Secondary spill containment is the containment of hazardous liquids in order to prevent pollution of soil and water. Common techniques include the use of spill berms to contain oil -filled equipment, fuel tanks , truck washing decks, or any other places or items that may leak hazardous liquids.
In the US, the independent National Fire Protection Association (NFPA) publishes several relevant standards, and they are often adopted by government agencies. Guidance on assessment of hazards is given in NFPA 497 (explosive gas) and NFPA 499 (dust). The American Petroleum Institute publishes analogous standards in RP 500 and RP505.
Secondary containment: A system to contain a hazardous material should the primary means of containment (container) fail, e.g. by leakage. The secondary container is required to hold 110% of the capacity of the primary container. Secondary fire: UK classification for a fire not involving property, e.g. rubbish or grass.
1-inch hose with 1-8 NH NFPA threads (NFPA 1963 requirement; a.k.a. "Chemical Hose Thread" and "Booster Hose Thread" [7]; the chemical hose thread term likely originates from its use on chemical fire engines, an early firefighting device used from 1872 until the 1930s that used a combination of bicarbonate of soda and sulfuric acid to force ...
The typical profile of a vessel with secondary containment is a primary vessel with an exterior vessel shell encompassing the primary vessel with at least 100% capacity. Secondary vessels are available in polyethylene, fiberglass and metal materials. Secondary containment tank systems are suggested for all aggressive chemicals.
A spill pallet is a bunded secondary containment item that is designed to hold containers of oil, hazardous liquids, and fuels, typically in either a 200-litre (44 imp gal; 53 US gal) drum or in an intermediate bulk container. It is called a 'secondary containment item' because it is designed to catch the leaks and spill of the container's ...
The International Code Council (ICC) developed fire code requirements to provide adequate protection to the building and occupants. [31] These codes specify the combustibility rating for materials, the entrance and exit requirements, as well as active fire protection requirements, along with numerous other things.
RIT ensures that in the event of a fire, the room's containment is sufficient to ensure the effectiveness of the suppression system. RIT works by creating pressure within the room or enclosure where the suppression system has been installed and ensuring that the gas does not escape from the room so quickly that it is unable to extinguish the fire.
