Oregon runs its own OSHA plan, so Ontario employers follow Oregon OSHA rules, not Idaho's federal setup. OAR 437-003-0020 adds to the federal 1926.51 toilet table. Construction projects costing $1,000,000 or more must have flush toilets plus wash basins with warm water and soap.
That $1,000,000 rule does not apply to highway work or to power, water, sewer or gas line projects. Smaller jobs still follow the federal toilet table. Ask Oregon OSHA if you are unsure which rule fits your project.
| Ontario site type | Oregon rule | What it requires |
|---|---|---|
| Construction under $1M | 1926.51(c) as used by Oregon OSHA | 1 toilet for 20 or fewer workers |
| Construction $1M and up | OAR 437-003-0020 | Flush toilets, wash basins, warm water, soap |
| Farm hand labor | OAR 437-004-1110 | 1 toilet and 1 handwashing facility per 20 workers |
Our deluxe flushing unit flushes and has a sink, with no hookup. Tell us your project size so we can quote the right mix. Read the Oregon OSHA construction toilet directive.
