  • A Cost-Effective Approach to Explosion Consequence Modeling

    Failure to identify and mitigate explosion hazards is a persistent cause of industrial accidents, impacting sites ranging from fertilizer storage facilities to refineries. While some explosion consequence assessments are performed to comply with regulatory requirements or industry-specific process safety standards, in many cases the potential for loss of life and property damage is overlooked ...

  • Decrease of total activity with time at long distances from a nuclear accident or explosion

    Two data groups were analyzed: (1) the exposure rate in the former Czechoslovakia after the Chernobyl accident in 1986, and (2) the decrease of beta activity of an atmospheric fallout sample taken in Bratislava during 24 h on 30 May 1965. Both quantities decreased with the first power of time. This pattern of decrease is explained by applying the same mathematical formalism as is also used to ...

  • Forensic engineering applied to the analysis of a gas explosion in a residential building

    Present paper deals with the identification of the cause of an explosion in a hollow space positioned below a residential building as the result of welding operations. On field investigation clearly demonstrated that the explosion was due to the ignition of a flammable atmosphere in the basement of the building. Along the trial two hypotheses were brought to the judge: (a) explosion of an ...

  • Read about Confined Space in Construction and Atmospheric Testing Right Here!

    In 1993, 29 CFR 1910.146 went into effect as the first federal legislation governing entry into permit-required confined spaces in general industry. Because some industries, such as the construction industry, were covered by specific Occupational Safety and Health Administration (OSHA) safety regulations, they were exempt from the confined space entry requirements of the general industry rule. ...

  • Classifying Hazardous Areas

    The IEC is composed of approximately 40 countries including the United States. The purpose of the IEC is to establish standards for a wide variety of electrical products with the intent of encouraging international trade. The IEC has assigned a technical committee, TC 31, to develop recommendations covering equipment, testing procedures and classification standards for areas where the potential ...

  • Lighting the way for disinfection - Case study

    Pharmaceuticals manufacturing involves the handling of powders and volatile, flammable solvents such as iso-propanol. Consequently there is every opportunity for explosive atmospheres to form. Where this is the case, the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) require that new equipment and protective systems must be selected on the basis of the requirements set ...

  • Using plume rise schemes to model highly buoyant plumes from large fires

    The atmospheric dispersion model Numerical Atmospheric-dispersion Modelling Environment (NAME) is used to simulate the smoke plume from the explosion at the Buncefield oil depot. Simple modelling, in which the plume rise is included through an effective elevated source term, captures the transport and spread of the plume well. More complex modelling, using the NAME plume rise scheme, ...

  • Safety implications In the Waste industry following implementations of Atex directives

    Summary: Introduction of ATEX Directives 95 and 137 in July 2003 increased pressure on all industries dealing with potentially explosive atmospheres, including the waste industry. Both the equipment and the operating procedures had to be reviewed in order to comply with the directives. ATEX is the acronym of French words ATmosphere Explosives. In the UK, although the Dangerous Substances and ...

  • Investigation of an LPG accident with different mathematical model applications

    An LPG (liquefied petroleum gas) storage accident was reconstructed through several simulation models, with the aims of the reported and filmed effects and damage. The accident happened in Paese, near Treviso (Italy) in March 1996 and was characterised by complex phenomena due to a choked release of LPG from a tanker. There was a dispersion of light winds and, after about 40 minutes, a flash-fire ...
