A. General Principles
Everyone in a laboratory should observe the following rules:
B. Health and Hygiene
The following practices should be observed:
In the event that a chemical is splashed into the eye, a contact lens may serve to trap and concentrate the chemical, thereby increasing the potential for eye damage. In some cases, the lens may dissolve or in some way become “glued” to the eye.
“Soft” contact lenses can absorb organic solvent vapors and thus potentially damage the eye.
There may be exceptional situations in which contact lenses must be worn for therapeutic reasons. In these situations, employees who MUST wear contact lenses MUST inform their supervisor so that appropriate safety precautions can be devised.
Minimize your potential for exposure by protecting against inhalation, ingestion, injection and absorption of chemicals.
C. Food, Beverages, and Chemical Contamination
The contamination of food, drink and smoking material is a potential route for exposure to hazardous chemicals. Food and beverages must be stored, handled and consumed in an area entirely free of hazardous chemicals. Smoking is prohibited in all buildings.
There is a definite relationship between safety performance and orderliness in the laboratory. Where housekeeping standards are lax, safety performance inevitably deteriorates. The work area must be kept clean, with chemicals and equipment properly labeled and stored.
stored in puncture-proof containers while awaiting disposal.
E. Laboratory Equipment Maintenance
Improperly functioning equipment may provide a false sense of safety and create hazardous situations.
Accidents involving glassware are a leading cause of laboratory injuries.
G. Protective Apparel and Equipment
A variety of specialized clothing and equipment is available for use in the laboratory. The proper use of these items will minimize or eliminate exposure to the hazards associated with most laboratory procedures. All laboratory personnel must be familiar with the location and proper use of protective apparel, safety equipment and emergency procedures.
Each laboratory should include:
H. Cryogenic Hazards
The primary hazard associated with cryogenic materials is the extreme cold and potential for thermal burns. These burns can be severe.
I. Systems Under Pressure
J. Warning Signs and Labels
Laboratory areas that have specific hazards must be posted with warning signs.
K. Unattended Operations
It may be necessary to conduct laboratory procedures over extended periods of time or to run equipment continuously.
L. Working Alone
Avoid working alone in a laboratory. If this is not possible:
M. Laboratory Security
For the protection of employees, students, equipment, supplies, and the public, laboratories must be locked when unattended.
Security within the laboratory is also important. Locked storage cabinets are advised for sensitive or expensive supplies and equipment. Lockable storage areas or lockers for securing personal property are advised. Needles and syringes must be secured.
Computers, scientific equipment, and research data can be the object of theft, vandalism, or damage from fire or utility failure. Appropriate cabinetry designed to protect these items should be considered. Upon request, Campus University Police can assist laboratories with crime prevention surveys and recommendations.
If you observe suspicious persons or activities in your area, contact Campus University Police (x6666) and an officer will be sent to investigate. Report any thefts or other crimes immediately. Information from these reports is used to adjust patrol activities and may prevent further problems.
