Third-level education: entering a company (factory), entering a project department (workshop), and entering a work team.

The three simultaneities principle: design simultaneously, construct simultaneously, and put into use simultaneously. The three essentials: safety helmet, safety belt, and safety net. Three-level power distribution: main power distribution box, distribution box, and switch box. Four areas: stairways, elevator entrances, reserved openings, and passageways. Four principles to be adhered to: do not move on until the cause of an accident is identified; do not move on until those responsible have received training; do not move on until potential hazards are eliminated; do not move on until those responsible have taken action. Ten edges to be protected: the perimeter of foundation pits, the perimeter of balconies that still lack railings or guardrails, the perimeter of floors and roofs without external scaffolding for protection, the sides of scaffolding structures used in multi-level construction along staircases and stair sections, both sides of passages leading to buildings such as construction elevators or external scaffolding, the perimeter of floors in frame structure buildings, both sides of ramps, the perimeter of material platforms and cantilevered platforms, the edges of canopies and overhangs, and the perimeter of water tanks and water towers (perimeter of balconies, perimeter of roofs, perimeter of frame structures, outer side of unloading areas, runways, and ramp edges). Five inspections: inspect thoughts, management, potential hazards, rectification efforts, and accident handling. Five determinations: determine the person responsible for the rectification, the measures to be taken for rectification, the deadline for completing the rectification, the person who will complete the rectification, and the person who will conduct the acceptance check. Five types of inspections: routine inspections, professional inspections, seasonal inspections, inspections before and after holidays, and irregular inspections. Five signs: instructions, prohibitions, warnings, reminders; five boards and one diagram for electrical safety: the project overview board, the board listing management personnel and their contact numbers, the fire protection and security board, the work safety board, the board on civilized construction and environmental protection, and the general layout plan of the construction site. Six stages: Measure stage, Information dissemination stage, Education stage, Protection stage, Inspection stage, Improvement stage. Six to be eliminated: injury and death accidents, collapse accidents, object strike accidents, falls from heights accidents, mechanical injury accidents, and electric shock accidents.
