What are some common mistakes to avoid when releasing pressure from a paint can?

1. Not completely shutting off the compressed air supply: Before releasing pressure, the compressed air supply connected to the paint can must be shut off. Otherwise, residual pressure may cause accidental splashing or equipment damage.

2. Ignoring the pressure regulating valve release procedure: Residual pressure in the system must be released gradually using a pressure reducing valve or pressure regulating valve. Directly disassembling parts (such as the air cap) may cause danger due to sudden pressure release.

3. Unsafe operating environment: When releasing pressure, ensure good ventilation and avoid operating in confined spaces to prevent the accumulation of harmful gases. Keep away from fire sources, as paint vapor is flammable.

4. Insufficient personal protective equipment: Not wearing protective equipment such as goggles and gloves may cause paint or splashes during pressure release to injure the skin or eyes.

5. Improper handling of the pressure can: For pressure spray guns, loosen the air cap 2-3 turns and cover it with a cloth before pulling the trigger to return the paint. Direct, forceful disassembly may cause splashing or damage to sealing components.

6. Insufficient settling time: If the paint can is not allowed to settle for a sufficient period (e.g., 3-5 minutes) after opening to allow the internal pressure to naturally equalize, paint may spray out or the can may deform.

7. Improper storage: After releasing the pressure, if the paint can is not stored in a cool, dry place, or near a heat source or direct sunlight, the increased temperature may cause the internal pressure to become abnormal again.
