Flammable solvents, storing

There are other more recent examples though. In one laboratory, flammable solvents had been used in such small quantities that they required no special storage. As their use of solvents increased, however, there were eventually five-gallon cans of ether casually stored in one comer of a room. When a routine inspection by the fire department uncovered this hazard, the laboratory was forced to install proper storage. 

Both triflouroacetic acid and sulfur trioxide will cause very severe skin burns, and their vapors are extremely irritating. Sulfur trioxide is such a strong dehydrating agent that it chars organic material, and its heat of dehydration is so high that it will start a fire if spilled on wood, which could prove fatal were flammable solvents in use at the time or stored nearby. 

Earthquakes provide the ultimate test of the storage of incompatible chemicals and are sometimes followed by fires in chemical stores. Very few causes of ignition are found alkali metals halogen oxysalts in conjunction with strong acids and sulphuric or nitric acid and cellulose (wood flooring). These usually then ignite vapours of flammable solvents. 

A conveniently situated, modest-sized (approximately 120-square-foot) storage area would suffice and it should be smooth, light colored, linoleum floored with Formica type shelving, non-heated, and dry. (Bear in mind that some sampling kits contain flammable solvents.) The store should be lock-able and under the directed control of an appointed officer and used exclusively for the storage of suspect sampling materials for use at that location only. There must be a strict accounting system for all materials. 

Where flammable solvents and adhesives are used, they must be stored, handled, and used in a manner preventing any possibility of ignition. Proper safety containers, storage areas, and well-ventilated workplaces are required. 

Chemicals and solutions to be stored at low temperatures must be in stoppered or sealed vessels. Do not store aqueous solutions below 0°C since freezing can occur and, with the resulting expansion of the volume, the vessel may crack. Solutions containing flammable solvents should only he stored in specialized spark-proof fridges consult your laboratory instructor. 

Disposal of flammable solvents in storm sewers or sanitary sewers is, in general, not allowed. Exceptions are small amounts of those materials that are miscible with water, but even disposal of these should be followed by large amounts of cold water. Other solvents should be collected in safety cans. Separate cans should be used for ether and for chlorinated solvents all other solvents may be combined in a third can. The cans should be stored, in keeping with storage quantity rules, in a safety cabinet until pickup by a waste-disposal firm. A more economical approach is to transfer the solvents to larger cans or drums in an outside storage facility so that pickup could be less frequent. Some large institutions have their own in-house disposal facilities. 

DISPOSAL AND STORAGE METHODS mix with flammable solvent and inject at base of incinerator with after-burner solid acid may be packaged in paper and burned in incinerator store in a cool, dry, well-ventilated loeation store away from heat, oxidizers, and sunlight outside or detached storage preferred. 

DISPOSAL AND STORAGE METHODS add with stirring to strong alkaline solution of calcium hypochlorite let stand 24 hours, route to sewage plant dissolve in flammable solvents and spray into incinerator with afterburner and scmbber outside storage preferred store in cool, dry, well-ventilated location isolate from oxidizing gases, especially chlorine. 

DISPOSAL AND STORAGE METHODS store in cool, dry, well-ventilated location away from sources of ignition and contact with oxidizing materials absorb onto thick layer of sand-soda ash mixture and place in a sanitary landfill dissolve in flammable solvent and bum in incinerator with afterburner and scrubber. 

DISPOSAL AND STORAGE METHODS absorb liquids containing anisidine in ver-miculite, dry sand or earth, and place in a sanitary land-fill cover o-anisidine wifh a combination of 9 parts sand to 1 part soda ash mix and transfer all material in a paper carton bum the carton in an open furnace with a scrubber and afterburner o-anisidine may be dissolved in a flammable solvent (e.g. alcohol) and atomized in a suitable combustion chamber store both isomers in a cool, dry location keep o-anisidine and p-anisidine away from heat and open flame for p-anisidine, provide general or local exhaust ventilation and dilution. 

DISPOSAL AND STORAGE METHODS absorb in dry earth or. sand, and dispose of in a secured sanitary landfill dissolve in a more flammable solvent and atomize in a suitable combustion chamber store in a cool, dry location with adequate ventilation keep away from heat, flame, and strong oxidizers. 

DISPOSAL AND STORAGE METHODS dissolve in a flammable solvent and bum in a chemical incinerator equipped with an afterburner and scrubber disposal must be in accordance with federal, state, and local regulations store in a cool, dry place maintain adequate ventilation store only with compatible chemicals separate from oxidizing materials keep in tightly closed containers outside storage is preferred. 

DISPOSAL AND STORAGE METHODS mix with a flammable solvent (such as alcohol) and bum in chemical incinerator equipped with afterburner and scrubber store in a cool, dry location outside storage preferred inside storage should be in a standard flammable liquids storage room or eabinet isolate from oxidizing materials, nitric acid and sulfuric acid.
