Take note
Pre-marking serves as a visual aid. The bucket used to measure water is marked for 1, 2, and 3 gallons. These were common volumes used to mix pesticides at a greenhouse.
Idea...
A manager thought of this idea when he had difficulty explaining gallon measurements to a handler who only knew the metric system. Instructing the handler to fill to a specific mark improved communications and reduced measurement error.
Setup & use
- Clearly mark desired volume using permanent black marking pens
- Label each container that will be used only for specific agricultural products. For example, one container will be only for pesticides or only for herbicides use.
- Decontaminate measuring containers after each use.
- Check and replace markings before they wear off.
Alert
For accurate measure of dry products, weigh each batch separately. Do not measure additional batches by filling a container up to a mark. Remember, the same volume may have a different weight depending on the size of the dry particles.
Supplies
- Measuring pitchers (clear)
- Black permanent marker
Tips
- Use a 2-gallon measuring container for oils to minimize spills and lifting weight.
- Remember to mix pesticides in the proper order.
- Use a different measuring container for each product to prevent cross contamination.
- Provide handlers training on the United States Standard Units for liquids and weights.
