Storage flammable-combustible materials

Storage Segregated storage Uncongested storage of combustibles gangways/adequate breaks Material stacked in the open should be away from windows Flammable liquids in properly designed storerooms bulk quantities in fixed, bunded, adequately spaced tanks... 

Laboratories are normally classified nonhazardous locations if the quantities of flammable and combustible liquids are within the requirements of NFPA. Normally a vapor collection hood is provided when sampling and measurements are conducted with exposed liquids. The primary concern is the exhaust of vapors and the storage and removal material saturated with liquids. The exhaust hood, ducting and a radius of 1.5 meters (5 ft.) from the exhaust vent should be considered an electrically classified area. 

Damaging fires are uncontrolled chemical reactions, so fire hazards involving ordinary flammable and combustible materials could be included in the above definition of chemical reactivity hazards. However, this publication seeks to supplement basic fire prevention and protection measures by addressing how to successfully manage other chemical reactivity hazards in the work environment. Consequently, the use of the term "chemical reactivity hazards" in this publication will not include explosion, fire and dust explosibility hazards involving the burning of flammable and combustible materials in air. Storage and use of commercial explosives is also outside the scope of this publication. 

Flammable liquids and solids are subdivided according to their flash points and many oxidizing substances can cause fire when in contact with combustible materials. Storage, handling and disposal are obviously major features to be considered when using such substances. 

Waste disposal of infectious specimens, contaminated materials, and chemicals must be in compliance with local, state, and federal (EPA) regulations. Flammable safety cabinets are required for storage of alcohols, xylenes, and other combustible materials. 

Storage of large volumes of flammable or combustible materials is separated from high value operating or processing areas and personnel occupancies. 

Fired process heaters and boilers, incinerators, flares, and other equipment with flame burners are located at an appropriate distance from high value operating or processing areas, large volume storage of flammable or combustible materials, control rooms, operating offices, and their occupants. 

In order to estimate the duration of potential fires, it is necessary to identify inventories that can be isolated. An inventory of flammable and combustible materials should be developed for each process unit and storage area within a facility. This list should contain the quantity, storage configuration, material characteristics, and location. 

Underwriters Laboratories (UL) also approves and rates storage tanks. Factors including tank wall thickness, type of metal used, welding procedure, venting, supports, pressure ratings, and other related topics are specifically defined in the approval codes. Guidelines which relate directly to the storage of flammable and combustible materials are provided under UL Code 142. 

Commercial use of ethanol fuel is regulated by NFPA 30, Flammable and Combustible Material Code. For ethanol storage and dispensing systems, the NFPA 30A, Automotive and Marine Service Station Code, would apply. 

Design liquid storage so leaks and spills do not accumulate under tanks or process equipment Use open structures for plants using flammable or combustible materials Avoid buried tanks... 

It is a good idea to design dikes that will not allow flammable or combustible materials to accumulate around the bottom of storage tanks or process equipment in case of a spill. If liquid spills and ignites inside a dike where there are storage tanks or process equipment, the fire may be continuously supplied with fuel and the consequences can be severe. It is usually much better... 

Do not store paper, cardboard, or other combustible material in or on a flammable liquid storage cabinet.
