Dear Mr. Weinstein:

This is in response to your letter requesting clarification of the Standard 1926.105 on Safety Nets.

The OSHA Standard 1926.105(a) requires that nets be used "where use of ladders..., safety lines or safety belts is impractical." The language of the Standard seems to give preference to all other methods of safe guarding leaving safety nets as a last resort because no other safeguard can be used.

Please note that the OSHA Standard 1926.105 specifies 25 feet or less. The 30 foot figure comes from [1926.760] flooring requirements for steel erection which was changed from 25 to 30 feet on June 30, 1974.
