Environmental protection,
Occupational Safety and Health
are the Responsibility
of all staff, students and
collaborators.
OBJECTIVES
To lay down general safety specifications
and requirements
To provide primary information for various
safety issues
To promote awareness on safety
Read MSDS &
understand the hazards
before handling
Definition:
MSDS contains information on
chemical identification, composition,
and physical properties along with
health, physical, environment
hazards and disposal consideration.

What is a Material Safety Data Sheet (MSDS)?
A Material Safety Data Sheet (MSDS) is designed to
provide both workers and emergency personnel with
the proper procedures for handling or working with a
particular substance. MSDS's include information such
as physical data (melting point, boiling point, flash
point etc.), toxicity, health effects, first aid, reactivity,
storage, disposal, protective equipment, and spill/leak
procedures. These are of particular use if a spill or
other accident occurs.
Laboratory
Safety Rules
Hypothesize: what do you believe to be the 5
greatest dangers in a science lab – list
them in ascending order
Why is Lab
Safety
important?


Lab safety is a
major aspect of
every lab based
science class.
Lab safety rules
and symbols are
needed so that
students do not
injure themselves
or their classmates.



Hands-on experiences are essential to
learning in science class, but safety must be
the first concern!
The following rules exist for your safety.
These rules help to prevent accidents in the
lab and allow for more efficient work to occur.
Lab Safety Rules





1. Always follow the teacher’s



Report all accidents immediately, no
matter how small.
This includes broken glass, cuts and
