At present, the mechanism of lightning generation and how to effectively reduce the damage of lightning strikes remains to be studied. There are many accidents in the oil depots at home and abroad, but as long as the fire prevention and lightning protection facilities of the oil depot are safe and effective, the damage caused by them is not large.
The main cause of major accidents caused by lightning strikes is that some oil depots are poorly managed, there is a large amount of oil vapor, which reaches the explosive limit concentration, causing a big explosion and igniting a fire and forming a major accident.
Therefore, in addition to the lightning protection device in accordance with the specifications, the oil depot should normally maintain and maintain the valves and other equipment, reduce oil leakage, and often reduce the accumulation of oil vapor in the oil depot; in the thunderstorm, the suspension of the A, B and C oils is suspended. And work, close the port, take measures to reduce oil and gas emissions.

Reflective warning`s reflection part of the vest is the use of lattice micro-rhombus type refraction and high refractive index of glass beads back to the principle of reflection, through the post-processing of advanced processing technology made. It can reflect the distant light back to the light. Both in the day or night have a good retroreflective optical performance. Especially at night, it can play the same high visibility as the day. The use of this high-energy reflective material made of safety clothing, whether the wearer is in the distance, or in the light or scattered light interference, it can be relatively easy to be found by the night driver.
Reflective warning vests are made of high-visibility reflective material It can make the traffic police work smoothly in the night or special weather in order to reduce the rate of the casualties. it plays a special role in security especially in traffic engineering.When the motor vehicle fails, the driver needs to wear a reflective warning vest, and away from the faulty vehicle to prevent the occurrence of secondary accidents. This kind of reflective warning vest is mainly applicable to police, road officials, traffic commanders, road maintenance personnel, motorists, motorcycles and bicycles drivers, dark light workers and so on in one word, the local worker who needs to use light warning. Widely used in traffic engineering, shipbuilding industry, steel industry, machinery industry, oil industry, ambulance, parking lot, airport, traffic police and outdoor work or construction, plays an important role in good security warning .
When Car Reflective Vest use the aluminum lattice reflective material, not only in a small angle (from the reflective warning vest wearer far away), reflective brightness is high, even at a large angle (from the reflective warning vest wearer closer ), it still has a good reflective brightness, so that the locomotive driver earlier identified roadside vehicle side of the staff, as soon as possible to respond to effectively prevent the occurrence of secondary accidents.
According to reflective vest`s wearing [far distance discovers, near distance recognise" s character. It balances the big and small angle of optical performance. It has a large reflection angle.
