Final answer:
Mandatory PPE in laboratories includes disposable nitrile rubber gloves, chemical splash goggles, laboratory coats, and possibly face shields or respirators depending on the experiment. Rubber gloves prevent direct skin contact with hazardous substances while goggles protect the eyes. A lab coat and other PPE help ensure personal and environmental safety.
Step-by-step explanation:
When working in a laboratory, it is crucial to adhere to safety protocols to protect oneself from potential hazards like sharp objects, chemicals, heat, and electricity. The mandatory personal protective equipment (PPE) for any lab session includes disposable nitrile rubber gloves, chemical splash goggles with side shields, a laboratory coat, and, depending on the risk assessment, possibly a full face shield or respirator.
Wearing rubber gloves helps prevent direct contact with harmful substances and should be disposed of in a biohazard garbage after use. Chemical splash goggles with side shields protect the eyes from any splashes or harmful vapors, while laboratory coats minimize skin exposure and protect personal clothing. For procedures with a high risk of inhalation of toxic fumes or particles, a full face shield or respirator may be required to provide additional respiratory protection.
It's essential to know the location of safety equipment like fire extinguishers and eyewash stations and to wear proper protective attire, including items one wouldn't typically wear outside a lab, such as protective footwear and a lab coat. Additionally, proper handwashing post-experimentation and appropriate waste disposal procedures are part of maintaining a safe laboratory environment.
