Many building code provisions attempt to establish minimum requirements for structural strength, entry and exit, lighting, ventilation, fire control and other elements to safeguard occupants of new and existing buildings. Features such as hallway and staircase width, ambient and emergency lighting, door sizes, plumbing fixture heights, fire prevention components, and staircase and balcony railing requirements are just a few design elements that may be addressed by building code provisions.
On a roof, few building code provisions exist to safeguard workers exposed to unprotected edges, skylights, roof hatches and other openings. Because of that void, responsibility for protecting workers from dangers inherent in a building's design with respect to roofing activities rests with the construction trades, including roofing contractors, who must access rooftops to perform work.
As a result, worker safety often balances precariously on the quality of temporary fall-protection equipment; worker understanding, proficiency in setup and operation of such equipment; the equipment's suitability for hazards specific to the building; and full compliance by workers using safety equipment.
In 2005, a group of NRCA members and a member of RCI Inc. began identifying building design elements essential to ensuring worker safety during roof system construction and maintenance activities. Numerous meetings, writing and editorial sessions, and conference calls during the years have resulted in a document that establishes NRCA's recommendations with respect to building design elements intended to safeguard workers on roofs. Titled Building Design Elements for Enhanced Fall Protection for Construction and Maintenance Personnel: An NRCA Perspective, the document can be downloaded for free from NRCA's website, www.nrca.net.
