Safety risk assessment 14: system maintenance was not carried out as required.

A property company is responsible for the operation and management of an office building in Financial Street. The security system of the office building has exceeded the warranty period stipulated in the original project contract. Due to poor internal management of the property management company, no professionals have participated in the maintenance in the past three months. System equipment technology is obsolete, frequent failures, some image information is fuzzy, and even image information is lost many times. In view of the concentrated complaints from the owners, frequent turnover of operators and lack of professional skills in the property management company, the property management company entrusted B security engineering company to carry out system maintenance. After in-depth analysis of the overall operation of the system, the responsible persons of both parties signed a maintenance agreement, formulated a maintenance plan, and appointed engineer Xiao Liu to be responsible for the maintenance of the office building security system.

1 Company and Company B repaired the faults of the system, such as camera displacement, lens occlusion and hard disk damage, and ensured the normal operation of the system.

2. Only Xiao Liu was present when maintaining the recording equipment of the security technology prevention system;

3. Xiao Liu found a fault during the routine inspection of the system and judged that it was necessary to cut off the power supply for maintenance. In order to catch up with the time, he did not communicate with the person in charge of the property, and directly cut off power for maintenance;

4. After each maintenance work, Xiao Liu only made a simple record and did not take the initiative to ask the owner's supervisor to sign for confirmation. ?

Question1:What are the improper practices of Xiao Liu, an engineer of Company B, in carrying out maintenance work?

Key point: Note: According to the maintenance method mentioned in the second question below, find out the inaccuracies expressed in the title. Reference: From the situation described in this topic, due to the poor management of the property management company, the security system of office building A was seriously damaged, which affected the normal office order of the office building and caused great economic losses. This actually reflects some chaos and irregularities in the security industry. As we all know, the maintenance, use, repair and maintenance of the building security system should be undertaken by professional security companies or security companies. However, in practice, some property companies have pieced together some equipment and started to build security systems regardless of their lack of security qualifications and professional security personnel. Although they benefit in a short time, various problems will arise over time. Although these problems can be found and recognized now, they cannot be completely solved in a short time, because there are no authoritative laws and regulations to regulate such matters at present. Then, judging from the behavior of company B involved in this problem, there is something wrong. After accepting the entrustment of the property management company, although they have carried out preliminary work such as making a thorough investigation, signing an agreement and repairing damaged equipment. They also sent engineer Xiao Liu to be responsible for the maintenance of the security system of the office building in time, but the company did not put forward clear and strict requirements for the specific workflow, nor did it send inspectors to the site for inspection during the process; Look at the behavior of engineer Xiao Liu. As a front-line engineer, he shoulders the overall responsibility of the whole construction site, and should also be familiar with and strictly implement the relevant rules and regulations. However, only one person was present when Xiao Liu was maintaining and repairing the recording equipment of the security technology prevention system. Failure was found during routine inspection of the system, and it was judged that the power supply needed to be cut off for maintenance. In order to catch up with the time, he directly cut off the power supply for maintenance without communicating with the property manager. After each maintenance work, Xiao Liu only made a simple record and did not take the initiative to ask the owner to sign for confirmation. In fact, Xiao Liu has great security risks in doing so, and it is easy to cause major security accidents. Then, let's take a look at the specific regulations and requirements for security engineering maintenance and maintenance personnel! There are mainly the following seven items.

(Reference to the first question):

(1) Maintenance personnel must protect the site environment of relevant units.

(2) The maintenance of the whole system shall be carried out at least 2-4 times a year, and a report shall be written, the content of which shall be no less than the items listed in the Maintenance Requirements of Safety Technical Prevention System, or in accordance with the contract requirements.

(3) When the maintenance unit checks the system, it shall report the abnormal situation to the parties in time.

(4) The maintenance unit shall obtain the written consent of the parties before the power outage.

(5) Every maintenance work must be recorded in writing, and the maintenance work should be signed by the responsible person and the person in charge of the relevant unit for confirmation and archiving.

(6) Maintenance records shall be made in duplicate, and each party and the daily maintenance unit shall keep 1 copy until the system fails.

(7) Maintenance records shall be filled in with pens or signature pens, and pencils and ballpoint pens shall not be used.

Question 2. What maintenance methods should maintenance personnel master in order to do maintenance work well? ?
