LEV Testing refers to Local Exhaust Ventilation Testing, a process used to evaluate the effectiveness of ventilation systems designed to capture and remove hazardous substances from the air in workplaces. The goal of LEV systems is to protect workers from exposure to airborne contaminants, such as dust, fumes, gases, and vapors, by capturing them at the source before they can spread through the air.
Purpose of LEV Testing
–Protect worker health: LEV systems are designed to reduce exposure to hazardous substances, minimizing health risks like respiratory issues, chemical burns, or long-term diseases like cancer.
–Ensure compliance: LEV testing helps ensure that the ventilation system meets regulatory standards and that employers comply with occupational health and safety laws.
–Maintain effectiveness: Regular testing ensures that the LEV system is operating at optimal efficiency, preventing the build-up of harmful substances in the workplace.
Key Components Tested
–Capture Velocity: The speed at which air is drawn into the exhaust system, important for ensuring that contaminants are effectively captured at their source.
–Airflow Rate: The volume of air passing through the system, measured in cubic feet per minute (CFM), to ensure sufficient ventilation.
–Face Velocity: The speed of the air at the point where the hood or extraction system meets the contaminant source.
–Hood Design: The design of the hood, canopy, or other capture points that directly interact with the contaminants, ensuring they are positioned correctly to capture airborne particles.
–Ducting and System Integrity: Ensures there are no leaks, blockages, or other issues in the ductwork or system components that would reduce efficiency.
Frequency of Testing
LEV systems should be tested regularly to ensure continuous performance. Regulations require4 LEV Systems to be tested at least once every 14 Months, we can remove the hassle of remembering when your last test was by Scheduling a test and reminders at your chosen intervals, commonly 12 months of 14 months.
Regulations and Standards
LEV systems must comply with various health and safety regulations, which may differ by country. For example:
In the UK, HSE (Health and Safety Executive) guidelines outline the responsibilities of employers to ensure adequate ventilation and perform regular testing.
Benefits of LEV Testing
–Health and Safety Compliance: Helps businesses meet safety regulations and avoid penalties.
–Increased Worker Productivity: Proper ventilation creates a safer and more comfortable working environment, which can improve morale and productivity.
–Cost Savings: Regular testing can help detect issues early before they become costly to repair and maintain, avoiding larger, more expensive breakdowns or legal issues.
