Transport of Bulk Chemicals : Ideally only sufficient concentrated acids, flammable solvents and other hazardous chemicals should be kept in the laboratory for immediate requirements. Larger amounts, e.g. 500 cm³. 1 litre and 2 litre (Winchester) bottles, carboys and metal drums, should always be kept in a separate store. Acid resistant trays or troughs are required for the storage of concentrated sulphuric, nitric and other acids. They are also useful for storing all liquids as the tray will contain any bottle which breaks and thus prevent harmful liquids sorting into shelves and spilling over onto other containers or onto the floor.

Never carry Winchesters by the neck as the bottle can easily slip out of your hand and smash on the floor; and don't carry these bottles in the arms or in the hands. A proper carrier must always be used for transporting Winchesters from the store or from one lab to another.

Carboys of concentrated acids and other liquids should be vented otherwise, the increase in pressure as the contents heat up on being brought from a cold store into a warm room is sufficient to burst the carboy. Whenever possible, carboys should be left in the bulk store and liquids transferred as required using a carboy siphon, Figure.

How many Winchesters do you think it is safe to carry in one arm:

i) one

ii) two, or

iii) none?

And would you hold them ivy by the neck, or

v) at the base?
