Understanding LEV COSHH Testing: Safeguarding Workplace Health and Safety


In workplaces where hazardous substances are handled, ensuring the health and safety of employees is paramount. Exposure to harmful chemicals and dust can pose significant risks to workers' health if not properly managed. Local Exhaust Ventilation (LEV) systems and Control of Substances Hazardous to Health (COSHH) testing play a crucial role in maintaining a safe working environment.


Not sure what LEV is?

LEV systems remove harmful substances at the source, preventing inhalation by workers. They include hoods, ducts, cleaners, and fans. Check out our blog on "Dust, Fume and Vapour Extraction - capturing airborne particles at-source."



What is the importance of LEV COSHH testing?

The Control of Substances Hazardous to Health (COSHH) regulations are enforced by the UK's Health & Safety Executives. They require employers to control exposure to hazardous substances to prevent ill health. COSHH testing ensures that the LEV systems work effectively and maintain exposure levels below permissible limits.



Understanding LEV COSHH Testing

LEV COSHH testing involves a comprehensive assessment of the performance of LEV systems to ensure they adequately control hazardous substances. The testing process typically includes several key steps:


1. Initial Assessment: A thorough examination of the LEV system's design, installation, and operation is conducted to identify potential issues or deficiencies.


2. Measurement of Airflow Rates: Airflow rates at various points within the LEV system are measured to ensure adequate air volume is extracted to control the hazardous substances effectively.


3. Capture Velocity Testing: This test assesses whether the LEV system effectively captures contaminants at the source by measuring the air velocity near the extraction hood.


4. Examination of Ductwork and Filters: The condition of ductwork, filters, and other components of the LEV system is inspected to identify any damage, blockages, or signs of wear that may affect its performance.


5. Smoke Visualisation Testing: Smoke is introduced into the LEV system to visually assess airflow patterns and identify any stagnation or inadequate capture areas.


6. Documentation and Reporting: Detailed testing procedures, measurements, and findings are documented to provide a clear overview of the LEV system's performance and any remedial actions required.



Benefits of LEV COSHH Testing


1. Worker Safety: By ensuring that hazardous substances are effectively controlled, LEV COSHH testing helps protect the health and safety of workers, reducing the risk of occupational illnesses and respiratory conditions.


2. Legal Compliance: Compliance with COSHH regulations is essential for employers to avoid legal repercussions and ensure a safe working environment for their employees.


3. Cost Savings: Early detection of LEV system issues through regular testing can prevent costly repairs, downtime, and potential fines resulting from non-compliance.


4. Improved Productivity: A safe and healthy working environment increases employee morale, productivity, and retention.



Conclusion

In conclusion, LEV COSHH testing is vital to occupational health and safety management in workplaces with hazardous substances. By ensuring that LEV systems are effectively controlling exposure to harmful chemicals and dust, employers can safeguard the health and well-being of their employees while maintaining legal compliance and promoting a productive work environment. Regular testing, maintenance, and ongoing monitoring of LEV systems are essential to mitigate risks and uphold the highest workplace safety standards.
