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 9/16/2017

Purpose 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 More than 30 million workers are potentially exposed to one or more chemical hazards. There are an estimated 650,000 existing hazardous chemical products, and hundreds of new ones are being introduced annually. This poses a serious problem for exposed workers and their employers.

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. More than 30 million workers are potentially exposed to one or more chemical hazards. There are an estimated 650,000 existing hazardous chemical products, and hundreds of new ones are being introduced annually. This poses a serious problem for exposed workers and their employers.

HazCom Requirements The hazardous chemical inventory Material Safety Data Sheets (MSDSs) Labels, tags or signs The written Hazard Communication program Industrial Safety Lecture Three 9/16/2017

Background 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 the HCS will result in a reduction of illnesses and injuries caused by chemicals. Employers will have the information they need to design an appropriate protective program.

Background 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 Employees will be better able to participate in these programs effectively when they understand the hazards involved, and to take steps to protect themselves. Together, these employer and employee actions will prevent the occurrence of adverse effects caused by the use of chemicals in the workplace. MSDS

Employers 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 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 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 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 pesticides are covered under the Federal Insecticide Fungicide and Rodenticide Act Federal Food, Drug and Cosmetic Act Bureau ATF (booze) Consumer Products Safety Act

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 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 Can be compiled for the entire facility or individual departments

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 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 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 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 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

affix new labels to comply with the standard if The employer need not affix new labels to comply with the standard if existing labels already covey the required 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 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 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 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 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 Such as monitoring done by the employer continuous monitoring devices visual appearance or odor Specific procedures, work practices, emergency procedures and PPE Explain labeling system, MSDS, how employees can obtain and use haz info.

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 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 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. 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 All workplaces where employees are exposed to hazardous chemicals must have a written plan The plan does not have to be lengthy or complicated Many trade associations and other professional groups have provided sample programs and other assistance materials to affected employers

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)

Documentation 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 Hazard Communication
