Maintenance and inspection in explosive atmospheres are essential to ensure the safety and integrity of equipment and systems in classified areas
Maintenance and inspection in explosive atmospheres are essential to ensure the safety and integrity of equipment and systems in classified areas, where the presence of flammable or combustible substances can create explosion hazards.
Here are some procedures and protocols that can be followed to ensure the integrity of these equipment and systems.
- Identification of classified areas: The first step is to identify the classified areas according to local standards and regulations, such as the ABNT NBR IEC 60079 standard (or equivalent in your country). This identification will help determine which equipment and systems are subject to explosion risks.
- Maintenance and Inspection Plan: Develop a specific maintenance and inspection plan for the equipment and systems in classified areas. This plan should include the activities to be performed, the frequency of inspections, the testing and inspection techniques to be used, and the responsibilities of the teams involved.
- Qualified team: Ensure that the team responsible for maintenance and inspection is properly qualified and trained to work in classified areas. They should have knowledge of safety requirements, appropriate testing and inspection techniques, and emergency procedures.
- Visual inspection: Perform regular visual inspections of equipment in classified areas to identify signs of wear, damage, or abnormal conditions. Check for leaks, corrosion, loose or damaged wiring, dirt buildup, or any other condition that may compromise safety.
- Testing and measurements: Perform periodic tests and measurements on equipment, such as grounding resistance measurement, cable integrity verification, explosion protection system operation tests, among others. These tests help ensure that the equipment is in compliance with safety requirements.
- Preventive maintenance: Implement a preventive maintenance program based on manufacturer recommendations and regulatory requirements. This may include lubrication, replacement of worn parts, adjustments, cleaning, and other procedures aimed at keeping the equipment in good operating condition.
- Recording and documentation: Keep detailed records of all maintenance and inspection activities carried out in classified areas. This includes dates, description of activities performed, test and measurement results, replaced parts, and other relevant information. These records help document compliance with regulatory requirements and track the maintenance history.
- Training and awareness: Conduct regular training for the team responsible for maintenance and inspection in classified areas. This includes safety training, knowledge of applicable standards and regulations, and awareness of the risks associated with explosive atmospheres.
