Flowing grain behaves like a fluid and buries a person in seconds — at waist depth escape is already impossible unaided, and there is no way to swim or climb out. Bridged grain forms a crust with a void underneath that collapses without warning under a person's weight. Both hazards look completely safe from the top of the bin, which is exactly why entries are made casually.
The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.
Flowing grain behaves like a fluid and buries a person in seconds — at waist depth escape is already impossible unaided, and there is no way to swim or climb out. Bridged grain forms a crust with a void underneath that collapses without warning under a person's weight. Both hazards look completely safe from the top of the bin, which is exactly why entries are made casually.
Entries happen alone, without lockout of the unloading equipment, without a harness and without an observer — usually to clear a blockage, under time pressure, on a job everyone has done before. Fatalities in grain bins routinely include the rescuer, because the instinct is to climb in after the person and the second entrant is engulfed in the same collapse.
Quarterly programme verification, every entry permitted individually and never improvised. The non-negotiables — all equipment locked out, harness and lifeline rigged, an observer outside, never walk down bridged grain — are the training content, not the paperwork.
This procedure — and every other PM for your industry — is already built into ChatterFix. Pick your industry and it lands on the right equipment, on the right interval, in about three minutes.
