Safety technology for formwork installation

1. Operators entering the construction site must wear safety helmets and buckle the headbands. Operators are strictly forbidden to wear hard soled shoes and heels for homework

2. Guardrails should be set up at heights and near the edge of the hole. Zhang an 4. The accessories of the experimental machine are natural. If there is no reliable protection method on December 18, 2013, you must wear safety belts and buckle them.

3. Before the task, check whether the things used are secure.
