What is LEV Servicing and Why is it Important?

About

Local Exhaust Ventilation (LEV) systems play a crucial role in maintaining a safe and healthy work environment, especially in industries where airborne contaminants are a concern. LEV systems are designed to capture, contain, and control hazardous substances at their source, preventing them from spreading into the workplace. Regular LEV servicing is essential to ensure these systems operate effectively and comply with health and safety regulations. This guide explores the importance of LEV servicing, what it entails, and its benefits.

The Importance of LEV Servicing

1. Health and Safety Compliance: The Health and Safety Executive (HSE) in the UK mandates that LEV systems must be regularly inspected and maintained. This ensures they provide adequate protection against hazardous substances such as dust, fumes, vapors, and gases. Failure to comply with these regulations can result in significant fines and legal action.
2. Efficient Operation: Regular servicing ensures that LEV systems function efficiently. Over time, filters can become clogged, ducts can accumulate debris, and fans may wear out. Servicing helps identify and rectify these issues, ensuring the system operates at peak performance.
3. Cost Savings: Preventive maintenance can save significant costs in the long run. Addressing minor issues before they escalate into major problems reduces the risk of system breakdowns, which can be costly to repair and lead to production downtime.
4. Prolonged Equipment Life: Regular servicing and maintenance can extend the lifespan of an LEV system. Proper care and timely replacement of worn-out components prevent premature failure and ensure the system remains effective for years.

What LEV Servicing Entails

1. Visual Inspection: A thorough visual inspection of the entire LEV system is conducted to identify any obvious signs of wear and tear, damage, or blockages. This includes checking hoods, ducts, filters, and extraction points.
2. Performance Testing: Various tests are performed to assess the system’s performance. This includes measuring airflow rates, static pressure, and capture velocity. These tests ensure that the system is effectively capturing and containing contaminants.
3. Filter Checks and Replacements: Filters play a crucial role in trapping harmful particles. During servicing, filters are checked for clogging and damage. If necessary, they are cleaned or replaced to ensure optimal filtration.
4. Fan and Motor Maintenance: The fan and motor are critical components of an LEV system. They are inspected for any signs of wear, and their performance is tested. Lubrication, cleaning, and adjustments are made as needed to maintain efficient operation.
5. Ductwork Cleaning: Over time, ducts can accumulate dust and debris, which can obstruct airflow and reduce system efficiency. Regular cleaning of ductwork is essential to maintain optimal performance.
6. System Balancing and Adjustments: Based on the test results, adjustments may be made to balance the system and optimize airflow. This ensures that contaminants are effectively captured at their source.
7. Documentation and Reporting: Detailed records of the servicing, including test results and any maintenance performed, are documented. This ensures compliance with regulatory requirements and provides a history of the system’s maintenance.

Benefits of Regular LEV Servicing

• Enhanced Workplace Safety: Regular servicing ensures that LEV systems effectively capture and control hazardous substances, protecting workers from exposure to harmful contaminants.
• Regulatory Compliance: Adhering to servicing schedules and maintaining detailed records helps businesses comply with health and safety regulations, avoiding fines and legal issues.
• Increased Efficiency: Well-maintained LEV systems operate more efficiently, reducing energy consumption and operational costs.
• Reduced Downtime: Preventive maintenance minimizes the risk of unexpected system failures, reducing production downtime and associated costs.
• Long-term Savings: Regular servicing extends the lifespan of the LEV system, reducing the need for costly replacements and repairs.

Conclusion

In conclusion, LEV servicing is a vital aspect of maintaining a safe, efficient, and compliant workplace. By ensuring regular maintenance and servicing of LEV systems, businesses can protect their workforce, comply with regulations, and achieve long-term cost savings. Whether through in-house maintenance teams or professional servicing companies, it is essential to prioritize the regular upkeep of LEV systems to ensure their continued effectiveness.
