There are four requirements for hidden danger investigation. Hidden danger refers to personal injury or danger caused by people's unsafe behavior and management defects. Total production is to prevent the sudden change of its quality and inhibit the quantitative development of bad factors. Let's look at the four requirements for hidden danger investigation.
Four requirements for hidden trouble investigation 1 1. The hidden dangers of people are as follows:
(1) Employees do not follow the safety operation rules and operate illegally;
(2) Technical level and physical condition of personnel. Do not meet the requirements of their posts;
(3) Disregarding the habitual illegal operation and taking chances with the existence of hidden dangers;
(4) Employees do not wear personal safety protection articles correctly, or even give up using them.
2. The hidden dangers are as follows:
(1) The safety protection device of the equipment itself is missing, incomplete or damaged for a long time and needs maintenance;
(2) The equipment design is defective and does not conform to the principle of ergonomics, which may easily lead to misoperation of employees and accidents;
(three) the quality of safety protection devices and personal protective equipment is defective and can not play a protective role;
(4) Equipment, materials and tools are not stored and placed in the specified position, and there is no tool use record or incomplete record in the storage place;
(five) fire fighting equipment is unqualified or expired, and special equipment has passed the inspection period or has not been used for inspection.
3. The hidden dangers in the working environment are as follows:
(1) The lighting inside the factory building and workshop can't meet the requirements, the indoor temperature is too high or too low, and the ventilation is poor;
(2) Equipment placement and material stacking do not meet safety regulations and protection requirements;
(3) Various safety warning and indication signs are missing, unclear or confusing;
(4) The workplace is untidy, and production tools, finished products, semi-finished products, scraps, etc. are discarded at will, occupying fire exits and work areas, affecting the normal development of production work, causing confusion in the working environment and easily causing accidents;
(5) the use of electrical equipment is not standardized, and there is a phenomenon of private connection.
4. The hidden dangers in management are as follows:
(1) The rules and regulations related to production safety are not perfect or perfect;
(2) Management personnel's own safety quality is not high, or they only pay attention to production, turn a blind eye to hidden dangers of accidents, and lack supervision;
(3) Employees lack necessary safety education and training, resulting in poor safety awareness and unable to form a good safety culture atmosphere;
(4) In safety management, the rules and principles are replaced by human feelings and friendship;
(5) Supervisors at all levels can't explain clearly when they find employees' unsafe behaviors, and their attitude is bad and their tone is rude, which not only makes it difficult for employees to make mistakes, but also makes employees rebellious and continue to violate the rules.
The four requirements of hidden danger investigation 2 basic principles of investigation:
According to the enterprise's own characteristics, investigate the hidden dangers in hardware such as process system, infrastructure, working environment and prevention and control measures, as well as the weak links in software such as safety production system and mechanism, system construction, safety management organization system, responsibility implementation and accident investigation.
Basic methods of troubleshooting:
1, intuitive experience method. This method refers to relying on the observation and analysis ability of personnel, relying on experience and judgment ability to intuitively evaluate the danger of objects and judge possible accidents or occupational diseases.
2. Basic analysis methods. For an operation activity, the specific safety hazards in the operation activity are determined by comparing the unsafe state of objects, unsafe behaviors of people and management defects in hazard classification.
3. Work safety analysis method. This method divides an operation into several operation steps, and investigates the potential safety hazard of each step in the whole operation activity.
4. Safety checklist method. Use the prepared safety checklist to check the safety of the system and find out the potential safety hazards.
5. Safety standardization method. Safety standardization evaluates the management of equipment, site environment and occupational health and safety, and the investigation of hidden dangers can be carried out with reference to the evaluation table. The unqualified items in the evaluation form are potential safety hazards.
Four steps of hidden danger investigation and management
1. Establish a hidden danger management ledger, and specify the person responsible for rectification, the completion time of rectification, rectification measures and temporary preventive measures, rectification funds, acceptance criteria and acceptors, commonly known as "five determinations", and the hidden danger management ledger is also called "five determinations" table;
2. The person responsible for rectification completes the rectification according to the rectification measures (if temporary preventive measures are needed, they should also be implemented during the rectification) and reports to the inspector;
3. The inspectors evaluate the rectification of hidden dangers according to the acceptance criteria, agree to the closed loop of hidden dangers if the assessment is qualified, and rectify again if the assessment is unqualified;
4, quarterly and annual statistical analysis of enterprise hidden trouble investigation and management.
The investigation of hidden dangers requires the unsafe behavior of three people;
A, operation error, ignore the safety, ignore the warning:
1, start, shut down and move the machine without authorization;
2. There is no signal when the machine is started or shut down;
3, the switch is not locked, resulting in accidental rotation, power supply or leakage;
4. Forgot to turn off the equipment;
5. Ignore warning signs and warning signals;
6. Misoperation (misoperation of buttons, valves, wrenches and handles);
7. Running homework;
8, feeding or feeding speed is too fast;
9, the machine overspeed operation;
10, driving a motor vehicle illegally;
1 1, homework after drinking;
12, mixed passenger and cargo;
13, when the punch is working, put your hand into the stamping die;
14. Blow iron filings with compressed air.
Second, the safety device fails:
1. The safety device is removed;
2. The safety device is blocked and ineffective;
3. The adjustment error causes the safety device to fail;
4. others.
Third, use unsafe equipment:
1, temporary use of unstable facilities with potential safety hazards;
2. Use equipment without safety devices;
3. others.
Fourth, use hands instead of tools to operate
1. Operate by hand instead of hand tools;
2. Remove the debris by hand;
3, no fixture, the workpiece is processed by hand.
Verb (abbreviation for verb) goods are not stored properly
1, improper storage of finished products, semi-finished products and raw materials;
2. Improper storage of tools and chip production supplies;
3. others.
6. Adventure into a dangerous place
1, close to material leakage (without safety facilities);
2, logging, skidding, transportation, loading, did not leave the dangerous area;
3. Entering the confined space without the permission of the safety supervisor or guardian.
