Answer :
According to British Standards, when gas pipes are installed horizontally, they must be supported at certain intervals to ensure safety and structural integrity.
Horizontal gas pipes should be supported at least every 2 metres. This ensures the pipes do not sag or are subjected to unnecessary stress, which can lead to leaks or failures over time.
Thus, the correct option is d) Every 2 metres.
Supporting gas pipes properly is crucial because gas pipes are part of a safety-critical system. Incorrect support can lead to increased maintenance needs or, in worst-case scenarios, safety hazards. Proper support distributes the weight of the pipe and its contents evenly and prevents mechanical strain on joints and fittings.
In summary, for safe installation in accordance with British Standards, support horizontal gas pipes every 2 metres.
