Depending on how wet the grain was going in, there is always a chance for crusting near the top of the bin. Do not attempt to walk across a bridge of corn within the bin, it could collapse causing full engulfment. Also watch out for vertical wall crusts. Removing the grain from the wall can cause an avalanche-like affect leading to engulfment as well.
We have a busy season coming up folks, let’s not start off on the wrong foot!
