Lab Safety?
Definition
Laboratory safety is a careful process, with the goal of preventing injuries and diseases from occurring among students, scientists, laboratory staff, and the community.
Lab safety rules inform students about specific precautions to take when doing lab procedures
Historical Perspective
“Who does not ruin his health by his studies,nowadays will not get anywhere in Chemistry.”
– Kekule, a Chemist in 1890
Today, scientists can design and conduct experiments for an entire career with no adverse health effects.
Lab Accidents
The most common injuries and diseases affect the muscular / skeletal system, the skin, and the eyes
MUSCULAR / SKELETAL
Slips and falls caused by
rushing, spills, and trip hazards
SKIN
Damage or burns caused by chemicals, electricity, or
heat
EYES
Irritation and damage from
chemical splashes and airborne
materials
All of these are preventable!
Common Injuries
Common Causes
There are several common reasons for injuries and accidents in labs. These can all be avoided!
Not preparing properly / not including a lab safety plan
Being careless / not paying attention to your work
Using unlabeled or mislabeled chemicals
Hurrying to complete a procedure
Using damaged equipment
Working by yourself
Prevention
The best way to prevent lab accidents is to be prepared and knowledgeable about what you will be doing before beginning and then continuing to be careful as you work
Know the equipment and materials you'll be using
Evaluate the lab environmentfor possible hazards
Follow the lab safety plan
Stay focused when you'redoing procedures
Hazard Symbols&
Guidelines
Glassware Hazard
Do not use cracked or broken items.
Do not heat or cool glassware unless it is specially designed to withstand large temperature changes.
Make sure glassware is clean & dry before use.
Use tongs or hot pads to handle hot or very cold glassware.
Electrical Hazard
Do not use electrical equipment or touch an outlet with wet hands.
Be sure plug is solidly inserted in the socket.
Remember that people (that's you) conduct electricity.
Avoid getting outlets/electrical equipment wet.
Flammable Hazard
Wear goggles when using a flame or handling hot liquids.
Never heat anything in the lab unless instructed to.
Don't reach across a flame.
Use tongs or padded gloves to handle hot objects.
Be sure the work area is clean when using a flame.
Poison Hazard
Never smell a chemical directly. Use the wafting method, but only when instructed.
Do not taste, touch, or mix chemicals unless instructed.
Keep chemicals away from your skin and face. Use protective gear such as goggles and gloves.
If any chemical gets on your skin or clothing, rinse it with water FIRST. Then notify the instructor.
Animal Hazard
Handle animals only when necessary and only as directed.
Do not cause pain, discomfort or injury to an animal in the lab; treat animals humanely.
After handling animals or their cages, wash your hands thoroughly.
Plant Hazard
Remember that some plants may be poisonous or have sharp components.
Never taste or eat a plant in the lab, even if it looks familiar or is a food item, unless instructed to do so.
Some people are allergic to plant components or oils on a plant’s surface.
Sharpness Hazard
Use specific cutting instruments and dissection tools designed for lab use.
Handle sharp instruments carefully and never point them at yourself or other people.
Cut with the sharp edge moving away from you.
If you are cut or jabbed, report it to the instructor immediately.
Gas Hazard
Materials (chemicals) may give off toxic gases or dangerous fumes may be created during lab procedures.
Work only in areas with proper ventilation. If toxic gas is suspected immediately move outside to get fresh air.
Our labs should not create toxic fumes. This depends a lot on YOU. It is very important you don't mix chemicals or heat items without being instructed to do so!
