They are physically up to it - this is less of an issue when using a smaller mixer, but
feeding larger mixers over a long period is a physically demanding task.
They don't mind doing a repetitive task over and over, and understand the importance
of, and take on the responsibility for, getting it right every time. Your worst-case scen-
ario is someone who isn't really bothered whether they get it right.
They are well organized, and have a natural tendency towards keeping things clean and
tidy - the work area, the mixer itself, and the buckets and tubs.
They can count (it sounds basic, but you'd be surprised!) and remember how many
buckets they've already put in.
They don't mind being on the sharp end when it comes to handling the lime binder, and
getting splashed with water at the same time (not a great combination).
They have a responsible attitude to health and safety and PPE.
They don't go to pieces under pressure, and have the confidence and communication
skills to get other team members to keep them supplied with raw materials.
If you haven't found a person you can rely on to consistently do the mixing properly, then
it's best to do it yourself, as it must be done correctly.
