NFPA 269 PDF

Reference NFPA 269 for the latest knowledge and procedures for testing products and materials to determine their lethal toxic potency when ignited.

Combustible material and products inevitably produce toxic smoke when on fire. NFPA 269, Standard Test Method for Developing Toxic Potency Data for Use in Fire Hazard Modeling, provides a standard approach to developing data for use in toxic hazard modeling to help protect people from toxic smoke.

The standard is your guide for performing tests to measure the lethal toxic potency of combustion products produced from a material or product ignited resulting from radiant flux exposure. The data collected include the quantification of toxicity of the smoke, which is valuable in determining whether the detected toxicity is associated with the primary toxicants.
