construction and contents of a building such as
furniture, wall coverings, carpeting, drapes, wood, and
paper. Wool carpeting and upholstery produce deadly
hydrogen cyanide gas. Wood produces carbon
monoxide, a primary cause of fire deaths. These
materials ignite at a much lower temperature than ENT.
c. Various tests conducted by combustion toxicologists,
third party certifying agencies, and testing laboratories
conclusively prove:
• PVC Raceways DO NOT generate HCI (Hydrogen
Chloride) in lethal concentrations.
• In an actual large scale fire test, PVC conduit
maintained the integrity of electrical circuits, even in
the case of flashover.
• In a fire situation, PVC conduit will protect the
integrity of conductors significantly longer than steel
conduit.
• PVC is a practical conduit material.
• Metallic conduit systems do not guard against fire
ignition (may promote arcing if not properly
grounded.)
• PVC conduit is superior to metallic conduit in most
applications.
• Since both metallic and nonmetallic raceways are
recognized by NEC, the buyer can decide which
product is best suited to the installation requirement.
• A real concern for life safety in fires must be directed
toward eliminating fire ignition, providing better
control of burnables in the room and priding state-
of-the-art fire protection and sprinkler systems. These
are the goals of many recognized fire authorities.
8. HOW EASY IS ENT TO HANDLE ON THE JOB?
Let’s take a look:
1
/2 inch ENT weighs 11 pounds per 100 feet.
1
/2 inch EMT weighs 29 pounds per 100 feet
(or one bundle).
You can easily carry two coils of ENT (200 feet per coil)
weighing 44 pounds, compared to 4 bundles of EMT
(10 feet long per bundle) weighing 116 pounds.
