Report: A farm scale anaerobic digester phase 1
Phase 1: Construction startup and Operation, Agriculture Canada Research Branch, Nov 1984

Safety standards at the digester site should be maintained at a high level, because the biogas is both toxic and explosive, extreme care should be taken when working in areas exposed to possible accumulations of biogas.
No smoking signs should be prominent and displayed in all areas. Explosion proof switches, fixtures, and motors, should be installed in any area where biogas can possibly collect.
Safety stanards for utilisation of digester gas such as CGAB105 and B149 are available from the Canadian Gas Association and should be reviewed and followed where applicable.
