• Personal Protective Equipment (PPE): Essential items include insulated gloves, boots, protective clothing, along with safety helmets and goggles to protect workers.

• Lock and Warning Signs: Equipment under maintenance must be locked and tagged with clear warning signs like “Danger, Do Not Operate” to prevent unauthorized use.

• Safety Device Inspection: Post-maintenance, equipment inspection is critical. This includes technical reviews and test runs to ensure safe operation and adherence to technical standards.

• Employee Training and Education: Continuous training is essential for safe and effective processes, teaching workers hazard recognition and proper PPE usage.

Safety preparation and equipment isolation procedures not only prevent losses but also ensure the most effective and secure operation in an industrial setting.

Cleaning Procedure for Electrical Equipment

Clean from top to bottom to prevent dust from resettling on cleaned parts. Use dry cloths or specialized cleaning solutions, avoiding water or solvents that may corrode or conduct electricity. Thoroughly clean each corner, narrow gap, contact point, and dust-collecting component, using controlled compressed air to blow out deep-seated dirt. This meticulous and precise process is crucial for preserving the functionality and lifespan of factory electrical equipment.

1. Safety Preparation Before Cleaning

1. Isolate Electrical Equipment: Completely disconnect from power, ensure there is no voltage. Make sure no indicator lights are on, and no current passes through the equipment before starting the cleaning.
2. Equip with Personal Protective Equipment (PPE): Wear anti-static gloves to prevent transferring oil or dirt from hands onto equipment, and use safety goggles when necessary, especially in industrial settings.
3. Prepare cleaning tools: clean, lint-free cloths, anti-static cleaning solutions, or specialized cleaning agents for electronics, and dry, dust-free wipes.

2. Cleaning Materials and Chemicals

• Soft, Clean Cloths: Use soft, lint-free cloths to prevent scratching surfaces.
• Anti-Static Cleaning Solutions: Employ non-corrosive solutions that evaporate quickly, like NWK-99, which effectively cleans dust, light oils, and oxidation while being environmentally friendly and reducing electrical panel heat.
• Simple Homemade Solutions: A warm water-vinegar mix (1:1 ratio) or mild soapy water can clean equipment exteriors, ensuring no electronic components get wet.

3. Electrical Equipment Cleaning Procedure

1. Step 1: Ready Cloths and Solutions
   Use clean cloths lightly moistened with suitable solutions, avoiding overly wet towels that might damage electronics.
2. Step 2: Execute Cleaning
   • Gently wipe device surfaces with soft cloths to remove dust, grease, and other contaminants.
   • For circuit boards and electronic components, utilize specialized cleaning sprays to clean without dismantling parts.
3. Step 3: Re-inspect Equipment
   Ensure thorough cleaning, no residue, and dry equipment before reconnecting the power.

4. Important Considerations

• Do not clean while the equipment is powered to avoid electrical shock or fire risks.
• Avoid strong, flammable, or corrosive solvents that may damage components.
• For large machinery such as washers or air conditioners, removable parts should be cleaned more thoroughly inside to prevent damage from dirt and rust.
• Do not spray cleaning solutions directly on PCBs; instead, spray onto cloths or use sprays at a safe distance to prevent liquid accumulation in devices.

Post-Cleaning Inspection and Maintenance

After cleaning, inspect all equipment thoroughly for any damage or loose connections. Lubricate bearings and rotating shafts if the electrical equipment includes mechanical components. Test run the device to assure normal operation before resuming use. Post-cleaning inspections not only guarantee safety but also maintain optimal operation of electrical equipment.

1. Operational Inspection After Cleaning: Initially, check the operations post-cleaning by starting up the equipment. This ensures no components are damaged or loose, and detects any strange noises, unusual vibrations, or leaks.
2. Component and Part Inspection: Post-cleaning inspection of easily worn parts such as filters, RO membranes, rotors, bearings, capacitors, and motors is vital. Assess wear and plan maintenance or replacements as needed for optimal performance.
3. Lubrication: Lubricating mechanical parts like rotating shafts and gears is crucial to reduce friction and wear, extending the equipment’s life.
4. Finalize Cleaning of Outer Details and Gaps: Recheck gaps and surfaces to remove any lingering dust or residue, ensuring a final polishing of the equipment.
