ohsa s haz com standard
OHSA’s Haz-Com Standard

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:

Industrial Safety Lecture Three

  • 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
who is covered
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.


hazcom requirements
HazCom Requirements
  • The hazardous chemical inventory
  • Material Safety Data Sheets (MSDSs)
  • Labels, tags or signs
  • The written Hazard Communication program

Industrial Safety Lecture Three

  • 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
  • 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


  • Employers are required to provide information to their employees about the hazardous chemicals to which they are exposed using:
    • A hazard communication program
    • labels and other forms of warnings
    • material safety data sheets (MSDS)
    • information and training
warehouse and retail operations
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
warehouse and retail operations1
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
labeling exemptions
Labeling Exemptions
  • Other federal agencies control the labeling requirements for the following substances:
    • Pesticides
    • Chemicals covered under the Toxic Substance Control Act
    • Foods or food additives
    • Distilled Spirits, tobacco
    • Consumer products, lumber, cosmetics
    • Hazardous wastes
employer requirements written program
Employer Requirements-Written Program
  • Employers must develop a written program that covers at least:
    • Labels and other forms of warnings
    • Material Safety Data Sheets
    • Employee Information and Training
employer requirements written program1
Employer Requirements-Written Program
  • Employers must develop a written program that covers at least:
    • A list of the hazardous chemicals known to be present at the facility along with MSDS’s for each chemical
    • The methods the employer will use to inform employees of the hazards non-routine tasks
    • The hazards of chemicals in unlabeled pipes
multi employer workplaces
Multi-Employer Workplaces
  • If employees of other employers could be exposed to hazardous chemicals the program must include:
    • Methods to provide contractor employees with on-site access to MSDS for each chemical those workers may be exposed to
    • The methods used to inform other employers of any precautionary measures to be taken for normal and emergency situations
    • The employers chemical labeling system
consumer products exemption
Consumer Products Exemption
  • Any consumer product as defined in the Consumer Product Safety Act where the employer can show that:
    • It is used in the workplace for the purpose intended
    • The use results in a duration and frequency of exposure which is not greater than the range of exposures that could reasonably be experienced by consumers when used for the purpose intended
written program availability
Written Program Availability
  • The employer must make the written program available, upon request, to:
    • Employees and their designated representatives
  • Where work is carried out at more than one location, the program may be kept at the main location
labels tags and markings
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
container labeling exemption for portable containers
Container Labeling Exemption for Portable Containers
  • The employer is not required to label portable containers 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

The employer need not

affix new labels to comply

with the standard if

existing labels already covey

the required information

new hazard information
New Hazard Information
  • Manufacturers, importers, distributors and employers who become newly aware of significant information regarding chemical hazards shall:
    • Revise the labels for the chemical within three months
    • Revise the MSDS for the chemical within three months
msds kept in other forms
MSDS kept in other forms
  • MSDS may be kept in any form including operating procedures
  • It may be more appropriate to address the hazards of a process rather than individual hazardous chemicals
employee information and training
Employee Information and Training
  • Employers must provide employees information and training on hazardous chemicals in their work area:
    • At the time of their initial assignment
    • Whenever a new physical or health hazard the employees have not previously been trained about is introduced into their work area
  • Training may cover categories of hazards
employee information
Employee Information
  • Employers must inform employees:
    • Of the training requirements of this section (1910.1200 (h) Employee information and training.);
    • Any operations in their work area where hazardous chemicals are present;
    • The location and availability of the written hazard communication program
employee training
Employee Training
  • Employee training shall include at least:
    • The means to detect the presence or release of a hazardous chemical in the work area
    • The physical and health hazards of chemicals in the work area
    • Measures employees can take to protect themselves
    • Details of the employers specific program

setting up a program
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
setting up a program1
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
setting up a program2
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
identify hazardous chemicals in the workplace
Identify hazardous chemicals in the workplace.
  • 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
preparing and implementing a hazard communication program
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
employee training1
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)
  • 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
