Practice question · Put in order
Arrange these steps of dealing with plaster waste in order.
- Wash tools into a settling bucket, never the sink
- Mix and use only the plaster needed
- Let the sediment settle and pour off the clear water
- Send the set sediment to solid waste
- Let surplus set in the container rather than washing it out
Hints
- The sequence begins before any plaster is mixed.
- Sediment goes to solid waste at the end.
Show the answer
- Mix and use only the plaster needed
- Let surplus set in the container rather than washing it out
- Wash tools into a settling bucket, never the sink
- Let the sediment settle and pour off the clear water
- Send the set sediment to solid waste
Why
The first step is the one that removes most of the problem: plaster waste is mostly over-mixing, and estimating the quantity properly is both the cheapest control and the one nobody thinks of as a control at all.
