Risk Elements of Risk Goods Transportation in Summer
1. Driver elements. This risk mainly refers to the driver's mental relaxation, fatigue driving, and the second most important type of accident is traffic accident. In winter, the days and nights are long, the temperature is high, and the mosquito disturbs the drivers. Drivers are not well rested and easy to fatigue in driving. Sleeping and loose body have an impact on driving. Comprehensive logistics indicates that asphalt pavement exposure in winter is prone to "false light", which affects drivers'correct judgment of road conditions.
2. Elements of low temperature. Low temperature not only affects the driver's body and mind, but also has a slight risk to vehicle equipment and cargo.
1. The brake is broken. At low temperature, the brake bowl will shrink and deform due to low temperature, resulting in brake out of control. In the downhill, steep slope, frequent. Continuous use of brakes, brake failure is the cause of the accident.
3. Water temperature is too high. In the case of traffic jam or long idling time, the water thermometer of the initiator is too high, the task of high speed fan block is too long, and the music of the initiator is too loud, which causes serious damage to the initiator. Integrated logistics hints that when air conditioning is turned on at low temperature, the faults are as follows: idling speed is unstable, speed fluctuation is too large, the speed is strong when the speed is sharply decelerated, and the initiator has abnormal sound; the hot car can not start again after 10 minutes of stalling; the hot car sometimes automatically stalls when it is running; the cold temperature of space-time modulation of the cold car is very cold, the hot car's space-time modulation is not good, and the air conditioning is fragmented. There is a greater resonance buzz; when the hot car idles, the air conditioning compressor clutch sucks frequently and disconnects, forming the hot car air conditioning does not refrigerate.
4. Vehicle spontaneous combustion. With the addition of service life of vehicles, local components such as vehicle circuits are aging. At low temperatures, it is easy to cause auto-ignition of vehicle lines, and then cause vehicle damage.
5. Carrier goods ignite spontaneously or explode as a result of traffic accident collision. Under low temperature conditions, some of the risky goods are volatile, flammable and explosive, and are prone to serious accidents when exposed to open fire or violent collision.
