OSHA Designated areas

According to the most recent update to OSHA 1910.29, regular and routine maintenance workers can be protected using demarcated, designated areas when they are fifteen feet or more from the roof edge. In rare instances, when the work is infrequent and temporary, a designated area can also protect a worker who is six or more feet from the roof edge. To meet the demand created by this updated language in the regulation, we have designed a purpose-built Warning Line solution to create OSHA designated areas on worksites.

Designated areas according to osha 1910.29(d)

The employer must ensure each warning line:

  • Has a minimum breaking strength of 200 pounds
  • Is installed so its lowest point, including sag, is not less than 34 inches and not more than 39 inches above the walking-working surface
  • Is supported in such a manner that pulling on one section of the line will not result in slack being taken up in adjacent section causing the line to fall below the limits specified
  • Is clearly visible from a distance of 25 feet away, and anywhere within the designated area
  • Is erected as close to the work area as the task permits
  • Is erected not less than 6 feet from the roof edge for work that is both temporary and infrequent, or not less than 15 feet for other work.
