Detailed information on DS/PS-A human static discharge alarm:

In recent years, China's petroleum industry has developed rapidly, accompanied by frequent incidents of electrostatic accidents, causing significant economic losses and personal injuries. The causes of electrostatic accidents are not complex, but they have great concealment, which brings confusion and pressure to the safety management of enterprises.

The DS/PS-A human static discharge alarm is a new generation explosion-proof product designed for the petrochemical industry. It can intelligently detect whether the human body static voltage has been completely removed, and when the human body static voltage is at a dangerous value, it will emit an audible and visual alarm prompt.

It is made of specially designed conductive plastic material, which effectively extends the static discharge time, safely releases static energy, and ensures no electric shock or spark generation during human static discharge, completely eliminating the hidden danger of fire and explosion accidents caused by static electricity. And a special warning sign "Please eliminate human static electricity" has been specially designed, with a beautiful and generous appearance, providing strong support for enterprise safety production.

At present, the widely used static electricity elimination devices in China use stainless steel metal conductors directly grounded to eliminate human static electricity. This method uses discharge between conductors, which inevitably generates a large amount of electrostatic discharge energy and poses a great safety hazard of ignition discharge. From a safety perspective, it actually adds an extra layer“ignition”. Here, we suggest that you use the PS-A explosion-proof type to avoid the generation of static electricity hazards.

1. Thoroughly solve the hidden dangers of electrostatic ignition;
2. Effectively determine whether residual voltage in the human body has been completely eliminated;
3. Signs have a distinct warning function, making the visual warning system of enterprises more standardized;

The generation of static electricity often occurs during oil transportation,storageandload and unloadThe following are the most common places where products are used in these two stages:
1. Gas station unloading port;
2. At the entrance of the oil storage area and the upper tank ladder of the storage tank;
3. Outside the pump room door;
4. Oil delivery platform;
5. Beside the self-service fuel dispenser;
6. Other places that require the elimination of human static electricity, such as electronic factories, computer rooms, chemical plant entrances, etc.

1. Detection of static voltage range:- 15KV～ 15KV
2. Alarm voltage:>150V (human safety static voltage less than 500V)
3. Alarm method: Sound and light alarm
4. Power supply: lithium battery
5. Working temperature:- 40℃～ 60℃
6. Explosion proof grade: ExiaIIBT4

GB50074-2002 "Design Code for Petroleum Storage"
Article 14.3.13: Due to the widespread use of artificial fabric clothing, artificial fabrics are prone to static electricity, which often accumulates on the human body. To prevent sparks that may be generated by static electricity, it is necessary to install devices to eliminate human static electricity on the operating platforms that enter the light oil pump room, the top of the light oil tank, the light oil operation area, and the escalators or entrances in explosive hazardous areas.
