    Precautions for high altitude operation of chimney

    1、 Definition of work at height

    Work at height: any work at a height that is likely to fall at a height of more than 2 meters (including 2 meters) from the falling height datum plane, or if there are injury factors under or near the slope with a gradient of 45 degrees in the operation section, it is regarded as high-altitude operation.

    2、 Safety requirements for work at height

    1. Those who are engaged in high-altitude operation must apply for "work at height certificate" and implement safety protection measures before construction.

    2. The examination and approval personnel of work at height certificate shall go to the site to check and confirm the measures before approving the certificate.

    The personnel working at heights must receive safety education and be familiar with the site environment and construction safety requirements. 3. 3. Before high-altitude operation, operators shall check the "work permit at height" and carry out construction only after safety measures are checked and confirmed. Otherwise, they have the right to refuse construction.

    4. Workers at height shall wear labor protection articles according to regulations, and check before operation, and correctly use falling prevention articles, climbing appliances and equipment during operation.
