Emissions Monitoring & LEV Testing
Also known as Stack Sampling or Source Testing, this is a requirement for many companies that have polluting manufacturing processes.
If you require a permit from your Local Authority to operate a polluting process involving emissions to atmosphere, it’s likely that you will need to measure the concentration of gases or particulate matter in the gas stream as it leaves your plant.
Common substances that need to be monitored include particulates, volatile organic compounds (VOCs), ammonia, formaldehyde, nitrogen oxides, etc. We can carry out the necessary measurements and help you fully comply with your permit conditions.
If you are in the process of applying for a permit from your Local Authority under the PPC Regulations and need to be thinking about implementing suitable control strategies at this early stage, it’s often worthwhile obtaining some early measurements to help with your forward planning.
If you have local exhaust ventilation (LEV) systems, be they spray booths, welding hoods, exhaust slots on degreasing-baths or larger multi-point systems, the law says they must be thoroughly examined and tested at least every 14 months.
Typical test parameters:
- Visual inspection for damage or corrosion
- Pressure drop across fan
- Pressure drop across bag filters or other arrestment plant
- Pressure behind exhaust hoods
- Air flow rate through main system and branch ducts
- Air flow rate at booth face, or in front of exhaust hood
- Visualisation of air flow characteristics at contamination source or containment interface
Information provided by the examination & test:
- Is the system likely to provide adequate control & containment?
- Does the system meet minimum standards of effective design and performance?
- Has there been any change in performance since the previous test?
- What action is necessary to achieve satisfactory performance?
- What maintenance/repairs will be needed to prevent foreseeable loss of efficiency?
Keep your reports!- you will need them:
- Records must be kept 5 years
- HSE inspectors will always want to see them
- An essential element in defending compensation litigation
