The identification list of construction hazards mainly includes the following contents: workplace, operation activities, risk factors, possible dangers and control measures. The list of major hazards is a list derived from the list of hazards, which is also the above content.
First, the main hazards of the construction site main hazards
Major hazard sources on the construction site may cause injuries such as falling, collapse, object strike, lifting injury, electric shock, mechanical injury, poisoning and suffocation, fire and explosion.
According to relevant statistics, in the first half of 2006, the proportion of total deaths caused by building system accidents was: falling from a height accounted for 39.5%, construction collapse accounted for 22.6%, object strike accounted for 14.3%, lifting injury accounted for 8. 1%, electric shock accounted for 5.9%, mechanical injury accounted for 5%, and other types accounted for 4.6%.
Safety accidents in construction sites will not only cause casualties of construction and operators, but also affect nearby residents and even passers-by. Irregular construction units or contractors often have to pay heavy casualties. In addition, when a safety accident occurs, the damage to its construction facilities and existing projects is also a great loss.
Second, the major hazards on the construction site
(1) The major hazards existing in people are mainly people's unsafe behaviors, that is, "three violations": illegal command, illegal operation and violation of labor discipline, mainly manifested in inexperienced and low-quality personnel on the construction site. Statistical analysis of accident causes shows that more than 70% of accidents are caused by "three violations", so "three violations" should be strictly prohibited.
(2) Major hazards existing in the partial processes and operation of construction machinery and materials:
(1) Mechanical equipment overturning, structural collapse, casualties, etc. caused by the instability of scaffolding, formwork and support, tower crane, material hoist, installation and operation of construction elevator, manual digging pile, foundation pit construction, etc.
(2) High-rise buildings or working surfaces with a construction height of more than 2m (including high altitude, four-mouth and five-limb operations) cause accidents such as falling or falling objects hitting people below due to inadequate safety protection, construction waste piling up in the safety net, and people not wearing seat belts;
(3) Welding, metal cutting, impact drilling, rock drilling, etc. The safety protection of various construction electrical equipment (such as leakage, insulation, grounding protection and just one brake) does not meet the requirements, resulting in electric shock, local fire and other accidents;
(4) Stacking of engineering materials, components and equipment, frequent lifting and handling, and other accidents caused by various reasons, such as scattered piles, falling from high altitude, and injuries.
