Defect
In fire apparatus, the engine block heater (cold-weather starting aid) is equipped with insulating caps on its terminals that have insufficient heat resistance. Repeated extended energization over a long period causes the caps to degrade and lose their insulating properties. If road salt or other de-icing agents subsequently penetrate the terminal area, corrosion increases contact resistance, causing the terminals to overheat and resulting in a broken wire or burn damage. In the worst case, this can lead to a vehicle fire.
Corrective action
Replace the heater and power cord on all vehicles with the corrected parts.

状況
消防車両に装備されているエンジンブロックヒータ（冷寒時始動性向上装置）において、端子部の絶縁用キャップの耐熱性が不足しているため、長期間にわたり長時間通電を繰り返すと当該キャップが劣化し、絶縁性能が低下することがある。そのため、使用過程において、融雪剤等が端子部に浸入すると、腐食により接触抵抗が増加して、端子部が発熱し、断線または焼損することがあり、最悪の場合、火災に至るおそれがある。
改善措置
全車両、当該ヒータおよび電源コードを対策品と交換する。
