The spontaneous combustion of the battery car in the corridor leads to the blackening of the corridor wall. What is the responsibility of the property and how much should the property of the corridor wall compensate? The property company has no responsibility. China's "Fire Protection Law" stipulates that battery cars and other items should not be parked in the corridor, and the corridor should be kept clean and smooth. Moreover, the spontaneous combustion of the battery car is a quality problem or disrepair of the battery car, and the manufacturer or the owner should be responsible. As long as the property company does its duty of patrolling, it is impossible to watch the owner's belongings for 24 hours, and the property company has no obligation to keep the owner's belongings.
