Hello All

Does anybody have any advice on monitoring of air quality in enginnering workshops?

Most machines are enclosed with LEV fitted and there is good extraction for the open machines (which are only used intermittently). Welding bays have LEV installed. All exhaust ventilation systems are monitored and maintained.

Is air sampling considered necesary is this environment?

Thanks in advance

Hi TripleS65

I broadly agree with Ian.

Suggest you look at the design specification for the LEV at enclosed machines and welding areas to check that (a) this wasn't just cobbled together and (b) that the processes are roughly the same as intended when the LEV was designed and installed.

Then for the intermittently used machines that are NOT enclosed, consider what is likely to be discharged into the environment in inhalable or respirable form. Since we don't know what tasks these machines are performing, it's impossible to guess what nasties might be given off.

Also make sure that people are using the elephants trunk type extraction systems correctly. It’s not good positioning the capture nozzle a foot away from where the welding is taking place. It needs to be inches from the source of the fume.
