Discussion on Development Trend of Anti-static Protective Clothing from Safety Regulations and Policies

Static electricity is one of the main factors in inducing industrial workers' occupational diseases and threats to safe production. Static electricity prevention has also received increasing attention. Besides the explosion caused by the accumulation of static electricity, the harm to the human body is also enormous: the high static electricity can change the normal potential difference of the human body surface, hinder the normal ECG conduction, and the long-lasting static electricity will also make the blood alkaline rise. As a result, calcium levels in the serum decrease, and calcium excretion increases, causing skin itching and pigmentation, affecting the body's physiological balance, and disturbing people's emotions.

With the rapid development of the economy and the gradual improvement of people’s living standards, the operating conditions of industrial workers have been greatly improved, but various types of safety accidents are still an important threat to the safety of industrial workers and the safety of state property, constantly reminding us of occupational safety. The importance of protection.

At present, relevant state departments continue to issue relevant laws and regulations and improve the safety protection system for industrial workers. The editors focused on the recent introduction of several regulations and regulations, listed some of them related to electrostatic protection regulations, and hope to discuss the development direction of anti-static protective clothing.

Article 4 of the "Law of the People's Republic of China on Prevention and Control of Occupational Diseases" stipulates: Laborers shall enjoy the right to occupational health protection in accordance with the law. Employers shall create working environments and conditions that meet the requirements of national occupational health for workers, and take measures to ensure that workers receive employment. Health protection.

Article 26 stipulates: For occupational disease prevention equipment, emergency aid facilities and personal protective equipment used by individuals, the employer shall perform regular maintenance and inspections, regularly test its performance and effects, ensure that it is in a normal state, and may not dismantle it without permission. Or stop using it.

According to Article 18 of the "Safety Regulations for Coalbed Gas Surface Mining (Trial)", the gas layer enterprise shall establish a system for the provision, use, and management of labor protection articles and provide employees with labor protection articles that meet national or industry standards.

Coalbed methane enterprises shall train employees in the use of labor protection articles, guide and educate employees to properly wear and use labor protection articles;

Article 202 When cleaning equipment and appliances, the following requirements shall be met: (3) It is forbidden to use chemical products such as chemical fiber, plastics, silk, etc. to easily generate static electricity to wipe objects and equipment;

Article 203 Dressing and anti-static should comply with the following requirements: (1) Entering explosion-hazardous places, wearing anti-static clothing with work safety signs, cotton overalls and anti-static shoes;

AQ4115-2011 "General Guideline for Prevention of Electrostatic Discharge of Fireworks and Firecrackers" was implemented on December 1, 2011. Article 6.3.1 of this guideline clearly states: Inflammable and explosive places, operators are strictly forbidden to wear synthetic fibers, silk, wool and other materials. Clothing should wear anti-static overalls (see GB12014) or cotton overalls.

Article 5 of the “Measures for Measures for Preventing Heatstroke and Cooling Down Measures” stipulates: (4) Provide workers with necessary high-temperature protective equipment and personal protective equipment that meets the requirements, and strengthen the maintenance of high-temperature protective equipment and the management of personal protective equipment.

In view of the relevant provisions of the regulations, it can be seen that the state will increase the awareness of safety production and protect the safety of life and property of industrial workers. The application of labor protection products will also become more and more widespread. In order to protect the health and safety of industrial workers, occupational safety protective clothing is indispensable for wearing, but a single anti-static function can no longer meet the current demand for protective clothing in various industries. The Law of the People's Republic of China on Occupational Disease Prevention explicitly mentions that the State encourages and supports the development, development, promotion, application of new technologies, new processes, new equipment, and new materials that are conducive to the prevention and treatment of occupational diseases and the protection of the health of workers, and strengthens the mechanism of occupational diseases. Regular basic research has taken place, and from the "Measures for Measures for Preventing Heatstroke and Cooling Down Measures," we can predict that future anti-static occupational safety protective clothing will have a cooling tendency.

At present, anti-static fabrics basically only have the most single anti-static function, heat dissipation and cooling type anti-static fabrics are not many, multi-functional combined anti-static occupational safety protective clothing is a new requirement of the industry for occupational safety protection of industrial workers, I believe Continuous research and development and promotion of multi-functional anti-static professional safety protective clothing will be the main direction for the future development of functional business wear.

Drilling BOP And Control System

During oil drilling, it is installed on the wellhead casing head to control high-pressure oil, gas, and water blowout devices. When the oil and gas pressure in the well is high, the blowout preventer can close the wellhead (shut down). When the heavy mud is pressed into the drill pipe, there is a four-way under the ram, which can replace the mud invaded by gas, increase the pressure of the liquid column in the well, and suppress the ejection of high-pressure oil and gas.
Its types are divided into ordinary blowout preventer, universal blowout preventer and rotary blowout preventer. The universal blowout preventer can be activated in emergency situations to deal with any size of drilling tools and empty wells; the rotary blowout preventer can realize the blowout and drilling operation. In deep well drilling, in addition to two ordinary blowout preventers, universal blowout preventers and rotary blowout preventers are often added, so that three or four combinations are installed at the wellhead.
Annular Blow-out Preventer Annular Blow-out Preventer is usually equipped with a large gate with a ram-type blowout preventer. During operation, a sealed annular space is formed between the pipe string and the wellbore. When there is a pipe string in the well, it can also be separated The well is closed, but it will not work after several times of use, and long-term shut-in use is not allowed.
