American National Standards hazards

There is no mention that a prior hazard assessment will be acceptable. It is only common sense that OSHA would not expect employers with a previously documented hazard assessment program that meets the new requirements to perform another assessment. Yet there is no way of knowing if this will be acceptable. Employers should use good judgment on what is an effective hazard assessment. Bear in mind, hazard assessment should incorporate any applicable American National Standards...

Injuries and fatalities from asphyxiation are often associated with personnel entry into inerted equipment or enclosures. Guidance on safe procedures for confined space access are provided by OSHA (OSHA, 29 CFR 1910.146, Confined Space Entry Standard, 2000), the American National Standards Institute (ANSI, Z117.1, Safety Requirements for Confined Spaces, 2003), Hodson (Hodson, Safe Entry into Confined Spaces, Handbook of Chemical Health and Safety, American Chemical Society, 2001), and BP (BP, Hazards of Nitrogen and Catalyst Handling, 2003). OSHA has established 19.5 vol % as the minimum safe oxygen concentration for confined space entry without supplemental oxygen supply (see Table 23-18). Note that OSHA imposes a safe upper limit on 02 concentration of 23.5 vol % to protect against the enhanced flammability hazards associated with 02-enriched atmospheres. 

To support a GDC citation, OSHA must establish employer or industry recognition of a hazard. Among other forms of evidence, industry recognition may be demonstrated by a consensus standard (NFPA, American National Standards Institute [ANSI], American Petroleum Institute [API], American Society for Testing and Materials [ASTM], etc.). Industry standards may also be used to identify feasible means of reducing the hazard. However, no industry consensus standard has been identified for the management of reactive hazards in support of a GDC citation.43...

The SCHC strives to keep its members aware of the latest developments concerning hazard communication. Topics at meetings include Internet resources American National Standards Institute (ANSI) Standards Environmental Protection Agency, Department of Transportation (DOT), and Occupational Safety and Health Administration (OSFLA) updates and international information. A major topic has been the international harmonization of hazard communication, the Globally Harmonized System (GHS) of Classification and Labeling of Chemicals. The development of the system was completed in 2001, adopted/endorsed by the UN in 2002, and is expected to affect hazard communication globally. 

An authoritative guide to the safety labeling of hazardous materials and products is issued by the American National Standards Institute. See toxicity flammable material label. 

General equipment Other equipment, such as face shields (American National Standards Institute Standard Z87.1), bottle and flask carriers, etc., may be required at times. Hood windows should be lowered for control of toxic fumes and when handling otherwise hazardous material in the hood. Assure that a hood is functioning properly by use of an airflow measurement device. 

The American National Standards Institute (ANSI) has established a voluntary standard for chemical labeling, ANSI Z129.11994, Hazardous Industrial Chemical Precautionary Labeling, which includes readily identifiable symbols for poisons, corrosives, flammables, and explosives. Irritants, combustible liquids, pyrophoric chemicals, oxidizers, sensitizers, physiologically inert vapors, gases and other hazardous materials are also addressed. 

This nomenclature is specialized to trademark practitioners. Thus, for example, the American National Standard on labelling hazardous industrial chemicals states that identification of a hazardous product or component should not be limited to a nondescriptive trade name . This recommendation obviously is designed to include trademarks. 

Appendix B is not a part of the American National Standard for the Precautionary Labeling of Hazardous Industrial Chemicals, Z129.1-1982, but is included for information purposes only. Because of the widespread interest in chronic hazards, it is reproduced below. 

The acute effects referred to most frequently are those defined by the American National Standards Institute (ANSI) standard for Precautionary Labeling of Hazardous Industrial Chemicals (Z129.1-1982)—irritation, corrosivity, sensitization and lethal dose. Although these are important health effects, they do not adequately cover the considerable range of acute effects which may occur as a result of occupational exposure, such as, for example, narcosis.

The American National Standards Institute (ANSI) was founded in 1918 and has been the administrator and coordinator of the United States private sector voluntary standardization system (see website http //www.ansi.oig). ANSI does not itself develop standards but rather facilitates development by establishing consensus among qualified groups. ANSI has developed a number of occupational health-and safety-related standards, including standards related to information management for occupational safety and health (ANSI Z16.2-1995), preparation of hazardous industrial chemiceil materi safety... 

The MSDS must show the identity of the chemical on the label. For a single substance, the MSDS identifies its chemical and common name. If the chemical is a mixture, the MSDS must show the common name of the mixture and the chemical name or common names of ingredients which contribute to known hazards. Because MSDSs are so important to the HAZCOM process, the HAZCOM standard establishes detailed requirements for information that is needed on them. To illustrate this information, a commonly used MSDS format, the American National Standards Institute (ANSI) format (see Table 14-1) will be described. This format was developed by the Chemical Manufacturer s Association (CMA) and approved by ANSI.
