is the emptying of buckets
of human waste
when the cells
are unlocked in prisons
in the morning. Inmates without a toilet
in the cell have to use a bucket or chamber pot
while locked in during the night. The reasons that some cells do not have toilets is that they are easily smashed; to prevent this metal toilets have to be installed, but they are expensive.
In the United Kingdom, slopping out was supposed to have been phased out, but some prisons, such as HMP Peterhead have not been able to afford to.
