Temporary Electricity Safety Common Sense

Temporary electricity refers to the design, installation, use, maintenance and removal of low-voltage power systems using electric equipment and lighting on the production and construction sites during temporary overhaul or maintenance and engineering construction. The main facilities and materials for temporary power utilization include transformers, power distribution cabinets, distribution boxes, switch boxes, cables, wires, electrical tools, electric tools, lighting fixtures, electrical equipment, etc. Basic management requirements for

temporary power consumption:

temporary power consumption organization design shall be prepared for the construction site with 5

or more temporary power consumption equipment or the total capacity of equipment is 50kW or more. 2.

Temporary electricity consumption organization design must follow the "

preparation, review and approval " procedure, which shall be organized and compiled by electrical engineering technicians and implemented after being reviewed by relevant departments and approved by the technical director of the enterprise with legal personality. 3.

Temporary power consumption project shall be constructed according to the design drawing, and shall be jointly accepted by relevant units before being put into use after being qualified.

Temporary electricity use must establish safety technical files, which shall be established and managed by electrical technicians. Among them, "

electrician installation, inspection, maintenance and demolition work record " can be assigned to be managed by an electrician, which shall be reviewed and approved by the main person in charge or project manager every week, and shall be filed uniformly after the temporary power consumption project is demolished. 5.

Temporary power consumption shall be checked regularly, potential safety hazards shall be handled in time, and rechecked and accepted.

Basic requirements for electricians and electricity users:

Electricians must pass the examination and obtain the special operation certificate before taking up their posts; Other electricity users must undergo safety training and technical disclosure before they can take up their posts.

Installation, inspection, maintenance or removal of temporary electrical equipment and lines must be completed by an electrician and supervised by a special person.

All kinds of electricity users should master the basic knowledge of safe electricity use and the performance of the equipment used, and should meet the following regulations:

Before using electrical equipment, they must wear and equip corresponding labor protection articles according to regulations, and check electrical devices and protection facilities. It is strictly forbidden for equipment to operate with diseases.

Keep and maintain the equipment used, report and solve any problems found in time;

The switch box of temporarily deactivated equipment must disconnect the power isolation switch and close the door and lock it.

When moving electrical equipment, the power supply must be cut off by an electrician and properly handled. Introduction to

Electrical Equipment:

Electrical Equipment Switches shall adopt automatic control electrical appliances such as contactors and relays, and manual two-way transfer switches shall not be used as control electrical appliances.

2. In the switch box of Class I

and Class II

metal shell hand-held electric tools, the rated leakage action current of the leakage protector shall not be greater than 15mA , and the rated leakage action time shall not be greater than 0.1s . 3.

When operating in wet places and on metal frames, Class II

or Class III hand-held power tools powered by safety isolation transformers must be selected. 4.

It is strictly forbidden to use Class I

hand-held electric tools in wet places or on metal frames. 5.

The load line of the water pump must adopt waterproof rubber sheathed copper core flexible cable. Any damage and joints are strictly prohibited, and no external force is allowed.

When cleaning, inspecting and maintaining concrete mixers, steel bar processing machinery, woodworking machinery and other equipment, the switch box must first be switched off and powered off, showing visible power breaking points, and the door must be closed and locked.

hang the sign of no closing and be monitored by special personnel. (Liu Fengbin)

Peak pharmaceutical "enterprise information construction project" through the acceptance

The "Enterprise Informatization Construction Project" of Jianfeng Pharmaceutical Company was included in the list of key projects of "Integration of Industrialization and Industrialization" (high-level and in-depth combination of informatization and industrialization) in Jinhua City in 2015, and successfully passed the on-site acceptance of the expert group on the morning of May 18. The main contents of the "enterprise information construction project" of the pharmaceutical company include: the tank farm control system, which solves the problem of closed metering and transportation of organic solvents between the tank farm and the production area, can automatically realize the terminal metering setting, and effectively ensure the safety and environmental protection requirements of the tank farm operation; The air conditioning automatic control system realizes the control of the temperature, humidity and room pressure difference in the air conditioning area through the PLC digital-to-analog conversion of the upper computer and lower computer and the terminal actuator regulator, ensure the cleanliness requirements of the production area environment; The online particle monitoring software system automatically adjusts to the standard flow through the upper computer, vacuum system, laser sensor and isodynamic sampling probe, etc. through the flow detector device and key orifice plate inside each sensor, monitors the temperature, humidity, particles, planktonian bacteria, room pressure difference, etc., implements dynamic management, and realizes visual monitoring of the production process environment. MRP production management system, it makes it easier for the warehouse, workshop, and management personnel to obtain information about the flow of materials in the production process, the implementation of production plans, and product inventory. During the on-site acceptance on the 18th, the acceptance team composed of the Information Department of the Municipal Economic and Information Commission, the Economic and Development Bureau of the Development Zone, the Municipal Information Promotion Association and professors of Zhejiang Normal University checked the contracts of each system software, purchase and transfer records, training records, and problem records in project implementation,
