NOTE: Division 2/R, SPECIAL INDUSTRIES, contains both federal standards which have been adopted by reference, and Oregon-initiated rules. OAR 437-002-0300 is the rule which adopts by reference federal standards. Those which begin with the words “Reserved for” have not been adopted by reference.

NOTE: OAR 437-002-0301, Oregon Rules for Ornamental Tree and Shrub Services. These rules were first adopted by OR-OSHA Admin. Order 27-1990, filed 12/12/90, EFFECTIVE 2/1/91. An amendment was made to OAR 437-002-0301 by OR-OSHA Admin. Order 3-1994, filed 8/1/94, EFFECTIVE 8/1/94. Amended by OR-OSHA Admin. Order 1-1996, filed 2/16/96, effective 2/16/96.

NOTE: OAR 437-002-0312, Pulp, Paper and Paperboard Mills. These rules are a combination of federal rules from §1910.261 and Oregon rules in Division 75. Division 75 was repealed when these rules were adopted as Admin. Order 7-1994, adopted 11/4/94, effective 1/3/95.

This section of Division 2/R includes 3 federal standards which have been adopted by reference by OR-OSHA Admin. Order 14-1991, EFFECTIVE 11/1/91. These are 1910.262, Textiles; 1910.263, Bakery Equipment; and 1910.264, Laundry Machinery and Operations. These federal standards replaced Divisions 76, 77, and 78, which had identical titles.

The following federal standard on Sawmills (29 CFR 1910.265, with the exception of 1910.265(a)(1)) has been adopted by reference into Division 2/R, Special Industries (formerly Special Processes), by OR-OSHA Admin. Order 7-1993, filed 6/8/93, EFFECTIVE 8/1/93.

Oregon Division 79, Lumber, Plywood and Shingle Manufacturing, has been repealed with the adoption of 1910.265. However, several Oregon-initiated rules have been retained and renumbered as part of Division 2/R. These Oregon-initiated rules are for areas NOT covered by 1910.265 and include the following:

1. Additional Oregon rules for Sawmills;

2. Rules for Veneer and Plywood Machinery; and

3. Additional definitions and rules for Shake and Shingle Machinery.

NOTE: In Oregon, 1910.265(c) and (d) will continue to apply to plywood, cooperage and veneer, as was the case with Division 79.
§1910.266 PULPWOOD LOGGING. (Reserved)
NOTE: In Oregon, Pulpwood Logging rules are provided in OAR 437, Division 7, Forest Activities.
§1910.267 AGRICULTURAL OPERATIONS. (Reserved)
NOTE: In Oregon, Division 4, Agriculture, applies.
The following federal standard on Telecommunications (29 CFR 1910.268) has been adopted by reference into Division 2/R, Special Industries (formerly Special Processes), by OR-OSHA Admin. Order 11-1993, filed 8/4/93 EFFECTIVE 10/1/93, with the exception of 1910.268(a)(1), (b)(3), (d)(1), (f)(1), (n)(11)(iv) and (v), and (q).

Oregon Division 82, Telecommunications, was repealed when these rules were adopted. However, several Oregon-initiated rules have been retained and renumbered as part of Division 2/R in OAR 437-002-0316. These Oregon-initiated rules are for areas NOT covered by 1910.268 and include the following:

1. Additional applicability to telephone, TV cable and other signaling equipment centers;

2. Rules for employee protection in public workplaces, personal protective equipment, and training; and

3. Additional definitions.
Amended by OR-OSHA Admin. Order 1-1996, filed 2/16/96, effective 2/16/96.
The following federal standard 1910.269 on Electric Power Generation, Transmission and Distribution, has been adopted by reference into Division 2/R, Special Industries, by OR-OSHA Admin. Order 3-1994, filed 8/1/94, EFFECTIVE 8/1/94. Oregon-initiated rule 437-002-0317 has also been adopted to continue coverage historically provided in Oregon. See Note on page 2 for federal stays for some of the following rules.

NOTE: OSHA is staying the enforcement of the following paragraphs of §1910.269 until November 1, 1994: (b)(1)(ii), (d) except for (d)(2)(i) and (d)(2)(iii), (e)(2), (e)(3), (j)(2)(iii), (l)(6)(iii), (m), (n)(3), (n)(4)(ii), (n)(8), (o) except for (o)(2)(i), (r)(1)(vi), (u)(1), (u)(4), and (u)(5). OSHA is also staying the enforcement of paragraphs (n)(6) and (n)(7) of §1910.269 until November 1, 1994, but only insofar as they apply to lines and equipment operated at 600 volts or less. Further, OSHA is staying the enforcement of paragraph (v)(11)(xii) of §1910.269 until February 1, 1996.

Federal standard 29 CFR 1910.272, Grain Handling Facilities, has been adopted by reference into Division 2/R, Special Industries, by APD Admin. Order 10-1988, adopted and effective 7/7/88; amended by OR-OSHA Admin. Order 23-1990, adopted 9/28/90, effective 12/1/90; and amended by OR-OSHA Admin. Order 3-1996, adopted 7/22/96, effective 7/22/96.



Federal standards 29 CFR 1910.274, Sources of Standards, and 29 CFR 1910.275, Standards Organizations, have been adopted by reference into Division 2/R, Special Industries, by OR-OSHA Admin. Order 14-1991, adopted 10/10/91, effective 11/1/91.

NOTE: Oregon OSHA adopted by reference corrections and technical amendments issued by federal OSHA and published in the Federal Register. Federal OSHA made simple corrections, deleted redundant provisions, and clarified and reorganized various other provisions throughout the standards. OR-OSHA Admin. Order 4-1997 filed 4/2/97, effective 4/2/97.
NOTE: Federal OSHA published in the Federal Register the new Respiratory Protection Standard. The new standard replaces respiratory protection standards that were adopted in 1971 by OSHA. The new respiratory protection text is in general industry, 29 CFR 1910.134. The text previously in 1910.134 has been redesignated as 1910.139, Respiratory Protection for M. Tuberculosis. Four subdivisions in the Construction standard have also been amended. OR-OSHA Admin. Order 3-1998, filed 7/7/98, effective 7/7/98.
NOTE: This rulemaking repealed Oregon-initiated rule portion OAR 437-002-0316(10), Tree Trimming – Electrical Hazards, and the “NOTE” immediately preceding it, and replaced both by adopting 1910.268(q), Tree Trimming – Electrical Hazards. These amendments were made in OR-OSHA Admin. Order 3-1999, filed and effective April 30, 1999.
NOTE: Federal OSHA made amendments in general industry and construction in both safety and health standards that will revise or eliminate duplicative, inconsistent, or unnecessary regulatory requirements without diminishing employee protections. Changes being made to health standards include reducing the frequency of required chest x-rays and eliminating sputum-cytology examinations for workers covered by the coke oven and inorganic arsenic standards, and changing the emergency-response provisions of the vinyl chloride standard. Changes being made to OSHA safety standards include eliminating the public safety provisions of the temporary labor camp standard, eliminating unnecessary cross-references in the textile industry standards, and others. OR-OSHA Admin. Order 4-1999, filed 4/30/99, effective 4/30/99.
NOTE: Oregon OSHA removed a one-line paragraph in Division 2/R, General Industries/Special Industries. The specific paragraph is OAR 437-002-0312(4)(j)(C), concerning rail mounted cranes, in Oregon Rules for Pulp, Paper and Paperboard Mills. Federal OSHA requested we remove the paragraph in order to be as effective as their standard. OR-OSHA Admin. Order 2-2001, filed and effective 2/5/01.
NOTE: The current brush chipping rules found in Division 2/R, OAR 437-002-1910.269, Power Generation, OAR 437-002-0310(6)(a) through (r), Tree and Shrub, and Division 3/V, Construction/ Power Transmission and Distribution, Power Line Construction have different requirements. This has led to inconsistency in OR-OSHA’s requirements depending on the industry where the work is done.

Oregon OSHA consolidated the various rules from each division into one rule that will apply to all employees operating chippers. The new rule will be located in Division 2/R (general industry) as 437-002-0310 amended paragraph (6), and in Division 3/V (construction) as 437-003-0707.

There should be no additional cost to employers due to this rule consolidation. Employers that have worked under Division 2, General Industry, and Division 3, Construction, have already worked with all the rules. The new rules have been written and reorganized to make them easier to understand.

OR-OSHA Admin. Order 5-2001, filed and effective 4/6/01.


NOTE: OR-OSHA Admin. Order 12-2001, filed and effective 10/26/01.

Clarifies language about hearing protection for employees in shrub and tree services.


NOTE: Federal OSHA published, in the June 8, 2004 Federal Register, error corrections (typographical and reference) to four standards. Oregon OSHA’s standards must be at least as effective as federal OSHA, therefore, we are adopting the corrections.
The first correction deletes two references to a nonexistent table in the Mechanical Power-Transmission Apparatus Standard. The second is a correction of typographical errors in the Mechanical Power Presses Standard. The third correction is to a cross-reference in the Telecommunications Standard. The fourth correction is to a reference to a table contained in the Hazardous Materials Standard for Hydrogen.
These changes are in Oregon OSHA’s Divisions 2/H, 2/O, and 2/R. Federal OSHA amended CFR 1926.307 in the June 8, 2004 Federal Register. Oregon OSHA did not adopt 1926.307, therefore, it is not included in this rulemaking.
This is OR-OSHA Administrative Order 4-2004, adopted and effective September 15, 2004.

NOTE: Federal OSHA published in the September 13, 2005 Federal Register a final rule to delete from its standards three references to national consensus standards and two references to industry standards that are outdated. Deleting these references does not reduce employee protections. By eliminating the outdated references OSHA clarifies employer obligations under the applicable OSHA standards and reduces administrative burdens on employers and OSHA.
This final rule updates standards on hazardous materials, flammable and combustible liquids; general environmental controls, temporary labor camps; hand and portable powered tools and other hand held equipment, guarding of portable powered tools; welding, cutting, and brazing, arc welding and cutting; and special industries, sawmills. All in general industries standards.
Oregon OSHA adopts all these changes to remain at least as effective as Federal OSHA standards, with the exception of amending 1910.142 Temporary Labor Camps, which Oregon did not adopt. OAR 437-002-0142 Labor Camps, applies in Oregon.
This is OR-OSHA Administrative Order 4-2005, adopted and effective December 14, 2005.

NOTE: This rulemaking is to keep Oregon OSHA in harmony with recent changes to Federal OSHA’s standards.
Federal OSHA published in the December 27, 2011 Federal Register corrections of typographical errors and non-substantive technical amendments to a number of standards in general industry, construction, and shipyard employment. The technical amendments include updating or revising cross-references. These revisions do not affect the substantive requirements or coverage of those standards, do not modify or revoke existing rights or obligations, and do not establish new rights or obligations.
Oregon OSHA adopts these corrections and amendments to the standards Oregon has adopted previously to reflect federal OSHA’s changes. We are also making rule reference changes in a number of standards to reflect the newly adopted OAR 437-002-0134 Personal Protective Equipment.
This is Oregon OSHA Administrative Order 1-2012, adopted and effective April 10, 2012.

NOTE: Oregon OSHA adopts new rule, OAR 437-002-0146 Confined Spaces, which replaces 1910.146 Permit-Required Confined Spaces, in Division 2/J General Environmental Controls. This expands the scope of the new rule to include the construction industry.
During the 2011 proposal, several issues were discovered that needed to be resolved. We reconvened our stakeholder groups to resolve those issues and addressed any other areas for clarification. The identified issues include: revising and including several definitions, language for closing permits, ensuring employee access to written materials, ensuring all actions required by the permit are followed, and clarifying when alternate entry cannot be used.
Other areas amended for clarification include:

Permit Space Program.

  • Changed the requirement to catalog all confined spaces to catalog all permit spaces.

  • If the permit program needs to be revised, the language was changed that prohibiting entry into any space; to any space that is affected by that revision until the revision is complete.


Evacuation. Added language on what to do if entrants need to evacuate a permit space.
Decontamination. There was language requiring patient decontamination. The group consensus was to move this language to the appendix on rescue. In its place, language was added requiring MSDSs and providing them to the medical providers.
Rescue.

  • For non-entry rescue – modified the language to include a rescue person, as the rescue “team” may only consist of the attendant retrieving the entrant from the space.

  • For entry rescue – language change from ensuring the rescue team can proficiently perform rescues to ensuring rescue teams can efficiently perform rescues.

  • Added language requiring that, if a third-party rescue service is used, that the agreement is in writing.


Alternate Entry.

  • Changed the language in the exception for alternate entry.

  • Added language to specify which parts of the rule don’t apply when one uses alternate entry.

  • Added a condition on when the space must be evacuated during alternate entry (new hazard or conditions change).


Training. Moved the awareness training piece to the bottom of the training section to avoid confusion and clarified that it is only for employees who work around permit spaces.
Records. Modified the record retention section to refer back to the rule that requires a review of the permit program.
The requirements of this standard are similar to the requirements of the existing general industry standard, but are written to clarify employer obligations and eliminate confusing requirements.

This rulemaking amends Oregon-initiated rules OAR 437-002-0182, 437-002-0256, and 437-002-0312 to update the rule reference to the new Oregon rule 437-002-0146 Confined Spaces. Also amended to reflect the new Confined Spaces rules are 1910.120 Appendix E, and 1910.269 that currently refer the reader to 1910.146. We also repealed 1926.21(b)(6) in Division 3/C and placed a note referring the reader to Division 2/J, 437-002-0146 Confined Spaces.


This is Oregon OSHA Administrative Order 6-2012, adopted September 28, 2012, and effective April 1, 2013.

NOTE: This rulemaking is to keep Oregon OSHA in harmony with recent changes to federal OSHA’s standards.
Oregon OSHA amends standards in Division 2, general industry, and Division 3, construction, to reflect federal OSHA updates published in the June 13, 2013 Federal Register. Also included in this rulemaking are minor corrections from federal OSHA of the June 13, 2013 Federal Register with the November 6, 2013 Federal Register. Corrections are to addresses and reference clarification for graphics. Federal OSHA updated its general industry and construction signage rules by adding references to the latest version of the American National Standards Institute (“ANSI”) standards on accident prevention signs and tags, ANSI Z535.1-2006 (R2011), Z535.2-2011 and Z535.5-2011. OSHA retained references to the earlier ANSI signage standards, ANSI Z53.1-1967, Z35.1-1968 and Z35.2-1968. This rulemaking provides employers the option to comply with either the earlier or updated standards.
Federal OSHA amended 1926.201 and 1926.202 concerning the Manual on Uniform Traffic Control Devices (MUTCD). Oregon repealed these two standards and has Oregon-initiated rule 437-003-0420 Traffic Control, instead. OAR 437-003-0420 currently references the most current editions, therefore we did not amend with this Federal Register publication.
Federal OSHA amended 1910.261 with updated ANSI standards. In Oregon we have Oregon-initiated rule 437-002-0312 Oregon Rules for Pulp, Paper and Paperboard Mills, which we also amended to reflect the newer ANSI references.
This is Oregon OSHA Administrative Order 7-2013, adopted and effective December 12, 2013.

NOTE: In November 2014, Oregon OSHA proposed to adopt Federal OSHA final rules for Electric Power Generation, Transmission, and Distribution, that were published in the April 11, 2014 Federal Register. The proposal included Oregon-initiated changes to the federal rule. Three public hearings were held during November and December of 2014 resulting in several written comments and oral testimony before the comment period closed on December 12, 2014. Most of the comments received concerned the two worker rule exceptions. As a result of the comments received, Oregon OSHA decided not to adopt the rule as proposed in 2014, but to consider an alternative approach.
Two stakeholder meetings were conducted in the first half of 2015 to discuss comments along with potential changes to the 2014 proposal. Oregon OSHA received input and support from stakeholders to combine the Electric Power Generation, Transmission, and Distribution standards in Divisions 2/R and 3/V into one rule. Oregon OSHA merged 1910.269, in Division 2/R General Industry, and Division 3/V in Construction, standards into the new Division 2/RR. Unifying language and Oregon-unique rules for Power Generation, Transmission and Distribution for General Industry and Construction were incorporated into one standard.
In July, 2015 Oregon OSHA reposed rules for Electric Power Generation, Transmission, and Distribution. Three public hearings were held during August and September 2015. Most of the oral and written comments received concerned: the duties of a Safety Watch, the exception to the two-worker rule, and helicopters. Changes to the final rule include:
Safety Watch: Safety Watch text was added to the final rule 437-002-2311(13).
Operating switches: 437-002-2311(2)(b)(B) was changed to clarify that 437-002-2311(2)(b)(E) must be followed for routine switching of load break elbows.
Helicopters: Paragraphs were removed which were already addressed by, or were in conflict with, other regulatory agencies; or were unnecessarily restrictive based upon accepted industry practices.
On October 5, 2015 Federal OSHA published in the Federal Register, minor language clarifications in rules related to Line Clearance Tree Trimming as well as correcting errors in Table R-6 (Alternative Minimum Approach Distances.) The note for enclosed spaces was removed from Appendix A-3 and placed in Appendix A-5. These corrections have been incorporated in Oregon OSHA’s final rules.
This is Oregon OSHA Administrative Order 3-2015, adopted October 9, 2015, and effective January 1, 2016.

Oregon-initiated rules are printed in italics.

437-002-0310 Work Procedures.


  1. Climbing.

    1. A tree worker shall be tied in with an approved type of climbing rope and safety saddle when working 10 feet above the ground. The climbing rope shall always be used even when working from a ladder or scaffold and the employee is 10 feet or more above the adjacent ground line. A safety strap or rope with snaps may be used for additional protection.

    2. Limbs shall be inspected, while climbing, before applying weight. The climber shall not trust the capability of a dead branch to support his/her weight. Dead branches shall be broken off on the way up, if possible. Hands and feet shall be placed on separate limbs, if possible.

    3. The climbing rope shall be passed around the trunk of the tree as high as possible using branches with a wide crotch to prevent any binding of the safety rope. The crotch selected for tying in shall be over the work area as much as possible, but located in such a way that a slip or fall would swing the worker away from any electrical conductor. The rope shall also be passed around the main leader or an upright branch, using the limb as a stop. Feet, hands, and ropes shall be kept out of tight V-shaped crotches.

    4. The location of all electrical conductors shall be noted in relation to work procedures. The worker shall climb on the side of the tree that is away from electrical conductors, if possible.

    5. A figure-eight knot shall be tied in the end of the rope, particularly in the case of high trees. This will prevent pulling the rope accidentally through the taut line-hitch and possible serious injury from a fall.

    6. The climbing line shall be crotched as soon as practical after the worker is aloft, and a taut line-hitch tied and checked.

    7. The worker shall be completely secured with the climbing line before starting operations.

    8. The worker shall remain tied in until the work is completed and the worker has returned to the ground. If it is necessary to recrotch the rope in the tree, the worker shall retie the rope or use the safety strap before releasing the previous tie.

  1. Pruning and Trimming.

    1. Pole pruners and pole saws shall be hung securely in a vertical position to prevent dislodging. Pole pruners or pole saws shall not be hung on utility wires or cables, or left in the tree overnight. Pole saws shall be hung so that the sharp edge is away from the worker.

    2. A scabbard or sheath shall be hooked to the belt or safety saddle to carry the handsaw when not in use.

    3. Warnings, when necessary, shall be given by the worker in the tree before a limb is dropped.

    4. A separate line shall be attached to limbs which cannot be dropped or are too heavy to be controlled by hand. The line shall be held by workers on the ground end of the rope. Use of the same crotch for both safety rope and work rope shall be avoided.

    5. Cut branches shall not be left in trees overnight.

    6. A climbing rope shall never be left in a tree overnight. A service line shall be put up for overnight or longer.

    7. The climber shall inspect the rope for cuts or abrasions before starting work. If any cuts or serious abrasions are found, the rope shall be discarded, used for some other purpose, or the defective section cut off.

    8. During all tree working operations aloft, there shall be a second worker in the vicinity. This shall not apply to utility workers engaged in tree trimming incidental to their normal occupation, or to one-man service crews.

  1. Cabling.

    1. In cabling operations, branches which are to be cabled shall be brought together to the proper distanced by means of a block and tackle, a hand winch, a rope, or a rope with a come-along.

    2. Not more than two persons shall be in the tree working at opposite ends during cabling installation.

    3. When releasing the block and tackle, workers in trees shall be off to one side in case the lag hooks pull out under strain.

    4. Ground workers shall not stand under the tree when cable is being installed.

    5. Tools used for cabling, bark tracing, cavity work, etc., shall be carried in a bag or belt designed to hold tools, not put in the pocket or stuck in the top of a boot.

  1. Topping.

    1. Workers doing topping shall make sure the trees are able to stand the strain of a topping procedure. If not, some other means of lowering the branches shall be provided, such as a tree crane.

    2. If large limbs are lowered in sections, the worker in the tree shall be above the limb being lowered.

    3. Guidelines, handlines, or tag lines shall be used when conditions warrant their use.

  1. Felling.

    1. Before beginning any felling operation, a safety plan shall be developed which shall consider:

      1. The tree and the surrounding area for anything that may create a hazard when the tree falls;

      2. The shape of the tree;

      3. The lean of the tree;

      4. Wind force and direction;

      5. Decayed or other weak spots; and

      6. The location of other persons or structures.

    2. The work area shall be cleared to permit safe working conditions, and an escape route shall be planned before any cutting is started.

    3. Each tree worker shall be instructed as to exactly what is to be done during the felling operation. All workers not directly involved shall be at least two tree lengths away from the tree being felled.

    4. A notch and backcut shall be used in felling trees over 5 inches diameter breast high. No tree shall be felled by “ripping” or “slicing” cuts.

    5. The depth or penetration of the notch shall be approximately one-third the diameter of the tree.

    6. The opening or height of the notch shall be approximately 2-1/2 inches for each foot in diameter of the tree.

    7. The backcut shall be made higher than the point or apex of the notch to prevent kickback.

    8. Just before the tree is ready to fall, an audible warning shall be given to those in the area.

    9. If there is danger that the tree being felled may fall the wrong way or damage property; wedges, block and tackle, rope, or wire cable (except where an electrical hazard exists) shall be used. All limbs shall be removed from trees to a height and width sufficient to allow the tree to fall clear of any wires and other objects in the vicinity.

    10. Special precautions in roping rotten or split trees shall be taken to prevent the tree from falling in an unexpected direction even though the cut is made on the proper side.

    11. The faller shall retreat to a safe location when a tree is committed to fall.

  1. Chipper equipment and operation.

Equipment Design

    1. Enclose chipper rotating components in a housing capable of retaining broken chipper knives or foreign material.
