2. Terms To Remember
• HAZCHEM- ( hazardous chemicals) is a
warning plate system used
in Australia, Hong Kong, Malaysia, New
Zealand, India and the United
Kingdom for vehicles
transporting hazardous substances, and
on storage facilities.
3. Terms To Remember
• HAZMAT- Certain dangerous goods
that pose risks even when not being
transported are known as hazardous
materials. Example : hazardous
waste which is waste that has
substantial or potential threats to public
health or the environment.
4. Terms To Remember
• CAS- Chemical Abstracts Service
• GHS-Globally Harmonized System
of Classification and Labelling of
Chemicals. It is a system of hazard
communication for chemical hazards.
GHS was developed by a United Nations
(UN) international team of hazard
communication experts.
7. What Makes a Substance
Hazardous ?
• A material is considered hazardous
if it exhibits any of the following
characteristics:
Toxicity
Reactivity
Ignitability
Corrosivity
Bioaccummulative
11. Materials NOT Included
• Pharmaceutical supplies
• Medical wastes & infectious
materials
• Bulk fuels
• Radioactive materials
• Consumer products
• Food and food additives
12. Scope
• The hazardous materials user--
– Must be familiar with hazards & precautions
– Must be familiar with MSDSs
– Must use and understand hazardous materials
labels
14. Original Container Labels
• Every container of hazardous
materials must be labeled
• Label requirements--
– Identity of material or chemical
– Name & address of manufacturer or
responsible party
– Appropriate hazard warning
– Target organ
15. Secondary Containers
• If hazardous material is dispensed
into an unmarked container, the
container must be labeled with the
following information:
– Identity of material or chemical
– Appropriate hazard warning
17. • Color code identifies the hazard
Blue = Health Hazard
Red = Flammability
Yellow = Reactivity
White = Special Hazard Information
• Numerical rating identifies severity
0 - no hazard, 4 - most severe hazard
Hazardous Material
Information Guide (HMIG)
19. Other Warning Systems
• National Fire Protection Association
(NFPA) 704M diamond
Note: NFPA and DOT labels may NOT be used as
stand-alone labeling systems, but may be used in
conjunction with other labeling systems
• Department of Transportation
(DOT) Labels
20. NFPA Label
• Designed for
emergency personnel
• Does not provide
specific chemical
names or quantities
21. DOT Warning System
• Numbers
• Labels
• Symbols, and
• Classes
to identify the hazardous
material and its hazardous
characteristics
System is used for shipping of
hazardous materials
DOT uses a system of
33. MSDS
• Technical bulletins containing
information about the hazardous
material
• Contain at a minimum the following
information:
– Identity of material
– Hazardous ingredients
– Physical and chemical characteristics
34. MSDS Information
– Physical hazards (fire, explosion,
reactivity)
– Health hazards (routes of entry,
exposure limits, and cancer potential)
– Precautions for safe handling & use
– Emergency first aid procedures
– MSDS preparation date
– Name, address & phone number of
chemical manufacturer, importer,
employer who can provide additional
information
35. MSDS Requirements
• Maintained for every item of
hazardous material in the work
area
• Readily accessible to personnel
who use hazardous materials
• Supervisors provide instruction in
understanding and use
• All personnel trained on dangers
and precautions of hazardous
materials prior to use
37. PERMIT ISSUER
• Ensure PPE available for hazardous
material operations and personnel
trained on use
• Make personnel available to receive
hazardous material training
• Ensure use of approved storage
containers
38. Department Incharge
• Provide control and management of
the hazardous materials
• Maintain MSDS
• Ensure personnel are trained
• Ensure hazardous materials are
labeled when dispensed into other
containers
39. All Staff
• Properly use and handle hazardous
materials
• Report spills
• Label hazardous materials when
dispensed into other containers
41. General Requirements
• Handle incompatible materials in
separate compartments to prevent
mixing
• Never mix incompatible materials
in the same collection containers
• Avoid breathing vapors or dust
from hazardous materials
• Avoid contact with eyes and skin
42. General Requirements
• Do not smoke, eat, or drink where
hazardous materials are used
• Use appropriate PPE
44. Storage
Materials normally thought to be safe may become
hazardous under certain conditions. When
containers leak or are heated, chemical reactions
may result, leading to fire, explosion, or release of
toxic reaction products.
45. Determining Storage
Requirements
• Is the hazardous material
compatible with other chemicals?
• What is the hazard classification?
– Oxidizer, acid, flammable, base, etc.
• Any special storage requirements
on MSDS?
• What is the flash point of the
material?
46. Storage Requirements
• Hazardous materials storage
locations must be posted with
caution signs
• Ensure lockers and cabinets used
for in-use flammable storage
labeled
47. Storage Requirements
• Storage areas must be properly
marked
• Do not transfer material to any
container used for a different
material
– Some materials might be incompatible!
• Store incompatible materials in
separate compartments to prevent
mixing if spilled
48. Storage Requirements
• Store hazardous materials in
compatible containers
– No corrosives in metal drums!
• Stack containers so as to avoid
crushing lower containers, or
access difficulty
• Do not eat, smoke, or drink in
storage locations
49. Storage Requirements
• No open flames or other ignitions
sources in storage areas
• Use only explosion-proof devices in
potentially explosive environments
• Maintain explosion-proof fixtures in
proper condition
• Seal & protect containers against
physical damage
52. IDENTIFYING HAZARDS
Knowledge of the Hazards of
various substance and an
understanding of Physical
Properties can be the difference
between life and death.
53. HAZARD
COMMUNICATION
• This standard was created for you,
because you have a “Right to Know”
about hazardous materials you work
with.
• Do your part and learn all you can
about hazardous materials in your work
areas.
• You know the sources of information-
NOW USE THEM!
