OMAHA, Neb. (AP) — Working in grain bins can be deadly, so insurers want to remind farmers of the dangers.

Nationwide insurance is helping sponsor a campaign to educate farmers about safety procedures they can use when working in grain bins.

Farmers should wear proper safety gear when they enter grain bins and test the atmosphere for toxic gases.

Brad Liggett with Nationwide says the insurer is also working with other groups to train first responders and provide grain bin rescue tubes to fire departments.

Since 2014, 77 fire departments in 24 states have received the rescue tubes that help protect someone stuck in the grain while responders work to rescue them.
