Thread Content

In safety management, safety documentation, and safety presentations, the safety techniques, procedures, methods, and control measures related to construction projects are often summarized in brief terms known as “safety acronyms.” These acronyms are concise, but they sometimes make it difficult to remember what they specifically refer to. The editor has now compiled and organized the following information for reference by on-site construction safety managers. A concise safety guideline: One machine, one box, one switch, one leakage protector. This refers to the requirements regarding electrical safety for machines and equipment on site: each electrical device should have its own dedicated switch box, which contains a disconnect switch (one switch) and a leakage protector. One certificate and two documents: This refers to the requirement that materials used in construction must come with an official factory (safety) certification, a material certification document, and a test report showing successful on-site inspection. Dual responsibilities for one position: In construction projects, this refers to the fact that a specific job role entails two types of responsibilities, emphasizing the safety responsibilities associated with that role – that is, its regular job duties – as well as its safety-related obligations. 　 Two-key safety shorthand: The two certificates refer to the \"Safety Qualification Certificate\" and the \"Job Skill Certificate\" that must be held by the person in charge at the site, safety managers, or technical personnel. Two don’ts and one must: In construction, it is essential to firmly uphold the principles of \"leaving no regrets, avoiding becoming a culprit, and building enduring projects.\" Three-character safety shorthand: “three wastes” refers to “wastewater, waste gas, and solid waste” that must be properly handled in environmental protection. Three types of control: Refers to the controls implemented during the construction process: pre-control, in-process control, and post-control.

Three electrics: namely electricity, telecommunications, and radio and television facilities. The principle of \"three simultaneities\" refers to the requirement that environmental protection and soil and water conservation measures in project construction be carried out simultaneously with the main construction work of the project – that is, they should be designed, constructed, and inspected at the same time. It must be done all at once, without leaving any lingering problems. Three processes: This refers to the requirements for workers during each stage of construction – to check the previous process, ensure the quality of the current process, and support the next stage of work. The “Three Fixes” system: This refers to the system of “assigning specific personnel, designating specific machines, and defining job responsibilities” in the management of machinery and equipment. The three no’s for handover: These refer to the handover between different construction stages – no handover without self-inspection records, no handover until acceptance is completed, and no handover unless important sections have been approved by the supervising engineer. Three musts: Every process has standards, every standard is subject to inspection, and every inspection yields a conclusion. Three-level power distribution: referring to the three levels of the power supply system, namely main distribution, distribution, and switch boxes. Safe electricity use requires three-level power distribution with protection at each level. Three connections and one leveling: The conditions that must be met at the construction site before work begins: accessible roads, available water supply, accessible electricity, and a leveled ground surface. Regarding the “five utilities and one leveling”: Communication (including networks) and ventilation should also be included ； If we talk about the “seven connections,” postal services and heating supply should be added as well.

The three-stage seven-step method refers to the excavation technique for tunnels in soil layers or unstable rock masses, as well as for tunnels with large cross-sections. It is based on the principle of excavating arc-shaped pilot tunnels while retaining the core soil.
