Local Exhaust Ventilation (LEV) systems are crucial for protecting workers from hazardous dust, fumes, and vapours. These systems capture contaminants at the source, preventing them from spreading throughout the workplace. But like any piece of equipment, your system requires regular LEV servicing to maintain its effectiveness. Neglecting maintenance can lead to decreased performance, increased health risks, and even regulatory non-compliance.
Our advice is that LEV servicing is undertaken on a quarterly basis. In addition, visual and qualitative checks should be carried out in between.
Below are some of the signs that your LEV system needs a check-up:
1. Visible Dust or Fume Buildup
This is perhaps the most obvious sign. If you notice dust or fumes escaping the LEV system’s capture points and accumulating in the work environment, it’s a clear indication that something is wrong. This could be due to a clogged filter, a malfunctioning fan, or damaged or blocked ductwork. This shouldn’t be ignored, visible contaminants mean your LEV system isn’t doing its job and your workers are at risk.
2. Reduced Capture Efficiency
Even if you don’t see visible dust or fumes, your LEV system’s performance might be declining. You might notice a lingering odour, or workers might report experiencing symptoms like eye irritation or respiratory problems. This could indicate a decrease in the system’s airflow or capture velocity. Regular monitoring of airflow and capture efficiency is essential to identify these issues early on. Professional LEV testing can provide accurate measurements and pinpoint areas of concern.
LEV testing provides objective data on your system’s performance and can identify issues before they become serious problems. It’s also a crucial part of demonstrating compliance with health and safety regulations (COSHH). Under HSE’s Control of Substances Hazardous to Health (COSHH) Regulations, Local Exhaust Ventilation (LEV) testing is a legal requirement in the UK. Your LEV equipment must be thoroughly examined and tested by a competent person at least every 14 months to ensure your employees are safe.
3. Unusual Noises or Vibrations
A healthy LEV system operates relatively quietly. Unusual rattling or grinding noises could indicate problems with the fan, motor, or other components. Excessive vibrations can also be a sign of loose parts or imbalances. Ignoring these noises could lead to more serious damage and costly repairs down the line. Investigate any unusual sounds promptly and schedule a service appointment.
4. Changes in Your Processes or Materials
If you’ve recently changed your manufacturing processes, introduced new materials, or altered the layout of your workspace, your LEV system may no longer be providing adequate control. Different materials generate different types and amounts of contaminants, and changes in the workspace can affect airflow patterns. It’s crucial to reassess your LEV system design whenever you make changes to your operations to ensure it continues to provide effective protection.
5. Missed Scheduled Maintenance
LEV systems should be inspected and serviced regularly and in accordance with the manufacturer’s recommendations and relevant regulations. Failing to adhere to this schedule is a major red flag. Preventative maintenance is key to identifying potential problems before they escalate and ensuring the long-term performance of your LEV system. Don’t wait for something to go wrong – schedule regular servicing to keep your system in top condition.
