As the protector of high-altitude operators, the reason why the differential fall arrester can protect the safety of operators is not only related to the quality of the differential fall arrester, but also related to the formal use mode. Harsh environment will seriously affect the life safety of high-altitude operators. Even if the quality of differential fall arrester is good, high-altitude operation in harsh environment is not allowed.
There are strict regulations on high-altitude operation. It is strictly prohibited to carry out high-altitude operation under the condition of strong wind above level 5 (including level 5). At the same time, high temperature, rain and snow will also increase the potential safety hazards of high-altitude operation, which is also prohibited. Then is the normal operation of the differential fall arrester. When using the differential fall arrester, remember to hang it high and use it low.
The differential fall arrester can complete self-locking within 0.2 seconds at the moment of the operator's slip, that is, under the gravity acceleration of 9.8m/s, the falling distance is within 0.2m, the impact force generated is about 3000n, and will not cause any harm to the human body. These are on the premise of high hanging and low use.
If you do not choose to hang high and use low in the process of use, the falling distance will exceed 0.2m, resulting in greater impact, which will not ensure the safety of users. It is forbidden to drink alcohol before working at height, which will seriously affect the response ability of the brain, thus greatly increasing the potential safety hazards. At the same time, it is also forbidden to work at height in case of illness.
Therefore, the life safety of high-altitude operators should not only consider the quality of differential fall arrester, but also consider environmental factors, formal operation and their own physical conditions. Only in this way can the life safety of every high-altitude operator be guaranteed.
