Lab Safety

• As a senior student Lab Safety should not be new
  to you. However lets review some key features.
• Always keep safety in mind
• Safety equipment
• Personal Protective Equipment
• Lab Equipment
• Lab Procedures
• Chemical Handling

3
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

4
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

5
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.

6
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

7
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

8
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

9
WHMIS Labeling

• One of the most recognized parts of the labeling
  system is the WHMIS symbols which are recognized
  world wide.

10
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
11
WHMIS Labeling

• One of the most recognized parts of the labeling
  system is the WHMIS symbols which are recognized
  world wide.

12
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
13
WHMIS Labeling

• One of the most recognized parts of the labeling
  system is the WHMIS symbols which are recognized
  world wide.

14
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
15
WHMIS Labeling

• One of the most recognized parts of the labeling
  system is the WHMIS symbols which are recognized
  world wide.

16
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
17
WHMIS Labeling

• One of the most recognized parts of the labeling
  system is the WHMIS symbols which are recognized
  world wide.

18
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
19
WHMIS Labeling

• One of the most recognized parts of the labeling
  system is the WHMIS symbols which are recognized
  world wide.

20
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
21
WHMIS Labeling

• One of the most recognized parts of the labeling
  system is the WHMIS symbols which are recognized
  world wide.

22
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
23
WHMIS Labeling

• One of the most recognized parts of the labeling
  system is the WHMIS symbols which are recognized
  world wide.

24
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
25
WHMIS Labeling

• One of the most recognized parts of the labeling
  system is the WHMIS symbols which are recognized
  world wide.

26
WHMIS Labeling

• The WHMIS symbols should not be confused with
  those used in the Household Hazardous Products
  System

27
WHMIS Labeling

• WHMIS product labels are used to inform the
  worker of dangers.
• They must contain the following information
  within a cross-hatched border.
• Product Identifier
• Hazard Symbol
• Risk phrases
• Precautionary statements
• First Aid measures
• Supplier identification
• Reference to MSDS

ACETONE ACÉTONE
See Material Safety Data Sheet for this product
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 splash- proof 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

30
MSDS

• MSDS are typically Split into 9 sections
• Product Information
• Hazardous Ingredients
• Physical Data
• Fire and Explosion Hazard
• Reactivity Data
• Toxicological Properties
• Preventative Measures (PPE)
• First Aid Measures
• Preparation Information

31
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.
