1, according to shift duty engineer memories, 9 August 28, daily patrol, found in hot water tank of basement, after checking of water treatment equipment automatically find fault caused by water system. In the circumstances, failing to repair tank opened in automatic filling switching around will for artificial hydrating. In the morning after 11 when the water tank, inspect the basement level is 9 30CM has risen from normal level, but still 50CM,. And then again this afternoon, he found the basement has been touring 1.4 M deep water, soak in water, all the equipment running (for the memory stop, the hotel will please verify related technical personnel.2, the hotel received engineering manager on duty engineer reports to get around 1, after the hotel, and immediately notify hotel project contracting Shanghai construction and decoration Co., LTD, and emergency handling the hotel's request of architectural decoration Co., LTD with related equipment to send, and emergency assistance drainage pumping water pump to brother borrowed hotel. The accident happened on Saturday, when most engineering staff and equipment suppliers of technical staff rest at home. But part of the hotel, should rest at home after being notified of employees to work in hotel has arrived. Thus, support staff and related drainage device to arrive, drainage works, large pump operation, all four basic clear about chose basement water.3, glanf pump device, ambitious air-conditioner, hua sheng electronic KaiGuanChang, guangzhou pump factory technical personnel should request to hotels, restaurants for damage successively for repair or equipment repair work, and to assist in the maintenance of equipment manufacturer hotel active connections. The 22:50, damaged and pump all night, and remove to repair. KaiGuanChang hua sheng electronic engineer, to give rest to maintenance fittings factory, 29 to damage at 2 sets of distribution box on emergency repair, Pump repair employees to work overtime, 29 overnight at 3:30 completed need use 4 pump maintenance, installation and debugging of complete and.4, in grundfos engineer's help, 29, at 12:30 locker rooms and hot water. Employees recovery5 and 8 August 31 points, and the rest of the LiuTai pump repair, and installation. That night, on a high frequency pump installation, On September 1st at 9:30 points finish debugging operation. 2 at the high frequency converter is damaged, low in the factory maintenance of converter for all water soak in water, already cannot repair, waiting for the delivery.Based on the investigation and analysis of the accident, I think there are as follows:A scheduling department, the irrational, weekend arrangements that less attendant, repair work is met, operators to previously dealt with the fault equipment observation,Second, the hotel is a daily patrol system for the implementation of the regulations, also revealing going-over. But on the patrol duty engineer and staff and the quality of touring, lack of necessary monitoring method, daily patrol the quality and the effect to evaluate,Third, since restaurant area is too small, the nervous when necessary, design of electric equipment, water pump will be placed in the basement. However for heavy equipment running status monitoring shut by technical means, less, lack of automatic alarm system,In view of the above analysis, the hotel will take the following measures:A total package, tissue engineering, design, construction, equipment manufacturer to the hotel, the overall inspection equipment, eliminate unsafe,Second, according to the safety equipment, perfect solution, strengthening technical measures,Third, the reasonable adjustment, balance scheduling staff collocating, avoid weekends and holidays on-the-job personnel less occurs,Four, reiterated department division, strengthen the post responsibility consciousness; to implement the responsibility,Five, perfect equipment failure process, make more scientific and reasonable treatment,Six lines, even entire store staff on engineering education, improve the production safety of the employees work safety awareness and responsibility,In this accident, seven, to all the weight off equipment department, improve the comprehensive safety assessment safety measures and troubleshooting plan,The accident caused a great hotel, for the economic losses, the damage of equipment only reached 16 million direct losses caused by accident, the indirect loss is invaluable for the engineering manager, responsible for an unshirkable responsibility, therefore, request the hotel to sanction.
