Requirements for Explosion proof Systems in Hazardous Chemical Warehouses

Basic infrastructure requirements for explosion-proof systems in hazardous chemical warehouses

1、 In terms of electrical facilities

Try not to install other electrical facilities in the warehouse. At the bottom of each warehouse wall, open a full set of blinds

Adequate ventilation requirements. If you want to install electric lights, exhaust fans, etc., you must choose the "Explosion proof Electrical Design, Installation

The explosion-proof products required by the Practical Manual of Maintenance, Testing and Safety Technical Standards and Specifications require the use of power cords

Galvanized steel water pipes should be sealed, and flexible explosion-proof pipes should be used for transition at the connection points. The sealing pipes should be properly grounded.

1. Explosion proof switches and sockets are best installed outside the warehouse.

2. The installation position of the exhaust fan is set at the bottom and top of the warehouse wall respectively, as there are many hazards

The vapor density emitted by chemicals is higher than that of air, and flammable vapor will accumulate near the ground. Bottom setting

A convenient device for extracting vapor accumulated on the ground.

3. Chemical warehouses should be equipped with thermometers and air conditioning to control the temperature inside the warehouse. The location of air conditioning should be far away from the intake and exhaust equipment, while meeting the requirements for electrical explosion-proof.

2、 In terms of fire-fighting facilities

1. Set up monitoring and detection systems such as surveillance cameras, toxic gas detectors, and temperature sensors.

The monitoring and detection system should also meet the requirements for electrical explosion-proof. Various parts of the monitoring and detection system

To connect to the fire monitoring room.

2. Install dry powder fire extinguishers and suspended dry powder automatic fire extinguishing devices.

3、 Other hardware facilities

1. A slope of about 10cm should be set up at the entrance of the warehouse to prevent flammable liquids from spreading when the packaging is damaged

Externally, encountering a fire source can cause a fire.

2. Install explosion-proof doors. Explosion proof doors should have high anti explosion strength and require the use of angle steel or channel steel

The frame of the door frame is made by assembling and welding the character steel, while the door panel is made of armor steel plate or boiler steel plate with high blast resistance strength

Make it.

3. There should be a drainage tank in the chemical warehouse, and the ground should be designed with a slope to collect leaked liquids into the drainage tank. The drainage tank should have a certain slope, and a collection tank (indoor or outdoor) should be installed at its end to facilitate the accumulation of liquid in the drainage tank. The collection tank should have a volume of one cubic meter and its structure should be leak proof. The collection tank is located at the corner of the wall and has an outlet on the wall for easy extraction of leaked chemical liquids. The collection tank should be sealed as much as possible to prevent the collected liquid from evaporating into the air, causing harm to the environment and posing a fire hazard.

4. Dangerous chemical warehouses must be equipped with protective equipment such as gas masks, chemical resistant gloves, chemical resistant shoes, and goggles for emergency preparedness.

5. Post warning signs and signs indicating the physical and chemical properties and disposal of hazardous chemicals.

6. Install lightning protection facilities according to specifications.
