All work must comply with applicable regulations, standards and manufacturer requirements.


Particular care must be taken when working at heights, in roof spaces, ceiling spaces and other restricted access areas. Additional consideration must be given to confined working conditions, electrical hazards, moving parts, water systems, wet surfaces, manual handling risks and weather conditions.


Do not proceed if safe access, weather conditions, required clearances, confined space risks or appropriate safety controls cannot be achieved and maintained.


Safety takes priority over diagnosis, repairs, installation schedules and customer expectations. If the task cannot be completed safely, it must not proceed until the risks have been adequately controlled.
