HAZARD COMMUNICATION

Hazard Communication Standard 29CFR1910.1200(a)(1)

“The purpose of this section is to ensure that the hazards of all chemicals produced or imported are evaluated, and that information concerning their hazards is transmitted to employers and employees. This 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, material safety data sheets and employee training.” OSHA

Your workplace must provide you with:

A written hazard communication program A list of the hazardous chemicals onsite MSDSs for those chemicals Training: How to recognize, understand, and use labels and MSDSs How to use safe procedures that protect you against exposure

MSDS REQUIREMENTS

•

The MSDS must meet all of the minimum requirements found in: 29 CFR 1910.1200(g)

All Names: product, generic, compound, other, etc. (g)(2)(i)… • Name of Responsible Party (manufacturer, importer, responsible person) • Physical & Chemical characteristics of the hazardous chemical (such as vapor pressure, flash point);(g)(2)(ii) • The physical hazards of the hazardous chemical, including the potential for fire, explosion, and reactivity; (g)(2)(iii) • The health hazards of the hazardous chemical, including signs and symptoms of exposure, and any medical conditions which are generally recognized as being aggravated by exposure to the chemical;(g)(2)(iv) • Primal route of entry (g)(2)(v) • The OSHA permissible exposure limit, ACGIH Threshold Limit Value, and any other exposure limit used or recommended by the chemical manufacturer, importer, or employer preparing the material safety data sheet, where available; 1910.1200(g)(2)(vi) (PEL and the TLV) • Any generally applicable precautions for safe handling and use which are known to the chemical manufacturer, importer or employer preparing the material safety data sheet, including appropriate hygienic practices, protective measures during repair and maintenance of contaminated equipment, and procedures for clean-up of spills and leaks; 1910.1200(g)(2)(viii).

EXERCISES Review the MSDS for: Hydrofluoric Acid Chlorine Benzene Formaldehyde

MSDS EXAMPLE

Hydrogen Fluoride

Hydrogen Fluoride, also known as hydrofluoric acid (HF), is an inorganic acid mainly used for producing fluorine-containing materials such as refrigerants, pharmaceutical intermediates and fluoropolymers. Other uses include metals manufacturing, glass etching and polishing, production of gasoline, stainless steel pickling, semi-conductor preparation and various applications in the chemical and specialty metal production industries.

Section Three:

Hazard Identification

EMERGENCY OVERVIEW: Clear, colorless, corrosive fuming liquid with an extremely acrid odor. Forms dense white vapor clouds if released. Both liquid and vapor can cause severe burns to all parts of the body. Specialized medical treatment is required for all exposures.

MSDS SECTIONS

What are the Potential Hazards of HF?

• •

Potential Health Hazards: Route of

Exposure

• • Skin Hazards Eye Hazards Inhalation Hazards: Mild & Severe Exposure listed • Ingestion Hazards Delayed Effects: Concentration & Delay of Symptoms

HOW CHEMICALS AFFECT YOUR BODY

Exposure to chemicals can be:

• • Acute (short term)( Acid on skin) Chronic (long term)(Leukemia from Benzene)

Dose

– it depends on the amount you’ve received

Duration

– and the length of time exposed, one-time or repeated exposure

MSDS : SECTION 4

First Aid Measures

• • • • • Skin: After Thoroughly washing for at least 5 minutes, the burned area should be immersed in a solution of .13% iced aqueous Zephiran Chloride until pain is relieved… Eyes… Inhalation… Ingestion….

Special Section: advise Physician on “Recommended Medical Treatment for Hydrofluoric Exposure…”

EXAMPLE: SECTION 4

Note:

Industrial clients (including the manufacture) will often have special emergency response teams that are prepared to respond to a medical emergency involving chemicals.

The Global System for Hazard Communication. Background RESOURCES

Link: http://www.osha.gov/dsg /hazcom/ghs.html#1.1 • 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.

• The United States was an active participant in the development of the GHS, and is a member of the UN bodies established to maintain and coordinate implementation of the system.

Review and compare differences between the MSDSs for Chlorine, Benzene & Formaldehyde.

Which MSDS has more information and which one has the least information?

Which one, if any, requires the least amount of PPE for general operations? For a spill, which MSDS provides you the most detail on mitigating the hazards? In your opinion, which substance is more toxic?

Would feel comfortable using only the information provided in the MSDS?
