Study Notes

Safety Equipment and Protocols

Familiarize yourself with the locations of safety equipment: first aid kit, eyewash station, safety shower, fire extinguisher, and fire blanket.
Know how to operate all safety equipment; it is essential for responding to emergencies.
Always handle knives and sharp instruments with tips pointing down and away from the body; cut away from yourself.
Never attempt to catch falling sharp instruments; grasp only by the handles.

Laboratory Environment

Work in a well-ventilated area; use fume hoods when dealing with volatile substances or poisonous vapors.
Avoid placing your head inside fume hoods during operations to prevent inhalation of hazardous fumes.

Personal Conduct and Dress Code

Conduct yourself responsibly at all times in the lab; stay alert and cautious.
Long hair must be tied back, and dangling jewelry should be secured to avoid hazards.
Wear proper footwear that fully covers the foot; no sandals allowed.
Laboratory aprons should be worn during activities to protect clothing and skin from spills.

Chemical Handling and Disposal
