Post warning signs and train employees about clearances approved before April 3, 1961.
You must
(1) Post warning signs near tracks with clearances approved before April 3, 1961, so employees are aware of the minimal clearances and their potential hazards. The signs must:
- Be highly visible
- Be easy to read
- Alert employees to the danger of railway equipment operating on your yard and plant tracks.
(2) Include in your employee safety and health training information about:
- Any minimal clearances and their location
- Potential hazards associated with them
- The location of any clearance warning signs.
Construct and maintain rail yard walkways for employee safety.
Important:
- You have 2 years from October 01, 2002, (the effective date of this rule construction requirements of this section), unless the department determines during an inspection that your walkways create a serious safety hazard.
- If you aren't sure a serious safety hazard exists in your workplace, you can request a free consultation from the department by calling your local L&I office.
Construction of walkways
You must
- Build walkways in rail yard areas where employees regularly work on the ground.
- Construct rail yard walkways that can be maintained in a safe condition:
- - With reasonably smooth walking surfaces
- - That won't interfere with track drainage.
- Use any of the following materials when constructing your walkway:
- - Crushed material that doesn't exceed 1 1/2 inches in size. For this rule, "1 1/2 inches in size" means one of the following (percentages refer to weight measurement and sieve size standard in the industry):
|
Smaller crushed material is preferred and should be used where drainage and durability isn't an issue. Crushed material that is 3/4 inch or less in size is recommended for switching leads in yards.
- Asphalt, concrete, planking, grating, or other similar material.
- Natural materials such as gravel or dirt.
You must
- Construct walkways wide enough for employees to safely perform their duties
- Construct walkways with a grade or slope in any direction with not more than one inch of elevation for each 8 inches of horizontal length, unless it is geographically impractical.
Maintenance of walkways
You must
- Keep all walkways clear of vegetation, debris, mud, or other obstructions that create a potential hazard for employees.
- Remove all standing water from all walkways as soon as reasonably possible.
- Reopen walkways temporarily closed for a construction project within thirty days after the project is completed.
- Repair walkways that have been damaged and temporarily closed because of an emergency within 30 days after the emergency ends.

Definition: Emergency: Any unforeseen occurrence endangering life, limb, or property.

Note: The requirements for filing a variance are located in the Safety and Health Core Rules, and chapter 296-900 WAC, Administrative rules. |
Install radiation detectors according to manufacturer's specifications.
Important:
This section applies only to those private yards and plants where the installation of radiation detectors beside railroad tracks is required due to the nature of the business; for example, scrap metal yards.
You must
- Install radiation detectors beside the railroad tracks in your yard and/or plant according to the manufacturer's specifications.
- Post signs on each radiation detector installed less than 8 feet 6 inches from the centerline of the track:
- - Warning employees that the side clearances between the detector and the track centerline are less than the required standard minimum side clearances found in this chapter
- - Prohibiting employees from riding on the side of any rail car passing through the detector.
Maintain overhead clearances.
| Exemption: Engine houses and car shops are exempt from the overhead clearance requirements of this section. |
You must
- Make sure overhead railroad clearances are at least 22 feet 6 inches unless a clearance requirement found in Table 1 applies.
|
|
Note: Clearance requirements are based on the assumption that generally used rail equipment in private yards and plants is no more than ten feet ten inches wide by fifteen feet six inches high.
|
Table 1 - Minimum Overhead Clearances for Buildings, Structures,
Tunnels, and Bridges
|

Maintain side clearances.
You must
- Make sure side clearances are at least 8 feet 6 inches from the track centerline unless clearance requirements found in Tables 2, 3, or 4 apply.
|
|
Note: All side clearances in Tables 2, 3, and 4 that reference the track centerline are based on the assumption that private rail operations generally use track that is standard gauge width (4 feet 8 1/2 inches). |

|
Note:
|
Maintain clearances between tracks.
You must
- Comply with the track clearance
requirements in Table 5.
Table 5 - Minimum Standard Gauge Track Clearances
|
|
|
Note: The following illustration will help you understand the track clearance requirements discussed in this section and WAC 296-860-20080 regulating narrow gauge rail operations. |
Standard Gauge Track Clearances

|
|
Note: Existing tracks may be extended at clearances lawfully prescribed prior to the effective date of this order. |
Move excessive height or width rail car loads with care.
|
|
Note: This section regulates rail cars whose dimensions exceed ten feet ten inches wide by 15 feet 6 inches high. |
You must
- Make sure your yard supervisor is given advanced notice regarding the arrival of any excess height or width cars so they can safeguard any employees working in the yard.
- Make sure no one is allowed to ride on the:
- - Roof of any excessive height car
- - Side of any excessive width car
- - Side of any car with a load extending more than 5 feet 5 inches from the car's centerline.
Follow these requirements to conduct narrow gauge rail operations.
You must
- Base your clearance measurements upon your widest narrow gauge cars.
- Make sure the distance between the cars and objects on narrow gauge track is equal to or greater than the distance required between ten foot ten inch wide cars and other cars or objects on standard gauge track.
- Comply with all other applicable requirements in this chapter.
