Safety and Rules in Biology Laboratory
Safety and Rules in Biological Laboratory
1.2
Safety and Rules in Biological Laboratory
Self-protection Equipment
Gloves: to handle biological samples
Lab coat: aids to protect the skin and clothes from chemical spillage
Lab shoes: protects the legs from chemiccal spillage and broken glass
Goggle: protects eyes from hazardous chemicals
Face mask: protects against smoke, vapor and dust that can affect the respiratory system
Emergency shower station: used when the hazardous substances come into contact with the skin
Eye wash station: used to wash the eyes when exposed to hazardous substances
Fume hood: to avoid breathing in the hazardous gases such as chlorine, bromine and nitrogen dioxide
Laminar flow cabinet: provide a flow of filtered air for a clean work area in the laminar flow cabinet
Biosafety cabinet: provides an enclosed work space to study materials that have been (or are likely to have been) contaminated by pathogens
Substances That Cannot be Disposed in The Sink
Chemical substances, glass, metals, plastics, woods or any solid substances.
Grease, oil and oil paint.
Toxic substances; benzene, chloroform, hydrogen cyanide, argentum.
Heavy metals; mercury, lead, cadmium.
Radioactive wastes.
Reactive substances that are unstable; sodium metal, ether, hydrogen peroxide.
Substances That Can be Disposed in The Sink
Any liquid/solution that has low concentration, non-hazardous and easy to disintegrate
Methods for Managing Biological Waste
Sharp Waste
Examples: syringe with needles, nedles, glass and scalpel
Management method: placed into a special bin for sharp material disposal. This bin does not need to be sterilised.
Non-sharp Waste
Examples: gloves, tissue paper, Petri dish, agar, culture waste
Management method: throw it in the biohazard bag, sterilize it and throw it in the biohazard bin
Animal Carcases
Examples: organs, animal tissue waste, carcass
Management method: wrap it with tissue paper, put it in the biohazard bag and freeze it
Liquids
Examples: broth culture and liquid medium such as blood
Management method: decontaminate the waste through autoclave before throw it in the biohazard bin
Steps to Handle General Chemical Spills
Inform your teacher.
Declare the spill area as a restricted zone.
Prevent the chemical spill from spreading using sand.
Scoop up the chemical spill from using appropriate equipment..
Dispose it safely.
Steps to Handle Mercury Spills
Inform your teacher.
Declare the spill area as a restricted zone.
Sprinkle sulphur to cover the mercury spills.
Call the fire and rescue department.
Practices in a Biological Laboratory
Clothing Ethics
Use a lab coat, gloves, lab shoes and goggle when needed.
Laboratory Safety Rules
Do not work alone in the laboratory without supervision.
Wash your hand after conducting an experiment.
Do not bring in irrelevant items into the laboratory.
Clean your workstation using disinfectant.
Dispose wastes according to the set procedures.
Do not eat and drink in the laboratory.
Identify all safety symbols on substances and equipment before use.
Safety Measures of Fires
Stop work immediately and switch off all nearby power sources.
Unplug appliances
Exit the laboratory according to the emergency exit plan.
Call the fire and rescue department.
Do not panic and stay calm.
Do not turn back to collect your belongings
Assemble at the assembly point.
Handling Glasses and Chemicals
Be cautions when handling hot glassware.
Report any damaged equipment or glassware to teachers immediately.
Keep flammable chemicals away from fire sources.
Do not touch, taste and smell chemicals directly.
Handling Live Specimens
Use appropriate gloves when handling biological specimens.
Specimens that are not harmful and have been dissected should be buried or frozen.
Wash hands with antiseptic detergents before and after experiment.
All surfaces and workstations should be cleaned with disinfectant before leaving the lab.
Emergency Help
Inform your teacher.
Call the fire and rescue emergency number.
Remove the victim from the scene.
Give emergency treatment.
Make the place of accident as a restricted area.
