What are the risks and protective measures for aerial work?

1. The main hazards are falling factors, as follows:

(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 Insufficient light and poor visibility in the workplace;

⑦ The distance between the operating range and the charged body with dangerous voltage is too small;

⑧ Swing, the foothold is not a plane or just a small plane, that is, a rectangular plane with either side less than 500mm, a circular plane with a diameter less than 500mm, or other planes with similar shapes and sizes, which makes the operator unable to maintain normal posture;

Pet-name ruby GB 3869-1997 provisions of grade III or above physical labor intensity;

Attending the working environment with toxic gas or oxygen content in the air below 0. 195.

2. The control measures are as follows:

(1) when entering the site, you must wear a safety helmet, fasten your hat belt, and use personal labor protection articles correctly;

(2) Suspended workplaces should have a solid foothold and must be equipped with protective nets, railings or other safety facilities according to specific conditions;

(3) Rigging, scaffolding, hanging baskets, hanging cages, platforms and other equipment used for suspended operation can only be used after technical appraisal or inspection;

(4) Before working at heights in building construction, check and accept the safety protection facilities item by item. Aerial work can only be carried out after acceptance. Acceptance can also be carried out in layers or stages;

(5) Safety protection facilities shall be checked and accepted by the project leader of the unit, and relevant personnel shall be organized to participate;

6. The acceptance records of safety protection facilities shall be checked item by item by category. Anyone who does not meet the requirements must be repaired and qualified before inspection. Regular spot checks should also be conducted during the construction period.
