This document is the technical disclosure of construction safety in spring, including: disclosure content: when spring comes, everything will recover, which is the golden season of construction and production;However, spring is also a period of frequent fire and other safety accidents. This disclosure is specially prepared to prevent fire, casualty accidents and other potential safety accidents.1. Since it is relatively warm in spring, it is easy to cause fatigue (dozing). Construction workers should always wear personal safety protection equipment (such as safety helmets, safety belts, etc.). It is strictly prohibited to remove safety nets, "four entrances", "five edges" and other safety protection facilities without authorization.Therefore, the construction team is required not to force workers to work overtime, and it is prohibited to extend working hours at will.The on-site foreman shall often go deep into each working face to check whether there is any violation, and stop it once found.Fire prevention, object strike prevention, fall prevention and other safety protection measures shall be taken for special construction parts.When the foreman arranges the work, a person in charge must be appointed for the construction of more than two persons. The foreman of the construction team constantly carries out patrol inspection. Once paralyzed, the consequences are unimaginable.
