1768-L45With the automation machinery and equipment is widely used in various industries of production and manufacturing and the improvement of relevant national safety regulations and supervision, the safety management of factory machinery has also been paid more and more attention. However, in the process of safety management of machinery and equipment to avoid industrial accidents, relevant managers often face various problems and confusion, such as: how to propose safety requirements when purchasing new machinery and equipment? Safety procedures have been established for existing machines, but accidents have occurred. According to what we have heard and seen, this paper preliminarily analyzes some reasons that hinder the realization of factory machinery safety goals, especially for some existing machinery and equipment, from the perspective of management and machinery safety standards.
Reason one: the lack of professional machinery and equipment safety assessment personnel
Many factories have an EHS department, which is often handed over to the department for safety evaluation of existing machinery or safety requirements for new machinery. However, it is not known that the work of EHS often focuses on the establishment of rules and regulations to ensure that the fire protection of the plant, the working environment, and the occupational health of employees comply with national regulations. The complexity and diversity of machinery and equipment itself, and the professional standards for judging whether there are safety defects in machinery and equipment, the combination of the two causes the EHS department, which was originally good at safety management, to become insufficient in professional technical knowledge and experience. Even if some of the personnel with both profession1768-L45al and technical knowledge and experience are occupied by other routine security management tasks within the department, they are unable to fully devote their work time.
Reason two: Machine equipment safety assessment personnel lack of cognition
Many people responsible for the safety assessment of machinery and equipment conduct safety evaluation or assessment only based on their own feelings or on some fragmented information, such as “there must be a sleeve for the shaft, there must be a cover for the wheel, there must be a fence, there must be a hole and there must be a cover”. However, the so-called “set”, “cover”, “column”, “cover” further requirements are at a loss, and its own lack of comprehensive and systematic learning and understanding of mechanical safety standards. This ultimately leads to the mistaken belief that existing protection is sufficient, such as using fixed protection but then not being able to perform LOTO before removing it, or using scram drawlines instead of more effective protection such as safety interlocks.
Reason 3: Use habit inertia or excessive pursuit of efficiency
This is a common problem when safety modifications are made to existing machinery and equipment. Due to the excessive pursuit of efficiency after the original use habits or security transformation, it leads to the habitual mistake of triggering or even artificial shielding of security protection. For example, habitual observation, reaching out to the loading and unloading area at the first time, using Type I hand control, etc. For such reasons, first of all, more effective safety improvement can be solved by increasing safety input, which is improved to Type III two-handed control than adding safety Windows1768-L45 or cameras. In addition, it must be understood that in the case of safety standards have been determined, in order to meet the safety standards of a specific machine and equipment, its minimum safety investment and even the highest production efficiency under the premise of ensuring safety has been determined. If you want to further ensure production, it must be solved by increasing personnel and equipment, or replacing machinery and equipment with more stable production. In short, efficiency, safety and commitment. After two of these factors are determined, the upper or lower limit of the last factor is determined.
