What is LEV Testing?

In the varied landscape of industrial safety, Local Exhaust Ventilation (LEV) testing emerges as a fundamental requirement, one mandated by law across the United Kingdom. LEV systems are engineered to protect workers from the hazardous effects of airborne contaminants such as dust, fumes, and vapour. To safeguard their efficiency and reliability, testing, also known as thorough examination and testing (TExT), is imperative. In this article, we will delve into the specifics of LEV testing, its significance, and the stringent standards that govern it.

Understanding Local Exhaust Ventilation Systems

Before exploring LEV testing, it's essential to understand the role of Local Exhaust Ventilation systems. LEVs are designed to capture and remove contaminants at the point of generation before they disperse into the workplace air. They are critical components in industrial settings, workshops, and factories, where they help maintain clean air, thus ensuring a safer environment for workers.

The Importance of Regular LEV Testing

The efficiency of an LEV system is not solely determined at its installation but through its entire operational lifespan. Regular LEV testing is fundamental to ensure these systems are functioning optimally. Beyond the evident health benefits of maintaining clean air, regular testing assures compliance with Health and Safety Executive (HSE) regulations. In the UK, the HSE requires LEV systems to be thoroughly examined and tested at least every 14 months.

Key Components of LEV Testing

LEV testing involves a comprehensive examination of various components of the system including the hood, ductwork, filters, and fans. This examination ensures that each part is in good working order. The process includes:

• Visual inspections to detect any observable signs of wear, damage, or alterations.
• Measurement of technical performance to assess whether the system is working to its designed capacity.
• Examination of controls, gauges, and alarms for proper function.
• Assessment of the workforce exposure level to verify that it is below the Workplace Exposure Limits (WELs) set by the HSE.

LEV testing must be conducted by competent persons—those who have the necessary skills, knowledge, and experience to undertake the task.

Compliance with Health and Safety Regulations

Health and safety regulation in the UK is robust and requires employers to not only install effective LEV systems but to also maintain them in good working order through regular testing. The Control of Substances Hazardous to Health (COSHH) Regulations require that control equipment such as LEV systems are properly maintained and tested. Non-compliance can result in severe fines and legal action, not to mention the potential health risks posed to employees.

Selecting a Provider for Your LEV Testing Needs

When considering LEV testing for your industrial environment, choosing a provider like WBT Services Ltd, which operates across the UK, is critical. They offer the expertise needed to conduct LEV testing to the highest standards.

A comprehensive LEV test from a reputable provider should result in the production of a detailed report that outlines the testing conducted, the findings, and any recommendations for action to ensure the system's continued effectiveness.

The Technical Accuracy of LEV Testing

The technical accuracy of LEV testing cannot be understated. A misdiagnosis or incomplete assessment can lead to false complacency or unnecessary overhauls of systems. That is why LEV tests are more than a cursory review; they involve meticulously looking into the system's capacity to continue its task of safeguarding the environment against hazardous substances.

Experts will evaluate airflow readings and pressure measurements against the designed performance criteria. In addition, they will look into whether the system's capture velocity is sufficient to control the contaminants. A technically thorough test will account for changes in processes or workplace layouts that might impact the system's operation.

Keeping Up with Advancements and Best Practices

The industry does not stand still, and as advancements are made in technology and processes, the best practices for Local Exhaust Ventilation and their testing continue to evolve. Professionals engaged in LEV testing keep abreast of these changes, ensuring that the service they provide reflects the latest guidance and regulations.
