Claim:
A chemical loading system for loading a molten chemical into a tanker, the chemical loading system comprising: a source for supplying the molten chemical to the tanker; a stationary feed line for 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, wherein the extendable loader assembly further comprises a ventilation passage that is operable to be in fluid communication with the interior of the tanker when the extendable loader assembly is in its extended position; feed seals positioned between the stationary feed line and the feed passage; a hoist assembly that selectively extends and retracts the extendable loader assembly between the retracted and extended positions; and a hood with an opening through which the feed passage extends, the hood adapted for enclosing an opening of the tanker when the extendable loader assembly is in its extended position, wherein the ventilation passage does not traverse the hood.
