Mich. Admin. Code R. 325.2434 - Supply ventilation systems
Rule 34.
(1) A
supply ventilation system shall be provided to ensure a flow of air into the
working environment to replace the volume of air exhausted.
(2) A mechanical air supply system shall be
provided if its absence will result in building negative pressures sufficient
to cause back-drafting of vents from fuel-fired equipment or ineffective
control.
(3) Mechanical air supply
volumes shall be heated to maintain a minimum air temperature of 65 degrees
Fahrenheit measured at the point of air discharge to the space. Exceptions to
this requirement are refrigerated storage rooms, special process rooms, and
similar locations where lower air temperatures are essential to the
preservation of the product or service, or, if in the opinion of the director,
a lower air temperature will not be harmful to the health of the persons
affected.
