Structural Fire Protection
Fire protection products used in the construction of buildings, ships and offshore facilities are required to conform with the certification listings or approvals. The field installation will comply with code requirements if it is configured within the maximum and minimum tolerances in the listings and approvals. For example, if a drywall assembly has a listing of a 2 hour fire-resistance rating, and all the provisions of the listing were kept in the field, including materials, spacing, workmanship, etc., the 2 hour wall required by the building's designer is likely to withstand a 2 hour fire.

The disclosure of the inadequacy of fire testing employed in the circuit integrity product led to widespread and costly remedial work for licensees of the Nuclear Regulatory Commission.

Famous quotes containing the words structural, fire and/or protection:
“The reader uses his eyes as well as or instead of his ears and is in every way encouraged to take a more abstract view of the language he sees. The written or printed sentence lends itself to structural analysis as the spoken does not because the reader’s eye can play back and forth over the words, giving him time to divide the sentence into visually appreciated parts and to reflect on the grammatical function.”
—J. David Bolter (b. 1951)
“Although sleep pressed upon my closing eyelids, and the moon, on her horses, blushed in the middle of the sky, nevertheless I could not leave off watching your play; there was too much fire in your two voices.”
—Propertius Sextus (c. 50–16 B.C.)
“Freedom of religion, freedom of the press, and freedom of person under the protection of habeas corpus, and trial by juries impartially selected. These principles form the bright constellation which has gone before us, and guided our steps through an age of revolution and reformation.”
—Thomas Jefferson (1743–1826)
