4. Monitoring of operational anomalies in equipment
Method of screening: installation of equipment operational status monitoring systems, real-time monitoring of parameters such as vibration, temperature, current, etc. Of equipment; examination of abnormal sound, abnormal heat, aerobics, etc. At the time of operation of the equipment by hearing, touching, smell, etc.; analysis of equipment operating data, comparison of historical data and determination of potential malfunctions of the equipment。
Criteria for determination: the operating parameters of the equipment are beyond normal range, or the occurrence of abnormal sound, heat, odor etc. Is a security hazard。
Iii. “method” dimensions
1. Material storage conditions inspections
The method of screening is to check the temperature and humidity records of the warehouse to ensure that the material storage environment is in line with the requirements; to see whether the flammable explosive material is stored separately and at a safe distance from other items; and to check whether the material is stored securely, at a high level, and whether there is a risk of collapse。
Criteria: material storage environments do not meet requirements, or are poorly stored, with risks of collapse, leakage, fire, etc., considered to be safety hazards。
2. Material marking and warranty period verification
Method of screening: checking the clarity and completeness of the markings on the packaging of materials, such as names, specifications, quantities, production dates, shelf life, etc.; checking the timing of input of materials to calculate the remaining shelf life; and marking the isolation of obsolete materials。
Criteria: missing, unclear or obsolete material, risk of use, safety hazard。
3. Hazardous chemicals management inspections
Method of screening: to check the conformity of the procurement, transport, storage, use and disposal of hazardous chemicals; to see whether the storage of hazardous chemicals is equipped with appropriate protective facilities and emergency relief equipment; to check the accounts of hazardous chemicals to ensure conformity。
Criteria for determination: hazardous chemicals management does not meet requirements, such as failure to obtain relevant permits, poor storage conditions, incomplete billing, etc., and safety risks。
4. Material quality sampling
Quality testing for random extraction of a certain quantity of material to check whether material performance indicators meet standards; examination of material quality testing reports to confirm that the results are satisfactory; and quarantine treatment of substandard material。
Criteria for judgement: material quality does not meet standards and input use may affect production safety or product quality and is considered a safety hazard。
Iv. "fact " dimensions
1. Security management system review
(b) method of screening: organization of a comprehensive review by professionals of the existing safety management system of the enterprise, to check whether it covers all production chains and jobs; to see whether the provisions of the system are in compliance with national laws and regulations and industry standards; and to assess its operationality and effectiveness。
Criteria for judgement: the absence of a security management system, incomplete content or inconsistency with laws and regulations, and lack of operationality are considered security risks。
2. Inspection of implementation of protocols
(b) method of screening: the physical operation of an observer worker to check the correctness of the operating procedure against the operating protocol; a test to check the level of familiarity of the staff with the operating procedures, through on-site questioning or theoretical examinations; and a check to see whether the operating procedures are displayed in the visible location of the operation。
Criteria for determination: the failure of staff to comply with the protocol or to become familiar with it, as well as its lack of effective publicity, are security risks。
3. Emergency preparedness and exercise inspections
Methods of screening: checking whether enterprises have developed well-developed contingency plans, including all types of emergencies such as fires, explosions, poisonings; reviewing the records of the emergency response plans and confirming the timing, content, participants, etc.; assessing the effectiveness of the exercises and analysing whether the contingency plans need to be revised。
