LEV System Repairs and Retesting Services for Failed Examinations
Premier LEV provides LEV repairs and remedial support for workplace dust and fume extraction systems, alongside examination and retesting. If your latest report records an unsatisfactory result, the first step is to understand the defects, agree the work required and decide how its effectiveness will be checked.
What to do after an unsatisfactory LEV examination
Read the report, including its limitations, and ask the examiner to explain anything unclear. Identify which equipment and processes are affected. Do not assume an operating fan means extraction is providing adequate control.
Arrange competent advice on the risks and any measures needed before continuing affected work. HSE advises that, after a failed hood or system is repaired, a competent person should check that it is effective and adequately controls exposure before the failed label is removed. See the HSE LEV FAQs.
Define the repair scope from the findings
An unsatisfactory report does not automatically mean the entire installation must be replaced. The work should address the identified defects and the process the system serves. Depending on the assessment, an enquiry may concern:
Damaged or leaking ductwork, connections and supports.
Worn, blocked or incorrectly fitted filters.
Damaged extraction hoods or unsuitable positioning.
Fan, drive or other component faults.
Changes to the process or extraction layout that need reassessment.
Premier LEV can discuss inspection, servicing, replacement parts and remedial work. Where larger alterations are appropriate, our LEV installation service provides a route to discuss the revised system. The agreed scope, access arrangements and parts availability determine the programme; a same-visit repair is not always possible.
A real example: ductwork replacement and retesting
In a laser-cutting project, the initial examination recorded ineffective fume control, leakage at several spiral-duct joints, a loose connection and poor duct supports. Filters were also incorrectly fitted. Servicing actions during the first visit did not change the overall unsatisfactory assessment.
The remedial work included replacing the spiral ductwork with clip-together ductwork and replacing poor supports. A subsequent examination, with the laser operating, recorded a satisfactory assessment. Read the full case study and see the before-and-after photographs.
This example shows why the repair scope needs to reflect the examination findings. Its outcome relates to that installation and the scope of its reports; it is not a guarantee of the result for another system.
Agree checks after the repair
Discuss the follow-up assessment when planning the work. This may include relevant measurements, inspection and observation of the process in use. Make the earlier examination and any commissioning information available so the person checking the system can assess its intended performance.
Keep the repair record and subsequent assessment together. Ask which defects have been addressed, whether any limitations remain and what maintenance or further work is recommended. A repair invoice describes work carried out; it does not by itself demonstrate effective contaminant control.
Information to send for an LEV repair enquiry
Your site location and the affected process.
The latest examination report and system identification.
Equipment make, model and photographs of accessible components.
The faults reported and changes noticed by operators.
Recent repairs, filter changes or process alterations.
Access restrictions and available working hours.
There is no single repair price for every system. Scope, replacement parts, safe access and the required follow-up assessment all affect the quotation. Our LEV quote checklist helps you prepare the information for an enquiry.
