Leaks methyl chloride

Alcohol consumption increases toxic effects. Turn leaking cylinder so that leak is on top to prevent liquid methyl chloride escaping. 

Under no circumstances should water or other materials be introduced into tank cars which contain, or have contained, methyl chloride. Soapy water should be used to test for leaks, but glycerine should be used in freezing weather or around very cold pipes or equipment. An open flame must never be used to test for leaks on any containers holding methyl chloride. 

When unloading tank cars, and a leak occurs that cannot be readily repaired by simple adjustment or tightening of the fittings, call the methyl chloride manufacturer at once for instruction, and evacuate the area around the car immediately. Permit only properly protected and instructed personnel to enter the contaminated area. 

If a TMU container leaks, all sources of ignition must be removed from the area at once, and if the leak cannot be stopped, transfer the methyl chloride to another container. Obtain and follow the detailed instructions of the methyl chloride manufacturer or supplier. 

Use methyl chloride in a well-ventilated area only, preferably using a hood with forced ventilation. The cylinder should never be directly connected to a container of liquid since reverse flow can occur causing a reaction within the cylinder. To prevent reverse flow, a trap, check valve, or vacuum break should be inserted into the line. Cylinders of methyl chloride should be stored and used only in well-ventilated areas away from heat and all sources of ignition such as flames and sparks in order to avoid fire and explosion hazards. Flames should never be used to detect methyl chloride leaks use a soapy water solution. Do not use methyl chloride around sparking motors or other nonexplosion-proof equipment. Reserve stocks of methyl chloride cylinders should not be stored with... 

Methyl chloride may be absorbed from leaking cylinders into a suitable organic solvent such as xylene, toluene, benzene, or chloroform after attachment of the appropriate regulator and flexible tubing. It may subsequently be recovered for use, or it may be disposed of in a manner suitable for disposal of a flammable gas and in accordance with federal, state or provincial, and local regulations [4]. 

In detecting leaks, it is advisable to transfer the methyl chloride vapor or liquid from refrigerating units into gastight containers before testing the units for suspected leaks. The units may then be placed under carbon dioxide, air, or nitrogen pressure and tested by the application of soapy water (or glycer-...
