Where an installation was in the upper tier – that is, an installation where there was a large quantity of hazardous material – the manufacturer had to provide the HSE with a Safety Case.

Similarly, while the old Regulations referred to ‘installations’, in the new Regulations, the word ‘establishment’ is more usually employed. Regulation 2 provides:
