If the specified requirements are not met, protective measures such as setting up barriers, barriers and hanging eye-catching warning signs must be taken.

9. The setting of wire lines and the installation of electrical equipment at the construction site must comply with the requirements of the "Technical Specifications for Safety of Temporary Electricity at Construction Sites".
