Why Scaffold Tags Are Different Colors

Safety is always the top priority when you’re on a construction site, and scaffold tags are a big part of that equation. You’ve probably seen those bright tags clipped to the scaffolding near access points, but do you know what each color means?

In this quick guide, we’ll break down the color-coded system of scaffold tags, explain how to use them effectively, and toss in a bit of scaffold trivia for good measure. Whether you're a seasoned pro or just getting started, it never hurts to brush up on the basics.

What Are Scaffold Tags?

Scaffold tags are part of a visual inspection system used to communicate the status and safety of a scaffold structure. These tags help ensure that only safe, inspected scaffolding is in use—and that everyone on site knows what’s good to go (and what’s not).

Typically, tags are placed at scaffold access points and updated as needed by a competent person—someone trained to inspect scaffolding according to OSHA regulations.

The Three Main Colors and What They Mean
Just like traffic lights, scaffold tags come in a standard color system to make the safety status clear at a glance:

? Green Scaffold Tag — SAFE FOR USE
Meaning: The scaffold has been inspected and is safe for use.

Use: Indicates the scaffold meets all safety requirements and can be used by authorized personnel.

Bonus Tip: Always double-check that a green tag includes the date and inspector’s initials. An undated tag is as good as no tag.

? Yellow Scaffold Tag — CAUTION / MODIFIED USE
Meaning: The scaffold may be partially incomplete, under construction, or limited.

Use: Access is restricted, and special instructions will be listed (e.g., “Fall protection required” or “Do not use top platform”).

Did You Know? In some systems, yellow tags are used for incomplete scaffolds still under assembly, but this varies by company policy.

? Red Scaffold Tag — DO NOT USE
Meaning: The scaffold is unsafe and must not be used.

Use: May indicate damage, missing components, or failure to meet inspection standards.

Safety First: If you see a red tag, walk away—immediately notify your supervisor or safety officer.

Optional Colors and Custom Tags

Some companies or job sites also use additional tags for more detailed tracking:

Blue Tags: May indicate scaffolds for special use (e.g., suspended scaffolding).

White Tags: Sometimes used for training or demo purposes.

Orange Tags: Occasionally used for temporary lockout or repair notices.

These colors aren't universal, so always follow your site-specific color chart or tagging system.

How Often Should Scaffold Tags Be Checked?

Scaffolds should be inspected:

Before first use

After any modification or weather event

At least once per shift if in continuous use.

Updating the tag after each inspection ensures the latest safety info is clearly visible.

A Bit of Scaffold Tag Trivia ?

The scaffold tagging system became popular in the U.S. following increased OSHA regulations in the 1990s. It was inspired by similar safety tagging systems used in the UK and Australia.

The “traffic light” tag system mirrors color codes found in other industries, including food safety, equipment lockout/tagout (LOTO), and hospital triage.

Some advanced digital scaffold tags now include QR codes that link to inspection reports, photos, or real-time safety data.
