved by continual awareness of hazards and by keeping
the material under control by using precautions, which include but are not limited to, engineering
controls (fume hoods, glove boxes, laminar safety cabinets). All engineering controls must be properly
maintained, inspected on a regular basis, and never beyond their design or limits.
Ventilation
1. Refer to SafetyNet #19 - Lab Hoods section.
2. The number of air changes per hour shall be 6 to 10 for each lab or area where hazardous material
are used or stored.
3. The lab ventilation systems shall be designed to separate clean and (potentially) hazardous areas
with no recirculation of lab air.
4. Recirculation of air shall be limited to office-type situations with a minimum of 20 cfm fresh air
make-up per person.
Flammable-Liquid Storage
Refer to SafetyNet #19 - Chemical Storage and Flammable Material Storage and Handling sections
(use parts as needed).
