Victor Rivera Hernández, SecretaryExposure of Blades, 29 CFR 1910.212(a)(5), specifies that all fans within 7 feet of the floor or working level must be guarded. The guard must not have openings greater than one-half inch in width. The use of concentric rings with spacing between them not exceeding a one-half inch are acceptable, provided that sufficient radial spokes and firm mountings are used to make the guard rigid enough to prevent it from being pushed into the fan blade during normal use. The standard would apply to fan blades of cooling fans for motors and pumps, as well as cooling fans and turbine blades for Commercial Air Handling Units, which are 7 feet off the floor or working level.
