A local exhaust ventilation preventive maintenance schedule lists the checks and jobs done on the equipment at fixed intervals, how long each takes, and in what order of frequency, so problems are found before the local exhaust ventilation fails. This page gives the schedule used in the PlantOps360 task library for local exhaust ventilation (and fume extraction system), which follows common industry practice for general-purpose equipment. It is also searched for as LEV, fume extraction, welding fume extractor, exhaust hood.
The maker’s manual and your site safety procedures always come first where they differ. Intervals set by law differ by state.
Local exhaust ventilation preventive maintenance schedule and checklist
| How often | Task | Estimated time |
|---|---|---|
| Daily | Check capture hoods and arm positions; check fan operation and airflow indicator | 5 min |
| Weekly | Check ducts for damage and leaks; empty dust bins | 15 min |
| Monthly | Check filter differential pressure and clean or replace filters; check fan belts | 30 min |
| Quarterly | Measure hood face velocity and duct velocity; compare with commissioning values | 60 min |

| Annual | Annual thorough examination and test of the system by a competent person | 240 min |
Local exhaust ventilation maintenance frequency and yearly workload
At the estimated times, one local exhaust ventilation needs about 61 hours of preventive maintenance a year. The biggest single job is “Annual thorough examination and test of the system by a competent person” at 240 minutes, done annual. Multiply by the number of units you have to see the workload for your plant.
| Frequency | Tasks | Time per round | Hours per year |
|---|---|---|---|
| Daily | 1 | 5 min | 30.4 h |
| Weekly | 1 | 15 min | 13.0 h |
| Monthly | 1 | 30 min | 6.0 h |
| Quarterly | 1 | 60 min | 4.0 h |
| Half-yearly | 1 | 120 min | 4.0 h |
| Annual | 1 | 240 min | 4.0 h |
What goes wrong on a local exhaust ventilation without preventive maintenance
- Poor capture at hoods
- Fan and duct faults
- Filter loading
- Damaged ducts and leaks
What to watch between services
- Hood capture and arm position
- Filter differential pressure
- Fan operation and duct condition
Safety and statutory notes for local exhaust ventilation maintenance
Extraction protects workers from fumes and dust. Test airflow at the interval the exposure rules or your safety plan require.
