The Central Meteorological Observatory issued a rainstorm yellow warning at 06:00 on July 12

   It is estimated that from 08:00 on July 12 to 08:00 on July 13, there will be heavy rain in Beijing, Tianjin, northern Hebei, southeastern Inner Mongolia, western Liaoning, northern Shandong, Northern Jiangsu and Anhui. Among them, there will be heavy rain in some areas of northeastern Beijing, northeastern Hebei, western Liaoning, and local heavy rain (250-280 mm) in northeastern Hebei.

   Some of the above areas are accompanied by lightning, short-term heavy rainfall and gale weather. The maximum hourly rainfall is 30-50 mm, and the local rainfall can exceed 80 mm. The gust is about 8, and the maximum rainfall can reach 10-11.

   In view of the current flood control situation, according to the relevant provisions of the "national emergency plan for flood control and drought relief", the State General Administration of flood control launched the level IV emergency response for flood control at 17:00 on November 11, and sent three additional working groups to Shanxi, Hebei, Beijing and other places to assist in the prevention and response of heavy rainfall. In the face of flood season, how can dangerous chemicals enterprises spend the flood season safely? Xiao Han has come to help!

Strictly implement the main responsibility of enterprises

Fully understand the characteristics of the weather in the flood season, strengthen the dual prevention mechanism of risk identification and hidden danger investigation, carry out self inspection and self correction, and effectively control the hidden danger of accidents.

Consciously bring it into early warning system and standardize management

Do a good job in recent major hazard source supervision and self inspection and risk assessment of large oil and gas storage facilities. Standardize the access to the safety production risk monitoring and early warning system to ensure that the online rate of enterprise video and data reaches the standard.

Regular inspection of key equipment

Comprehensive inspection of lightning protection and anti-static and flood control, ventilation, rain proof facilities, production area drainage system, storage tank area temperature and pressure detection and spray cooling system, all kinds of detection and alarm equipment.

Standardized storage of various materials

Consciously implement the storage specifications, check the flood control capacity of hazardous chemicals storage facilities, timely rectify the existing potential safety hazards and problems, and strictly prevent the occurrence of loss or leakage of hazardous chemicals.

Strictly control key substances

Take good care of highly toxic chemicals and substances that react with (wet) water. The control measures of cooling, ventilation and moisture-proof shall be strictly implemented for spontaneous combustion and autocatalytic substances, and it is strictly forbidden to discard and store them at will.

Comprehensively check the potential risks of oil and gas pipelines

Conduct comprehensive investigation on geological hazards along the pipeline, quality defects of circumferential welds and other hidden dangers, and strictly prevent accidents such as leakage of dangerous chemicals.

Pay attention to early warning and keep emergency state

Pay close attention to the disaster warning information, improve the emergency plan, regularly drill and train, improve the ability of employees to handle and self rescue in advance, and strictly implement the 24-hour special person duty system in the duty room (central control room).

Scientific management of front line operators

We should reasonably organize production according to law, strictly control overtime work, and do a good job in heatstroke prevention and personal protection for grass-roots front-line workers, so as to avoid production safety accidents caused by excessive fatigue.

As the leader in the research and production field of laser monitoring technology, Hanhai photoelectric laser products are the industrial products of major national scientific research achievements of CAS. The technology is "domestic leading and international advanced", with comprehensive advantages in many aspects, and can meet the requirements of storage monitoring of dangerous chemicals to the greatest extent.

Laser absorption spectroscopy is the most advanced gas detection technology in the world. Hanhai photoelectric system holds the research achievements of laser absorption spectrum detection, and is the leader in technology and market application in this field. Products and technologies are always in the forefront of the research and development and application of laser spectrum technology in the world, and have the overall advantages of domestic and international advanced recognized by the former State Administration of safety.

Compared with the traditional dangerous gas monitoring method, the main advantages of laser gas detection technology and products are: the laser is the working principle, which can realize large-scale, regional, active and high sensitivity monitoring, and anti electromagnetic interference; The specific monitoring point does not need power supply and oxygen for chemical reaction, and can ensure the essential safety by normal monitoring in the hypoxia environment of plateau. The essence of the existing technology is improved in the aspects of monitoring accuracy, reaction speed, operation and maintenance cost, convenience of use, and long service life. The advantages of maintenance free, no calibration and simple operation of monitoring equipment can be realized, and the cost can be reduced and economic performance can be improved.
