OOPS! Preventing Human Error
Priority Number One
Teacher Sheet
Objective
To become familiar with the Material Safety and Data Sheets (MSDS) and safety
precautions for working with chemicals.
Background
Safety is the number one priority in a high school chemistry classroom. The students
must be aware of proper handling of chemicals and equipment for the prevention of
accidents. If an accident should arise, it is important that everyone in the classroom
knows where safety equipment, such as the fire extinguisher and safety shower, is
located.
Not only is being able to read a MSDS important for a science classroom, but today,
more and more companies pride themselves on the number of workdays without a
reportable accident. This is the result of improved safety plans and safety training.
Guidelines
Every chemical that the school has should have an MSDS on file. These should be
located in a notebook easily accessible to teachers and students. Each classroom that
contains chemicals should have a MSDS file in the room. MSDS individual chemical
sheets can be reproduced and provided to the students or the students can locate the
MSDS sheets at several web sites. Two that are student friendly are listed below:

Students could make a poster for this or put the information on the chemical in a
spreadsheet format.
Commonly used high school chemicals that students may wish to choose from:
Hydrochloric acid Acetic acid Hydrogen peroxide Barium hydroxide
Nitric acid Acetone Phenolphthalein Salicylic acid
Sulfuric acid Calcium chloride Iron III nitrate Silver nitrate
Ammonia Copper II sulfate Sodium hydroxide Zinc sulfate

OOPS! Preventing Human Error
Priority Number One
Student Sheet
Objective
To become familiar with the Material Safety and Data Sheets (MSDS) and safety
precautions for working with chemicals.
Materials
鈥? MSDS for a particular chemical
鈥? Poster board
鈥? Markers
Procedure
1. Draw a diagram of the classroom. On your diagram identify the location of the
following items:
o Fire extinguisher
o Safety shower
o Eye wash station
o Glass disposal
o Fire blanket
2. Using the MSDS on your chemical, make a poster based on your chemical, including
the following items:
o Name of chemical
o Molecular formula
o Molecular weight
o Physical state at room temperature (gas, liquid, or solid)
o Color and odor
o Reactivity
o Conditions to avoid
o Spill/leak measures
o Health hazards
o First aid measures
o Handling and storage
o Chemical stability
o Proper disposal of the chemical; if a certain organization or company needs to be
contacted, the student will need to have the address and phone number of the
nearest facility
o Personal protection equipment that needs to be used when handling the chemical
(type of eyewear, gloves, etc.)
