Industrial Hazards - Construction - Truss

For TRUSS CONSTRUCTION signs you've come to the right place: ComplianceSigns.com

Truss systems help the construction industry, but can also pose a serious threat to firefighters during an emergency. The National Institute for Occupational Safety and Health (NIOSH) recommends that building owners post construction information - including presence of roof and floor trusses - outside all buildings. Some state and local fire marshals require specific identification of buildings with truss construction. (More information below and on local pages.)

Here you'll find a big selection of truss identification signs and labels, as well as truss signs designed to meet requirements of specific states and cities. All our truss signs are made in the USA of industrial-grade materials. Please check the product description to ensure you select an appropriate truss sign or truss label for your location.

Truss Construction and Fire Safety:
The Wood Truss Council reports that wooden trusses are used in roof systems in more than 60% of all buildings in the United States, and truss and related engineered wooden floor systems are also becoming more common. Under fire conditions, these truss systems can weaken and fail, leading to collapse of roofs, floors and the entire structure. Truss systems are usually hidden, and fires within truss systems may go unnoticed for long periods of time, resulting in loss of integrity.

Fifteen separate incidents investigated by NIOSH identified at least 20 fatalities and 12 injuries from 1998-2003 during fire-fighting operations in buildings containing truss systems. Roof and floor truss system collapses in buildings that are on fire cannot be predicted and may occur without warning.
