HEAT SENSOR LABELS:
These are visual warning labels furnished on all aluminum and fiberglass ladders since January,
turn black if any
heat is ever
present that is greater than approximately 300 degrees F. The 300 degree F temperature is used
because once aluminum fire ladder materials (6061-T6 alloy) reach this 300 degree F (even if
only for a moment), the ladder material may have lost at least 25% of it's load capacity. This heat
exposure effect is not reversible in the ladder and can continue to accumulate over it's entire life.
NOTE: If any heat sensor label becomes black - remove the ladder from service at once and
have the ladder load tested before the ladder is ever used again. If the ladder passes the load
test - you have had a false alarm - replace the heat sensors and return the ladder to service.
Replacement heat sensor labels are only available for ladders that have passed the load test. If
the ladder does not pass the test, we will not supply you with new labels. Call the factory for
REMEMBER: Heat sensor labels that look OK do not make the ladder safe to use.
N.F.P.A. now requires 4 heat sensors and one instruction label per ladder section. Each heat
sensor has an expiration date printed on them. Any expired labels must be replaced. Place 2 heat
sensor labels below the 2nd rung from the top of each section (1 on the right rail - 1 on the left
side) inside the rail. Place the other 2 heat sensor labels (one with instruction label) below the
middle of the section inside the rail. (1 on the right
