Work classification of aerial work

1. The working height at height is divided into four sections: 2m to 5m, 5m above to 15m, 15m above to 30m, and 30m above.

2. The objective factors directly leading to the decline are 1 1:

1) The gust wind force is above level 5 (wind speed is 8.0m/s);

2) Grade II and above high temperature operation specified in GB/T 4200-2008;

3) Working environment with average temperature ≤5℃;

4) the contact cold water temperature is less than or equal to12℃;

5) The workplace is slippery with ice, snow, frost, water and oil;

6) The light in the workplace is insufficient, and the visibility is almost poor;

7) The distance between the operating range and the charged body of dangerous voltage is less than that specified in the table below; Voltage level /kV distance/m ≤101.735 2.063 ~10 2.5 220 4.0330 5.0500 6.08) A charged body with dangerous voltage swing, whose foothold is not a plane or only a small plane, that is, the diameters on both sides are less than.

9) Past strength of Grade III or above specified in GB 3869-1997;

10) working environment with toxic gas or oxygen content in air below 0. 195;

1 1) The working environment that may cause various disasters and accidents and the rescue of various disasters and accidents.

3. None of the above objective factors directly lead to falling. In the table below, work at heights should be classified as Class A.. If there is one or more items, it is classified as Class B. The classification is 2m ≤ h ≤ 5m ≤ h <15m15m ≤ h <; 30m h≥30m AⅰⅱⅲⅳBⅱⅲⅳⅳ
