STORAGE & HANDLING
How To Check Smokeless Powder For Deterioration
Although modern smokeless powders are basically free from deterioration under proper storage conditions, safe practices require a recognition of the signs of deterioration and its possible effects.
Powder deterioration can be checked by opening the cap on the container and smelling the contents. Powder undergoing deterioration has an irritating acidic odor. (Don't confuse this with common solvent odors such as alcohol, ether and acetone.)
Check to make certain that powder is not exposed to extreme heat as this may cause deterioration. Such exposure produces an acidity which accelerates further reaction and has been known, because of the heat generated by the reaction, to cause spontaneous combustion.
Considerations For Storage Of Smokeless Powder
Smokeless powder is intended to function by burning,
so it must be protected against accidental exposure to flame, sparks or
high temperatures.
For these reasons, it is desirable that storage enclosures be made of insulating materials to protect the powder from external heat sources.
Recommendations For Storage Of Smokeless Powder
STORE IN A COOL, DRY PLACE. Be sure the storage area selected is free from any possible sources of excess heat and is isolated from open flame, furnaces, hot water heaters, etc.
Do not store smokeless powder where it will be exposed to the sun's rays. Avoid storage in areas where mechanical or electrical equipment is in operation. Restrict from the storage areas heat or sparks which may result from improper, defective or overloaded electrical circuits.
