SAFETY IN THE
CHEMISTRY LAB
• What is a Material
Safety Data Sheet
(MSDS)?
• designed to provide
both workers and
emergency
personnel with the
proper procedures
for handling or
working with a
particular
substance.
Material Safety Data
Sheet (MSDS)
• MSDS's include any safety issue such
as physical data (melting point,
boiling point, flash point etc.),
toxicity, health effects, first aid,
reactivity, storage, disposal,
protective equipment, andspill/leak
procedures.
• These are of particular use if a spill
or other accident occurs.
Hazard Identification
label
• Summarizes
risks
related to
health,
flammabilit
y and
reactivity.
• A number
scale
indicates
the level
of risk.
MSDS
• Every company that manufactures or
distributes hazardous chemicals in
the United States must prepare a
Material Safety Data Sheet (MSDS).
• Mandated by the Occupational
Safety and Health Administration
(OSHA) in their Hazard
Communications Standard 29CFR
1910.1200.
• This standard is commonly referred
to as the Right-To-Know Law.
What items or formats are
required on an MSDS?
• ALL U.S. MSDS's must includde the
items found on OSHA’s Form 17.
• You can include more items than
OSHA requires.
• The American National Standards
Institute (ANSI) has a 16-part
standard format which encompasses
the areas given in the OSHA
standard and adds a few more such
as toxicology.
• In fact, OSHA now recommends
using the ANSI format!
MSDS QUIZ
• MSDS sheets must be written in:
• A OSHA Form 174 format
• B ANSI format
• C EPA format
• D Any format, but must contain the
information found in OSHA Form
174.
• E Any format; there are no specific
requirements for content.
OSHA’s Form 17
• Chemical Identity
• Section I. Manufacturer's Name and
Contact Information
