Introduction
The history of the Federal Occupational Safety and Health Act's Hazard Communication Standard (HCS) began in 1975. At that time, OSHA initiated programs calling for chemical manufacturers to label containers of hazardous chemicals. By 1977, OSHA had filed in the Federal Register for the standardization of hazardous chemical labeling. OSHA proposed the HCS again in March 1982, when it outlined five goals that together serve as the cornerstone for the current HCS.
The HCS was promulgated to ensure that all employers receive the information they need to inform and train their employees properly on the hazardous substances they work with and to help design and put in place employee protection programs. It also provides necessary hazard information to employees so they can participate in and support protective measures in place at their workplaces.
On April 7, 1986, a three‑bill, Michigan Right to Know package was signed into law. The package, which is essentially an enhanced version of the Federal Right to Know program, requires all employees that work with hazardous chemicals to conform with the law regardless of their employer's status as manufacturer or non-manufacturer. The Right to Know Law was performance oriented.
1) Michigan's Right to Know Law ‑ provided access to chemical information to workers whose jobs involve the routine use of hazardous chemicals. The requirements characteristic of the federal standard (29 C.F.R. 1910.1200) were adopted by the Michigan Right to Know Law - Part 42, 92 and 430. Hazard Communication.
2) Michigan's Firefighter Right to Know Law ‑ provides the fire chief of the organized fire department for the jurisdiction in which the person is located the right to request and receive a list of chemicals and SDSs used at a specified location. Under the law, if the fire chief requests it, the following information must be provided within 10 working days of the query:
a) a listing of all hazardous chemicals at the location,
b) SDSs for all hazardous chemicals at the location, and
c) information pertaining to the quantity and location of the chemicals.
In addition, an employer must provide the fire chief with a written update when there is a significant change relating to fire hazards and the quantity, location, or presence of hazardous chemicals in the workplace.
3) Michigan's Community Right to Know Law ‑ made it possible for any resident of an employer's county to request a listing of and SDSs for all hazardous chemicals present at that employer's workplace. We say made because the 1986 Superfund Amendment and Reauthorization Act (SARA) replaced the Community Right to Know Law, enforced by EPA. Under Title III of SARA, an employer is required to provide an even more comprehensive statement regarding hazardous chemicals in the workplace to members of the community.
MIOSHA adopted OSHA’s HCS by reference on February 5, 2014. The Michigan Safety and Health Act (P.A. 154 of 1974 as amended), Section 14 was amended on December 27, 2013 to reflect changes in SDS.
Scope
The Right to Know Law applies to all Michigan employers. This section requires chemical manufacturers or importers to classify the hazards of chemicals which they produce or import, and all employers to provide information to their employees about the hazardous chemicals to which they are exposed, by means of a Hazard Communications Program, labels and other forms of warning, SDSs, and information and training. In addition, this section requires distributors to transmit the required information to employers. (Employers who do not produce or import chemicals need only focus on those parts of this rule that deal with establishing a workplace program and communicating information to their workers.)
All workers, who may be exposed to hazardous chemicals during the course of routine work or in a foreseeable emergency, are included under the Right to Know Law. Employees working in laboratories are covered under the Part 431 Hazardous Work in Laboratories Standard (Chemical Hygiene Plan).
Chemical Inventory
The written Hazard Communication Program must include a hazardous chemical or product inventory for substances used or stored at the facility. A “hazardous chemical” means any chemical which is classified as a physical hazard or a health hazard, a simple asphyxiant, combustible dust, pyrophoric gas, or hazard not otherwise classified. Typical examples include gasoline, diesel fuel, motor oil, lubricants, hydraulic fluid, wood preservatives, wood finishes, solvents, and parts cleaners. A chemical inventory is the basis for completing the rest of the requirements of Michigan’s Right to Know Law.
See Appendix A for an example of a Chemical Inventory List that can be used to create your own chemical inventory.
Classification of Hazardous Chemicals
Chemical manufacturers and importers shall evaluate chemicals produced in their workplaces or imported by them to classify the chemicals in accordance with the Standard.
The chemical classification process involves identifying and considering the full range of available scientific literature and other evidence concerning the potential hazards. There is no requirement to test the chemical to determine how to classify its hazards. Appendix A to §1910.1200 shall be consulted for classification of health hazards, and Appendix B to §1910.1200 shall be consulted for the classification of physical hazards.
An employer may produce its own hazardous materials as products for sale or as by-products of research. In this case, the employer is responsible for developing SDSs and container labels for these materials.
Written Hazard Communication Program
Employers must develop, implement and maintain at the workplace a written, comprehensive Hazard Communication Program that includes container labeling, employee access to SDSs and an employee training program. The plan must also contain an inventory of the hazardous chemicals and details regarding how the employer will inform employees of the hazards associated with these substances. The employer, upon written request, must provide the written plan to employees, their designated representatives and MIOSHA representatives.
When outside contractors work at a facility, the resident company must ensure their safety from hazardous chemicals or products and include the following in the written Right to Know Program:
· How the facility will provide the outside contractor with copies of appropriate SDSs.
· How the company will inform the contractor of any precautionary measures they should take to protect employees during normal operations and during foreseeable emergencies.
· How the company will inform the contractor of the labeling system in use. The contract should specify the contractor's responsibility for training his/her employees with regard to the hazards associated with chemicals or products to which there may be exposure.
See Appendix B for a Sample Written Hazard Communication Program.
Labeling of Hazardous Chemicals
The Michigan Right to Know Law requires that containers housing hazardous substances be labeled. The intent of the law is to ensure that employees are fully informed as to the identities of the materials they are exposed to and any inherent danger to that employee if that substance is handled. Labels provide employees with an immediate source of information and should not under any circumstances be removed or defaced. Generally speaking, it is the manufacturer's responsibility to label all hazardous chemicals shipped out of the company's facility. However, if a hazardous chemical is transferred from a large container to a smaller (secondary) container, or a label falls off, you may find it necessary to produce or update a label.
For labels on shipped containers, the chemical manufacturer, importer, or distributor shall ensure that each container of hazardous chemicals leaving the workplace is labeled, tagged or marked. Where the chemical manufacturer or importer is required to label, tag or mark, the following shall be provided:
Product identifier
Signal word
Hazard statement(s)
Pictogram(s)
Precautionary statement(s)
Name, address, and telephone number of the chemical manufacturer, importer, or other responsible party
Chemical manufacturer, importer, or distributor shall consult Appendix C which is used to determine which label elements apply to the substance. Label elements for each hazard class and associated hazard category for the hazardous chemical are to be prominently displayed and in English (other languages may also be included if appropriate).
Refer to CET# 5530, “Suggested Format for a Written Hazard Communication Program” for guidance related to labeling secondary containers.
Maintaining Safety Data Sheets (SDSs)
The SDS is a source of detailed information on a chemical or product and provides information of the hazards associated with the chemical or product. MIOSHA requires that copies of the SDSs for hazardous chemicals or products be readily accessible to employees at each work site and during each work shift. Federal law requires manufacturers and distributors of products containing hazardous substances to furnish customers with SDSs for each such substance or product. If you do not have a current SDS, you will need to request an SDS from the manufacturer.
The HCS requires chemical manufacturers, distributors, or importers to provide SDSs (formerly known as Material Safety Data Sheets or MSDSs) to communicate the hazards of hazardous chemical products. As of June 1, 2015, the HCS will require new SDSs to be in a uniform format, and include the section numbers, the headings, and associated information under the headings below:
Section 1. Identification includes product identifier; manufacturer or distributor name, address, phone number; emergency phone number; recommended use; restrictions on use.
Section 2. Hazard(s) identification includes all hazards regarding the chemical; required label elements.
Section 3. Composition/information on ingredients includes information on chemical ingredients; trade secret claims.
Section 4. First-aid measures includes important symptoms/effects, acute, delayed; required treatment.
Section 5. Firefighting measures lists suitable extinguishing techniques, equipment; chemical hazards from fire.
Section 6. Accidental release measures lists emergency procedures; protective equipment; proper methods of containment and cleanup.
Section 7. Handling and storage lists precautions for safe handling and storage, including incompatibilities.
Section 8. Exposure controls/personal protection lists OSHA's Permissible Exposure Limits (PELs); Threshold Limit Values (TLVs); appropriate engineering controls; personal protective equipment (PPE).
Section 9. Physical and chemical properties lists the chemical's characteristics.
Section 10. Stability and reactivity lists chemical stability and possibility of hazardous reactions.
Section 11. Toxicological information includes routes of exposure; related symptoms, acute and chronic effects; numerical measures of toxicity.
Section 12. Ecological information*
Section 13. Disposal considerations*
Section 14. Transport information*
Section 15. Regulatory information*
Section 16. Other information includes the date of preparation or last revision.
*Note: Since other Agencies regulate this information, MIOSHA will not be enforcing Sections 12 through 15.
Employers must ensure that SDSs are readily accessible to employees.
See Appendix D of 1910.1200 for a detailed description of SDS contents.

Glossary of Terms Used on an SDS
Acute ‑ Short term period of action. Readily apparent.
Acute Toxicity - Acute toxicity refers to those adverse effects occurring following oral or dermal administration of a single dose of a substance, or multiple doses given within 24 hours, or an inhalation exposure of 4 hours.
Asphyxiate ‑ A gas or vapor that can cause injury, unconsciousness or death by suffocation by reducing the amount of oxygen sufficient to promote life. See definition for “Simple Asphyxiant.”
Aspiration - The entry of a liquid or solid chemical directly through the oral or nasal cavity, or indirectly from vomiting, into the trachea and lower respiratory system.
Aspiration Toxicity - Severe acute effects such as chemical pneumonia, varying degrees of pulmonary injury or death following aspiration.
Boiling Point - A temperature at which a liquid turns to a vapor state. This term is usually associated with the temperature at sea level pressure when a flammable liquid gives off sufficient vapors to promote combustion.
Carcinogen ‑ A substance or a mixture of substances which induce cancer or increase its incidence. Substances and mixtures which have induced benign and malignant tumors in well-performed experimental studies on animals are considered also to be presumed or suspected human carcinogens unless there is strong evidence that the mechanism of tumor formation is not relevant for humans.
“C” or Ceiling - In terms of exposure concentrations, this is the concentration that should never be exceeded, even for a short period, for a substance.
Chronic ‑ A long time period of action.
Chronic Effect - An adverse effect with symptoms that develop or recur very slowly, or over long periods of time. See definitions for “Specific Target Organ Toxicity – Repeated Exposure (STOT-RE).” Refer to MIOSHA Part 42, 92 and 430 Hazard Communication, Appendix A for additional information.
Combustible Dust - A combustible particulate solid that presents a fire or deflagration hazard when suspended in air or some other oxidizing medium over a range of concentrations, regardless of particle size or shape. Definition from OSHA National Emphasis Program (CPL-03-00-008) on Combustible Dust as this term is not defined in MIOSHA Part 42, 92 and 430 Hazard Communication Standard.
Compressed Gas ‑ Gases which are contained in a receptacle at a pressure of 200 kPa (29 psi)
(gauge) or more.
Concentration - A figure used to define relative quantity of a particular material; such as, a mixture of 5 ppm Acetone in air.
Corrosive Material ‑ See definitions for “Corrosive to Metals” and “Skin Corrosion.” Many acids are classified as corrosives.
Corrosive to Metals - A chemical which by chemical action will materially damage, or even destroy, metals.
Decomposition - The breakdown of materials or substances into other substances or parts of compounds; usually associated with heat or chemical reactions.
Dermal - Used on or applied to the skin.
Dermal Toxicity - The adverse effects resulting from exposure of a material to the skin; usually associated with lab animal tests.
Evaporation Rate - The rate at which a liquid material is known to evaporate, usually associated with flammable materials. The faster a material will evaporate, the sooner it will become concentrated in the air, possibly creating either an explosive/combustible mixture or toxic concentration, or both.
Explosive Chemicals ‑ A solid or liquid chemical which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings. Pyrotechnic chemicals are included even when they do not evolve gases.
Exposure ‑ Contact of an individual with a hazardous material during the course of employment, through any route of entry (e.g., inhalation, ingestion, skin contact or absorption).
Eye Irritation - The production of changes in the eye following the application of test substance to the anterior surface of the eye; which are fully reversible within 21 days of application.
Flammable Gas - A gas having a flammable range with air at 20°C (68°F) and a standard pressure of 101.3 kPa (14.7 psi).
Flammable Liquid - Flammable liquid means a liquid having a flash point of not more than 93°C (199.4°F).
Flammable Solid ‑ Flammable solid means a solid that is a readily combustible, or which may cause or contribute to fire through friction.
Flash Point ‑ The minimum temperature at which a liquid gives off vapor in sufficient concentration to form an ignitable mixture with air near the surface of the liquid, as determined by a method identified in Hazard Communication Standard, Appendix B, Section B.6.3.
General Exhaust - A term used to define a system for exhausting or ventilating air from a general work area. Not as site specific as localized exhaust.
“g”, gram - A unit of weight. One ounce equals about 28.4 grams.
HMIS® - Hazardous Material Identification System - a numerical hazard rating that incorporates the use of labels with color-coded bars as well as training materials. It was developed by the American Coatings Association. The four bars are color coded, using the modern color bar symbols with blue indicating the level of health hazard, red for flammability, orange for a physical hazard, and white for Personal Protection. The number ratings range from 0-4 with 4 representing the greatest hazard.

Hazard Category - The division or criteria within a given hazard class. For example, oral acute toxicity and flammable liquids include four hazard categories. These hazard categories compare hazard severity, within a hazard class. They should not be taken as a comparison of hazard categories more generally.
Hazard Class - The nature of the physical or health hazards (e.g., flammable solid, carcinogen, oral acute toxicity).
Hazard Not Otherwise An adverse physical or health effect identified through evaluation of scientific
Classified (HNOC) - evidence during the classification process that does not meet the specified criteria for the physical and health hazard classes addressed in this section. This does not extend coverage to adverse physical and health effects for which there is a hazard class addressed in this section, but the effect either falls below the cut-off value/concentration limit of the hazard class or is under a GHS hazard category that has not been adopted by OSHA (e.g., acute toxicity Category 5).
Hazard Statement - A statement assigned to a hazard class and category that describes the nature of the hazard(s) of a chemical, including, where appropriate, the degree of hazard.
Hazardous Chemical- Any chemical which is classified as a physical hazard or a health hazard, a simple asphyxiant, combustible dust, pyrophoric gas, or hazard not otherwise classified (HNOC).
Health Hazard ‑ A chemical which is classified as posing one of the following hazardous effects: acute toxicity (any route of exposure); skin corrosion or irritation; serious eye damage or eye irritation; respiratory or skin sensitization; germ cell mutagenicity; carcinogenicity; reproductive toxicity; specific target organ toxicity (single or repeated exposure); or aspiration hazard. The criteria for determining whether a chemical is classified as a health hazard is detailed in Appendix A to Part 42, 92 and 430 Hazard Communication Standard -- Health Hazard Criteria.
Incompatible - Materials that could cause dangerous reactions from direct contact with one another.
Ingestion - Taking in of a substance through the mouth.
Inhalation - The breathing in of a substance in the form of a gas, liquid, vapor, dust, mist or fume.
Inhibitor - A chemical added to another substance to prevent an unwanted change from occurring.
Irritant ‑ A chemical substance or mixture, other than a corrosive, that when contacted with the skin produces a reversible inflammatory reaction to the affected area and/or surrounding areas. Normally, irritants affect the eyes, nose, mouth and respiratory system.
LC - Lethal Concentration - In lab animal tests, this is the concentration of a substance which is sufficient to kill the tested animal.
LC50 - Median Lethal Concentration ‑ The concentration in air of gas, vapor, mist, fume or dust for a given period of time that will kill 50 percent of the test animals using a specified test procedure. Inhalation is the primary route of entry.
LD50 - Median Lethal Dose ‑ The dosage of a substance that will kill 50 percent of the test animals to which the substance is administered using a specified test procedure. Various routes of entry can be used for testing purposes.
LEL ‑ Lower Exposure Limit - The lowest concentration of a gas or vapor in the air that will ignite or explode if an ignition source is introduced.
Mutagen ‑ A permanent change in the amount or structure of the genetic material in a cell. The term mutation applies both to heritable genetic changes that may be manifested at the phenotypic level and to the underlying DNA modifications when known (including, for example, specific base pair changes and chromosomal translocations). The term mutagenic and mutagen will be used for agents giving rise to an increased occurrence of mutations in populations of cells and/or organisms.
NFPA - National Fire Protection Association - An organization that promotes fire protection/prevention and establishes safeguards against loss of property and/or life by fire. The NFPA has established a series of codes identifying hazardous materials by symbol and number for firefighting purposes. These codes also classify materials in their order of flammability. With 0 being not burnable up to 4 which means it will burn spontaneously at room temperature.
Reference link: https://www.nfpa.org/Assets/files/AboutTheCodes/704/NFPA704_HC2012_QCard.pdf
Olfactory - Relating to the sense of smell.
Oral - Used in or taken through the mouth into the body.
Organic Peroxide - A liquid or solid organic chemical which contains the bivalent -0-0- structure and as such is considered a derivative of hydrogen peroxide, where one or both of the hydrogen atoms have been replaced by organic radicals. The term organic peroxide includes organic peroxide mixtures, containing at least one organic peroxide. Organic peroxides are thermally unstable chemicals, which may undergo exothermic self-accelerating decomposition. In addition, they may have one or more of the following properties:
(a) Be liable to explosive decomposition;
