Lab 1: Lab Safety
Introduction
Laboratory work is an essential part of understanding biology. While labs are designed to be safe, accidents can occur if proper care is not taken. Every student is responsible for knowing and following laboratory safety rules. These practices protect you, your classmates, the instructor, and the integrity of the scientific work.
General Safety Rules
-
Preparation
- Read the lab procedure before coming to class.
- Bring only approved materials (lab manual, notebook, pen/pencil, calculator).
- Know the location of safety equipment: fire extinguisher, eye wash station, safety shower, first aid kit, and emergency exits.
-
Personal Protective Equipment (PPE)
- Always wear safety goggles when handling chemicals, heat, or sharp instruments.
- Wear a lab coat or apron to protect clothing.
- Closed-toe shoes are required; sandals and open shoes are not permitted.
- Tie back long hair and avoid loose clothing or dangling jewelry.
-
Conduct in the Laboratory
- No eating, drinking, or chewing gum in the lab.
- Keep work areas clean and uncluttered.
- Handle equipment and specimens carefully.
- Never work alone in the lab.
-
Chemical and Biological Safety
- Treat all chemicals and specimens as potentially hazardous.
- Do not taste or directly inhale chemicals; use wafting if instructed.
- Dispose of all waste in designated containers.
- Wash hands thoroughly with soap and water after handling chemicals, organisms, or lab equipment.
-
Glassware and Equipment Safety
- Inspect glassware for cracks or damage before use.
- Handle hot glassware with tongs or heat-resistant gloves.
- Turn off burners, hot plates, and microscopes when not in use.
-
Emergency Procedures
- Report all accidents, spills, or injuries immediately to the instructor.
- If chemicals contact skin or eyes, flush with water for 15 minutes.
- Know evacuation routes and follow instructions during emergencies.
Lab Safety Agreement
Before beginning any lab work, each student must sign the Lab Safety Agreement (distributed in class). This confirms that you have read, understood, and agreed to follow all safety rules. Failure to follow safety guidelines may result in removal from the laboratory.
