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

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

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

Fire Blanket Used to smother out small fires.

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.

Emergency Electric Shut Off Only push this button in case of an electric fire in the classroom. This is not a toy to play with!

Fire Extinguishers Type A, B, C For all kinds of fires: • A- wood, cloth, etc. • B- Chemical • C- Electric Solid sodium phosphate (Na3PO4) chemical powder!

CHEMICAL FUME HOOD

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

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.

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

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.

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

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

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

*Material Safety Data Sheets MSDS forms can be found here at Delcastle High School: Main Office Nurse’s Office Wellness Center Maintenance/Custodians Science classrooms Shops

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

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)

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)

CHRONIC HEALTH EFFECTS Cancer Respiratory problems Birth defects Mutations

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.
