Ladder Technologies Heat Sensor LabelLadder Technologies heat sensor labels indicate when a ladder needs to be taken out of service for testing due to exposure to excessive heat. Labels are laminated to resist changing color incorrectly due to exposure to elements, smudging and fading.
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. If you have noticed any expired labels, conduct/schedule testing first per NFPA-1932 (Current Edition) and the expired labels must be replaced. New heat sensors are dated out for 5 years.
Place 2 heat sensor labels below the 2nd rung from the top of each inside rail section (1 on the right inside rail - 1 on the left inside rail). Place the other 2 heat sensor labels, including one instruction label at the approximate middle point of each inside rail section (1 on the right inside rail - 1 on the left inside rail with instruction label)
