Zone 1&2  for use in hazardous industrial areas


Owners of off-highway machines have a duty to ensure that their operators are provided with clear indications that they are using the machine within the safe operating limits prescribed by the manufacturer. UK Courts have recently imposed fines and costs of over £40,000 for a single breach of Section 2(1) of the Health and Safety at Work Act where an overturned mower resulted in death of the operator.
