We are designing a process plant under EN 13480, one of the fluid is Hydrogen Cyanide and our HSE team has deemed it as a "Category M fluid". As far as I am aware, Category M is not defined as such under EN 13480 (or PED).
Am I missing anything in EN13480 that lays down rules for designing a Lethal Fluid piping system?
if not, I am planning to use B31.3 Chapter VIII as a "guide" (although our material selection shows a non-metallic for this fluid, which is explicitly prohibited in Chapter VIII) but I am not sure how a NoBo will take this.
