Thedescriptions are restricted to gas systems using 100pound and 150 pound cylinders, ton containers, andtank cars. Regulations IntroductionThe descriptions and recommendations provided hereare based on the recommendations from the ChlorineInstitute, OSHA, and Article 80 of the UniformBuilding Code, as well as standard industry practices.Compliance with RegulationsEvery attempt has been made to assure these recom-mendations are in compliance with existing safety practices and recommendations. However, it is highly recommended that before any consideration is madeto change an existing chlorine station to make it comply with these recommendations, the changes andexisting conditions be reviewed by the local, state, or federal safety compliance agency.OSHA RegulationFederal OSHA has very few regulations that speak directly to the handling and use of chlorine. However,they can review facilities based on other organizations’existing standards and practices, such as the ChlorineInstitute recommendations. It is important toremember that the OSHA, EPA, and DOT classifica-tions have changed for chlorine gas from a compressed gas to a Poison and Inhalation HazardZone B. This change alone brings with it the appli-cation of regulations that have not been used in thepast. The past is not a key to the future.OSHA & DOT RegulationsOSHA regulation 29 CFR 1910.120 applies to thehandling of hazardous material. It is also recom-mended to review the DOT regulations 49 CFR Part 100 through 180, the NIOSH regulation of 1979 ANSIZ-177.1 as updated in 1989, and the ProcessSafety Management regulation 29 CFR 1910.119.Clean Air RegulationsAt the writing of this lesson, the new clean air regula-tions had not been completed. However, it appearsmost likely that a chlorine gas release into theatmosphere will be a violation of the clean-air act andas such the violator would be required to change theexhaust practices or face stiff fines. Gas Stations- 61-  Article 80 IntroductionArticle 80 of the Uniform Building Code is a part of theUniform Fire Code in all states where the UniformBuilding Code has been adopted. Article 80 relatesspecifically to the storage and use of hazardousmaterials. There are two types of hazards described inthe code: physical hazards and health hazards.Physical HazardsPhysical hazards (80.202) are listed as: ã Explosive and Blasting Agentsã Compressed Gasesã Flammable and Combustible Liquidsã Flammable Solidsã Organic Peroxidesã Oxidizersã Pyrophoric Materialsã Unstable (Reactive) Materials ã Water Reactive Materialsã Cryogenic Fluids O & M of Chlorine Systems- 62- WAORCAIDMTWY UTNVAZAK NMCOKSNDSDNEOK ARMOIAMNWIILMIINNY VTNHMEMDRICTMANJDEMDVANCTNKY LAALGAFLMSSC TXOHMI   WVPA Uniform Building Code (UBC)Overlap BetweenSBC and UBCOverlap BetweenSBC and BOCAStandard BuildingCode (SBC)Basic BuildingCode (BOCA)
