The poster went up in every sluice in February. It showed a scoop, a pan and a tick. In June, an audit of forty containers found that 38 percent had been dosed outside the stated range, nine had no gel at all, and one had been dosed with a laundry detergent scoop that happened to be the same colour. The poster was still on the wall, unmarked and unread.
Dosing is a psychomotor skill with a documentation requirement attached, and neither part transfers through paper. What transfers is a two-minute observed competency, repeated until the person can do it without referring to anything.
Six things, in this order, because the order matters when you are teaching it:
In homes that have run this competency, the single best predictor of overall dosing accuracy was not how well staff dosed. It was whether they had been trained on what to do when a container goes over. Staff who have never been shown a spill procedure handle a leaking pan by adding more powder and hoping, which turns a 300 ml spill into a 300 ml spill plus a slippery gel patch and a blocked sluice drain.
The correct sequence is short enough to teach in ninety seconds: contain with absorbent granules or paper roll, do not add water, scoop the solids with a stiff card into a bag, clean the surface with a chlorine-based disinfectant at the concentration the site uses, and record it. The instinct to dilute with water is the one that spreads contamination across the floor and into the grout.
A dosing log with four fields per line is enough: time, container, grams, initials. Add a weekly stock reconciliation — kilos in, doses logged, kilos remaining — and the log becomes a control rather than a ritual. A variance over 12 percent is a signal, not a disciplinary matter; it usually means the count is wrong, a scoop has gone missing, or a new member of staff has not been signed off.
Keep the signed competency sheets with the log. An inspector asking how the site knows that dose is being applied correctly is asking for evidence of training and evidence of monitoring. One without the other is an assertion.
A care group with eleven homes trained 22 “champions” at a central session and sent them back to cascade the training locally. By the third home in the chain, the dose table had become “one scoop for a normal pan, two for a big one”, with no definition of big. Two homes ended up dosing at 60 percent of the intended rate for three months, and the resulting leaks were attributed to a change of supplier.
The fix was a one-page card with the actual grams and volumes, laminated, fixed inside the sluice cupboard door, plus a requirement that every carer demonstrate the dose to a senior before being signed off. The card is not the training. It is the reference that keeps the training honest when the champion leaves.
An agency carer arriving at 19:00 cannot absorb a twenty-minute induction. What works is a single sheet — where the powder is, which scoop, how many grams for which container, where the log is, who to ask — handed over with the keys, plus a named person on shift who is responsible for checking the first three containers. That is fifteen minutes of someone’s time on the first shift, and it prevents the pattern where agency-heavy nights quietly under-dose for a fortnight.
The measure of whether any of this worked is not the training file. It is the monthly variance and the number of leaking containers reported. Both are visible, both are cheap to collect, and both will tell you in six weeks whether the two-minute competency was real or just another poster. The staff competency checklist is the version to laminate and keep inside the sluice cupboard.
