What are the safety precautions during the operation of the spray gun kits?

Familiarize yourself with the equipment instructions and conduct a preliminary inspection
Before you start using the airbrush kit, you should carefully read the instruction manual and safety manual provided with the equipment. Understanding the connection methods, air pressure range, flow adjustment methods and other information of each component will help the stability and safety of subsequent operations. Before use, the airbrush body, nozzle, hose, joints and air compressor should be fully inspected to confirm that there are no leaks, cracks, looseness, etc. to avoid malfunctions during operation.

Reasonably configure the air source pressure and check the stability
airbrush kits usually rely on compressed air as a power source. If the air source pressure is set unreasonably, it may cause the airbrush to rebound, spray abnormally or damage the pneumatic components. When using, the recommended working pressure (such as 2.5–4.5 bar) should be set according to the airbrush parameters, and a pressure gauge should be installed for monitoring. At the same time, ensure that the air pipe is firmly connected and there is no folding or leakage. If the air source fluctuates violently, the operation should be suspended and the cause should be checked to prevent the abnormal air pressure from causing the airbrush to run out of control.

Wear appropriate protective equipment
During the operation, the airbrush releases fine atomized particles or vapors, which may irritate the respiratory system, skin and eyes. Operators should wear protective equipment such as protective masks, protective glasses, protective gloves and work clothes that meet the standards. When operating in a closed or poorly ventilated environment, local ventilation devices should be configured or respirators with filter systems should be worn to reduce the risk of inhalation of harmful substances.

It is prohibited to use flammable spray media in open flames or high temperature environments
Many airbrush kits are used to spray paints, solvents, cleaning agents and other liquids with certain volatility and flammability. During operation, stay away from open flames, electric sparks, high-temperature equipment and smoking areas. The spraying site should be marked with "No Fire" signs and equipped with emergency equipment such as fire extinguishers. Once the ambient temperature is too high, the vapor concentration of the sprayed liquid may reach a dangerous level, increasing the risk of combustion and explosion, which must be taken seriously.

Keep the work area well ventilated
During the use of the airbrush, some materials will form suspended particles, mist residues or organic gases after spraying. If operated in a closed environment for a long time, it may affect the health of the operator. Therefore, spraying operations should be carried out in well-ventilated areas as much as possible, or auxiliary equipment such as industrial exhaust fans and exhaust hoods should be installed for local exhaust, and harmful gases should be discharged outdoors in time to reduce the risk of concentration accumulation.

Spraying direction should avoid contact with people and electrical equipment
The aerosol released by the airbrush nozzle has a certain impact force and diffusion range. When using, the nozzle should be aimed at the surface of the workpiece, and should not be operated towards people, electrical equipment or other vulnerable equipment. Especially when adjusting the nozzle, cleaning the airbrush or replacing the container, make sure to turn off the gas source to avoid accidentally triggering the airbrush switch to prevent accidental injury to others or damage to the equipment.

Avoid frequent disassembly or replacement of parts during operation
During the operation of the airbrush, the nozzle, needle valve and other parts are under high pressure and should not be forcibly disassembled or adjusted without pressure relief. If abnormal spraying or unstable flow is found, the gas source should be turned off and the residual pressure should be emptied before cleaning or replacement. Avoid frequent disassembly and assembly of connectors during operation to reduce seal wear, thread damage and air leakage.

The equipment should be cleaned and stored in time after stopping
After using the airbrush, it should be cleaned immediately to avoid condensation and blockage of paint or liquid in the nozzle and channel. The cleaning fluid should be compatible with the spray medium and operated correctly according to the instructions. After the airbrush is cleaned, it should be stored in a dry and light-proof place to prevent dust from entering the spray hole or moisture from causing rust. A small amount of dry gas can be filled into the interior before storage to protect the components and extend the life of the equipment.

Regular maintenance and fault detection
The airbrush kit is a high-frequency tool, and a regular maintenance system should be established. Check the aging of the air pipe, whether the sealing ring is deformed, whether the nozzle is worn, and whether there is dirt inside. Once the spray volume is reduced, the atomization is uneven or leaking, the damaged parts should be repaired or replaced in time. In places with conditions, a regular pressure test and spray quality inspection mechanism should be established to ensure that the equipment is in good condition.

Strengthen operation training and safety awareness publicity
airbrush operation involves certain technical requirements and safety knowledge. Enterprises or individual users should provide necessary technical training for operators. The training content should cover the equipment structure principle, operating procedures, safety risk identification and emergency response process. New employees or non-professionals should not operate the airbrush independently. The safety awareness of all personnel can be improved through a combination of graphic manuals, safety signs and on-site explanations.
