Look closely at any part of the system that could injure or harm people on the farm, especially children. Check silo ladders, both external and internal, edge protection, and safe procedures for fumigation, dislodging bridged grain, and rescuing somebody trapped inside. Assess the risk Check whether identified hazards present risk of serious injury, and consider ways risks can be minimised. Don't smoke near silos, and avoid causing sparks from metal friction or electric switches. Carbon dioxide in a silo can displace oxygen and cause suffocation.
High temperatures can cause heat stress for people inside a silo.
Do the job from outside if possible. Wear respiratory equipment when appropriate. Safe fumigation Ventilate fumigated silos before entering. Always follow the manufacturer's recommended safe ventilation period. Open phosphine containers in the open air, not in the shed or silo.
