Chemical Forums: urgent:aspects of storing acetone(vapors, corrosion,HDPE

I am writing as I need urgently to store acetone into a container but I have the following doubts:

1-Acetone is almost always sold into HDPE(number 2) plastic bottles(this should be a proof for safety), but in some forums I have read HDPE plastic is not suited for acetone, as this latter will corrode it. Of course glass is better, but how good is hard rigid white plastic known as HDPE?


Regarding flammability: Is safe enough, once the liquid is stored, a simple stopper or the bottle as to be absolutely 100% airtight hermetic closed if the container is going to be keprt into a fresh site?

I am asking this as I have heard that vapors can cause, alone, with a single near spark, a fire. If the answers to these questions are yes, then I ask: if buying a kitchen glass container/bottle for food with a pressure metal cap/top: is safe if SEALING borders WITH SILICONE?


Thanks for your valuable answers
