This document provides safety guidelines and rules for students to follow when conducting experiments in a laboratory. It emphasizes the importance of being prepared before starting an experiment by ensuring a clean work area and wearing proper protective equipment like goggles and closed-toe shoes. When handling chemicals, students are instructed to waft rather than smell chemicals directly, check material safety data sheets, and properly dispose of or store reagents. Key safety tips during experiments include keeping goggles on at all times, not eating/drinking, and being careful with heated materials and flames. The document also identifies what to do in emergency situations and clean-up procedures after finishing experiments.

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

2. Rules in the laboratory
 Rules 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.

3. 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.

4. 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.

5. 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.
 Keep your goggles on at ALL times. Your
eyesight is precious and you can’t have it
back. (No contact lenses)
 Don’t run, jump or roughhouse!

6. During the experiment, cont’d.
 BE CAREFUL with
the lab equipment.
Don’t put
thermometers or
glass tools out where
they can roll off the
table and break.
 Pick up heated
materials using
tongs. DO NOT use
rubber tongs near
open flame.
 Don’t use flammable
substances near
open flame.
 Do not leave burners
unattended, and be
careful about using
too much gas!
 Don’t point a test
tube at yourself, or a
partner.
 Record your data
immediately. Don’t
wait!

7. Emergencies!
 Know where the Fire extinguisher is,
and how to use it.
 Know where the eyewash fountain is,
and how to use it!
 Know where the emergency shower
is, and how to use it!
 You MUST tell your instructor in the
case of any injury.

8. After the Experiment
 Make sure that all substances are
properly disposed of.
 Clean all your glassware carefully and
put it back where you found it.
 The last period should put the
equipment away.
 Clean your work station. Other classes
might be using the same things!
