with additional space(s) of sufficient volume
such that combined volume of all spaces
meet criteria for unconfined space. Size each
opening for minimum free area of 1 square
inch per 1,000 BTU per hour input of all
equipment in spaces, but not less than 100
square inches.
6. Louvers and Grilles of Ventilation Ducts
a. All outside openings should be screened and
louvered. Screens used should not be smaller
than 1/4 inch mesh. Louvers will prevent the
entrance of rain and snow.
b. Free area requirements need to consider the
blocking effect of louvers, grilles, or screens
protecting the openings. If the free area of the
louver or grille is not known, assume wood
louvers have 20-25 percent free area and metal
louvers and grilles have 60-75 percent free area.
c. Louvers and grilles must be fixed in the open
position, or interlocked with the equipment to
open automatically during equipment operation.
