Full Description

Codes and standards published by NFPA are displayed as read-only under license from NFPA solely for use within this system. NFPA material may not be downloaded, printed, reproduced, or transferred.

Referencethe 2022 edition of 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.

NFPA 269 topics and criteria include:

Summary of test methodsTest apparatusHazards and safety precautionsMaterial test specimens and conditioningEquipment and temperature controller calibrationGeneral procedures and test preparationsCalculations, analysis, and reportingExpert commentary, references, and explanatory materials

Help reduce toxic smoke hazards by following the processes outlined in NFPA 269, Standard Test Method for Developing Toxic Potency Data for Use in Fire Hazard Modeling, 2022 edition.

This important fire and life safety standard offers the most current and reliable criteria for testing materials for toxic potency and data collection for fire hazard modeling. The standard also may assist in the research and development of materials and products. Originally derived from work completed by the National Institute of Standards and Technology (NIST), the changes to the 2022 edition include updated annex material.

NFPA® is your source for the resources you and your team need to help improve fire safety and perform your work to a higher standard.
