may be potentially dangerous
Describe ways in which potentially dangerous situations may be corrected
Use common safety signs and symbols
Formulate safety rules for selected working environments
Apply safety rules to selected working environments
Predict the consequences that may result from not following safety rules
Evaluate the environmental impact relating to disposal of selected substances
Safety precautions in exploring the environment
There are many potential dangers (hazards) in our homes,
school and the area in which we live.
To be safe, we need to be aware of the dangers and know how
to behave and take precautions so that we can avoid
accidents.

Safety in Science
There are many safety hazards in a science laboratory (lab) including many types
of chemical. Different chemicals pose different risks.
When you are in the lab, it is important to know the rules of conduct so that you
are always safe when carrying out activities.
General Lab Rules
1. Enter the laboratory ONLY with the teacher’s
PERMISSION.
2. Place all bags and books on the designated shelves to
keep pathways clear.
3. NO food or drink should be brought into the lab
4. NO playing in the lab (always walk in the lab)
5. Wear safety gear when working in the lab e.g lab coat
General Lab Rules
6. Do NOT taste or smell chemicals unless instructed to do so by
your teacher
7. Do NOT attempt unauthorised experiments
8. Read ALL instructions carefully and ask for clarification as
required
9. Report immediately any broken or damaged equipment
General Lab Rules
10. Handle apparatus and materials both carefully and
correctly. Do not hold apparatus with you bare hands.
11. Do NOT remove apparatus or chemicals from the lab
12. Keep your work area clean and uncluttered and dispose of
waste properly
13. Wash hands thoroughly before leaving the lab or
experimenting.
When accidents occur
● Report all accidents, breakages or spillages to your teacher
immediately
● If a chemical gets into your mouth, spit it into a container and
rinse your mouth as quickly as possible with plenty of water and
report the incident to the teacher
● If any chemical falls on your body or clothing, rinse the area
thoroughly with water and report the incident to the teacher.

Safety Symbols
Many of the chemicals used in the laboratory, and
sometimes at home, are dangerous.
The bottles containing these chemicals have caution labels
on them. These labels are universal.
Sometimes caution labels are given a colour code:
Red --- dangerous
Yellow --- hazardous
Green ---- safe
Safety in the Workplace
Safety must never be taken for granted. It is very important that
workers are provided with an environment which will not make
them sick or put them at risk of getting an injury.
The Health and Safety Laws in Jamaica states that employers
should display important safety signs on the work site and
provide workers with the necessary gear to protect them while
they are working.

Proper Waste Disposal
Hazardous waste is any kind of waste that presents a health concern to humans when it is
created. It can come in many forms, and, it can be created from all kinds of human activities,
Many hazardous wastes create an immediate health hazard to anyone who may come into
contact with them. This can be a chemical byproduct or a contaminated solid, or anything in
between. For this reason, proper and swift disposal is a must. Hazardous wastes can cause
harm to the environment, as well.
Improper disposal of hazardous waste can even affect humans via drinking water and food
consumption. If a hazardous waste is not properly disposed, it can easily enter the environment
at an undesirable rate.
