Science 10_Intro to WHMIS & HHPS

WHMIS

A safety system for the workplace.

2

• WHMIS stands for “Workplace

Hazardous Materials Information
System”

• The purpose of WHMIS is to

control the safety labels and
information for chemicals found in
a workplace, this includes schools.

Multiple Choice

What does WHMIS stand for?

• Workplace Hazardous Materials In Schools

• Workplace Hazardous Materials Information Sessions

• Workplace Hazardous Materials Information System

• Workplace Hazards Materials In Schools

Multiple Choice

True or False: If a material does not have a WHMIS symbol it is safe.

• True

• False

Multiple Choice

WHMIS is regulated by the ...

• Federal Government (Canada)

• Provincial Government (Nova Scotia)

• Individual Workplaces

• A government controlled set of

rules that all businesses must
comply with for worker safety.

• We use WHMIS to regulate labels

on chemicals and informative
symbols so safety is consistent
across the country.

How Does WHMIS Work?

Open Ended

Where are WHMIS labels found?

• In WHMIS, pictograms are used to indicate the

danger of a material found in the workplace.
Each pictogram has its own unique danger.

• Dangerously Reactive

Multiple Choice

What does this WHMIS symbol mean?

• Compressed Liquid

• Compressed Cylinder

• Compressed Gas

Multiple Choice

What does this WHMIS symbol mean?

• Health

• Health Risk

• Health Hazard

• In addition to symbols

with generalized
warnings, WHMIS
requires information be
provided to employees
via:
– The Supplier Label

– The Workplace Label

– The SDS

WHMIS Information

8

•Chemicals arrive
with a supplier
label which
contains specific
required
information such
as pictogram,
product
identifier,
supplier, and
signal words.

Supplier Labels

9

• When a chemical is transferred into a new

container, and will be stored, we must place
a label on this new container.

Workplace Labels

10

• A Workplace Label contains a summary of key

information.

• This new

label is the
workplace
label

• Detailed information for

all chemicals is found on
the SDS, Safety Data
Sheet

• All chemicals need to have

a SDS kept in one place,
usually a binder.

Open Ended

Inside each workplace and our school science labs, there should be a binder that contains Safety Data Sheets for each material that is stored. REVIEW SLIDE 16 - IT IS A SAMPLE SDS SHEET. What are three (3) things you can find on an SDS sheet?

HHPS

A safety system for the consumer.

13

• HHPS stands for “Household

Hazardous Products Symbols”

• HHPS was developed for chemicals

used by people in their homes and
provides 2 pieces of information:
– a warning symbol and a
– level of warning

What is HHPS

14

• HHPS is used on very “basic”

chemicals, therefore there are only
4 different symbols.

HHPS Warning Symbols

15

• Materials which are poisonous

can be toxic to your health if
ingested or absorbed into the
body.

HHPS Warning Symbols

16

• Materials which are explosive

expand at high rates, which
can be dangerous and harmful.
They can even rupture a
container.

• Materials which are corrosive

can create chemical reactions
that will dissolve or “eat away”
flesh.

HHPS Warning Symbols

17

• Materials which are flammable

can catch fire very easily, so
keep flames and sparks away.

Multiple Choice

True or False: HHPS was developed for chemicals used by people in their homes

• True

• False

Multiple Choice

How many symbols does HHPS include?

• 3

• 12

• 4

• 16

• Warning symbols are paired with 3

different polygons, representing the
level of danger associated with the
chemical.

HHPS Warning Levels

18

DANGER

CAUTION

WARNING

• The Danger

warning level
represents
the greatest
amount of
danger.

HHPS Warning Levels

19

DANGER
WARNING

• The Warning

warning level
signifies risk
is high, but
not probable.

• The Caution

warning level
represents
the least
amount of
potential
danger.

CAUTION
