Gauge pressure instruments must eliminate three major hazards

Thread Content

Pressure instruments are common measuring devices that are widely used in various fields. It can visually display the pressure changes at various stages of the process, help understand the conditions that arise during the flow of products or media, monitor safety conditions during production, and through automatic interlocking or sensing devices, provide a rapid and reliable safety mechanism. It plays an important role in preventing accidents and protecting human life and property, and is thus referred to as the \"eyes of safety\". 　　However, in actual production and daily life, pressure gauges are sometimes neglected or used illegally, posing safety risks. The main issues are as follows: 1. The installation and configuration are not standardized. The current regulatory standards specify clear requirements for the configuration, installation, use, maintenance, and inspection of tables. In actual installation, there is a noticeable tendency to reduce the number of components in less critical areas or at dual/multiple monitoring points; disk diameter and range may not meet the requirements of the task; special instruments are used in environments with hazardous conditions such as flammability, explosiveness, toxicity, or corrosivity; and there are frequent deviations from the specifications established. 　　II. Lack of attention to daily use and maintenance. During use, no regular inspections or cleaning are carried out; there are no records of its usage, and issues such as hands that do not return to zero, severe fluctuations, damaged protective films on the explosion-proof holes, corroded dials or broken glass, and dirty dials are present. 　　III. Inspection and verification work is not carried out properly. The general calibration period for pressure gauges is half a year. Mandatory calibration is a legal measure to ensure the reliable technical performance of pressure gauges, accurate value transmission, and effective protection of safe production. Due to some users’ insufficient understanding of the safety functions of gauges, they fail to apply for calibration in advance, resulting in a serious problem of using them beyond their approved calibration period. In particular, newly purchased pressure gauges must pass calibration before they can be installed and used, yet the rate of calibration for these new gauges at the time of first use remains very low. 　　Compared to the production system, the pressure gauge is extremely small, and the gauge itself poses no danger. But with a pressure gauge as its core, supported by automatic interlock devices, sensing devices, and protection devices, and relying on delicate sensing as its vision, it forms a fortress for safety that is unmatched by anything else. A long dike can collapse because of an ant hole. Disregard and lack of attention to details are a desecration of safety. As one of the safety accessories, the pressure gauge is not merely used to display pressure values; it acts like a vigilant eye, monitoring even the slightest leaks, and constantly safeguarding the safety of the products, people, and the environment. Especially in hazardous environments such as those involved in the production, storage, and transportation of flammable, explosive, and toxic substances, pressure factors play a key role in preventing catastrophic accidents. The contribution of tables to security cannot be underestimated. 　　It is the responsibility of every safety professional to use pressure gauges properly. Firstly, the organizations using these devices must continuously enhance their safety and responsibility awareness, and properly manage and make use of the capabilities of these devices so that they can serve as a true substitute for eyes ； Secondly, testing and calibration institutions should carry out calibration work on instruments diligently, promptly downgrading or discarding those that do not meet the required standards, to ensure accurate measurement values and reliable performance ； Once again, regulatory authorities must enforce strict procedures and standards, focus their oversight on violations related to the use of forms, and take legal action against any improper operations or illegal uses. Let’s start with the details, build on a solid foundation, sharpen our focus on safety, and work together to create a strong barrier of security.
