Wait! Play it Safe!A powerpoint about safety and good sense in the laboratory!

Rules in the laboratoryRules are an important part of

any experiment. You should know them because they…

Teach you how to protect yourself, and others from the hazards in the lab

Help you prepare and conduct your experiment in a reliable fashion

Can save your eyesight, spare you from injury, and help you act quickly in an emergency.

Before you start… Look at your lab area

before you start working. Make sure it is clean and uncluttered. (stools)

Always wear goggles (Send one person up)

Think ahead! Wear closed toed shoes, bring a hair tie!

Pay attention to signs and labels.

Read and re-read the procedure. Make sure you understand.

Working with Chemicals? WAFT chemicals, never smell

them directly. Make sure you double check

the MSDS (Material safety data sheet) on any chemicals you must work with yourself.

Combine only the reagents outlined in the lab proceedure.

If you are combining acid and water, mix ACID with H20, not the other way around!

Consider ALL chemicals dangerous unless you are told otherwise. (even water)

DO NOT dump excess reagents down the sink, unless your instructor tells you to. Never put reagents back in their bottles.

During the experiment…Keep your goggles on at ALL times. Your

eyesight is precious and you can’t have it back. (No contact lenses)

Don’t eat or drink.Only your labsheet or your notebook should be

brought to the experiment table. No backpacks

Pick up heated materials using tongs. DO NOT use rubber tongs near open flame.
