Causes and accidents in the use of "Cranes"
preventable due to two reasons:
– unsafe conditions
– unsafe operations
indefensible will occur only 2% is natural disaster
unsafe conditions It is the cause of about 10% of all accidents. The origin of the cause may be categorized from three elements.
– The machine is in an unsafe condition, such as no safety equipment. incomplete braking system, etc.
- working area in an unsafe manner, such as a runway with a bumpy road surface Work near Lat Khan The condition of the area is unstable, strong, etc.
– The person does not wear personal protective equipment. Dress is not tight, etc.
unsafe work practices (Unsafe acts) account for approximately 88% of all accidents. Which is considered a major cause of accidents. derived from three components
– Lack of knowledge is a very serious cause of accidents. Because operators lack knowledge about safety at work, such as lack of knowledge about operating the crane. Lack of knowledge of binding devices moving material Can't calculate the size of the leg pads, etc.
– Risk. The operator has good knowledge of safety but likes to operate with risks such as overloading cranes. Operate with unreasonable urgency, short-cut steps, do not use safety aids, for example, use PTO2 against weak ground conditions, but use small steel plates to support crane legs. or did not survey the area before operating the crane without assignment playing fiery while working, etc.
– Incorrect attitude, such as having the feeling that the accident happened because of bad luck, bad luck, bad luck, etc., therefore did not find a way to prevent accidents

由于两个原因可以预防:
– 不安全的条件
– 不安全的操作
站不住脚只会发生 2% 是自然灾害
不安全条件 它是所有事故的大约 10% 的原因。原因的起源可以从三个要素分类。
– 机器处于不安全状态,例如没有安全设备。制动系统不完善等。
- 以不安全的方式工作的区域,例如路面崎岖不平的跑道 在 Lat Khan 附近工作 该区域的条件不稳定、坚固等。
