Ever wondered how dangerous a broom is?
A standard broom can be one of the most dangerous items you might find on a construction site, aside from the cartoon image of standing on the end and the handle hitting you in the face, the humble broom can cause a massive spike in reducing air quality around both the user and anyone close by.
This example was a quick brush of a standard garage floor within a metre of a monitor, the spike in both PM10 and PM2.5 is quick and potentially deadly, if your job is sweeping up.
It should also be noted it takes a long time to resettle back to a normal reading, however, this will depend on the air flow in the area the broom was used.
