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.
The Hierarchy of Occupational Exposure Limits, of which occupational exposure banding is a member. Occupational exposure banding, also known as hazard banding, is a process intended to quickly and accurately assign chemicals into specific categories (bands), each corresponding to a range of exposure concentrations designed to protect worker health.
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.
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 ...
Secondary containment (meant to trap the petrol in a retaining wall around the tank) failed and allowed petrol to flow out. Tertiary containment (drains and catchment areas to prevent release of spilled chemicals to the environment) also failed, and fuel and firefighting foam entered groundwater supplies.
The National Electrical Code (NEC), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States. It is part of the National Fire Code series published by the National Fire Protection Association (NFPA), a private trade association . [ 1 ]
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.
