Regarding Flammable chemicals warehouse (in a pharmaceutical manufacturing plant):
Is it required that a sampling room dedicated for the flammable chemicals warehouse (for Raw material QC purpose) be present or this is only recommended?
Or
It is sufficient to use the sampling room which is used for sampling non-flammable chemicals of the neighbor non-flammable chemicals warehouse also for sampling chemicals of the flammable chemicals warehouse (i.e. using this sampling room as a common sampling room for both neighbor warehouses)?
Or
Sampling can be done from the flammable chemical drum inside pharmaceutical production room?
And Please mention the specific references (in detail) which mentioned this issue including GMP Guidelines, HSE standards and other references (if any)
