Understanding LEV Servicing Standards and Regulations

Introduction to Local Exhaust Ventilation (LEV) Systems

When you operate within an industry where employees are exposed to airborne contaminants, the role of Local Exhaust Ventilation (LEV) systems becomes critical. LEV systems are designed to protect workers by controlling the emission of hazardous substances to the air. Ensuring these systems are functioning correctly is not only a matter of maintaining a safe work environment but is also a legal requirement. In this blog post, we'll guide you through the servicing standards and regulations you must adhere to, ensuring that your LEV systems are up to par.

The Importance of Regular LEV Servicing

Regular LEV servicing is essential for the continued health and safety of your workforce. It involves professional inspection and maintenance to ensure that all components of your LEV system are operating efficiently and effectively. Neglecting these service checks can lead to potential exposure to harmful substances, which can result in health issues and non-compliance with health and safety legislation.

Benefits of Servicing Your LEV System

Understanding the Regulations

As part of your regulatory compliance, you are required to follow the guidelines set out in the Control of Substances Hazardous to Health (COSHH) regulations. These regulations dictate that LEV systems must undergo thorough examination and testing at least every 14 months. This is where professional LEV testing services come into play, ensuring your systems meet legal standards and are safe for use.

Key Components of LEV Regulations

Initial Appraisal: A comprehensive assessment of the system's design and performance capabilities.

Thorough Examination and Testing: A detailed inspection carried out by a competent person to ensure the system's effectiveness in controlling contaminants.

Maintenance and Repairs: Prompt addressing of any identified issues or malfunctions discovered during the examination.

Record Keeping: Maintaining a log of all LEV servicing, testing, and repairs for at least five years.

Choosing the Right LEV Servicing Provider

The selection of a qualified LEV servicing provider is crucial. You should look for a provider with a proven track record who understands the intricacies of LEV systems. A professional service provider will offer comprehensive assessments and give you advice tailored to your specific needs.

What to Expect from Your LEV Service

An effective LEV servicing session should include the following:

Maintaining Compliance and Performance

Maintaining compliance with LEV servicing standards and regulations ensures that your systems continue to protect workers and that your operations adhere to legal requirements. Adequate records of servicing and testing must be kept as evidence of compliance. This not only demonstrates your commitment to health and safety but also protects your business legally.

LEV Documentation and Record Keeping

Accurate and up-to-date documentation is critical for demonstrating compliance. Your LEV servicing provider should supply you with a detailed report after each service, including any recommendations for improvements or necessary repairs. This documentation forms part of your legal records and must be available for inspection by regulatory authorities.
