"Purpose."

**1910.1200(a)(1)**
The purpose of this section is to ensure that the hazards of all chemicals produced or imported areevaluated, and that information concerning their hazards is transmitted to employers and employees. This transmittal of information is to beaccomplished by means of comprehensive hazard communication programs, which are to include container labeling and other forms of warning, materialsafety data sheets and employee training.

***..1910.1200(a)(2)***
**1910.1200(a)(2)**
This occupational safety and health standard is intended to address comprehensively the issue ofevaluating the potential hazards of chemicals, and communicating information concerning hazards and appropriate protective measures to employees, andto preempt any legal requirements of a state, or political subdivision of a state, pertaining to this subject. Evaluating the potential hazards ofchemicals, and communicating information concerning hazards and appropriate protective measures to employees, may include, for example, but is notlimited to, provisions for: developing and maintaining a written hazard communication program for the workplace, including lists of hazardouschemicals present; labeling of containers of chemicals in the workplace, as well as of containers of chemicals being shipped to other workplaces;preparation and distribution of material safety data sheets to employees and downstream employers; and development and implementation of employeetraining programs regarding hazards of chemicals and protective measures. Under section 18 of the Act, no state or political subdivision of a statemay adopt or enforce, through any court or agency, any requirement relating to the issue addressed by this Federal standard, except pursuant to aFederally-approved state plan.

**1910.1200(b)**
"Scope and application."

**1910.1200(b)(1)**
This section requires chemical manufacturers or importers to assess the hazards of chemicals whichthey produce or import, and all employers to provide information to their employees about the hazardous chemicals to which they are exposed, by meansof a hazard communication program, labels and other forms of warning, material safety data sheets, and information and training. In addition, thissection requires distributors to transmit the required information to employers. (Employers who do not produce or import chemicals need only focus onthose parts of this rule that deal with establishing a workplace program and communicating information to their workers. Appendix E of this section isa general guide for such employers to help them determine their compliance obligations under the rule.)

**1910.1200(b)(2)**
This section applies to any chemical which is known to be present in the workplace in such a mannerthat employees may be exposed under normal conditions of use or in a foreseeable emergency.

**1910.1200(b)(3)**
This section applies to laboratories only as follows:

Employers shall ensure that labels on incoming containers of hazardous chemicals are not removedor defaced;

***..1910.1200(b)(4)(ii)***
**1910.1200(b)(4)(ii)**
Employers shall maintain copies of any material safety data sheets that are received withincoming shipments of the sealed containers of hazardous chemicals, shall obtain a material safety data sheet as soon as possible for sealedcontainers of hazardous chemicals received without a material safety data sheet if an employee requests the material safety data sheet, and shallensure that the material safety data sheets are readily accessible during each work shift to employees when they are in their work area(s);and,

**1910.1200(b)(4)(iii)**
Employers shall ensure that employees are provided with information and training in accordancewith paragraph (h) of this section (except for the location and availability of the written hazard communication program under paragraph (h)(2)(iii)of this section), to the extent necessary to protect them in the event of a spill or leak of a hazardous chemical from a sealed container.
