Study Notes
UMST Preparatory College Biochemistry Practical NO (1): Lab Safety
- This practical focuses on lab safety procedures
- Students must adhere to safety guidelines before, during, and after lab work.
Preparing for Laboratory Work
- Before working in the lab, familiarize yourself with:
- Hazards of lab materials
- Material labels
- Proper handling procedures
Throughout Laboratory Work
- Obey these guidelines:
- Children are not allowed in the lab
- Avoid eating, drinking, smoking, using cosmetics, or handling contact lenses.
- Wear a closed, clean lab coat (knee-length) at all times.
- Do not wear open-toed shoes like sandals.
- Walk, do not run, in the lab.
- Keep exits and hallways clear.
- Only work with materials you've been instructed to use.
- Remove damaged equipment immediately.
- Do not leave reagent bottles (full or empty) on the floor.
- Return unused materials to their original location.
- Wash the equipment you used.
- Wash your hands thoroughly.
Hazardous Materials
- Hazardous materials can cause health issues, injuries, or property damage if not handled correctly.
- This includes solids, liquids, and gases that can harm people, organisms, property, or the environment.
Special Precautions for Working with Heat or Fire
- Never leave a lit Bunsen burner or hot object unattended.
- When an object is removed from the heat, place it where it's shielded from contact to cool down.
- Inflammable liquids should never be left open, near a naked flame, hot electric element, or electric motor.
- Use test tube holders to handle hot lab equipment.
- Always point the open end of a heated container away from yourself and others.
- Only use Pyrex glassware for heating.
- Allow hot materials to cool before moving them.
- Ensure Bunsen burner hoses are tightly connected.
Special Precautions for Working with Chemicals
- Never taste or touch substances without specific instructions.
- Never smell substances without specific instructions.
- Use chemicals only from properly labeled containers.
- Wash hands after working with chemicals.
- Do not add water to acid; always add acid to water to dilute it.
- Mix heat-generating chemicals slowly.
Special Precautions for Working with Electrical Equipment
- Ensure the area surrounding electrical equipment is dry to avoid accidents.
- Avoid touching electrical equipment with wet hands.
- Keep the area around electrical equipment free from flammable materials.
- Turn off power switches before plugging and unplugging appliances.
Special Precautions for Working with Glassware
- Familiarize yourself with glassware and equipment in the lab.
- Do not use broken or chipped glassware.
- Make sure glassware is clean before use.
- Do not pick up broken glass with your bare hands; use a pan and a brush.
Special Precautions for Working with Live or Preserved Specimens
- Treat live specimens gently and follow instructions for proper care.
- Wash hands after handling live or preserved specimens.
- Properly mount and support specimens for dissection.
- Do not cut specimens while holding them in the air.
- Do not open Petri dishes containing live cultures unless instructed.
- Use detergents (e.g., 5-10% detol) to sterilize and clean benches, glassware, and equipment.
- Wear lab coats
Hazard Warning Symbols
- A system of pictures warns of potential dangers in the lab; these are known as safety symbols.
Toxic
- Toxic chemicals can cause death if they penetrate the skin, are smelled, or swallowed.
Flammable
- Flammable substances ignite easily with heat or electricity.
Corrosive
- Corrosives destroy tissues, especially soft tissues.
Explosives
- Explosives are extremely dangerous, and need special handling according to lab procedures.
First Aid
- Immediately follow appropriate first-aid procedures if any injuries occur, for instance:
- Bleeding control: bandages and cleansing with iodine alcohol mixture
- Acid or fire burns: wash with water immediately
- Poisoning: identify the substance and seek appropriate treatment
- Skin contamination: wash with water to remove contaminants, and potentially soap if insoluble
