1. Check and maintain all distribution boxes and switch boxes on the construction site once a month. Maintenance and repair personnel must be professional electricians. When working, you must wear insulating articles and use electrical insulating tools.

2. When inspecting and repairing the distribution box and switch box, the corresponding power switch at the next higher level must be switched off, and a power-off sign should be hung. It is forbidden to work with electricity.

3, the disk in the distribution box should indicate the name and purpose of each circuit, and make a shunt mark.

4, the total distribution box door should be equipped with a lock, distribution box and switch box should appoint someone who's in charge. When the construction site stops working for more than 1 hour, the power switch box should be locked.

5, all kinds of electrical boxes are not allowed to put any sundry, and should be kept clean. No other temporary electrical equipment shall be hung in the box.

6, all kinds of electrical box fuse melt replacement, it is forbidden to use the melt does not conform to the specifications instead.

Fire prevention measures for electricity consumption in construction site

1, reasonably and correctly select the conductor section, theoretically put an end to the overload use of the line, and carefully select the protection device to protect the line within the specified time when the line is overloaded for a long time.

2. In summer, due to the rising temperature, construction workers are prone to fatigue and mood swings, etc., and safety warnings should be given in time to require all construction workers to rest and maintain vigorous energy.

3. Electric furnaces are strictly prohibited in the construction site. When using iodine tungsten lamp, the distance between lamps and combustible materials should be more than 30cm, and lamps with power exceeding 100w are not allowed indoors. Bedside lamps are strictly prohibited.

4. When using electric welding machine, it is necessary to implement the system of using fire certificate, and have special supervision to check the carrying and intact conditions of construction equipment, safety equipment and labor protection articles.

5. Lightning protection, grounding and anti-static measures should be taken for large equipment and electrical equipment that may generate static electricity on the construction site, so as to avoid fire caused by lightning electrostatic sparks.
