Claim:
A chemical loading system for loading a molten chemical into a tanker, the chemical loading system comprising: a source supplying a molten chemical; a tanker for receiving the molten chemical; a stationary feed line supplying the molten chemical from the source; an extendable loader assembly having a feed passage in fluid communication with the stationary feed line, the extendable loader assembly having a retracted position and an extended position relative to the stationary feed line, the feed passage being adapted to have at least a portion thereof inside the tanker when the extendable loader assembly is in the extended position; a hoist assembly that selectively extends and retracts the extendable loader assembly between the retracted and extended position; wherein the extendable loader assembly further comprises a ventilation passage in fluid communication with the interior of the tanker when the extendable loader assembly is in it extended position; and wherein the ventilation passage moves in unison with the feed passage when the extendable loader assembly is moved between its extended and retracted positions.
