Just a quick one, have been attempting to locate some guidance re: assessment of risk posed by elevated concentrations of Carbon Monoxide ground gas.
We have a site which has been reporting levels ranging between 200 and 400ppm and I have turned up a blank in the usual places (CIRIA 665 etc) regarding the assessment of risk posed. Gas flow rates have been reported around 2l/hr during varying atmospheric conditions including falling.
Would be interesting to know if anyone has dealt with CO and what guidance is available to evaluate risks.
Thanks
Alex
