    1,3-butadiene monomer undergoes thermally initiated, reversible dimerization / trimerization reactions with essentially the same kinetics in both the gaseous and liquid phases.

    It is mandatory to have fire water in an operational refinery or plant according to NFPA regulatory codes. Any plant emergency may not be adequately reacted to and overcome if there is no fire protection and fire water system. Facilities can prepare the appropriate amount of fire water by deciding on the worst-case scenario in case of a plant emergency.

    On October 18, 2007, OSHA published a directive for inspection of workplaces that create or handle combustible dusts. On March 3, 2008, OSHA reissued this directive “to increase its enforcement activities and to focus on specific industry groups that have experienced either frequent combustible dust incidents or combustible dust incidents with catastrophic consequences.”

    Reactive chemicals are materials capable of giving rise to an uncontrolled chemical reaction (a.k.a., a runaway reaction). Reactions with a significant release of heat, gas and/or toxic materials have the potential to cause harm to people, property or the environment.

    The OSHA Process Safety Management National Emphasis Program will soon apply to the chemical industry, targeting compliance with safety standards associated with chemical hazards. The U.S. Occupational Safety and Health Administration's (OSHA) process safety management (PSM) standard sets requirements for the management of hazards associated with processes that use highly hazardous chemicals (HHC) - e.g., chemicals that are toxic, reactive, flammable or explosive.

    The potential for pressure relief valve instability (chattering) is a known hazard. Because of this, relief systems design basis documentation must demonstrate expected stable pressure relief valve (PRV) operation and performance for a multitude of credible scenarios.

    After much anticipation, the new 2013 Edition of NFPA 654, Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing and Handling of Combustible Particulate Solids, has finally been issued. This is one of the key standards utilized for safe handling of combustible solids.

    Information that can reveal the root cause of an incident resides in many places ― within the plant or process unit, and in control rooms, offices and witnesses' minds. Here's how to find the data and conduct effective witness interviews. Readers who were listening to the radio or watching television on the morning of February 1, 2003, will remember the loss of the Space Shuttle Columbia over Texas. Within an hour of losing contact with the Columbia, NASA's Mission Control declared a "contingency" to ensure that all mission data were preserved. All flight controllers had to verify that their logs were up-to-date and institute a hands-off policy with regard to switches, push-buttons, controllers, knobs and the like; all computer data were impounded. This was the start of NASA's investigation procedure.
