With the development of the modern oil industry, on-site processing (chǔ lǐ) facilities are becoming more and more complex, resulting in more frequent opportunities to enter restricted space operations (oil). Restricted space operations in the industry are always considered to be one of the high-risk operations. The most effective way to secure the gas environment is to monitor the food, but many operators The risks that may exist in the confined space are not sufficiently recognized. The gas monitoring method is original and single, causing frequent incidents of personnel injuries due to restricted space operations, so we should make more reasonable conditions to develop a reasonable gas detection program ( Fāng àn). So what knowledge should the staff be familiar with before testing? Let's take a look at it together with it.

In order to ensure the safe and orderly conduct of the gas monitoring operation (WORK), the relevant knowledge (gas) of the gas monitoring personnel and the skills are strictly required. The noun concept, such as what ppm, the explosion limit, the nature of various hazard gases, and the possible hazards such as: burning, explosion, poison, suffocation, etc. The pipe gallery gas detector adopts imported gas sensitive components with high precision, high reliability, fast response and recovery time, good gas selectivity and strong anti-interference ability; LCD liquid crystal display, real-time display of gas concentration; small size and light weight Low power consumption and easy to carry; high-performance lithium battery, long working time, charging protection and low voltage protection, ensuring more reliable battery life and longer life; fast warm-up and fast response time.

In addition, Gas Monitor personnel need to be proficient in the use of gas monitoring equipment. The most commonly used portable four-in-one gas detection (inspection and test) detector in the petroleum industry can simultaneously monitor: hydrogen sulfide. , oxidation of carbon, flammable gas, oxygen. The pipe gallery gas detector adopts imported gas sensitive components with high precision, high reliability, fast response and recovery time, good gas selectivity and strong anti-interference ability; LCD liquid crystal display, real-time display of gas concentration; small size and light weight Low power consumption and easy to carry; high-performance lithium battery, long working time, charging protection and low voltage protection, ensuring more reliable battery life and longer life; fast warm-up and fast response time. The gas detector is an instrumentation tool for gas leakage concentration detection, mainly referring to a portable/handheld gas detector. Gas sensors are mainly used to detect the types of gases present in the environment, and gas sensors are sensors for detecting the composition and content of gases. The gas concentrations measured by most gas detection instruments are volume concentrations (ppm). According to China's regulations, especially the environmental protection department, the gas concentration is required to be expressed in units of mass concentration (eg, mg/m3), and our national standard specifications are also expressed in mass concentration units (eg, mg/m3;). The monitoring personnel should master the judgment of the gas detector's on/off, self-test, alarm and other issues, and keep it in a good state of full power.
