monoxide (CO) and Lower Explosive Limit (LEL) is undertaken using a Rae Systems
MultiRae gas monitor which continuously measures gas levels in ambient air. The monitor was located at
the eastern boundary of the site (Figure 3) and records maximum, mean, and minimum CO levels, and the
percentage of the LEL. The instrument was deployed on 3 May 2024 and recovered on 6 May 2024 and
recorded data for 72 hours.
The concentration of PM10 in ambient air was measured using a TSI DustTrak aerosol
