5. OHSA’s Haz-Com Standard
12/3/2016
OSHA’s Hazard Communication Standard is designed to protect
employees from hazardous chemicals used or stored in the work
setting.
Also referred to as the "Right-To-Know Law" Law, the Hazard
Communication Standard requires that information and
training (i.e.,hazcom training) be provided to any employees
who have the potential of being exposed to a hazardous chemical
“under normal condition of use or in a foreseeable emergency.”
Such hazcom training requires the presence of hazardous
chemicals be communicated to employees in a variety of ways,
including:

6. Purpose
 The purpose of the standard is to
make sure that the hazards of
chemicals are evaluated
 That information concerning their
hazards is communicated to
employers and employees
12/3/2016

7. Who is covered
OSHA’s Hazard Communication
(HazCom) standard applies to general
industry, shipyard, marine terminals,
longshoring, and construction employment
and covers chemical manufacturers,
importers, employers, and employees
exposed to chemical hazards.

18. Background
 The Hazard Communication Standard (HCS) is based on a
simple concept--that employees have both a need and a
right to know the hazards and identities of the chemicals
they are exposed to when working
12/3/2016

19. Background
 They also need to know what protective measures are
available to prevent adverse effects from occurring
 The HCS is designed to provide employees with the
information they need
MSDS
12/3/2016

20. Employers
 Employers are required to provide information to their
employees about the hazardous chemicals to which they
are exposed using:
 A hazard communication program

 information and training
12/3/2016

21. Warehouse and Retail Operations
 In work operations where employees only handle
chemicals in sealed containers, which are not opened
under normal conditions
 Employers must only do the following:
 Ensure labels on incoming chemicals are not
defaced or removed
 Maintain copies of any material safety data sheets that are
received with incoming shipments
 Obtain MSDS a.s.a.p. for shipments received w/out MSDS
12/3/2016

22. Warehouse and Retail Operations
 Provide employees with information and training (no written
program required) to the extent necessary to protect them
in the event of a spill or leak of a hazardous chemical from
a sealed container
12/3/2016

23. Labeling Exemptions
 Other federal agencies control the labeling requirements
for the following substances:

program may be kept at the main location
12/3/2016

29. Labels, Tags and Markings
 The employer must ensure that each container of
hazardous chemicals in the workplace is labeled, tagged
or marked with the following:
 Identity of the hazardous chemical
 Appropriate hazard warnings
 This above labeling information is required of the
manufacturer so the employer must ensure that the
original labels from the manufacturer are on all
containers and remain legible
12/3/2016

into which hazardous chemicals are transferred from
labeled containers, and which are intended only for the
immediate use by the employee who performs the
transfer
12/3/2016

33. The employer need not affix new labels to
comply with the standard if existing labels
already covey the required information
12/3/2016

34. New Hazard Information
 Manufacturers, importers, distributors
and employers who become newly
aware of significant information
regarding chemical hazards shall:

telephone of the
manufacturer
12/3/2016

55. CHEMICAL MANAGEMENT
 Emergency Management
 Prepare for and prevent emergencies
 Fires
 Spills/releases
 Injuries
 Emergency response must be part of basic work
procedures and employees must be trained.
 Evacuation
 Fire brigade
 Spill response
 Medical response

56. CHEMICAL MANAGEMENT
 Incident Investigations
 All incidents, regardless of severity, must be investigated
– and lessons learned used for prevention
 Formal investigation of serious incidents
 Accountability at all levels
 Management of Plant at which incident occurred through
employees and investigation team.

57. CHEMICAL MANAGEMENT
 Proper and Safe Chemical Management
 Part of the facility culture
 Part of every employee’s activity
 Recognition of safety improvement
 Safety is everyone’s responsibility.

58. Setting up a program
 The HCS covers both:
 Physical hazards (such as flammability), and
 Health hazards (such as irritation, lung damage, and cancer)
 Most chemicals used in the workplace have some hazard
potential, and thus will be covered by the rule
12/3/2016

59. Setting up a program
 One difference between this rule and many others adopted
by OSHA is that this one is performance-oriented
 That means that you have the flexibility to adapt the rule to
the needs of your workplace, rather than having to follow
specific, rigid requirements
12/3/2016

60. Setting up a program
 Make a list of all chemicals in the workplace that are
potentially hazardous
 The best way to prepare a comprehensive list is to
survey the workplace
 Identify chemicals in containers, including pipes
 Establish purchasing procedures so that MSDSs are
being received before a material is used in the
workplace
12/3/2016

61. Identify hazardous chemicals
 Compile a complete list of the potentially hazardous
chemicals in the workplace
 Determine if you have received material safety data
sheets for all of them
 If any are missing, contact your supplier and
request one
 You should not allow employees to use any
chemicals for which you have not received an
MSDS
12/3/2016

62. Preparing and implementing a hazard
communication program
 All workplaces where employees are
exposed to hazardous chemicals must have
a written plan
 The plan does not have to be lengthy or
complicated
12/3/2016

63. Employee training
 If there are only a few chemicals in the workplace, then you
may want to discuss each one individually
 Where there are large numbers of chemicals, or the
chemicals change frequently, you will probably want to
train generally based on the hazard categories (e.g.,
flammable liquids, corrosive materials, carcinogens)
12/3/2016

64. Documentation
 The rule does not require
employers to maintain records of
employee training, but many
employers choose to do so
 This may help you monitor your
own program to ensure that all
employees are appropriately
trained
Hazard
