Unloading

Unloading procedures are exactly the same as loading precautions - e.g. products which are hazardous to humans must be unloaded in a sealed environment, with unload and vapour return pipes, protective clothing and breathing apparatus.

Cleaning

As mentioned before, the following types of tankers are never cross-used :-
  • chemicals and food
  • liquid chemicals and granules and gases
The cleaning of a tank depends on whatever it has carried. After discharge, tankers are taken to specialist cleaning stations, so that the products, which may be acidic or alkaline, can be neutralised and disposed of in an environmentally friendly way. Specific reagents may be needed to break down and rinse out the chemicals. Some products may have to be burned away at specialist disposal sites.

But if a tanker is to be used to load the same chemical straight away, then cleaning is not always necessary.
