Confidence: Inferred — specific Director's Order number and full scope require verification with TSSA before publication-grade citation; the existence of a CO safety regime under TSSA Fuels Safety is Verified.

TSSA Director's Order FS-225-17 captures the carbon monoxide safety regime for gaseous fuels (natural gas and propane) in Ontario.

Livestock-specific application

CO detection is operationally non-negotiable in farrowing rooms and chick-brooder spaces. The combination is the textbook CO scenario:

• Propane combustion (CO production)
• Warmth (animal welfare requirement)
• Enclosed animals (cannot relocate)
• Minimum ventilation (energy economy)

Standard practice

Hard-wired CO detection in farrowing rooms and chick-brooder zones is standard practice on Ontario livestock operations. Battery-only residential-style detectors are insufficient at industrial scale and animal exposure.

Insurance context

Underwriters increasingly request CO-detection documentation as part of the farm policy renewal. CO detection in living-animal zones, propane piping integrity, and tank certification are commonly bundled as a single underwriting question.

Verification gaps

• Specific verbatim text of FS-225-17 should be confirmed against the current TSSA Fuels Safety Program publications before being quoted as regulation.
• Whether FS-225-17 is the current operative Order or has been superseded by a later FS-series Order should be re-checked.
