Hazard and Risk -- What's the difference?
Danger et risque – Quelle est la difference?
• https://www.youtube.com/watch?v=_GwVTdsnN1E

A hazard is any source of potential damage
or harm to an individual’s health or life
under certain conditions.
Risk is the chance or probability of a person
being harmed or experiencing an adverse
health effect if exposed to a hazard.

Action
Hazard and Risk -- What's the difference?
Danger et risque – Quelle est la difference?

Risks can be reduced by
taking measures to minimize
or control the hazard.

How to do a Risk Assessment?
Risk assessment template : Determine hazards and evaluate risks
• Do it with your colleagues
• Agree it with your supervisor
What are the
hazards?
Who might
be harmed
and how?
What are you
already doing
to control the
risks?
What further action
do you need to take
to control the risks?
Who needs
to carry out
the action?
When is the
action
needed by?
Done

3. Minimize (or control) the risks of the
hazards/Minimiser (ou contrôler) les risques du
danger
Use the safe practices
• Know details and location of the vital
Laboratory Information.
• Labeling : It is important to know as much
about a chemical as possible.
25

3. Minimize (or control) the risks of the
hazards/Minimiser (ou contrôler) les risques du
danger
Signs and Labeling/Signes et étiquettes
• The label should describe what
the content is and also any
precautions.
Escherichia coli
Precautions:
Must use Eye protection, lab coat, gloves
Only use under BSC
26
Signs are a way of communicating important
information. It is a way to heighten awareness about
hazards that exist.

3. Minimize (or control) the risks of the hazards
Know the properties of chemicals and biological
agents before you use or transport them
• Toxicity
• Flammability
• Reactivity/Incompatibilities
• Corrosive
• Unstable
• Radioactive
• ….

Safety Equipment/Equipement de Protection
Collective (EPC)
Fume hoods/Sorbonnes et hottes
Use Properly:
• keep sashes down
• don’t store flammable liquids,
equipment in hood
• limit traffic behind you
It is important to know when this equipment is to be used
and how to properly use it. 31

Safety Equipment/Equipement de Protection
Collective (EPC)
Chemical Storage/armoires chimiques
• Ensure that all chemicals are stored according to compatibility. Acids are
incompatible with bases, flammable solvents, oxidizers
• Water reactive materials should be stored separately.
• All chemical products must be dated when opened
The storage area and cabinets should be labeled to identify the hazardous nature of
the products stored within.
Food containers MUST NEVER BE USED for chemical storage.

What’s Wrong With These Statements?
• Hal says that his teacher is solely responsible for preventing laboratory
accidents.
• Keshia started the lab activity before reading it through completely.
• Ricardo decided to do a lab activity that he read about in a library book
before the teacher came into the classroom.
• Stephanie says that the safety goggles mess up her hair and give her
raccoon eyes. She refuses to wear them.
• Barbie and Ken accidentally break a beaker full of some chemical.
Instead of risking getting in trouble they quickly clean up the mess with
paper towel and throw it in the garbage.
