Hello food safety hivemind.
I am updating cleaning directions/checklists for our production areas.
One of the things that has prompted these updates is the fact that there is great inconsistency in the way that operators follow dilution instructions for the various cleaning chemicals, etc.
For example - the manufacturer instructions directions for use instruct a dilution of one part chemical solution to 100 parts water.
The operators in area 'A' are used to making simple mathematical calculations and so fill their 20 litre bucket to the halfway mark and measure out 100ml of cleaning solution.
Operators in area 'B' are not used to making calculations - they half fill the same bucket but put in 'a few glugs' of cleaning solution.
Obviously we want to standardise things and get everybody using cleaning chemicals as directed - the obvious option for us to correct these bad practices is to issue measuring jugs and train people up in making the proper calculations.
However, a manager has challenged this by asking me to find an easier, more practical solution that would mean operators wouldn't have to make calculation (and therefore errors in orders of magnitude, etc.)
The only method I can think of to avoid calculations (without installing dosing equipment) is to provide a 'ready reckoner' or something similar, where they can just retrieve the required info from a table.
Seems like this would be just as problematic as the first option - does anybody have any other suggestions?
