Specifications : Thermal Lining System The Thermal Lining System (TLS) and appurtenances shall be free from asbestos or other harmful ingredients, and shall not produce toxic bi-products in the course of the intended use. Material Safety Data Sheets (MSDS) relating to the proposed TLS must be submitted with the proposals. The TLS must be capable of protecting the structural components of the Burn Building from interior temperatures of 2000 degrees Fahrenheit, while not allowing temperatures exceeding 300 to 350 degrees Fahrenheit to be transmitted to the structure in accordance with NFPA 1403 standards only. The TLS must withstand the constant effects of the products of combustion during normal training exercises and their residual effects after training has been completed. The TLS must withstand the constant thermal shock created during fire extinguishment training evolutions using water from water mains, without spalling, cracking, splintering, or any other degradation. This includes, but is not limited to: The TLS must have the appropriate properties to allow for expansion created by rapid heating and cooling. The TLS properties must not break down under repeated use. The TLS must withstand the effects of thermally pressurized steam, created when using mechanically pressurized water for fire extinguishment. Surfaces shall allow for minimum water and steam penetration into the TLS and protect the structure from the same potentially harmful effects. The TLS must have the appropriate structural properties to allow for attachment with the proposed anchoring system. The system should allow for the fact that almost all cementitious materials will absorb water through direct water application or through condensation caused by large fluctuations in temperature, such as those commonly experienced during winter months. Once this absorbed water is abruptly heated during a fire, it will convert to pressurized steam which could act to degrade the lining material. The TLS system shall be designed to expel such water and vapor that could penetrate the system. The TLS must be functional in all seasons of the year. The material must withstand physical abuse from fire fighters' protective clothing, self-contained breathing apparatus, and small hand tools. The TLS must withstand the effects of any oxygen deficient atmosphere. The TLS must be functional year-round, withstanding the effects of seasonal weather considerations without restrictions. The TLS must allow for the use of surface and subsurface mounted thermal tubes and their penetration through the TLS at sidewalls and ceiling.
