Methyl acrylate is stored in a flammable-materials storage room or cabinet below 20°C (68°F), separated from oxidizing substances. It is inhibited with 200 ppm of hydroquinone monomethyl ether to prevent self-polymerization. It is shipped in bottles, cans, drums, or tank cars.

Many regulations found in OSHA standards include features that will minimize the scope and impact of an emergency such as a fire. For example, restrictions in 1910.106 on container sizes of flammable liquids and the amounts of these materials that are permitted to be stored outside flammable material storage cabinets are designed to limit the amount of fuel available to a fire and to extend the time before the material could become involved. 

In any evacuation procedure, standard operating procedures for closing down operations should be included, if there is sufficient time to implement them. Gas should be turned off, along with electric and other types of heaters. Valves on gas cylinders should be turned off, especially if they contain flammable or toxic materials. High voltage equipment should be turned off Closing sashes on fume hoods may be desirable. Certainly any flammable material storage cabinets should be closed. 

A flammable material storage cabinet, either built-in or free standing, shall be used for the storage of flammable materials. 

AU chemicals must be stored properly, according to compatibility. AU chemicals which pose a special hazard or risk shaU be limited to the minimum quantities needed for the short-term need of the research program, and materials not in actual use shaU be stored imder appropriate safe conditions. For example, flammables not in use shaU be kept in a flammable material storage cabinet, or excess quantities of explosives shall be stored in magazines, away from the immediate... 

A flammable material storage cabinet, either built-in or fiee standing, shall be used for the storage of flammable materials. Any other special storage requirements, such as for locked storage cabinets or safes for drugs or radioactive materials, shall be available and used. 

The OSHA regulations regarding container sizes are based on sections of the 1969 version of the NFPA Standard 30. Before returning to the topic of flammable material storage cabinets. Table 3.5 defines the various classes of flammable and combustible liquids and the maximum container sizes permitted by OSHA for each class. Table 3.5 is equivalent to Table H-12 from the OSHA General Industry Standards. Table 3.5 A provides similar data from NFPA 30-1996. Recall, however, that unless adopted by a local jurisdiction, the NFPA standards are only recommendations, not regulations. 

The purpose of a flammable material storage cabinet is to postpone the involvement of the materials within the cabinet in a fire long enough to allow persons in the immediate area to evacuate the area, or in some cases to permit the fire to be extinguished. Technically, for the cabinet to pass the 10-minute fire test according to NFPA Standard 251, the interior temperature of the cabinet should not exceed 164.1 C (325 F), aU joints and seams would remain intact during the fire, and the cabinet doors would remain closed. 

Most commercially available flammable material storage cabinets are made of metal and would have to meet at least the following specifications ... 

Wooden flammable material storage cabinets, if properly constructed according to the provisions of Section 1910.106(dX3)(iiXb) of the OSHA General Industry Standards, are also acceptable. These provisions are ... 

Storage cabinets can be obtained to serve either as flammable material storage cabinets or as cabinets for the storage of acids. In the latter case, the shelves must be provided with protection against the effects of corrosion. One of the more economical ways of achieving the required protection is to use polyethylene shelf liners. If they are not needed or need to be replaced, they can readily be taken out or can be replaced with stock polyethylene. The interior walls can be protected from the effects of acid vapors and fumes by being painted with an acid-resistant paint. 

It is possible to modify a normal home refrigeration unit to remove the internal sources of ignition, but unless it is done by a person who knows precisely what to do and does it very carefully the result may not be as safe as one initially designed to be used for flammable material storage. The liability which could result from the failure to prevent an explosion by an improperly, locally modified unit makes this an imprudent economy measure. In addition, the... 

There should be some basic emergency equipment and supplies readily available to every laboratory usirrg hazardous chemicals. It is essential that some items be available within the laboratory itself For example, in any laboratory in which flammables are stored, OSHA standards (19 10.106(dX7)(b)) require that at least one 12-B portable fire extinguisher be located not less than 10 feet nor more than 25 feet from a flammable material storage area within a building. If other types of chemicals are in use, other types of fire extinguishers should be available, such as class D units if reactive metals are stored or in use or pressurized water units if there are substantial amounts of ordinary combustible materials present.

The siting of toxic, corrosive and flammable material storage is such that they do not affect the ability of the safety significant SSCs to achieve their KSFs. This will include appropriate bunding, drainage and ventilation.
