Standardized specification BNQ 1809-350
Construction - Rock Blasting - Preventing Carbon Monoxide Poisoning

Safety measures are of the utmost importance in rock blasting. To protect residents near construction sites as well as contractors and their employees from carbon monoxide poisoning, the BNQ has developed the Standardized specification BNQ 1809-350. It sets out requirements for reducing the risk of carbon monoxide poisoning during rock blasting on construction sites.

The Standardized specification is for general contractors, special trade contractors, individuals and corporations writing documents for construction that requires rock blasting.

TheStandardized specification BNQ 1809-350 does not deal specifically with preventing carbon monoxide poisoning in mining operations or gravel pits, but it may be possible to apply it in whole or in part. In that case, the mine or gravel pit operator is responsible for verifying that the Standardized specification applies to its operations. Note that the Standardized specification does not apply to the secondary blasting of completely excavated glacial boulders that are uncovered on all sides except the bottom.
