6 Reasons Why LEV Testing will benefit your company
In the workplace, ensuring the health and safety of employees stands as a top priority. Moreover, maintaining high air quality to prevent exposure to hazardous substances becomes crucial. Local Exhaust Ventilation (LEV), therefore, plays a pivotal role in removing harmful airborne contaminants. This makes LEV testing an essential practice, which we will delve into further in this page. Here, we aim to explore the significance of LEV Testing, emphasizing its role in safeguarding worker well-being, complying with regulations, and creating a healthier work environment.
1) Protecting Worker Health
Industrial processes often generate airborne contaminants such as dust, fumes, and gases. Consequently, exposure to these substances can lead to severe health issues. These health issues include respiratory diseases, skin disorders, and even cancer. LEV systems, designed to capture and remove these pollutants at the source, serve as the first line of defense. Ensuring regular LEV testing is essential to guarantee these systems function as they should, thereby reducing employees’ risk of exposure and related health problems.
2) Enhanced Output
A safe and healthy work environment directly impacts employee morale and output. As a result, poor air quality can lead to discomfort, fatigue, and absenteeism. This is where properly maintained LEV systems, with regular testing, come into play. They ensure that employees work in an environment conducive to their well-being. In this context, cleaner air means fewer respiratory issues, reduced sick days, and improved concentration. Ultimately, this leads to higher output and better overall job satisfaction.
3) Long-Term Cost Savings
Although investing in LEV Systems and regular testing may incur initial expenses, it’s a prudent long-term investment. Health issues resulting from exposure to hazardous substances can lead to increased healthcare costs, worker compensation claims, and potential legal disputes. By addressing air quality through LEV Testing, companies can reduce these risks and save the costs of medical treatment and legal disputes.
4) Customized Risk Management
Every industrial setting is unique, characterized by specific processes and pollutants. Consequently, the ability to customize LEV systems to address these specific risks becomes imperative. LEV Testing offers the opportunity to tailor ventilation solutions. In doing so, it ensures that systems are optimized for capturing pollutants effectively. This highly targeted approach not only maximizes system effectiveness but also minimizes energy use.
5) Sustainability and Environmental Impact
Beyond the direct benefits to worker health, LEV systems contribute to broader sustainability goals. Effective LEV systems serve as barriers, to prevent the release of pollutants into the atmosphere. This action significantly reduces the environmental impact of industrial processes. As a result, companies can uphold their corporate social responsibility commitments and minimize their ecological footprint.
6) Compliance with Regulations
According to the COSHH regulations, employers have an obligation to prevent their workers’ exposure to hazardous substances. In cases where prevention is not reasonably practicable, they must adequately control hazards. Testing plays a pivotal role in ensuring that an LEV system functions as it was intended, safeguarding worker health, and ensuring regulatory compliance.
How often should you Test LEV Systems?
Regulation 9 requires that firms employing LEV systems must arrange tests at intervals of 14 months or fewer. As part of our service, we can notify you when your LEVs need testing, provided free of charge. Furthermore, we offer discounts for tests covering multiple visits.

Who should conduct LEV testing?
When it comes to Local Exhaust Ventilation (LEV) testing, choosing the right person or company is vital. Furthermore, LEV testing plays a crucial role in workplace safety and compliance. It demands expertise to ensure that ventilation systems effectively protect workers from hazardous airborne contaminants. Therefore, here’s who should perform an LEV test:
Qualified LEV Testing Professionals: Experienced and certified individuals specializing in occupational hygiene and ventilation are the most suitable candidates. They need the qualifications and training to comprehensively understand LEV system principles, specific equipment, and relevant regulations. Certifications like the BOHS Modules P601, P602, P603 and P604 are essential. This is because it shows that workers have gained recognition in the field of LEV testing.
Occupational Hygienists: Trained to identify and control workplace hazards, including airborne contaminants, occupational hygienists possess the knowledge and skills required. They can effectively assess LEV system effectiveness, conduct precise measurements, and ensure compliance with relevant regulations and standards.
Experienced Engineers: Engineers with expertise in industrial ventilation and LEV systems can also be qualified to conduct LEV tests. Their in-depth understanding of LEV system design, installation, operation, and maintenance, along with awareness of potential health risks associated with handled substances, makes them suitable candidates.
Certified LEV Testing Companies: Many companies specialize in providing LEV testing services. These firms often employ a team of certified professionals who possess the expertise to assess and test ventilation systems. Choosing a certified LEV testing company will assure you that experts conduct the testing.
Regular Maintenance Personnel: In certain situations, companies may have in-house maintenance personnel familiar with their LEV systems. While they may lack the same level of expertise as specialized professionals, they can conduct routine checks for obvious issues. However, it’s crucial to complement these efforts with periodic professional testing.
Certification and Accreditation: Regardless of who conducts the LEV test, it’s essential to verify their certification and accreditation in the field. Certification and accreditation serve as guarantees of their competence and adherence to industry standards.
Testing Frequency: The frequency of LEV testing can change based on several factors. Factors such as the nature of the controlled substances, usage intensity, and manufacturer recommendations. Therefore, it’s imperative to ensure that the chosen individual or entity can perform tests at the mandated intervals, which are typically at least once every 14 months.
In conclusion, the individuals responsible for carrying out LEV tests should possess the requisite qualifications, experience, and knowledge to ensure the effectiveness of the ventilation system. Prioritizing collaboration with certified professionals or reputable LEV testing companies is crucial to uphold workplace safety, safeguard employee health, and maintain regulatory compliance.
LEV testing goes beyond mere regulatory compliance; it’s a cornerstone of a secure, healthy, and compliant workplace. Regularly evaluating and maintaining LEV systems not only safeguards employees but also minimizes costs while ensuring adherence to industry standards and regulations. Embracing LEV testing reflects a commitment to both the well-being of the workforce and the sustainability of operations. Ultimately, it guarantees that every breath taken within an industrial setting is one taken with confidence, security, and good health.
