What are the challenges in achieving machinery safety?

With the wide application of automated machinery and equipment in various industries of production and manufacturing, as well as the improvement of relevant national safety regulations and supervision, factory management has paid more attention to the safety management of machinery and equipment. In the process of trying to manage the safety of machinery and equipment to avoid industrial accidents, managers often face various problems and confusion. For example, how to put forward safety requirements when purchasing new machinery and equipment, and why accidents occur despite the fact that safety procedures have been established.

In this issue, we will analyze the reasons that prevent factories from achieving their machinery safety goals, especially for existing machinery and equipment, from a management perspective and in conjunction with machinery safety standards. Hope to provide some ideas for everyone's mechanical safety protection.

Reason 1: Lack of professional machinery and equipment safety assessment personnel

Many plants have an EHS department, which is responsible for the safety assessment of existing machinery or the safety needs analysis of new machinery. Generally speaking, the EHS department is good at ensuring that the fire protection, working environment and employee occupational health of the plant comply with national regulations through regulations. However, assessing whether a machine has a safety defect requires not only technical expertise, but also experience, because the machine itself is complex and diverse. For the EHS department, professional machine and equipment safety assessment personnel are relatively scarce. Even if some personnel have professional technical knowledge and experience, they are often unable to fully devote themselves to the machine and equipment safety assessment work due to the need to deal with routine safety management tasks within the department.

(*EHS - abbreviation for Occupational Health, Safety Management, Health Management. Mainly responsible for the company's occupational health of employees, the company's fire safety, the company's health conditions, the company's environmental policy, etc.)

Reason two: Machine equipment safety assessment personnel lack of cognition

Many people responsible for assessing the safety of machinery and equipment often do so on a hunch or based on fragmented information. For example, safety production "four will be proverbs - there will be a shaft set, there will be a wheel cover, there will be a column, there will be a hole cover", has summarized the main points of mechanical safety protection, but some people on the "set", "cover", "column", "cover" and other specific requirements lack of understanding, lack of comprehensive systematic learning and understanding of mechanical safety standards, This ultimately leads to misjudgments about the adequacy of existing protection measures, resulting in a situation where protection is present but inadequate. For example, the use of emergency stop rope instead of safety interlock this measure, for safety production buried hidden dangers.

Reason 3: Use inertia or excessive pursuit of efficiency

This is a common problem when making safety modifications to existing machinery and equipment. Due to the original use habits or excessive pursuit of efficiency, resulting in the habit of accidentally triggering or even artificially shielding the safety protection device. For example, habitual observation, habitual reaching to the loading and unloading area, etc. In response to such problems, more effective safety improvement measures can be taken by increasing safety investment, such as increasing safety Windows or safety light curtains, etc. Once external objects are detected to enter the prohibited area, the equipment can be stopped immediately to avoid collision or damage to the equipment.

GM series safety light curtain has the advantages of high safety, reliability and flexibility, and easy installation and maintenance, is widely used in automated production lines, warehousing logistics, machinery and equipment and automotive industry and other fields, to meet all the requirements of dangerous machinery that need to set up personal protection areas.

In summary, in the case of safety standards have been determined, in order to meet the requirements of the safety standards of machinery and equipment, the minimum safety investment and the highest production efficiency under the premise of ensuring safety have been determined. In order to further improve production efficiency, it must be solved by increasing personnel and equipment or replacing machinery and equipment with higher precision and more stable.

For the protection and safety of existing equipment, we must rely on the precise operation of professionals, and require users to strictly comply with the requirements. There is no reason to reduce the standard of safety protection measures, because safety production is the cornerstone of the normal operation of enterprises, only to ensure the safety of employees and equipment, enterprises can maintain normal production and achieve better development.
