    Significance and Use

    5.1 The U.S. Occupational Safety and Health Administration (OSHA) in 29 CFR 1910.1000, Subpart Z, designates that certain gases and vapors present in work place atmospheres must be controlled so that their concentrations do not exceed specified limits. Other countries have similar regulations.

    5.2 This practice will provide a means for the measurement of airborne concentrations of certain gases and vapors listed in 29 CFR 1910.1000 and in other countries’ regulations.

    5.3 A partial list of chemicals for which this practice is applicable is presented in Appendix X1 with current National Institute for Occupational Safety and Health (NIOSH) recommended exposure limit (REL) values (2) and typical measurement ranges for the selected chemicals as obtained from various manufacturer’s specifications. This list is for guidance purposes only; the user of this practice is responsible for determining the applicability of commercially available tubes to specific exposure limits.

    5.4 This practice may be used for either personal or area monitoring.

    1. Scope

    1.1 This practice describes the detection and measurement of time weighted average (TWA) concentrations of toxic gases or vapors using length-of-stain colorimetric dosimeter tubes. A list of some of the gases and vapors that can be detected by this practice is provided in Appendix X1. This list is given as a guide and should be considered neither absolute nor complete.

    1.2 Length-of-stain colorimetric dosimeters work by diffusional sampling. The results are immediately available by visual observation; thus no auxiliary sampling, test, nor analysis equipment are needed. The dosimeters, therefore, are extremely simple to use and very cost effective.

    1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
