At this time of year, many polyethylene tanks are being used across the vegetable industry for storage and transportation of water, fertilizer, and pesticides. However, each poly tank has a limited lifespan, and the potential for failure once it is beyond that lifespan.
Michigan State University Extension has posted a helpful article, Poly tank inspection techniques — Maintenance of polyethylene tanks is critical for safe use. It is well worth a read, when you consider some of the consequences of a tank failure. You will also find out how hitting your poly tank with a baseball bat can be a good thing. But it should be empty first.
Another excellent resource on poly tanks is the Purdue Extension Bulletin, Poly Tanks for Farms and Businesses … Preventing Catastrophic Failures (pdf). This bulletin includes photos of some of the aforementioned catastrophic failures.
After looking at those photos, and inspecting and maintaining (or replacing) your tanks, you might want to print off the OMAFRA Factsheet Ways to Avoid Pesticide Spills. It includes information on prevention, what to do if you have a spill, the contact information you will need in case of such an emergency as well as a place to list your local emergency contact numbers.
Please do all you can to stay safe this season.
