As the majority of silos are not pressure rated vessels they can rupture at pressures as low as 1 or 2 psi. Without adequate safety systems in place sites risk fatal injury to staff, damage to equipment, product loss and environmental pollution - not to mention hefty Health & Safety fines. Therefore silo protection is essential for avoiding the risks of over-pressurisation and overfilling. Guidelines from the Mineral Product Association (MPA), the HSE and DEFRA all make clear the importance of a reliable, testable safety system that is kept in optimum condition through regular servicing.
