- other pressure vessels containing:

- harmful fluids (toxic or corrosive)

- fluids with flash point below 100°C

- fluids with temperature above 220°C

- fluids with pressure above 40 bar

- compressed gases where

pd × V ≥1500 bar ltr

- boilers and hot water generators, including equipment, valves and fittings

- thermal-oil heaters, including equipment, valves and fittings

- oil or gas burners and oil or gas firing equipment.

pd = design pressure

V = volume.
