The What & Why of LEV?

What is local exhaust ventilation testing (LEV testing)?

According to the HSE’s Occupational Lung Disease report for Great Britain 2017, 12,000 lung disease deaths each year are estimated to be linked to past exposures at work. This has led to understandably stringent guidelines and statutory requirements for Local Exhaust Ventilation (LEV) to prevent later life illnesses.

HSE published the third edition of HSG258 ‘Controlling airborne contaminants at work: A guide to local exhaust ventilation (LEV)’ in 2017. This guide provides guidance on the design of new local exhaust ventilation (LEV) equipment. It describes the principles of deciding on, designing, commissioning and testing effective LEV. Take a read if you are considering implementing a new LEV system at your facility.

 

Why Does LEV Need 14 month tests?

COSHH regulations require most LEV systems to be thoroughly tested at least once every 14 months, depending on usage some systems may require an earlier test than 14 months.

This applies to all oil mist, welding fume, smoke and dust extraction units that you currently have on site. This examination must be undertaken by a competent person and the tests and reports must conform to HSE standards. The HSG258 document above provides the recommended procedures to achieve these statutory requirements.

What's in a LEV Report?

Professional Analysis and Testing

Ultriamx can provide comprehensive LEV Testing for all makes and types of extraction equipment, working strictly in accordance with HSG258l guidelines. Our LEV Testing Kit include measuring the air flow speed (velocity) of the air being extracted at the source and in the ducting.

The results are compared with the requirements specified in the original system design and our expert analysis, based on years’ experience in the manufacture and design of LEV systems, allows us to provide practical advice and recommendations.

Our LEV reports include photos and/or schematic diagrams showing the Test Points, which are also clearly identified on the ducting, as required by the HSE.

LEV Testing is a legal requirement for compliance with health and safety standards and test reports often form part of a company's insurance. Inadequate testing can result in employers being prosecuted, insurance being invalidated and employees falling ill.

FAQ's about LEV Testing / Local Exhaust Ventilation Testing

Buying or improving a spray and drying facility can be a complex decision for any company. Once it's up and running the last thing you need is it shutting down by the HSE! Check out the most asked questions about LEV to keep you compliant.

Q: How much airflow/air pressure does a centrifugal spray booth need?

A: Airflow in a centrifugal spray booth is a vital safety requirement set in place to reduce the concentration of flammable material and particulate in a booth. Airflow is measured in linear feet per minute (LFM) – a measure that’s usually calculated first in an empty booth, with a cross-sectioned area of the airflow direction. According to the International Fire Code (IFC), a spray booth needs 100 linear feet per minute to meet minimum requirements.

Q: How often should local exhaust ventilation be checked?

A: LEV Testing should be conducted every 14 months to ensure that systems are functioning properly and to identify any potential problems.

Q: How do you measure local exhaust ventilation?

A: Local exhaust ventilation is measured by a number of factors. These include:•Duct velocity•Face velocity•Capture velocity•Performance, or horsepower, of the booth fan

Q: What are the limitations of local exhaust ventilation?

A: There are two primary limitations to implementing local exhaust ventilation:•Maintenance – the system requires regular cleaning, inspection and upkeep•Cost – the system may require a large capital investment up front to pay for design, installation and implementation

Q: What are the factors that reduce the efficiency of a local exhaust ventilation (LEV) system?

A: These are the most common factors affecting the efficiency of a LEV system:•Poor design•Lack of regular and planned testing•Neglect and lack of maintenance•Damaged or blocked ducting and filters•Unauthorised system changes•Incorrect system calibrations•Faults in the fan or vents

Q: Why is it so important for companies to ensure their LEV systems are tested by a competent person at least once every 14 months?

A: Control of Substances Hazardous to Health (COSHH) regulations state this is a legal requirement, however testing frequency varies depending on the application – some applications require testing as often as once a month. Full details can be found on page 85 of HSG258 ‘Controlling airborne contaminants at work A guide to local exhaust ventilation (LEV). The Health and Safety Executive (HSE) has extensive powers – it can prosecute companies if they fail to comply with improvement orders which can result in hefty fines. From a responsible employer’s point of view, it is common sense. The financial outlay of regular testing is minimal when compared to the fines that can be incurred through a HSE prosecution.

Q: What is a LEV (Local Exhaust Ventilation) System?

A: Local Exhaust Ventilation (LEV) systems capture, contain and treat air contaminated with oil mist, fume, smoke and dust at source before it has an opportunity to escape into the wider working environment. LEV systems include a hood (or multiple hoods), ducting, a filter, a fan and a discharge mechanism.

Q: Do employers need to be doing everything they can to provide a safe and clean working environment?

A: Employers have a legal responsibility under the Health and Safety at Work etc Act 1974 as follows:(1) It shall be the duty of every employer to ensure, so far as is reasonably practicable, the health, safety and welfare at work of all his employees.(2) Without prejudice to the generality of an employer’s duty under the preceding subsection, the matters to which that duty extends include in particular—(a) the provision and maintenance of plant and systems of work that are, so far as is reasonably practicable, safe and without risks to health;In addition to fulfilling legal requirements, ensuring a clean, safe workplace also has a number of other benefits:It can help to attract and retain employeesHelp to lower cleaning billsReduce hazards associated with a build-up of airborne particles such as dust and oil mist particlesIncrease productivity by reducing days lost to worker ill-healthHelp to maintain product quality

Q: Why is it important for LEV systems to be tested regularly?

A: Regular airflow readings can identify any problems with the system’s performance. Blocked or saturated filters, or damaged ducting can impact on the extraction capability - meaning the system is less able to cope with the volume of air which needs cleaning. The test records the current reading as well as results from previous tests, or the original design requirement. The inspector can cross reference all of the data to ensure the system is operating as intended.

Q: What does a HSE compliant LEV test report look like?

A: The reports that Filtermist issues are legal documents which consist of the following:Full company details and date of testDetails of the substance/process being controlledA photo of the LEV system being tested or a schematic drawingTest data including water gauge static pressure, velocity in m/sec and volume flow rateReadings from all extraction pointsImprovement recommendationsPass / failInspector’s statement of competencySafety policyMethod statementRisk assessmentReport observationsDetails of next recommended visitNB: It’s important to remember that if HSE asks for a copy of the report, you must supply the whole document – not just the sheet with the test results as it won’t mean anything without the rest of the report.

Q: How long does a LEV test take to carry out ?

A: The length of time it takes to carry out an LEV Test varies depending on factors including the accessibility of the system, and the type of installation it is. The first visit is always the longest as the our appointed engineer will complete a risk assessment form, take photos of the systems that need testing and record all of the other details needed for the report. If nothing has changed in terms of the system set-up, the time it takes to carry out subsequent tests dramatically decreases.

Q: Why is it so important for anyone with an LEV system to have them regularly tested?

A: Regular LEV Testing is crucial for two reasons:1. To protect employees from the health risks associated with exposure to airborne contaminants2. To protect employers from HSE prosecution.
