Never attempt to catch falling sharp instruments.
Only grasp sharp instruments by their handles to ensure safety.

Laboratory Health Precautions

Consult a physician regarding any medical conditions (e.g., allergies, pregnancy) before working in a lab.
Laboratory goggles are mandatory during any chemical, heat, or glassware activities; no exceptions allowed.
Wearing contact lenses in the lab is restricted and requires instructor approval.

Proper Laboratory Attire

Long hair should be tied back, and loose or dangling jewelry/clothing must be secured to prevent hazards.
Closed-toe shoes are required; sandals are prohibited in the laboratory.
Lab aprons must be worn during laboratory activities to protect clothing and skin.

Report any accidents (spills, breakages) or injuries (cuts, burns) to the instructor immediately, regardless of severity.
In case of personal injury, call out "Code one. Code one" to alert the instructor for assistance.
If chemicals splash in the eyes or on the skin, rinse immediately with water from the eyewash station or safety shower for at least 20 minutes and notify the instructor.
