Local Exhaust Ventilation (LEV) systems are designed to control and remove airborne contaminants from a workplace, protecting workers' health and ensuring compliance with health and safety regulations. However, to ensure their effectiveness, these systems need to be regularly inspected and maintained. In this blog, we'll discuss the importance of inspecting LEV systems and provide some guidance on how to do so effectively.
The inspection of LEV systems is important for several reasons. First and foremost, it ensures that the system is working effectively and efficiently, protecting workers from exposure to harmful airborne contaminants. Regular inspections can also help to identify any potential issues before they become more serious problems, reducing the risk of downtime or costly repairs.
In addition, the inspection of LEV systems is a legal requirement in many countries, with health and safety regulations mandating that employers maintain these systems in good working order. Failure to comply with these regulations can result in fines or legal action, as well as damage to your company's reputation.
When inspecting an LEV system, there are several key components you should examine to ensure that the system is working effectively. These include:
The frequency of inspections for an LEV system will depend on several factors, including the type of contaminants being captured, the frequency of use, and the environment in which the system is operating. As a general rule, LEV systems should be inspected at least once a year, although more frequent inspections may be required for systems in heavy use or in harsh environments.
In addition to regular inspections, LEV systems should also be tested periodically to ensure that they are working effectively. This can include smoke tests, tracer gas tests, or dust lamp tests, which can help to identify any leaks or issues with the system.
Inspection of local exhaust ventilation systems is essential for protecting workers' health, complying with health and safety regulations, and ensuring the system is working effectively. By examining key components such as the hood or capture device, ductwork, fan, filter or scrubber, airflow measurements, and controls, you can identify any issues with the system and take corrective action as needed. Regular inspections and testing can help to prevent downtime, reduce the risk of costly repairs, and ensure that your LEV system is protecting your workers and your business.
