hello guys, I'm in charge of creating our company's cleaning system. one of the procedures required is the procedure on mixing cleaning chemicals. I would like to seek your assistance on the following:
1. do i also need to declare in the procedure the storage and shelf life of each mixed cleaning chemical?
2. do i also need to declare the tools i use to mix the chemicals? (i only use beaker to measure the quantity of the chemical per liter of water and use a carboy as container)
3. or do i just declare how the chemicals are mixed? (ex: 4 ml of quarternary per 1 liter of distilled/filtered water)
thank you guys.
