WHMIS is
A Canada-wide system designed to give employers
and workers information about hazardous materials
used in the workplace. WHMIS standards are
coordinated between both Federal and Provincial
governments. Manitoba Workplace Safety and
Health Act and Regulations sets the WHMIS
requirements.
4
WHMIS has 3 Main Parts

• Labels provide information about the hazards of
  the product
• Material Safety Data Sheets (MSDS) provide
  further detailed information about the hazards
  associated with the product
• Education how to use the information provided
  in the MSDS and on the Label

5
The GOAL is

• Identify 6 Classes of Controlled Products
• Understand the Main Hazards associated with each
  class
• Recognize and understand the two types of WHMIS
  labels
• Understand how to use Material Safety Data Sheets

6
A Controlled Product is
Any substance or material which meets any of the
criteria for inclusion in one or more of the six
WHMIS Hazard Classes as defined in the Federal
Controlled Product Regulation. Under WHMIS ,
there is no comprehensive list of controlled
products but only a list of hazard criteria.
7
WHMIS Does Not Apply

• When WHMIS does not apply there may be another
  Act or regulation that does.
• WHMIS does not apply to controlled products that
  are
• Wood or a product made of wood
• Tobacco or a product made of tobacco
• A manufactured item that will not release
  chemicals
• Products transported under the Transportation of
  
• Dangerous Goods Act

8
When WHMIS Does Not Apply

• WHMIS does not apply to products covered by
• Explosives Act
• Food and Drugs Act
• Pest Control Products Act

provides this service for PTSD
36
MSDS
Information Provided
Product Information This section identifies
product name, manufacturer and suppliers names,
addresses, and emergency phone numbers, and the
intended use of the product. Hazardous
Ingredients This section lists all potentially
hazardous ingredients, with the approximate
amount (percent), and toxicity data for the
individual ingredients. Information regarding the
LD50 and LC50 (the amount of a chemical that is
expected to kill 50 of a test animal population
within a specified time) will also be given. The
lower the value the greater the poisoning
potential.
37
MSDS
Information Provided
Physical Data Provides information on the
physical and chemical properties such as odour,
boiling point, and vapour density.   Fire or
Explosion Hazard Data Provides the conditions
under which the product may catch fire or
explode, as well as information for developing
strategies and procedures to deal with fire and
explosion hazards. First Aid Measures Lists the
procedures for emergency first aid.
38
MSDS
Information Provided
Reactivity Data Provides information regarding
stability, self-reactivity, hazardous
decomposition products, and conditions to avoid
when using the product.   Toxicological
Properties Identifies how the substance can enter
the body and the possible health effects from
short term (acute) exposures such as irritation,
sensitization and long-term (chronic) such as
liver or kidney damage, sensitization, cancer, or
reproductive effects. Known exposure limits will
also be given.
39
MSDS
Information Provided
Preventative Measures Provides preventive
measures you can take to protect yourself from
exposure including extra ventilation, personal
protective equipment (PPE), safe use, handling,
storage, disposal, transport, and spill
control. Preparation information Indicated who
was responsible for preparation and date of
preparation of MSDS. It is 3 years from this date
when the MSDS needs to be renewed. Information
may be labeled as Trade Secret if a claim has
been filed. The information is released to
medical professionals in case of emergency.

MSDS

• Location, Location, Location
• All staff are required to know the location of
  the MSDS book
• All staff that use or work in close proximity to
  chemicals are required to know how to use WellNet
  to access MSDS information via the PTSD website.

45
Hazardous Waste Disposal Procedures

• Every year the School Division coordinates a
  hazardous waste pick up with Miller
  Environmental.
• Hazardous waste pick up occurs every June.
• Hazardous waste labels and Miller Environmental
  Hazardous Waste Inventory sheets are available on
  the PTSD website.
• Science teachers should incorporate waste
  disposal into lab procedures or experiments
• Reminder NO disposal of Hazardous Waste is
  permitted down the drain (unless it has been
  neutralized and pH verified) or regular trash
  can.
• Remember that your end point is someones
  starting pointRefer to the PTSD Workplace SH
  webpage for details

46
Spill Clean-up
Chemical or Biological

• If a spill occurs that poses an immediate risk to
  people, or if someone is injured it is an
  EMERGENCY
• Minor spills should be cleaned up by trained
  staff
• Spills must never be cleaned up by untrained
  staff
• Under no circumstance shall caretakers be
  instructed to clean up any lab spills
• The best time to learn about and practice
  cleaning up a spill is before it happens read
  the MSDS
• SH Officer is also available to assist with the
  cleanup of spills beyond the capabilities of
  available staff Information on spills cleanup
  can be found on the PTSD Workplace SH website

47
Chemical Storage
General Chemical Organization

• Organize by compatibility not alphabetically
• Separate each compatible group
• In separate cabinets or on separate shelves
• Or in secondary containers in same cabinet or
  shelf
• Make sure all containers are properly closed
• Containers must be labeled and tightly capped

48
Chemical Storage
General Chemical Organization
Flammables Store in flammable storage cabinets
Bases Store separately
Oxidizers Store separately
Acids Store in corrosive resistant acid cabinet EXCEPT chromic, nitric, and perchloric acids which should be stored separately Glacial acetic acid should be stored as a flammable
49
Chemical Storage
Potentially Explosive Chemicals

• Picric Acid and Nitro Compounds
• Dry picric acid may explode if subjected to
  heat, shock, or friction (opening the lid)
• Picric acid must be stored under wet.
• Some nitro compounds may have similar
  requirements
•  
• Peroxide Forming Compounds
• Example ethers, dioxanes, sodium amide
• Peroxide formation may be initiated by light or
  air
• Peroxides are prone to explosive decomposition
  when subjected to heat, shock, or friction
  (opening the lid)
• Evaluate the conditions of these chemicals
  regularly
• Refer to MSDS for storage and handling
  requirements
