1. SAFETY IN THE LABORATORY

2. Lab Safety
Successful work in the chemistry laboratory involves not only mastery of chemical concepts and techniques, but also knowing:
what the safety requirements are,
what equipment is available, and
when and how to use each piece of equipment.
Safety regulations are established for each laboratory
by Federal, State, and School mandates.

3. Eye Protection
Whenever anyone is working with chemicals or apparatus in the laboratory, safety goggles are required for ALL persons in the laboratory.

4. Proper Clothing Tie back loose hair! Avoid floppy clothing! Store
belongings
out of the
way!

5. Lab Safety Equipment
In case of an emergency, you should know the location and proper use of all the safety equipment provided in the laboratory.
Always immediately inform the instructor of any accident.

6. Lab Safety Equipment eye wash station safety shower
fire safety blanket
fire extinguisher
first aid kit
fume hood/ventilation
gloves & aprons
tongs/cooling pads
waste containers
spill kit
goggle cabinet

7. Safety Eyewash
Any chemical contacting one’s eyes should be immediately and thoroughly rinsed out using the safety eyewash found in every laboratory.

8. Position head
between spigots.
Push handle to start
the flow of water!
Flushing for 15 minutes is standard (minimum) procedure.

9. Safety Shower
Any chemical spill on a person should be washed off immediately and thoroughly using the safety shower.
Pull the chain to start
the flow of water!

10. Safety Shower
Remove all contaminated clothing and stand under the shower.
Pull the chain to start the flow of water.
Washing should continue long enough to insure complete removal of the chemical, at least minutes.

11. Fire Blanket
In case of a clothing fire, a fire blanket should be used.
Remove the fire blanket from its container using the straps.
Wrap it around the person to completely cover the person and smother the fire.

12. Fire Extinguishers (3) Squeeze handles. (2) Pull out locking key. (1)
Aim nozzle
at base of
fire.

13. First Aid Kit

14. Gloves Whenever handling corrosive or toxic materials,
protective gloves should be worn.

15. Lab Aprons Tongs See Mr. Warner for Apron if needed.
Use to move hot glassware or metal

16. Waste Disposal Discard waste as needed, during
and at the end of each laboratory period.

17. Waste Disposal

Waste Basket

19. Broken Glassware BOX
Broken glass or single-use glassware should be placed in the broken glassware box after any disposable contents have been removed.

20. Solid and Liquid Chemicals Never rinse chemicals down the drain!
Solid and liquid chemicals need to be placed in appropriate containers.
The exact means will be given in the lab procedure or specified by the instructor.
Never rinse chemicals down the drain!

21. Spill & Fire Kit: Bicarbonate, Sand
Located on lab benches are containers of sodium bicarbonate to neutralize acid spills, plus sand containers for small fires.
These work by covering either the spill of acid or the fire with a solid.
Each needs to be cleaned up and disposed of in a specific manner.
Be sure that the instructor is notified if any of these materials have been used.
