3 Learning ObjectiveTLO: Comply with OSHA’s new Hazard Communication Standard (HCS) and function within the Globally Harmonized System of Classification & Labeling of Chemicals.The Terminal Learning Objective for this course is to gain knowledge on how to successfully implement a Hazard Communication Program which complies with the OSHA HCS 2012 and Globally Harmonized System of Classification & labeling of Chemicals.The purpose of this section is to ensure that the hazards of all chemicals produced or imported are classified, and that information concerning the classified hazards is transmitted to employers and employees. The requirements of this section are intended to be consistent with the provisions of the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS), Revision 3. The transmittal of information is to be accomplished by means of comprehensive hazard communication programs, which are to include container labeling and other forms of warning, safety data sheets and employee training.Construction Safety Council (800)
4 Learning ObjectiveEO: Identify the purpose, scope, benefits, elements and effective dates of GHS. EO: Compare and contrast GHS with HCS. EO: Define the 16 physical and 10 health hazard classifications. EO: Describe the requirements of a 16-section SDS. EO: List the new label requirements. EO: Identify controls to eliminate and/or reduce exposure to hazards.The changes that will affect the employer (contractor) would be to train employees on the new hazard classifications (pictograms), make employees aware of new labels on containers and the new Safety Data Sheet (SDS) format. There are no substantive changes to the written hazard communication program requirements, only some terminology has changed (e.g., Material Safety Data Sheets). These changes, however, will require employers to review their current Hazard Communication Program and identify old Material Safety Data Sheets (MSDSs) and replace them with the current SDS format sheets.Construction Safety Council (800)
5 Effective DatesDec. 1, 2013 – Train employees on the new label elements and SDS format.Dec. 1, 2015 – Shipment of products with old system ends.June 1, 2016 – Full implementation.

8 National Fire Protection Association (NFPA 704M) BlueRedWhiteYellow41National Fire Protection Association (NFPA 704)The NFPA 704 Diamond is a means of disseminating hazard information for a material. The diamond is divided into four sections. Each of the first three colored sections (blue, red & yellow) has a number in it associated with a particular hazard. The higher the number is, the more hazardous a material is for that characteristic. The fourth section (white) includes special hazard information.The NFPA 704 standard provides a readily recognized, easily understood system for identifying specific hazards. It addresses the health, flammability, instability, and related hazards that may be presented as short-term, acute exposures that are most likely to occur as a result of fire, spill, or similar emergency.The objectives of NFPA 704 are:To provide an appropriate signal or alert for the protection of both public and private emergency response personnel.To assist in planning for effective fire and emergency control operations, including clean-up.To assist all designated personnel, engineers, job-site, and safety personnel in evaluating hazards.Construction Safety Council (800)

14 New Definitions (HCS 2012) Classification Hazard category Hazard class Hazard not otherwise classified “Unclassified Hazard”Hazard statementLabel elementsPictogramThe HCS 1994 is a performance-oriented standard that provides guidance for defining hazards and for performing hazard determinations. However, the current standard does not specify an approach or format to follow. The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) has certain aspects that are performance-oriented, but the key provisions are a uniformity-oriented approach for the classification and presentation, through labeling and safety data sheets, of hazard information.The HCS 2012 is written as a modification to the existing standard, and those parts of the standard that do not relate to the GHS, or are already consistent with it remain unchanged. Additionally, some minor changes to terminology have been made in order to align this rule with language used in the GHS. For example, the term "hazard determination" has been changed to "hazard classification" and "material safety data sheet" has been changed to "safety data sheet."Construction Safety Council (800)

29 Recognition of Hazards What do you see?Visible material in the airSettled dustWarning signs, labels & decalsConcrete cutting with saw creates obvious dust exposure.Visible material in the air – If you see visible clouds of vapor or particles, there may be a serious exposure problem. Remember, however, that most gases and vapors are invisible, and that often the most dangerous particles are too small to see.Settled dust – if there is chemical dust on the ground or other surfaces, it probably got there by settling out of the air. If disturbed, settled dust can become airborne again.Warning signs, labels & decals – as required by OSHA’s Hazard Communication Standard (29 CFR ) and other applicable standards.Group Discussion…What health hazards do you see on your job?Construction Safety Council (800)
30 Anticipation of Health Hazards knowing the history of the work involved.Worker experience and education.To anticipate hazards:Survey job-site conditionsBe aware of the actions and behaviors of workers.Health hazards can be anticipated by knowing the history of the work involved as well as through worker experience and education; learn all the hazards associated with your job and be better prepared to make good decisions regarding your health and safety.Generally, hazards associated with a particular job are either inherent (present before the worker shows up); or hazards can be created by the work (e.g., welding & cutting, use of fuel powered equipment, etc.).To anticipate hazards:Survey job-site conditionsBe aware of the actions and behaviors of workers.What hazards can you anticipate in this picture?Old fuel storage tank be excavated – site being prepared for rebuild (fueling station).Construction Safety Council (800)
33 Responsibility to Self & Family A worker’s exposure to hazardous materials on the job can be unknowingly brought back to a person’s home; heavy metals such as lead dust, concrete crusted clothing and variety of oils, greases and solvents can all be unintentionally poisoning your family!As a worker who might be exposed to these hazards, you have a responsibility to wear personal protective equipment (PPE), practice good hygiene and take advantage of training programs like this. Learn of the hazards associated with your job and protect your family.Occupational health hazards can unexpectedly be brought home; wear personal protective equipment (PPE) on the job and do not bring home health hazards that can harm your family!Construction Safety Council (800)

46 Single Word DANGER WARNING CAUTION NOTICE HCS 2012 DANGER WARNING A signal word is a word that typically appears near the top of a warning, sometimes in all capital letters. Common examples include DANGER, WARNING, CAUTION, and NOTICE. The signal word is generally understood to serve a dual purpose: alerting the user to a hazard and indicating a particular level of hazard. The new HCS requires the use of one of two signal words for labels – DANGER or WARNING – depending on the hazard classification of the substance in question. DANGER is used for the more severe hazard categories, while WARNING denotes a less serious hazard.Construction Safety Council (800)
47 Labels & Other Forms of Warning Product identifierSignal word (Danger or Warning)(f)(1)(iii) Hazard statement(s);(f)(1)(iv) Pictogram(s);(f)(1)(v) Precautionary statement(s); and,(f)(1)(vi) Name, address, and telephone number of the chemical manufacturer, importer, or other responsible party.
49 Labels & Other Forms of Warning OSHA is maintaining the current approach to allowing alternatives to labels on each stationary process container; and the exception for portable containers under the control of the person who filled them with the chemical.Labels on incoming containers are not to be removed or defaced unless immediately replaced by another label.Workplace labels are to be prominently displayed and in English, other languages are permitted.
50 Contractors Guide to HCS Compliance Become familiar with the OSHA’s Hazard Communication Standard (29 CFR )Prepare and implement a Hazard Communication Program.Assign a competent person to implement all aspects of the Program.Identify all hazardous chemicals in the workplace.Labels and other forms of warning must be in place.Safety Data Sheets (SDSs) available.Employee information and training conducted.Remember…The best protection is prevention.
