Preventing Accidents Involving Air Conditioners
Product Safety Technology Center
Product accidents reported to the Product Safety Technology Center at NITE include 467 cases*1 involving air conditioners in the six years from fiscal 2005 to fiscal 2010. Classifying these cases by damage, they include five cases with casualties, three cases with severe injuries, 26 cases with minor injuries, and 99 cases where a room or wider area caught fire*2.
Analysis of conditions at accidents involving air conditioners*3 has revealed that the following types of accident occur most frequently.
Fire caused by poor electrical contact in the connecting cable*4 or extension lead, or faulty connection between the power cord and plug
Smoke or fire due to an air conditioner cleaner or the like being attached to the power connector, leading to tracking because of condensation
Smoke or fire due to deterioration in the insulation of an electrical part or electrical leakage after prolonged use of the product
Some of the accidents involving air conditioners were caused by faulty work by the builder as indicated in [1] above. Accidents involving air conditioners have increased since fiscal 2008, and they tend to increase especially in June and July. The power saving measures introduced after the Great Earthquake to deal with the power shortages are expected to increase the need for cleaning of air conditioners. Therefore, NITE has decided to promote consumer awareness on this issue to prevent accidents involving air conditioners.
Number of accidents excluding overlapping cases or non-applicable cases at May 31, 2011
Fire in part of a building, such as a pillar or a floor
Accidents occurring in the five years from fiscal 2005 to fiscal 2009, excluding cases caused by problems only involving design, manufacture or indication (Cause Category A) and cases under investigation (Cause Category H)
