Hazard Communication



subpart z toxic hazardous substances 1910 1000 1450 fy2006
Subpart Z - Toxic & Hazardous Substances (1910.1000 - 1450)FY2006

Hazard Communication - Written program

Hazard Communication - Information & training

Hazard Communication - Training initially & for new hazards

Standard: 1910.

Hazard Communication - Material Safety Data Sheets

Hazard Communication - Label identification

  • Hazard Communication Program
  • Labels and other forms of warnings
  • Material Safety Data Sheets (MSDS)
  • Information and training
  • Health Hazards
  • 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.


  • 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


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 program10
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
labels nfpa diamond
Labels – NFPA Diamond
  • RED - Flammability
  • BLUE - Health
  • YELLOW - Reactivity

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



chemical exposure severity duration
Chemical ExposureSeverity & Duration
  • “Acute” effects usually occur rapidly as a result of short-term exposures, and are of short duration
  • “Chronic” effects generally occur as a result of long-term exposure, and are of long duration
  • Visible destruction, or irreversible damage to body tissue
  • Acids
  • Caustics (or bases)


(or bases)

pH Scale






Routes of Exposure

Inhalation - Absorbtion - Ingestion - Injection -

  • Inhalation - most common
  • Skin absorption
  • Ingestion
  • Injection

Health Hazards

Toxicity vs. hazard - toxicity is used to describe the ability of the substance to cause a harmful effect. Everything is toxic at some dose.


Health Hazards

Toxicity vs. Dose - There is a balance between toxicity and dose. Dose is the amount of something the individual is exposed to or comes in contact with. The lower the toxicity, the greater the dose that can be tolerated without ill effects. The greater the toxicity, the lower the dose that can be tolerated without ill effects.


Chemical Exposure Limits

  • Time Weighted Average (TWA) based on an 8 hour day.
  • Ceiling Limits based on maximum exposure.
  • Exposure Limits are established for all chemicals.
Major Types

Corrosives - cause tissue damage and burns on contact with skin or eyes

Primary Irritants - cause intense redness or swelling of skin or eyes on contact. No permanent tissue damage

Sensitizers- cause an allergic skin or lung reaction

Acutely Toxic Materials - cause an adverse effect even at very low doses

Carcinogens - may cause cancer

Teratogens - may cause birth defects

Organ Specific hazards - damage to specific organ systems such as liver or lungs

Health Hazards


Health Hazards

  • Training and communication - knowing how to work safely with chemicals that pose a hazard - i.e. bulletins, MSDS, etc.. THE RIGHT TO KNOW
  • Environmental monitoring - Industrial Hygiene air sampling
  • Personal monitoring - check yourself and co-workers for symptoms - i.e. skin rashes, eye or throat irritation, strong odors
chemicals used during sanitation
Chemicals Used During Sanitation
  • Detergents
  • Disinfectants
  • Sterilants
general characteristics of detergents
General Characteristics of Detergents

ALCOHOLS (Isopropyl or Ethyl Alcohol)

Wide germicidal activity, non corrosive, but poses a fire hazard.

Limited residual activity due to evaporation.

Alcohols provide limited activity in the presence of organic matter.

Not considered effective against bacterial or fungal spores.

Excellent for disinfecting instruments or other small objects.

Too expensive for general use in the hatchery.

Must use as a 70-95% concentration for effectiveness.

HALOGENS (Iodines or hypochlorites)

Provide wide germicidal activity but are corrosive.

Limited activity when in the presence of organic matter.

Poor residual activity, low toxicity, but may stain surfaces.

Not effective as sporocidal agents.

Effective at low concentrations for disinfecting clean, small objects.

Low cost but requires frequent applications.
