The Phoenix Fire Department, Phoenix, Ariz., has adopted the Tent Rental Division (TRD) guidelines for tent staking and ballasting. Beginning June 15, 2012, the department will only approve tent or canopy permits and installations if the tent staking or ballasting plan is in accordance with the IFAI Procedural Handbook for the Safe Installation and Maintenance of Tentage and the IFAI Pullout Capacity of Tent Stakes.
The tent or canopy owner or rental company that is responsible for the tent and tent installation must provide the installation instructions, as outlined in the IFAI handbook, at the time of permit application. Documentation on how they will meet the requirements is needed before the permit will be issued. The publications are available at IFAI's bookstore.
