Confined spaces like silos, tanks, manure pits and other enclosed structures present a hazard to farmers and children.
When in a silo, a person can be drawn under moving grain within seconds, like ‘quick-sand’. To prevent accidents, all ladders should be above child height and fitted with a device to prevent child access. Modern silos are now fitted with safety grids to restrict access.
Other confined spaces such as water tanks and manure pits can also be dangerous. It’s essential to follow proper safety procedures when you work in any confined space.
Water tanks, silos, wells, vats, manure pits, tunnels and other confined spaces can suffocate a person with either fumes or low oxygen levels. Farm workers, children and other people entering these spaces are at risk. People making a rescue attempt can also be in danger. Proper safety procedures are vital, including having a rescue plan and appropriate safety equipment.
