Lab Safety
and
WHMIS Education
Lab Safety
• As a senior student Lab Safety should
not be new to you. However let’s review
some key features.
– Always keep safety in mind
•
•
•
•
•
Safety equipment
Personal Protective Equipment
Lab Equipment
Lab Procedures
Chemical Handling
Safety Equipment
• Please make sure that you know where
the safety equipment is located in the
classroom and know how to use it.
•
•
•
•
Eye Wash
Fire Blanket
First Aid Kit
Fire Extinguisher
Personal Protective Equipment
• Check labs before hand to ensure that
you are wearing the proper Personal
Protective Equipment (PPE).
• Safety Goggles
• Safety Aprons
• Latex Gloves
Lab Equipment
• Ensure that you are using all Lab
equipment properly and in a safe
manor.
• DO NOT USE BROKEN GLASSWARE
• Use equipment for the purposes that it was
designed for
• Be aware of your surroundings
• Watch sharp objects.
• Be careful near hot equipment (flames, glass, etc.)
• When handling hot objects use proper tongs/gloves
• All broken glass goes into the glass bin, please
inform the teacher.
Lab Procedures
• When working with equipment be sure to
follow proper handling procedures.
• Focusing Microscopes
• Lighting Bunsen Burners
• Read and Follow all lab procedures before
and during lab
• Do not be afraid to ask for help if confused or
unsure how to use a piece of equipment
Chemical Handling
• Handel all chemicals as if they are
dangerous.
• If unsure of handling procedure please refer to
text book, MSDS, or the teacher
• Do not taste
• When smelling waft towards you (do not smell
directly)
• In case of spill please notify the teacher
• Follow directions for proper disposal of
chemical waste
WHMIS
• WHMIS stands for Workplace Hazardous
Material Information System. It not only
identifies harmful chemicals but also lets
people know how to work with them.
• Three essential parts;
• WHMIS Labeling
• MSDS
• Education and Training
WHMIS Labeling
• One of the most recognized parts of the
labeling system is the WHMIS symbols
which are recognized world wide.
WHMIS Labeling
CLASS A: Compressed Gas
This class includes compressed gases, dissolved gases, and gases liquefied by
compression or refrigeration. If the container is greater than 40 psi, the gas is a
Class A product. The cylinder may explode if exposed to heat or to physical
shock (Dropped).
Examples: Oxygen and Acetylene in cylinders for welding, propane
WHMIS Labeling
• One of the most recognized parts of the
labeling system is the WHMIS symbols which
are recognized world wide.
WHMIS Labeling
CLASS B: Flammable and Combustible Material
This class includes solids, liquids, and gases capable of catching fire in the presence of a
spark or open flame under normal working conditions. Class B has six divisions:
Division 1: Flammable Gasses
Division 2: Flammable Liquids
Division 4: Flammable Solids
Division 5: Flammable Aerosols
Division 6: Reactive Flammable Materials
WHMIS Labeling
• One of the most recognized parts of the
labeling system is the WHMIS symbols which
are recognized world wide.
WHMIS Labeling
CLASS C: Oxidizing Materials
These materials increase the risk of fire if they come in contact with flammable or
combustible materials.
Examples: perchloric acid, hydrogen peroxide, permanganates, compressed
oxygen
WHMIS Labeling
• One of the most recognized parts of the
labeling system is the WHMIS symbols which
are recognized world wide.
WHMIS Labeling
CLASS D: Division 1
Materials Causing Immediate and Serious Toxic Effects
These materials can cause death or immediate injury when a person is exposed
to small amounts.
Examples: sodium cyanide, hydrogen sulphide
WHMIS Labeling
• One of the most recognized parts of the
labeling system is the WHMIS symbols which
are recognized world wide.
WHMIS Labeling
CLASS D: Division 2
Materials Causing Other Toxic Effects
These materials can cause life-threatening and serious long-term health problems
as well as less severe but immediate reactions in a person who is repeatedly
exposed to small amounts. Health problems include immediate skin or eye
irritation, allergic sensitization, cancer, serious impairments of specific body
organs and systems, and reproductive problems.
Examples: xylene, asbestos, isocyanines
WHMIS Labeling
• One of the most recognized parts of the
labeling system is the WHMIS symbols which
are recognized world wide.
WHMIS Labeling
CLASS D: Division 3
Biohazardous Infectious Materials
These materials contain harmful micro-organisms that have been classified into
Risk Groups 2, 3, and 4 as determined by the World Health organization or the
Medical Research Council of Canada.
Examples: cultures or diagnostic specimens containing salmonella bacteria or the
hepatitis B virus
WHMIS Labeling
• One of the most recognized parts of the
labeling system is the WHMIS symbols which
are recognized world wide.
WHMIS Labeling
CLASS E: Corrosive Materials
This class includes caustic and acid materials that can destroy skin or eat through
metals.
Examples: sodium hydroxide, hydrochloric acid, nitric acid
WHMIS Labeling
• One of the most recognized parts of the
labeling system is the WHMIS symbols which
are recognized world wide.
WHMIS Labeling
CLASS F: Dangerously Reactive
These products may self-react dangerously (for example, they may explode) upon
standing or when exposed to physical shock or to increased pressure or
temperature, or they emit toxic gases when exposed to water.
Examples: plastic monomers such as butadiene; some cyanides
WHMIS Labeling
• One of the most recognized parts of the
labeling system is the WHMIS symbols which
are recognized world wide.
WHMIS Labeling
• The WHMIS symbols should not be confused
with those used in the Household Hazardous
Products System;

DANGER! EXTREMELY FLAMMABLE. IRRITATES EYES.
PRECAUTIONS: Keep away from heat, sparks, and
flames. Ground containers when pouring. Avoid
breathing vapours or mists. Avoid eye contact. Avoid
prolonged or repeated contact with skin. Wear splashproof safety goggles or faceshield and butyl rubber
gloves. If acetone is present in concentrations greater
than 250 ppm, wear a NIOSH-approved respirator with
an organic vapour cartridge. Use with adequate
ventilation, especially in enclosed areas. Store in a cool, well
ventilated area, away from incompatibles. FIRST AID: In case of
contact with eyes, immediately flush eyes with lots of running water
for 15 minutes, lifting the upper and lower eyelids occasionally. Get
medical attention immediately. In case of contact with skin,
immediately wash skin with lots of soap and water. Remove
contaminated clothing and shoes. Get medical attention if irritation
persists after washing. Wash clothing before reuse. If inhaled,
remove subject to fresh air. Give artificial respiration if not breathing.
Get medical attention immediately. If swallowed, contact the Poison
Control Centre. Get medical attention immediately. Do not give
anything by mouth to an unconscious or convulsing person.
ATTENTION! THIS CONTAINER IS HAZARDOUS WHEN EMPTY.
ALL LABELLED HAZARD PRECAUTIONS MUST BE OBSERVED.

MSDS
• MSDS stands for Material Safety Data
Sheets.
• For every chemical held with in a
workplace there should be an MSDS.
• MSDS should be kept alphabetically
and in a binder.
• Many workplaces are going to a
computer database of MSDS
MSDS
•
MSDS are typically Split into 9 sections;

Education and Training
• It is the responsibility of the Employer to
provide safety Education and Training
including WHMIS
• WHMIS education is learning how WHMIS
works, what the symbols are, what an
MSDS is, etc.
• WHMIS training is hands-on, job specific
training on how WHMIS is implemented
into the workplace, and how to work safely
with hazardous materials.
