Q7A does not address this because it’s up to the manufacturer to determine what is adequate
protection for their particular processes. Section 4.1 states, “Where the equipment itself, (e.g.,
closed or contained systems) provides adequate protection of the material, such equipment can
be located outdoors.” If it’s a reactor, and it’s completely closed, that’s probably fine. If it’s
equipment that you are opening outside to sample or to introduce materials, you may need some
temporary protection where the system is being opened.
