Safety Notice – Important – Read This!

Working in and around bins, silos, and tanks
Entering a bin, silo, tank or other type of storage structure is hazardous. You can suffocate and die from the materials stored inside these structures. There also may be explosive, harmful or poisonous gas or dust in the air. A vac operator and all other personnel assisting should strictly adhere to the procedures outlined in “Bin, Silo, and Tank Entry Procedures” before entering a storage structure. For additional details regarding these procedures, reference OSHA Standards.

When entering grain tanks, bins, and silos, also follow these tips – “Bin Entry Do’s and Don’ts” from the Kansas Grain and Feed Association’s Safety, Health and Environment Committee.

Working with and around your vac
Before using your vac, it is your responsibility to read, understand and follow all of the safety instructions in your operator’s manual. Also make sure that EVERYONE operating or near your vac understands and follows all of the safety instructions in the manual.

Remember, a safety-minded, informed operator is the most important safety aspect of your vac. Accidents can be avoided. Do not risk injury or death — be certain that every operator of your vac is well acquainted with all the safety recommendations and operating instructions in the manual. Read “Vac Safety Guidelines”
