Oregon OSHA vs. federal OSHA: construction rules that differ
Oregon keeps the federal 6-foot fall protection trigger but adds personal fall restraint and limits warning lines on roofs to slopes of 2 in 12. It also requires guarding steel erection openings as soon as they are created, 2 business days’ notice before work near overhead high-voltage lines, and a PPE hazard assessment.
Who the state plan covers
Oregon OSHA covers private and public (state and local government) employers in Oregon. On construction sites, OAR 437 Division 3 applies: it adopts most of 29 CFR 1926 by reference and adds or substitutes Oregon rules, and Oregon’s general rules in other divisions apply where a hazard is not limited to construction (OAR 437-003-0005).
Where the rules differ
Fall protection trigger height
Same 6-foot trigger. Oregon repealed 1926.501(a) and (b) and replaced them with OAR 437-003-1501, which keeps 6 feet but points to Oregon’s own criteria rules, including personal fall restraint (437-003-0502). Measure and protect at 6 feet exactly as you would under federal OSHA.
(b)(1) Unprotected sides and edges. Each employee on a walking/working surface (horizontal and vertical surface) with an unprotected side or edge which is 6 feet (1.8 m) or more above a lower level shall be protected from falling by the use of guardrail systems, safety net systems, or personal fall arrest systems.Source
(1) General. Except where permitted by another standard, when employees are exposed to a hazard of falling 6 feet or more to a lower level, the employer must ensure that fall protection systems are provided, installed, and implemented according to the criteria in 1926.502, 437-003-0502, 437-003-1502, and 437-003-2502.Source
Personal fall restraint and body belts
Federal Subpart M bars body belts in fall arrest. Oregon adds a separate personal fall restraint rule that lets a body belt be used when the system is rigged so the worker cannot fall any distance. On site, a body belt is acceptable in Oregon only as restraint, never as arrest.
(d) Personal fall arrest systems. Personal fall arrest systems and their use shall comply with the provisions set forth below. Effective January 1, 1998, body belts are not acceptable as part of a personal fall arrest system.Source
(1) Personal fall restraint systems shall be rigged to prevent the user from falling any distance. (2) Fall restraint systems must use fall arrest system components that conform to the criteria in 1926.502, except as otherwise provided for in this section. Exception: A body belt may be used in fall restraint systems.Source
Warning lines and safety monitors on roofs
Federal rules allow warning-line and safety-monitoring combinations on any low-slope roof, which 1926.500(b) defines as 4 in 12 or less. Oregon stops warning lines (and, under 437-003-2502, safety monitoring) at 2 in 12. On a 3-in-12 or 4-in-12 roof in Oregon, use guardrails, nets, fall arrest or fall restraint instead.
(10) Roofing work on Low-slope roofs. Except as otherwise provided in paragraph (b) of this section, each employee engaged in roofing activities on low-slope roofs, with unprotected sides and edges 6 feet (1.8 m) or more above lower levels shall be protected from falling by guardrail systems, safety net systems, personal fall arrest systems, or a combination of warning line system and guardrail system, warning line system and safety net system, or warning line system and personal fall arrest system, or warning line system and safety monitoring system.Source
(1) A warning line system shall not be used as fall protection on roof slopes greater than 2 in 12 (vertical to horizontal). (2) Employees performing roofing work between a roof edge and a warning line must be protected by a personal fall arrest system, personal fall restraint system, guardrail system, safety net system, or safety monitoring system.Source
Roof and floor openings during steel erection
Federal steel erection rules protect openings that cannot be decked under 1926.760(a)(1), which starts at 15 feet. Oregon’s replacement rule requires covers or guardrails around those openings as soon as they are created, with no height threshold. Cover or guard elevator shafts and stairwells on every level as they open up.
(ii) Roof and floor holes and openings shall be decked over. Where large size, configuration or other structural design does not allow openings to be decked over (such as elevator shafts, stair wells, etc.) employees shall be protected in accordance with § 1926.760(a)(1).Source
437-003-1754 Roof and floor holes and openings. Roof and floor holes and openings shall be decked over. Where large size configuration or other structural design does not allow openings to be decked over (such as elevator shafts, stairwells, etc.) employees shall be protected by covers or guardrail systems erected around such openings as soon as the openings are created.Source
Work near overhead power lines
Both use a 10-foot zone for lines up to 50 kV. Oregon adds a notice step: whoever is responsible for the planned activity must notify the line owner at least 2 business days before work inside the restricted space. Build that call into the schedule before cranes, lifts or material handling get close to the line.
(6) All equipment covered by this subpart shall comply with the following requirements when working or being moved in the vicinity of power lines or energized transmitters, except where electrical distribution and transmission lines have been deenergized and visibly grounded at point of work or where insulating barriers, not a part of or an attachment to the equipment or machinery, have been erected to prevent physical contact with the lines: … (i) For lines rated 50 kV or below, minimum clearance between the lines and any part of the crane or load shall be 10 feet;Source
(a) For lines rated more than 600 V to 50 kV, restricted space extends 10 feet in all directions from the surface of the line or equipment. … Proper Notification. The person(s) responsible for the planned activity must notify the owner/operator of the line or equipment, at their business office, at least 2 business days prior to the anticipated beginning of work (business days are Monday through Friday, excluding federal and state holidays).Source
Swing radius of excavators and other equipment
The federal swing-radius barrier rule sits in the cranes and derricks subpart. Oregon’s pinch-point rule covers any mechanical equipment with a rotating superstructure, such as an excavator, and calls for a warning barricade when someone must work within 3 feet of the swing radius. It also requires DANGER – STAY CLEAR signs on all sides.
(ii) Erect and maintain control lines, warning lines, railings or similar barriers to mark the boundaries of the hazard areas.Source
(4) When the nature of the work requires a person to work within three feet of the swing radius of the rotating upper structure, a warning barricade shall be provided.Source
PPE hazard assessment and training
Oregon replaced 1926.95, 1926.100, 1926.101 and 1926.102 with its own PPE rule. It requires the employer to assess the workplace for hazards, select PPE from that assessment, and train each worker before they do work requiring PPE. Keep a site PPE hazard assessment for Oregon jobs.
(a) Application. Protective equipment, including personal protective equipment for eyes, face, head, and extremities, protective clothing, respiratory devices, and protective shields and barriers, shall be provided, used, and maintained in a sanitary and reliable condition wherever it is necessary by reason of hazards of processes or environment, chemical hazards, radiological hazards, or mechanical irritants encountered in a manner capable of causing injury or impairment in the function of any part of the body through absorption, inhalation or physical contact.Source
(a) The employer must assess the workplace to determine if hazards are present, or are likely to be present, which necessitate the use of personal protective equipment (PPE) or other protective equipment.Source
Also worth knowing
- Employers must run a safety committee or hold safety meetings; when more than half of the employees report to construction sites, either option is allowed (OAR 437-001-0765).
- Heat illness prevention requirements apply whenever work is done where the heat index equals or exceeds 80 degrees Fahrenheit (OAR 437-002-0156).
- Wildfire smoke rules apply when PM2.5 reaches 35.5 µg/m3, an AQI of 101 (OAR 437-002-1081).
- Traffic control devices, flagging and barricades for work on or next to a roadway must follow the MUTCD, replacing 1926.201–1926.203 (OAR 437-003-0420).
Common questions
Is the Oregon construction fall protection height different from federal OSHA?
No. OAR 437-003-1501(1) uses the same 6-foot trigger as 29 CFR 1926.501(b)(1). The difference is in the systems: Oregon also recognizes personal fall restraint under OAR 437-003-0502 and limits warning lines to roof slopes of 2 in 12 or less.
Can workers use a body belt in Oregon?
Only in a fall restraint system. OAR 437-003-0502 allows a body belt when the system is rigged so the worker cannot fall any distance. For fall arrest, 29 CFR 1926.502(d) still applies and body belts are not acceptable.
Do I need to call the utility before working near power lines in Oregon?
Yes, if the work will enter the restricted space (10 feet for lines over 600 V up to 50 kV). OAR 437-003-0047 requires the person responsible for the activity to notify the line owner or operator at least 2 business days before the work starts.
