Fire Damper Inspection
The Joint Commission, State Fire Marshals and Other Authorities Having Jurisdiction (AHJ's), require Fire and Smoke Dampers to be tested at specified intervals.
In regions which enforce NFPA Standards (e.g., North America), fire dampers and combination fire/smoke dampers require inspection and testing one year after installation, and then every 4 years; except in hospitals, where the frequency shall be every 6 years. Documentation indicating the location of the damper, date of inspection, name of inspector and deficiencies discovered is also required.
Repairs should begin without delay if a damper is found inoperable.

Famous quotes containing the words fire, damper and/or inspection:
“Prosecutors insist they are mounting a “thorough investigation,” which sometimes means thorough and sometimes, historically, has meant long enough to let the fire burn down in an incendiary case. A thorough investigation is fine; an interminable one is disgraceful.”
—Anna Quindlen (b. 1952)
“The shy man does have some slight revenge upon society for the torture it inflicts upon him. He is able, to a certain extent, to communicate his misery. He frightens other people as much as they frighten him. He acts like a damper upon the whole room, and the most jovial spirits become, in his presence, depressed and nervous.”
—Jerome K. Jerome (1859–1927)
“Thus the orb he roamed
With narrow search, and with inspection deep
Considered every creature, which of all
Most opportune might serve his wiles, and found
The serpent subtlest beast of all the field.”
—John Milton (1608–1674)
