*3M Canada does have this equipment available. The recommended respirators for use with low concentrations of manure are detailed in the Choose a Respirator section of this site. Due to the high costs involved in purchasing a SCBA (self-contained breathing apparatus), these products are not featured in the Choose a Respirator section. The Farm Safety Association suggests that this equipment be used only by trained individuals and that the local fire department or similar emergency service could be contacted for this equipment.
