Scaffolding remains one of the leading causes of injuries in construction, with approximately 4,500 scaffold-related injuries each year. Many of these incidents are tied to scaffold platform failures that could’ve been flagged beforehand. In many cases, these accidents are preventable through proper communication and consistent inspection routines.
One of the most effective ways to prevent the use of unsafe or off-limits scaffolding is to implement a clear and reliable scaffolding tagging system. That starts with understanding the OSHA scaffold tagging requirements, including the various color codes and their proper application.
Key Takeaways
-
Scaffold tags help prevent accidents by clearly showing whether a scaffold is safe, restricted, or unsafe to use.
-
OSHA requires a competent person to inspect scaffolds for visible defects before each work shift and after any event that could affect structural integrity.
-
Scaffolding tags should list the inspection date, the name or initials of the inspector, and any load limits or usage notes to clearly show the scaffold’s safe use conditions.
-
Tags must be placed at every scaffold access point; hidden or hard-to-see tags defeat their purpose and put workers at risk.
What Are Scaffolding Tags?
Scaffolding tags are color-coded labels attached to scaffolding structures in construction and maintenance settings to indicate their safety status following an inspection by a competent person. These tags are a common industry practice to communicate whether a scaffold is ready for use, requires caution due to limitations, or is unsafe and prohibited from use.
Scaffold inspection tags are typically made from durable materials like heavy-duty plastic or weather-resistant card stock, and they include fields for recording inspection dates, the inspector's name or signature, and any notes on restrictions or defects.
OSHA Scaffold Tag Requirements
The Occupational Safety and Health Administration (OSHA) outlines the guidelines and requirements for scaffolding safety under 29 CFR 1926.451. Although OSHA regulations don’t mandate the use of scaffold tags specifically, section 1926.451(f)(3) requires a competent person to inspect scaffolds for visible defects before each work shift and after any event that could affect structural integrity.
Scaffold tags support this requirement by providing a clear, visible record of inspections and the scaffold’s status, helping meet OSHA scaffold tagging requirements and keeping the jobsite safer.
Scaffolding Tag Information Requirements
Important information must be included on scaffolding tags to convey the scaffold's safety status accurately. The following details should be clearly displayed on the tags:
-
-
Identification: Each scaffolding tag should have a unique scaffold identification number or code, allowing for easy identification and tracking purposes.
-
Inspection Date: The date of the scaffold's most recent inspection should be written on the tag, ensuring workers are aware of when the scaffold was last assessed for safety.
-
Load Capacity: The maximum load capacity of the scaffold must be clearly stated on the tag to help prevent overloading, which can compromise the scaffold's stability.
-
Inspection Results: Any findings or observations from the inspection should be recorded on the tag, noting any identified defects as well as changes such as modification, damage, or partial dismantling.
-
Safety Status: It should include the status of the scaffold, such as "Safe," "Unsafe-Do Not Use," or "Unsafe-Use with Caution."
-
The safety tag must reflect the scaffold’s actual condition: accurate, up to date, and filled out by someone authorized to do so.
Types of Scaffolding Tags and Color Codes

Different scaffold tag colors are used to show the current safety and inspection status of a scaffold. This color-coding system is a widely used industry practice that helps communicate scaffold conditions clearly, reduces misunderstandings, and works well even in a work setting with language differences. The most common scaffold tag colors are:
Green Scaffolding Tags
Green tags (“OK” Tags) indicate that a competent person has inspected the scaffold and it is safe to use. They signify that the scaffold complies with safety standards and gives workers the go-ahead to use the scaffold without restrictions. Common tag labels include phrases like “Safe for Use” or “Approved for Access.”
Yellow Scaffolding Tags
Yellow tags (Caution Tags) indicate that the scaffold has been inspected, but with restrictions or special conditions. These scaffold identification tags are often used when a scaffold is still being modified, lacks full scaffold components (like guardrails or scaffold planks), or when specific safety gear, such as fall protection, is required for access. They should not be removed until the scaffold has returned to a safe condition and has been re-inspected.
Red Scaffolding Tags
Red tags (Danger Tags) are used to indicate that the scaffold is not safe to use and must remain off-limits until necessary repairs or replacements have been made. These warning tags are applied when a scaffold hasn’t been inspected, is incomplete, or has visible structural issues. Red tags remain in place until a follow-up inspection confirms the scaffold is safe and a new tag (typically green) is applied.
Scaffolding Tagging System Best Practices

To ensure effective communication and visibility, follow the proper placement guide below:
Place tags at all access points to the scaffold, from ground-level to elevated access points such as ladders, stairways.
Position tags at eye level or in a conspicuous location where they are easily noticeable. Typically, this is at the base of the access ladder or entry platform.
Tags should not be obscured by equipment, materials, or other structures.
Scaffold safety tags should be properly tied to a fixed part of the scaffold structure, such as a guardrail or ladder rung, using durable materials.
If a scaffold spans several stories or sections, each segment should be tagged individually. Don't rely on one tag for an entire system. This prevents confusion, especially when parts are under construction or being dismantled. Some states may also have additional requirements for tag placement or content, so always check local safety regulations.
Case Study: Hidden Yellow Tag Leads to Injury
A worker climbed a scaffold where a yellow tag had been placed behind a vertical post, completely out of view from the main access point. With no visible warning, he assumed the scaffold was approved for use. While shifting his position, he lost balance near the edge where the midrail was missing. He slipped and landed awkwardly, resulting in a knee injury, missed workdays, and a reportable safety incident.
Although the yellow tag included the correct information, it failed in its main purpose: to alert the worker before he stepped onto the platform. The injury could have been avoided if the tag had been placed where it was clearly visible at the point of access. When a tag can’t be seen while climbing or approaching the scaffold, it’s as good as not being there at all.
Scaffolding Tags Inspection and Maintenance
Just like the scaffold itself, scaffolding tags require regular inspection and maintenance. Inspectors or competent persons should include the examination of tags as part of routine scaffold inspections. During these thorough inspections, tags should be checked for legibility, accuracy of information, and any signs of damage or wear. Any damaged or missing tags should be replaced immediately to maintain effective communication and safety compliance.
Scaffolding Tagging System FAQs
Who is responsible for inspecting the scaffold and its components before every work shift?
A competent person is responsible for inspecting the scaffold and its components before each work shift. This individual must be capable of identifying existing and predictable hazards and authorized to prompt corrective measures.
What should workers do if they notice a scaffold with a missing or damaged tag?
If workers notice a scaffold with a missing or damaged tag, they should immediately notify their supervisor or the responsible person in charge of scaffolding safety. It is crucial to address the issue promptly to avoid any confusion or potential risks.
Can subcontractors be held responsible for scaffolding tag compliance?
Yes, subcontractors can be held responsible for scaffolding tag compliance. While the primary contractor typically bears the ultimate responsibility for safety compliance on a construction site, subcontractors are also accountable for ensuring that scaffolding tags are properly used and maintained according to the established guidelines.
Can digital or electronic tagging systems be used instead of physical tags?
Yes, digital or electronic tagging systems can be used as an alternative to physical tags. These systems offer the advantage of real-time data management, instant updates, and easier record-keeping. However, it is important to ensure that the chosen digital tagging system meets the necessary regulatory requirements and provides clear visibility of the safety status to workers.
Can scaffolding tags be customized to include additional information?
Yes, scaffolding tags can be customized to include additional information, as long as the required OSHA information is clearly visible and legible. However, it is essential to ensure that the customization does not compromise the readability or effectiveness of the tags.
