Basic Safety Rules for Explosion-Proof Electrical Construction (shared by Shenzhen ZhongNuo Inspection Technology Co., Ltd.)
Explosion-proof electrical installation differs from standard electrical installation due to the increased explosion-proof requirements of its environment. In accordance with industry standards, an environment where gases, vapors, mist, or dust mix with air under atmospheric conditions and, upon ignition, the combustion spreads to all unburned mixtures is termed an explosive environment. An area where a large number or a number expected to occur of explosive gas environments or flammable dust environments necessitates special preventive measures for the structure, installation, and use of electrical equipment is called a hazardous area. Explosion-proof electrical installation refers to a task that meets explosion-proof electrical, environmental, and personnel requirements, conducted in explosive environments and hazardous areas, and is highly critical.

Shenzhen Zhongnuo Testing Technology Co., Ltd. offers explosion-proof engineering construction services in the field of:
Explosive gas environments and hazardous areas with explosive or flammable dust exist in various industries and fields, including petrochemicals, metal smelting, fine chemicals, petrochemical ground facilities (gas stations, refueling stations, petrochemical storage and transportation, etc.), new energy, special equipment, nuclear power, tunnels, grain processing, wood processing, metal component manufacturing, environmental protection engineering, and more. Ensuring explosion-proof safety in these dangerous areas safeguards the防爆 safety of hazardous explosive sites, protecting the economic development of our country and its people.

General Requirements for Explosion-Proof Workshop Design (Shared by Shenzhen ZhongNuo Inspection Technology Co., Ltd.)
4.1 Floor, Interior Wall
Areas producing flammable gases heavier than air or vapors of flammable and combustible liquids, as well as Class B production areas with dust and fiber explosion hazards, should use non-sparking floors. To prevent sparks, the floor can be made of rubber, plastic, rubber mixed with graphite, or asphalt concrete.
Interior walls of workshops where combustible dust may settle should be plastered or painted to create easily cleanable (washable) surfaces.
4.2 Office, Break Room
For personnel safety, do not establish offices or restrooms in Class A or B production buildings with explosive hazards. If necessary, such rooms may be located outside the workshop, separated from the workshop by non-combustible walls with a fire resistance of not less than 3.5 hours.
4.3 Electrical Equipment
Electrical equipment in explosion-proof workshops should be selected and installed according to different conditions, using explosion-proof types such as explosion-proof switches, explosion-proof motors, and explosion-proof lighting fixtures, and strictly avoiding non-explosion-proof types.
4.4 Lightning Protection Facilities
In facilities and workshops prone to explosion, in addition to installing lightning protection devices on the building itself, it is necessary to set up lightning rods around the building as required, ensuring the structure is within the protected range of the entire lightning protection system, thereby preventing accidents caused by lightning strikes.
