HEALTH HAZARDSSlide5
Chemical and physical health hazards
Chemical and physical hazards are materials that in the event of exposure may result in serious health problems, such as:
Burns to your skin or eyes (upon contact)
Allergic reactions
Kidney or lung damage
Biological diseases
Sterility
CancerSlide6
WHMIS Hazard Symbols
There are 6 categories and 8 WHMIS hazard symbols used for industrial products:
Compressed Gas
Flammable and Combustible Material
Oxidizing Material
Poisons and Toxic Materials
Immediately Poisonous Material
Material Causing Other Toxic Effects
Bio-hazardous Infectious Material
Corrosive Material
Dangerously Reactive MaterialSlide7
Class A: Compressed Gas
Materials under Class A are held under pressure and can explode if heated or subjected to physical shock.
Handling Tips:
The container must be secured and held up-right when stored or moved.
The cap must be kept on when not in use.
If the container has a regulator, the regulator must be disconnected before it is moved.
To avoid impact forces the container should never be dropped, dragged, rolled
or
punctured.
Always keep containers away
from heat and
sparks.
Never use grease/oil on any valve on the container.
Examples
Oxygen
Fire ExtinguisherSlide8
Class B: Flammable and Combustible Material
Materials under Class B can burn and/or burst into flames very easily and suddenly when exposed to spark or open flame.
Handling Tips:
Always keep containers away from heat and flames.
Always keep containers sealed tightly to avoid accidental release into the environment.
Always clean up spills immediately and dispose of clean up materials in a metal container.
Never store near oxidizing or reactive materials.
Examples
Isopropyl Alcohol
FormaldehydeSlide9
Class C: Oxidizing Material
Materials under Class C increase the risk of a fire and/or explosion in the presence of flammable or combustible materials.
Handling Tips:
Always keep containers away from heat and flames.
Always keep containers sealed tightly to avoid accidental release into the environment.
Always store containers away from flammable/combustible and reactive materials.
Examples
Bleach
Hydrogen Peroxide
OxygenSlide10
Class D

have the potential to cause immediate and permanent damage.
These materials may cause death when exposed to small amounts.
Handling Tips:
Always use in a well ventilated area.
Always follow proper hygiene protocols after working with these materials; especially before eating, drinking or smoking.
Always wear proper protective equipment.
Never wear your work clothes home.
ExamplesFormaldehyde

ExamplesRabies
LeptospirosisToxoplasmosisSlide13
Class E: Corrosive Material
Materials under Class E have the potential to cause severe irritation and/or tissue damage under the following circumstances: upon contact with the skin or eyes, when inhaled, when ingested.
Some of the materials under Class E also have the ability to eat through metal.
Handling Tips:
If exposed, immediately flush out the skin or eyes for at least 15 minutes and seek professional medical care if symptoms do not resolve quickly.
Always use in a well ventilated area.
Always
follow proper hygiene protocols after working with these materials; especially before eating, drinking or smoking.
Always wear proper protective
equipment – a cartridge or supplied air respirator may be required.
Never wear your work clothes home.
Examples
Bleach
Peroxigard
Hydrogen
PeroxideSlide14
Class F: Dangerously Reactive Material
Materials under Class F are very unstable and have the potential to self-react dangerously upon standing or if there is a change in temperature, pressure, physical shock or exposure to air/water.
Handling Tips:
Always keep these materials away from any source of heat.
Always dispose of old chemicals as soon as possible.
Always handle with care, DO NOT DROP.
Never mix these materials with other chemicals.
Never mix these materials with water.
Examples
Ethylene
Oxide
ChlorineSlide15
Consumer Product Warning Symbols
Consumer Warning Labels are used on products that can be found on store shelves.
These symbols are similar to the WHMIS industrial symbols with the exception of the outer boarder.
Each outer border designates the product’s level of danger

MEANS OF EXPOSURESlide21
Acute vs Chronic Effects
Acute Effect
Exposure causes
i
mmediate harm to your health (inside and/or out).
The effects of exposure can occur within a few minutes, a few hours or a few days.
Chronic Effect
Exposure causes harm to your health over a longer period of time.
The effects of exposure can occur months or years after the exposure occurred.Slide22
Measuring Acute Toxicity
Lethal Dose 50 (LD
50
)
The amount of material that causes death in 50% of the test patients when it is introduced into their body by a specified route.
Usually method of exposure is ingestion or skin absorption
It is usually measured in mg/kg or mL/kg of body weight
Higher LD
50
= Lower toxicity
Lower LD
50
= Higher toxicitySlide23
Measuring Acute Toxicity
(continued)
Lethal
Concentration
50 (
LC
50
)
The airborne concentration of the substance
that causes death in 50% of the test patients
in a given time frame.
Usually
expose patients for 4 hours.It is usually measured in mg/kg or mL/kg of body weightHigher LC50 = Lower toxicityLower
LC50 = Higher toxicitySlide24
Routes of Entry
INHALATION
ABSORPTION
INJECTION
INGESTION
MOST
COMMON
LEAST COMMON
Inhalation
can cause more harm to the body than any other route of entry.
Absorption allows for direct access to the blood stream; therefore,
can cause damage externally and internally.
Injection is when a material
is f
orced into the body;
for example, an injection.
Ingestion is
an accidental form of exposure.
It is easily preventable following proper hygiene protocols.

Workplace Label
A
workplace label must be used for hazardous material
when:
It is transferred to a secondary container (for example: isopropyl alcohol, hydrogen peroxide, peroxigard)
The original (supplier) label is missing or damaged
DO NOT USE ANY CHEMICAL MATERIAL THAT IS NOT LABELLED.Slide28

Material Safety Data Sheets (MSDS)
A Material Safety Data Sheet is a document that provides detailed health and safety information specific to the material.
The content of the MSDS is legislated by WHMIS and includes 9 sections. Every section must be completed for every hazardous material. If the information is unavailable or
inapplicable
for a particular product, then it must be stated in the MSDS
.
The supplier must update the MSDS every 3 years or within 90 days of a change to the product.Slide31

Personal Protective Equipment (PPE)
PPE is necessary when engineering and/or administrative controls cannot completely remove the hazard to workers.
The purpose of PPE Is to minimize the exposure to hazardous materials in the workplace.
Employers are responsible for:
Supplying appropriate PPE
Ensuring PPE is in good working order
Providing training to all workers on when and how to use the PPESlide36

WHMIS AFTER GHSSlide38
Globally Harmonized System (GHS)
The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is an international initiative to standardize chemical hazard classification and communication globally. The GHS is anticipated to be
implemented
in Canada in June 2015
.
GHS will not replace WHMIS. WHMIS will be modified to incorporate the GHS elements.Slide39
GHS
(continued)
Under GHS, there
will be new standardized:
Classification Rules
Provides guidance on classifying pure chemicals and mixtures according to its criteria or rules
Label Requirements
Standardized hazard statements
Signal words
Symbols
Precautionary statements may also be required
Safety Data Sheet (SDS) FormatThis document will replace the Material Safety Data Sheet (MSDS) that are currently used under WHMISThey will have
16 sections in a set order, and minimum information prescribedSlide40
GHS
(continued)
Please review the following documents for a full understanding of how the GHS elements will change WHMIS.
