2. HAZARD COMMUNICATION
(HAZCOM)

3. Introduction
We encounter chemical almost every day .
•Filling your vehicle with gasoline .
•Cleaning the bathroom.
•Applying pesticides or insecticides .
•Using solvents or acids at work.
Many chemical can cause injury or illness if not handled
properly .

4. Objective
o To help ensure employer / employees safety when working
with hazardous chemicals.
o They have a right to known about the hazardous chemicals
that they use on the job and how to work safety with those
chemicals .
o Right to know MSDS, Labelling ,first aid and PPE.
("Right to know", in the context of United States workplace and community environmental law, is the
legal principle that the individual has the right to know the chemicals to which they may be exposed
in their daily living.)

5. What is Hazard Communication?
 is designed to maintain a healthy work
environment by increasing employee awareness
about the hazards of the chemicals that they work
with.
 All chemicals are required to have an MSDS sheet
made up for them .
 A Hazard Communication Program is required by
OSHA.

7. OSHA (Occupational Safety and Health
Administration)
•OSHA created the Hazard Communication
Standard.
•OSHA is a government agency under the US
department of labor.
•OSHA officially formed on April 28, 1971.
•Jurisdiction under Federal government of the
United States

8. •OSHA headquarters is in Washington, D.C.
•It help employers reduce injuries ,illness and
death in the work place.
•A major component of the Hazard
Communication program by OSHA is Material
Safety Data Sheets (MSDS).

9. MSDS

10. What is an MSDS Sheet?
•Material safety data sheets are documents that contains
information that may required in hazardous area.
•An MSDS sheet contains various properties of the substance
, including physicals data and safety information.
•it is intended to provide workers and emergency personnel with
procedures for handling or working with that substance in a safe
manner.
•Explain the physical and chemicals characteristics.
•widely used system for cataloging information on hazardous
ingredients.

11. •Physical hazards, such as fire, explosion and reactivity.
•One reason for the widespread popularity of the MSDS is
that it is an easy to understand document.
•Health hazards such as First-aid and emergency
information.
•may include instructions for the safe use and
potential hazards associated with a particular material or
product.
•These data sheets can be found anywhere where
chemicals are being used.

12. Why are MSDS sheets useful ?
 Mainly are in occupational setting only MSDS sheets
provide valuable data for safe use and potential
hazardous that could come about from using the given
chemical.
 Because different companies provide different
chemicals , different MSDS sheets can be mode up
different variations of the same substance .

13. What data do MSDS sheets
contain?
 All countries and supplies have different form of MSDS
sheets , so we will concentrate on the united states
version .
 The form itself contains data on boiling point
, melting point, specific gravity , solubility appearance
and odor , reactivity , flammability and how to handle
these .

14. Where to find MSDS
 If anyone ever needs to see a copy of the MSDS in order to
look up information on a chemical, there are numerous
ways to obtain the material safety data sheets.
 The first assistant or manager of any store or warehouse
should be your first target when looking for the material
safety data sheets.

15. An example MSDS in
a US format provides
guidance for
handling a
hazardous substance
and information on
its composition and
properties.

17. Symbols of hazards
Corrosive
A substance that may destroy living tissue on
contact.
It causes a burn.
Flammable
A substance that can catch fire easily.

18. Oxidising
Explosive
This type of substance gives of a large
A substance that may explode if
amount of heat when in contact with
it comes into contact with a
other substances.
flame or heat. It may also
explode due to friction or shock.
Radiation
Harmful These substances are radioactive.
A substance that may cause Radiation can damage cells and
harm in some way cause cancer.

19. Irritant Biohazard
A substance that may cause irritation These are living organisms that
to the skin, eyes or inside your body. may cause infection.
Toxic
Environmental Hazard
A substance that is poisonous if
These substances damage
swallowed or breathed in. It may
or pollute the environment.
even go through your skin.

20. Hazard Communication Standard
Chemical manufacturers must
 Determine a chemical’s hazards
 Provide label.
Employers must
 Provide a hazard communication program
 Maintain MSDSs
 Training hazardous material
Employees must
 Read labels and MSDSs
 follow employer instruction and warnings
 Identify hazards before starting a job
 Participate in training

21. Routes of Entry
 Skin and eye contact
 Inhalation
 Swallowing
 Penetration (skin absorption)

22. Personal Protective Equipment (PPE)
 Dust mask and respirators
 Glasses, goggles, and face shields
 Hearing protection Gloves
 Foot protection
 Head protection
 Apronsorfull-bodysuits

23. Hazardous Materials First Aid
 Eyes - Flush with water
for 15 minutes
 skin - Wash with soap
and water
 Inhalation - Move to
fresh air
 Swallowing - Get
emergency medical
assistance

24. Important of label
 the identity of the chemical
 Name , address , emergency phone number of
manufacturer
 Special handling instructions
 basic PPE recommendations
 First aid, fire response, spill cleanup .

26. Spills and leaks
Evacuate the area
Notify a supervisor or the
 emergency response
team
 Remove ignition sources
(if safe to do so)
Stay away

27. NFPA Labeling Systems
 NFPA = National Fire Protection
Association
 Blue = Health
 Red = Flammability
 Yellow = Reactivity
 White = Other hazards or special handling
 Scale: 0 (NoHazard) to 4 (ExtremeHazard)

28. NFPA 704 SYSTEM
4-Severe
3-Serious
2-Dangerous
1 -Minor
0-None/Negligible

29. Conclusion
 Hazcom program help and provide the employers and
employees work in a safe environment.
 With Hazcom too ‘Right To Know’
laws are practiced among workers during
handling hazardous substances.
