For classroom science teachers to work effectively in the safety field, they need to see how OSHA definitions apply to the laboratory. OSHA definitions are vital to creating chemical hygiene plans. They help to encourage comprehension of standard working methods. This thus helps science teachers better arrange and work toward getting and keeping a safer work environment in the laboratory for all occupants.

To control a representative's exposure to chemicals and other dangers in the science laboratory, OSHA has encouraged three general fundamentals of laboratory safety standards. These include:

Engineering controls or environmental settings/considerations

Administrative controls, including work practices or standard working strategies (SOPs)

Personal protective equipment or body protective material

By planning laboratory work utilizing one of these fundamentals or a blend of them, representatives can keep their exposure levels well beneath OSHA admissible exposure cutoff points or PELs.

There is a progressive system of the guard to shield understudies and teachers from exposure ...
... to unsafe chemicals. The pecking order is as per the following in execution:

The first line of defense — engineering controls (environmental settings/considerations).

Second-line — administrative controls (work practice).

Third line — personal protective equipment (body protective stuff).

A. Engineering Controls (Environmental Settings/Considerations)

Engineering controls are OSHA's favored technique in managing laboratory risks. These controls eliminate or lessen exposure to a chemical or actual peril by utilizing or subbing designed hardware or equipment. Models incorporate the accompanying:

Choice of a less poisonous chemical.

Substitute cycle to limit collaboration with hazardous chemicals.

Utilization of wet strategies to decrease the generation of dust or other particulates.

Sound housing materials for the decrease of noise levels.

General laboratory ventilation.

Disengaged exhaust, for example, a smoke hood.

B. Administrative Controls (Work Practices)

Administrative controls or work rehearses include changes in work techniques to more readily secure the representative. This can be accomplished through-composed safety conventions/approaches/strategies, supervisory exercises, and representative preparing/resources. Models may include:

Housekeeping — keeping the laboratory work territory away from mess will lessen the chance of an accident.

Forbidding general access of non-science representatives to laboratories where dangers, for example, power, chemicals, and warmth sources, are being utilized.

C. Personal Protective Equipment

In situations where engineering controls are not adequate to give workers exposure protection, personal protective equipment should be utilized. Personal protective equipment incorporates clothing or devices worn to help shield a worker from direct exposure to a safety risk or circumstance. Instances of personal protective equipment incorporate protective clothing (aprons), hand protection ( safety gloves), and eye protection (chemical sprinkle goggles and safety goggles). Safety Data Sheets are a decent resource for suggested personal protective equipment when working with hazardous chemicals.
