Suppression

Active suppression can prevent a small fire from growing into a big fire. We research the performance of suppression systems so you have the latest knowledge to design and maintain solutions that perform as intended.

To learn about older reports, you can:

• see a list of reports, or search and download from the NFPA Library & Archives catalog;
• contact the library at +1 617 984-7445.

You can also browse NFPA workshop and symposium proceedings on this topic.
