2. SAFETY EQUIPMENT IN THE CLASSROOM
Safety shower - for clothing fires as well as extensive chemical spills on body.
Fire extinguisher - for fires NOT on a person
Chemical Fume Hood- Sucks up chemical fumes in the lab
Gas Detectors in ceiling
Goggles - for eye protection
Eyewash station - for flushing of the eyes
Fire blanket - for smothering clothing fires
Electric Shut-Off Button – turns off all the electric outlets

3. WHEN TO WEAR YOUR SAFETY GOGGLES
Always wear safety goggle’s when you use:
chemicals
heating materials
glassware

4. Chemical Eyewash Station
This is not meant to be played with.

5. Fire Blanket
Used to smother out small fires.

6. CHEMICAL SAFETY SHOWER
Used to flush copious amounts of chemicals off your body.
copious= (large amounts of)
May have an eye wash station attached to it.

7. Emergency Electric Shut Off
Only push this button in case of an electric fire in the classroom.

9. CHEMICAL FUME HOOD

10. APPROPRIATE CLOTHING
Loose fitting clothing or jewelry can get damaged by equipment, chemicals, or heating devices.

11. HAIR INSTRUCTIONS
Tie back long hair when using chemicals, heat, or equipment with gears or spinning parts.
Caution, hair preparations such as hairspray, gels, and mousse are often very flammable.

12. ELECTRICAL HAZARDS
The main concern when using electricity in laboratory situations is electrical shock.
The human body is a good conductor of electricity.

13. MECHANICAL HAZARDS
The main concern is that loose clothing or hair will be caught in the machinery and will cause bodily damage.
Objects that come into contact with a spinning component can cause sparks or can damage the equipment.

15. DELAWARE’S HAZARDOUS CHEMICAL INFORMATION ACT
Is better known as
THE RIGHT TO KNOW LAW

16. THE RIGHT TO KNOW LAW
You have the right to know what chemicals you are working with in a working environment.
Light alcohol on fire vs. water

17. MSDS Identifies manufacturer Gives chemical and physical properties
MSDS stands for = Material Safety Data sheet
Identifies manufacturer
Gives chemical and physical properties
Indicates fire and explosion hazard
Identifies health hazard
Gives reactivity data
Indicates storage and handling procedures
Supplies first aid information
Details disposal and cleanup methods
MSDS sheets online

19. TYPES OF CHEMICAL EXPOSURE
What does Exposure mean?
Two types of chemical exposure:
Acute
Chronic

20. ACUTE EXPOSURE ACUTE REACTIONS
Exposure to large amount of chemicals in a short period of time.
ACUTE REACTIONS
A reaction that happens right away or
within minutes or hours.
(Burns, rashes, nausea)

21. CHRONIC EXPOSURE CHRONIC REACTIONS
Exposure to small amounts of a chemical over long periods of time
CHRONIC REACTIONS
A reaction that occurs or builds up over
a long period of time
(smokers hack)

22. CHRONIC HEALTH EFFECTS
Cancer
Respiratory problems
Birth defects
Mutations

23. WHY DO WE NEED TO KNOW ABOUT CHEMICAL HAZARDS ?
To protect yourself
To protect others
To protect our environment
Each year millions of Americans are exposed to chemicals. It is up to each of us to protect ourselves our environment and each other.
