  • Bacterial loop: Used to transfer small amounts of bacteria.
  • Evaporating dish: Used to evaporate liquid samples.
  • Wire brush: Used for cleaning laboratory glassware.
  • Crucible and cover: Used to heat and or contain materials.
  • 24-well plate: A plate with 24 individual wells, used for various experiments.
  • Test-tube rack: Organised storage for test tubes.
  • Mortar and pestle: Used for grinding solids.
  • Lab burner: Used for heating substances.
  • Forceps: Used in handling small objects or specimens, preventing contamination
  • Wash bottle: Used for rinsing equipment.
  • Pipet: Used for precise liquid measurements.
  • Graduated cylinder: Used for measuring volume.

  • Funnel: Used to pour liquids into vessels with a small opening.
  • Dropper: Used to dispense measured drops of liquid.
  • Petri dishes: Used for growing microorganisms and experiments.

Preventative Measures in a Laboratory

  • Listen to instructions: Read or listen carefully before conducting any experiment.
  • Safety goggles: Always wear safety goggles to protect eyes from chemicals or potential hazards.
  • Notify teacher: If any accident or spill occurs, immediately notify the teacher or supervisor.
  • Wash hands: Wash hands thoroughly with soap and water after handling chemicals.
  • Tie back hair: Secure your hair to avoid it getting caught in equipment or experiments.
  • Avoid touching your face: Avoid touching your eyes, nose, or mouth while working.
  • Roll up sleeves: Roll up sleeves to avoid contamination or accidents during experiments.
  • Know emergency equipment locations: Locate and know the location of fire extinguishers, fire blankets, eyewash stations, and first-aid kits to use in case of emergencies
  • Keep work area clean: Keep the work area uncluttered to avoid accidents
  • Use necessary equipment: Use the equipment needed for your experiment without using unnecessary items.
  • No contact lenses: Avoid wearing contact lenses during experiments.
  • No eating or drinking: Do not eat or drink in the laboratory
  • Clean up: Clean your lab area and return everything to its designated place to maintaining a safe environment

Safety Signs in a Laboratory

  • Emergency signs: These signs show the locations of safety equipment (e.g., eye wash, shower).
  • Safety signs: Show hazardous materials (e.g., radioactive substances, toxic chemicals).
  • Specific protective equipment (PPE): PPE such as gloves, masks, eye protection
  • No food or drink in lab: Indicates that food and drink are prohibited in the laboratory.
