OSHA’s Revised Hazard Communication Standard

Purpose of OSHA’s Hazard Communication Standard To ensure that employers and employees know about chemical hazards and how to protect themselves so that the incidence of illnesses and injuries due to hazardous chemicals is reduced. Hazard Communication Program Container Labeling Safety Data Sheet SDS Program Label

Revisions to the Hazcom Standard • OSHA revised its Hazard Communication Standard to align with the United Nations’ Globally Harmonized System of Classification and Labeling of Chemicals (GHS). • The changes to the Hazard Communication standard will help ensure improved quality and consistency in the classification and labeling of chemicals and it will also enhance your comprehension of the hazards of the materials with which you work.

There are Two Changes to the Hazcom Standard 1) new labeling elements and 2) a standardized format for Safety Data Sheets (SDS), formerly known as Material Safety Data Sheets (MSDS).

The New Labeling Elements Each container of hazardous chemicals entering the workplace must be labeled or marked with: • • • Product identifier Signal word Hazard statement(s) Pictogram(s) Precautionary statement(s) Name, address and telephone number of the manufacturer, importer, or other responsible party

Label Elements • Product identifier § Chemical name, code number, or batch number The product identifier can be used to find the corresponding SDS • Signal word § “Danger” or “Warning” • Pictogram(s) § Black hazard symbol with red frame.

Label Elements, cont. • Hazard statement(s) § Describe the nature of the hazard(s) of the chemical, including where appropriate, the degree of hazard. • Precautionary statement(s) § A phrase that describes recommended measures that should be taken to minimize or prevent adverse effects resulting from exposure. • Name, address and telephone number of the chemical manufacturer, distributor, or importer

Pictograms Health Hazard Carcinogen Reproductive Toxicity Respiratory Sensitizer Target Organ Toxicity Aspiration Toxicity Mutagenicity Skull and Crossbones Acute Toxicity (fatal or toxic) Exclamation Mark Irritant (skin & eye) Skin Sensitizer Acute Toxicity (harmful) Narcotic Effects Respiratory Tract Irritant

Pictograms Gas Cylinder Gases Under Pressure Corrosion Skin Corrosion/Burns Eye Damage Corrosive to Metals Exploding Bomb Explosives Self-Reactives Organic Peroxides

Pictograms Flame Over Circle Oxidizers Flame Flammables Pyrophorics Self-Heating Emits Flammable Gas Self-Reactives Organic Peroxides

Secondary Labels ! Copy of manufacturer’s label or ! Product identifier and words, pictures, symbols, or combination thereof, which provide at least general information regarding the hazards of the chemicals, and which, in conjunction with the other information immediately available to employees under the hazard communication program, will provide employees with the specific information regarding the physical and health hazards of the hazardous chemical

Safety Data Sheets (SDS) • Prepared by the chemical manufacturer or importer and describe: § Physical hazards, such as fire and explosion § Health hazards, such as signs of exposure § Routes of exposure § Precautions for safe handling and use § Emergency and first-aid procedures § Control measures § Must be readily accessible to employees in their work area

The Standardized SDS Format 16 Sections 1. 2. 3. 4. 5. 6. 7. 8. Identification Hazard(s) identification Composition/information on ingredients First-aid measures Fire-fighting measures Accidental release measures Handling and storage Exposure control/personal protection

Safety Data Sheets (SDS) • Format: 16 Sections (cont. ) 9. Physical and chemical properties 10. Stability and reactivity 11. Toxicological information 12. Ecological information 13. Disposal information 14. Transport information 15. Regulatory information 16. Other information

Safety Data Sheet (SDS) sample • SDS are useful for: § Learning potential hazards § Determining safe handling procedures § Emergency response • Example: send a copy along with an employee going to the Doctor after an incident. )

Exercise: Review a Label and the Corresponding SDS from the Workplace and Discuss: • The product identifier that is on both the label and the SDS • The potential hazards of the product • The recommended protective measures such as engineering controls, work practices, and the use of PPE • The sections of the SDS that address these and other issues (first aid etc)

Summary • OSHA’s Hazard Communication Standard is based on a simple concept: You have a need and a “right-to-know” about the hazards and identities of the chemicals you are exposed to when at work. • You also need to know what protective measures are available to prevent adverse effects.
