There are certain risks in the air compressor room, some of which stem from the process of operating and maintaining compressors and other equipment, while others stem from factors such as safety awareness and the working environment。Therefore, only by paying attention to the safety risks in the air compressor room can we effectively manage the risks, provide a good safety environment for the normal operation of the compressor, prevent the occurrence of equipment accidents and personal accidents, and ensure that safe production can be realized。So, what risks exist in the on-site management of air compressor station？Bolet compressor Xiaobian collated the following content:

The harm in the air compressor room-- Falling from a height

Our compressor station is a standard factory design with a height of approximately 10 meters。Although many pipe exits are about 5 meters apart and many operations require shelving, operations that are more than 2 meters above the base level (including 2 meters) are called high work。To carry out high altitude operations, you need to hold a high altitude operation certificate, and you must undergo special training and pass the qualification examination to become a special operator and obtain the "Special Operation Certificate of the People's Republic of China".。These people must obtain relevant certificates before starting work。

Getting certified is just the foundation, but more important is having a clear understanding of the risks of working at altitude。In order to ensure the safety of working at altitude, the safety belt must be used correctly and supervised when necessary。Safety guardians also need to protect themselves from falling objects from high places。At the same time, the duty of guardianship must be performed honestly, not half-heartedly。Although some companies have safety guardians for working at altitude, these guardians may think that they are not involved in working at altitude themselves, so there is no need to worry, and will be downstairs playing with their phones, it seems that they are often busy with other things。

The hazards in the air compressor room - heat stroke

Heat stroke is a risk that can occur in high summer temperatures, especially if you have high blood pressure or are older。This group is less resistant to high temperatures and more susceptible to heat stroke。With the increase of abnormal weather events, factories are required to strengthen the management of high temperature environment。

First, the ambient temperature of the building can be reduced by ventilation。Second, you can reduce the time spent performing heavy physical labor, working in confined Spaces, and in unusual locations。In addition, provide water and other cool drinks to rehydrate employees in a timely manner。Employees can also be trained in first aid knowledge related to heat stroke to ensure that they can timely rescue and rescue in the event of heat stroke and other situations。

Damage in the air compressor room - mechanical damage

Mechanical injury is the most common type of injury in places such as air compressor stations。This is because if someone accidentally touches the machine while it is running or operates it improperly, it will cause mechanical damage。

In a previous post, I mentioned a serious mechanical accident that occurred last year。In the accident, the victim did not follow the instructions of the foreman on duty to check whether the wind lock was locked, but started the hydraulic press, and the "mode lock" could not be implemented。According to the "Mold" working chapter of the "Safety Risk List", the control measures of "check whether the air clamp is flexible before installing the clamp, and the installation process is monitored by professionals" must be adopted, used and maintained。Through this procedure, the operator cannot rely solely on the interlocking parts of the device, but mainly on visual inspection。The purpose of this regulation is to prevent accidents in which the movable beam of the hydraulic press is stuck with the die and engages the dovetail。Unfortunately, the machine broke, and a piece of moldy dovetail flew through the crack and hit his left leg, causing a ruptured artery, excessive blood loss, and eventually died in hospital。

There are two main ways to control the risk of mechanical injury。The first is to enforce control through locking and tagging。For example, coverings can be used to prevent rotating parts from directly harming people, while locks can also be added to solve the problem of exposure。In addition, we must abide by the rules and regulations and prohibit illegal operations。Only the correct shutdown operation can ensure personal safety and equipment safety。

The harm in the air compressor room - lifting injury

Some parts of large compressors are very heavy and difficult to transport by hand during maintenance operations, requiring the use of a bridge crane within the plant。Cranes are lifting tools that can pose a danger to people and other equipment during operation, so precautions must be taken。

The first precaution is to avoid standing under an object when lifting it。A failure of the wire rope or when lifting an object can easily result in personal injury。In addition, the lifting object should not be overexerted to avoid damage。In order to prevent the object from tilting or falling, it must be fixed firmly。The third point is that there should be no obstacles in the path of the suspended object, because obstacles may cause harm to equipment and personnel。

The harm in the air compressor room - overpressure rupture

The compressor is a supercharger, and the gas storage tank is a large pressure vessel。Such containers have a certain probability of bursting under high pressure。Although there was no such explosion at the air compressor station where I worked, a compressor in a neighboring plant exploded and blew up the entire piping system。

Many people are not fully aware of the dangers posed by compressor gas pressure。Common compressor pressure is 8kg, 10kg, 12.5kg, 14kg, etc。These values may not sound very large, nor are the units very large, but for the average person, lifting 50 kilograms is not that difficult。Moreover, the air itself does not burn or explode, so the damage caused by such pressure is limited。However, we cannot ignore it。

The "kilogram" commonly used in our industry is actually a unit of pressure equal to about 0.1 megapascal (MPa)。In other words, a 1 kilogram object placed on 1 square centimeter exerts a pressure equivalent to the size of a fingernail。When 10 kilograms of pressure is applied to the nail, it is equivalent to putting 10 kilograms of objects on it。If the air blows directly into the eyes, ears and other vulnerable parts of the human body, it may cause serious damage。Even more dangerous, a sudden explosion of a gas storage tank or a shock wave of air in a pipe can send sharp objects such as screwdrivers, wrenches, pieces of stainless steel flying out, injuring people or other equipment。That's one possibility。

There are two ways to prevent an overpressure explosion。First of all, it is necessary to ensure that the safety valve is effective and inspected regularly。Only when the safety valve is working properly, can the pressure in the high-pressure vessel be released in time to reduce the potential threat to the compressed air system。Secondly, high pressure should be prevented。If the gas consumption of the production equipment is low, the gas may become trapped in the pipeline, resulting in an increase in pressure throughout the pipe network system。If not checked in time, this high pressure situation may exist for a long time。If the stress is very high, you need to find a way to reduce the stress level by turning off the equipment。

The harm in the air compressor room - electric shock

Compressors in factories are basically devices driven by electricity, which are not only densely wired, but also carry high voltage and high current。However, electricity is invisible and can not be touched, and leakage will occur unconsciously。

The main measures to prevent electric shock accidents include the following points。First, after a power outage, switches or operating parts need to be marked or locked to ensure that the equipment can operate normally and be maintained。In addition, it is necessary to wear insulating gloves when carrying out live work to protect yourself from the current。
