The law requires the OSHA standard to cover at least 14 areas or issues and to cover highly hazardous chemicals which include toxic, flammable, highly reactive and explosive substances. The paper will describe in detail how OSHA has responded to this statute and what we have accomplished in the rulemaking effort. Also the interface with other relevant OSHA standards, including the Hazard Communication standard, the Hazardous Waste Operations and Emergency Response standard, the Control of Hazardous Energy Sources (Lockout/Tagout) standard, and others will be discussed. In addition other recent laws that relate to and impact the OSHA PSM standard such as the Hazardous Materials Transportation Uniform Safety Act of 1990, the Oil Pollution Act of 1990, and the Superfund Amendments and Reauthorization Act (SARA) of 1986, will be explained as to their relationship to PSM. The emergency preparedness efforts required of employers under PSM and the relationship to SARA Title III efforts by local community emergency response organization will be covered, as well as the interface with the EPA Risk Management Program initiative that EPA must do under the Clean Air Act Amendments.","PeriodicalId":364732,"journal":{"name":"Plant\\/operations Progress","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128187876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that thermodynamic availability is a completely general approach, including effects due to chemical reaction and mechanical expansion. For the case of a non-reactive gas, a general equation is presented to determine the energy of explosion due to mechanical expansion of the gas. The energy determined using availability is much less than the energy determined assuming an isothermal expansion and usually much more than the energy determined assuming an isentropic expansion. Since availability is a state function, the energy determined is independent of the path.","PeriodicalId":364732,"journal":{"name":"Plant\\/operations Progress","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131295188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The managers involved (and typically the majority of managers working in a chemical plant will be actively involved in safety issues) have to work to strike a balance between many conflicting pressures. Examples of such factors include profitability, production targets, legislation, the workforce and the environment. Sometimes there is an ideal solution where an alternate engineering design can completely eliminate the risk of a major accident. However, more often than not, even after design modifications, there will be finite risk of a major accident. The successful risk management policy will result in an acceptable balance between the driving pressures of the business and decreasing risk. The balance might be sought considering both local and federal governments, the public, the media, the company workforce, the environment, the relevant insurance company and the financial interests of the business. An essential part of the risk management process is optimizing the use of the available safety budget. A large budget could very easily be spent with no significant increase in safety if the wrong decisions are made regarding priorities in design changes or plant modifications.

The primary cause of the incident is believed to have been a fuel rich SVG stream that was rapidly introduced into the incinerator creating a “puff.” This “puff” allowed flame from the natural gas ring burner to blow back into the windbox igniting the fuel rich SVG. The combustion of gas in the ducting then created a pressure wave that blew apart the flame arrestor and caused the remainder of the damage.","PeriodicalId":364732,"journal":{"name":"Plant\\/operations Progress","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122630468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
