Local Exhaust Ventilation (LEV) systems play a critical role in maintaining a safe and healthy workplace, especially in environments where harmful airborne substances are a concern. However, ensuring this level of protection doesn’t just happen by itself—it demands consistent care and maintenance.
Think of an LEV system like a car. To keep your vehicle running smoothly and safely, regular servicing is essential. The same principle applies to your machinery; without proper upkeep, it simply can’t perform its vital role effectively.
So, what does it take to keep your LEV systems in top condition?
To help you, we’ve put together a detailed guide. By following these steps, you’ll ensure your system operates efficiently while meeting workplace safety standards.
LEV System Maintenance: Steps to Follow
1. Conduct Regular Visual Inspections
Regular visual inspections are the first line of defence. These inspections should focus on checking the integrity of system components, such as ducts, hoods, and filters, for any signs of wear, blockages, or physical damage.
Look for loose connections, corrosion, or any visible build-up of dust or debris that could hinder the system’s performance. By conducting these routine checks, you can identify minor issues before they escalate into costly repairs or failures.
Just as you might glance at your car’s dashboard for warning lights, visual inspections of your LEV system can reveal early warning signs that maintenance is needed. Ideally, these checks should be carried out weekly or monthly.
2. Test Airflow Performance
Testing airflow performance is crucial. This involves measuring the system’s ability to effectively capture and contain airborne contaminants. Tools such as anemometers or manometers will help you ensure that the equipment is operating within the parameters necessary to protect workers from harmful exposure.
It is recommended to perform airflow tests annually or whenever there is a noticeable drop in system performance. These tests identify potential issues and ensure compliance with health and safety regulations. Insufficient airflow is indicative of blockages, leaks, or worn-out components that require immediate attention.
3. Clean System Components
Over time, ducts, hoods, and filters can accumulate dust, debris, and other contaminants, which can significantly reduce performance and increase energy consumption. Regular cleaning prevents build-up that might block airflow or impair extraction.
Pay particular attention to clogged filters, as they can strain the system and decrease its effectiveness. Depending on the intensity of use and the type of substances being extracted, cleaning schedules may vary, but it’s generally recommended to clean components every 3-6 months. In environments with heavy use, more frequent cleaning may be required.
4. Verify Control Panel Functionality
The control panel acts as the system’s command centre, managing airflow rates, filter monitoring, and overall performance. That’s why it’s paramount to regularly check for any error messages or warning lights on the panel.
Test all controls and switches to confirm they are responsive and accurately reflect the system’s status. Faulty control panels can lead to improper operation, increasing health risks and reducing efficiency.
Just as you wouldn’t ignore a flashing ‘check-engine’ light in your car, addressing control panel issues promptly can prevent larger, costlier problems down the line.
5. Conduct a Thorough Annual Service
An annual service is the most comprehensive step in maintaining your LEV system. This process involves a detailed inspection and professional testing of all components to ensure the equipment meets safety and performance standards. Certified technicians typically evaluate airflow rates, check for blockages, inspect for wear and tear, and assess filter and fan efficiency.
It is important to remember that, in the UK, the Control of Substances Hazardous to Health (COSHH) Regulations 2002 require that Local Exhaust Ventilation systems are thoroughly examined and tested at least once every 14 months. This is the minimum legal standard to ensure everything is functioning effectively and protecting workers from hazardous substances.
6. Maintain Documentation
Keeping detailed records of all inspections, repairs, and services ensures you have a comprehensive history of the system’s performance and any actions taken.
These records help track trends or recurring issues and also demonstrate compliance with health and safety regulations during audits. Detailed documentation can save time, provide valuable insights, and ensure your system remains reliable over the long term.
7. Plan for Upgrades
Planning for upgrades is essential to ensure that your equipment stays ahead of technological advancements and meets evolving workplace requirements.
As industries grow and regulations change, older systems may struggle to keep up with the demands of modern safety and efficiency standards.
Begin by assessing your current system’s performance and identifying areas where improvements could be made. For example, newer technologies may offer enhanced filtration, energy efficiency, or monitoring capabilities that reduce costs and improve overall functionality.
Moreover, regularly consulting with LEV specialists can help you stay informed about innovative solutions and determine the best time to invest in upgrades. Think of this step as upgrading your car with the latest features to boost performance and safety—it’s an investment that pays off in reliability and peace of mind.
8. Train Your Team
A well-trained team is the backbone of an effectively maintained operation. Employees should be educated on the importance of the system, how it works, and their role in its upkeep. Training should cover performing basic maintenance tasks, identifying warning signs of potential issues, and reporting concerns promptly.
Additionally, ensure that workers understand the health and safety risks associated with poorly functioning LEV systems. Empower them to conduct visual checks and adhere to proper procedures for cleaning or operating the equipment.
For more technical maintenance or adjustments, designate specific team members to receive advanced training or certifications from specialists.
Furthermore, regular refresher courses and updates are vital, especially when upgrades or new features are added to the system.
