Bi-Weekly Safety Meeting October 1, 2015 HAZARD COMMUNICATION Your Right To Know Bi-Weekly Safety Meeting October 1, 2015

OSHA Standard The Hazard Communication Standard (HCS) is an OSHA regulation intended to prevent adverse health effects of hazardous materials in the workplace. It requires chemical manufacturers, suppliers, and importers to assess the hazards of the chemicals they produce or import, and to inform employers, customers, and workers of these hazards.  In 2003, the United Nations (UN) adopted the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). The GHS includes criteria for the classification of health, physical and environmental hazards, as well as specifying what information should be included on labels of hazardous chemicals as well as safety data sheets. In 2012 OSHA announced that the HCS had been revised to align with the GHS.

OSHA Standard HCS specifies that information on chemical hazards be provided through the following: access to safety data sheets (SDS) properly labeled chemical containers appropriate training on chemical hazards and safe work procedures

Safety Data Sheets Safety Data Sheets (SDS) are the backbone of the Hazardous Communication System. They provide comprehensive and specific information used not only by workplaces that manufacture, use, transport or store hazardous chemicals, but also by emergency responders, poison control centers, and transporters of dangerous goods.

Safety Data Sheets The information contained in the SDS is presented in a consistent user-friendly, 16-section format: Sections 1 through 8 contain general information about the chemical, identification, hazards, composition, safe handling practices, and emergency control measures (e.g., fire fighting). Sections 9 through 11, and 16 contain other technical and scientific information, such as physical and chemical properties, stability and reactivity information, toxicological information, and exposure control information Sections 12 through 15 to be consistent with the UN GHS system, but OSHA will not enforce the content of these sections because they concern matters handled by other agencies.

Pictograms Nine hazard pictograms that correspond with the health and physical hazards, and are intended to help workers determine chemical hazards at a glance.

Sample SDS

Hazard Classification Chemicals are classified according to two types of hazards: HEALTH toxic effects on the body causing damage to skin, eyes, or lungs through corrosion encouraging the development of cancer or other serious health conditions PHYSICAL fire, explosion, or other violent reaction

Health Hazards Acute Toxicity Skin Corrosion/Irritation Serious Eye Damage/Eye Irritation Respiratory or Skin Sensitization Germ Cell Mutagenicity Carcinogenicity Reproductive Toxicity Target Organ Systemic Toxicity – Single and Repeated Dose Aspiration Toxicity

Health Effects can be Local or Systemic Health Hazards Health Effects can be Local or Systemic Local The site on the body at which a toxic material makes contact with a harmful effect. Systemic Occurs when a toxic material is absorbed into the body and carried into the blood stream to produce a harmful effect on organs and body systems.

Health Effects can be Acute or Chronic Health Hazards Health Effects can be Acute or Chronic Acute Effects that are severe and sudden in onset. They appear immediately after an exposure of short duration. Chronic Effects that develop slowly and do not appear for months or years after long-term exposure.

Health Hazards Routes of Entry Lungs (inhalation) Skin (absorption) Mouth (ingestion) Eyes

Physical Hazards Explosives Flammability – gases, aerosols, liquids, solids Oxidizers – liquid, solid, gases Self-Reactive Pyrophoric – liquids, solids Self-Heating Organic Peroxides Corrosive to Metal Gases Under Pressure Water-Activated Flammable Gases

Labels Labels are attached to containers to provide workers with “at a glance” information about chemical hazards.  They are limited in the amount of information they present and are designed to provide a brief summary of the more detailed information available on the SDS.

Labels Should Contain: Product Identifier – Should match the product identifier on the Safety Data Sheet Signal Word – Either use “Danger” (severe) or “Warning” (less severe) Hazard Statement – A phrase assigned to a hazard class that describes the nature of the product’s hazards Precautionary Statements – Describes recommended measures to minimize or prevent adverse effects resulting from exposure Supplier Identification – Name, address, and telephone number of the manufacturer or supplier. Pictograms – Graphical symbols intended to convey specific hazard information visually

TOXICOLOGY concerned with the study of the adverse effects of chemicals on living organisms

Information & Definitions on Determining Exposure Permissible Exposure Limit (PEL) The PEL is the maximum concentration of an airborne contaminant to which an unprotected worker may be exposed during the course of workplace activities. PEL Ceiling Value The concentration of a substance that should not be exceeded at any time. Concentration – Parts Per Million (PPM) The concentration of a substance is a measure of the "strength" of that substance and can be measured different ways: % = Parts per hundred PPM = Parts per million    PPB = Parts per billion

Information & Definitions on Determining Exposure Time Weighted Average (TWA) PELs are based on a time weighted average (TWA) exposure. A TWA is the average exposure over a specified period of time, usually a nominal eight hours. This means that, for limited periods, a worker may be exposed to concentrations higher than the PEL, so long as the average concentration over eight hours remains lower.

Your Right To Know… Our clients provide SDSs for the contractors and employees who work on their sites. It is every employee’s responsibility to know the location of the SDSs for the sites they work at. Site orientation, the project JSA, and personal SMART cards are tools to help us to remember to remain up to date on the location of this vital information.
