Teach you how to manage and control mechanical risks

Risk management

Last time, we talked about the content of the first step of risk assessment - risk analysis, and learned that the risk analysis needs to evaluate the equipment and understand the identified risk factors. In this episode, we continue talking about the second part -- risk 

management.

In theory, risk management includes two aspects, the management of machinery and equipment and the management of personnel themselves, which is the focus of the industry is also difficult.

Machinery and equipment management

The management of mechanical equipment is simply that the machine needs to have a certificate when it is started. For example, a tour guide needs a tour guide certificate to enter the line, and a planner needs a planner certificate to enter the post.

In principle, every operation entering a hazardous area can be divided into the following two situations:

① Routine operation: for processed products

② Special operations: for equipment, such as equipment inspection and maintenance.

In order to ensure the safety of the plant and personnel, in general, special operations need to close the energy markup lock, commonly known as LOTO, which belongs to the responsibility of the equipment user; Conventional operation protection is not able to close the equipment, so the equipment needs to have mechanical protection, which is the responsibility of the equipment manufacturer.

Then our difficulty turns to the need to ensure that each hazardous area has an independent certification to ensure that the mechanical protection design is qualified.

For example, mechanical protection is the assessment index of the certificate, then the reliability of the safety loop in mechanical protection, the timeliness of protection, the integrity of protection, and the prevention of accidental start represent different types of sublevels of mechanical protection.

In this case, all equipment manufacturers should ensure that each type of sub-level assessment indicator is qualified before delivering the product to the user.

The management of people themselves

To protect the safety of the personnel, it is necessary to stipulate that the operator strictly abide by the following points:

1, before the actual operation need to go through professional training, certificate on the job;

2. Wear safety protective items and take protective measures, such as wearing safety helmets, protective glasses, dust masks;

3, do not change clothes next to the starting mechanical equipment to avoid being involved in accidents; When operating the drilling machine, do not wear gloves, etc., the specific common accident diagram can refer to the following:

Of course, for personnel on the mechanical production line, safety protection products will be particularly important than the protection of personnel themselves. Therefore, when selecting safety protection products, equipment users should choose products that meet mechanical safety standards!

As a professional industrial safety system integration service provider, Dorn Technology focuses on the evaluation, design and implementation of machine safety protection Ple level system, in strict accordance with international safety standards, to provide assistance for the overall construction of smart factories system-level safe and efficient production, products in line with EU standards and Chinese standards, and through the corresponding certification.
