When working with chemicals, you will need to
wear safety goggles. Regular eyeglasses do not
give adequate protection.
Many chemicals require the use of gloves. Check
your MSDS or lab write up for the right equipment.
8
Many chemicals can stain or dissolve fabrics.
Aprons should be worn to protect your clothing.
Check your lab write-up or MSDS to determine if
tongs are needed to handle containers of
chemicals.

31.Never touch, taste, or smell any chemical.
Dont taste papers such as pH or litmus or any
test solutions such as Benedicts solution. If
the instructions include to note the fumes in an
experiment, always gently wave your hand over the
opening of a container and direct the fumes
toward your nose. This is called wafting. 32.Be
sure to use the right chemical. Read the label
twice.
10
33.Do not return excess chemicals back to the
reagent bottles or to their original
containers. Do not use the same spatula to
remove chemicals from two containers. Each
container should have a different
spatula. Replace all stoppers and caps on the
bottle as soon as you are finished using
it. 38.Keep all chemicals in the lab.
11

• 16.Keep hands away from face, eyes, and body
  while using solutions
• 15.Label and date all containers that you use to
  hold chemicals.
• Use a pencil to mark the white patch found on
  many pieces of glassware. Erase the marks when
  you are finished.
• If there is no white patch, a black china marker
  should be used.

12
36.Acids and bases react easily with other
substances. If you get an acid or a base on your
clothes or your skin, begin rinsing and notify
your teacher immediately. Pour acids and bases
over the sink, not the counter top. If you need
to combine an acid or a base with water, always
add acids and bases to water NOT the other way
around.
13
Working with
Glassware
41-45.Never use broken or chipped glassware.
Dispose of broken glassware in the designated
location. 48.Do not put hot glassware in cold
water.
14
Electrical Hazard
15
44, 46. Do not leave electrical cords out where
someone might trip over them. Keep cords away
from heat and water. Never touch electrical
equipment or cords with wet hands. Turn off all
equipment when you are finished with the
investigation. Grasp the plug when you
disconnect your equipment. Do not pull on the
cord.
16
Heat or Fire
17
When working with heat or fire, you will need to
wear safety goggles.
To move hot objects you will need to use the
right tongs. Different types of containers use
different sets of tongs
18
The laboratory gas burner is designed to heat a
small area with a hot flame. This makes the
burner useful for heating glassware such as test
tubes and beakers.
19
Never use a heat source without wearing safety
goggles. 49.If you have long hair make sure it is
pulled away from your face. Maintain a clean
work area and keep all material away from
flames. Never reach across a flame. Never
point a heated container at anyone. Keep all
materials away from heat sources unless
specifically instructed to heat it.
20

• 50.Never leave a flame unattended when the
  burner is not needed, turn it off.
• 51.Never heat a liquid in a closed container.
  The expanding gases produced may blow the
  container apart, harming you or others.
• 52-54.Never pick up a container that has been
  heated without first holding the back of your
  hand near it.
• Always use a mitt, clamp or tongs when handling
  hot containers.
• REMEMBER Hot glassware looks the same as cool
  glassware.
