What Is a Safety Data Sheet Sign (and Why It Matters)

A safety data sheet sign is workplace signage that directs employees to the location of Safety Data Sheets (SDS) and reminds them how to access chemical hazard information. You’ll also hear these called SDS signs or, using older terminology, MSDS signs (Material Safety Data Sheets). While the document name changed from MSDS to SDS under GHS-aligned updates, the goal hasn’t changed: make hazard information easy to find, immediately.

Under OSHA’s Hazard Communication Standard (HazCom), 29 CFR 1910.1200, employers must ensure employees have ready access to SDSs for hazardous chemicals in the workplace. Signs aren’t explicitly mandated by OSHA in every situation, but they are a practical and widely used control to support compliance—especially in larger facilities, multi-shift operations, or worksites with multiple chemical storage areas.

If an employee can’t quickly locate SDS information during normal work hours (or an emergency), your program may not meet OSHA’s “readily accessible” expectation.

OSHA SDS Regulations That Influence SDS Signage

To understand why SDS signage is so important, it helps to tie it to the HazCom requirements that drive SDS access and training.

OSHA 29 CFR 1910.1200: SDS access must be “readily accessible”

OSHA requires that employers maintain SDSs for hazardous chemicals and ensure they are readily accessible to employees when they are in their work areas during each work shift.

In practice, “readily accessible” means:

  • Employees can get the SDS without barriers (no locked office, no manager-only access)
  • Access works across all shifts, including nights/weekends
  • Access isn’t dependent on one person being present
  • Employees know where and how to access SDSs

A clearly placed safety data sheet sign supports this requirement by eliminating confusion and reducing time-to-access.

Training obligations: workers must know where SDSs are

HazCom also requires employers to provide effective training on hazardous chemicals, including how to read labels and SDSs and how employees can obtain hazard information. If your training says “SDS binder is in the maintenance office,” but the binder is moved (or the office is locked), you have a gap.

SDS signs help reinforce training by providing a consistent, visible reference point.

SDS Signs vs. MSDS Signs: Does the Wording Matter?

Many workplaces still use MSDS signs because their older binders and procedures haven’t been updated. OSHA’s HazCom standard has aligned with GHS and uses “SDS” terminology, so updating signage is a smart housekeeping move.

That said:

  • Using “MSDS” signage doesn’t automatically mean noncompliance
  • Confusion can happen for new hires or contractors trained on “SDS” terminology
  • Mixed terminology can slow access during an emergency

Best practice is to transition to SDS signs (or use signage that references both, such as “SDS/MSDS Location”) during the changeover.

Where to Post SDS Signs for Real-World Compliance

A safety data sheet sign is only useful if it is posted where people actually need it. OSHA inspections often focus on whether employees can demonstrate access quickly—not just whether you “have SDSs somewhere.”

Common effective locations

Place SDS signs where they naturally fit into workflow and emergency response:

  • Near chemical receiving and storage areas
  • At entrances to production floors where chemicals are used
  • By maintenance shops and janitorial/cleaning supply rooms
  • In laboratories, paint rooms, and mixing areas
  • Near eyewash stations or first-aid stations (when relevant)
  • Next to SDS binders, kiosks, or QR-code access points

Multi-location and multi-shift considerations

If your facility has multiple buildings, remote job sites, or rotating crews, a single binder in one office can create access barriers. In these environments, signage should point employees to:

  • The nearest SDS access point for that work area
  • A digital SDS method (tablet station, intranet page, or approved mobile access)

What Should an SDS Sign Include?

While OSHA doesn’t prescribe a single required format for SDS signage, strong signs share the same core elements: clarity, durability, and immediate direction.

Recommended content for SDS signs

Include:

  • “Safety Data Sheets (SDS) Location” as the primary header
  • Exact location details (e.g., “Binder on wall next to time clock”)
  • Instructions for digital access if used (e.g., “Scan QR code” or “Open SwiftSDS on tablet”)
  • A backup access method (e.g., “If system is down, contact supervisor or EHS”)—without making access supervisor-dependent
  • Optional: emergency reminders such as “Bring SDS to medical provider” when appropriate

Keep it readable and durable

SDS signs should be:

  • Large enough to read at a distance
  • Posted at eye level and unobstructed
  • Printed on durable material in wet/dirty environments
  • Updated promptly if SDS access points change

Digital SDS Access: How Signs Support Modern Compliance

Many organizations are moving from binders to digital SDS systems because they simplify updates and improve access. OSHA allows electronic SDS management as long as employees have no barriers to access.

Digital systems often fail compliance expectations when:

  • Devices are locked behind passwords that employees don’t have
  • Wi-Fi is unreliable in production areas
  • Only one computer terminal exists and it’s not near the work area

A well-designed safety data sheet sign can solve part of this by providing:

  • Clear instructions for access (QR codes, short URLs, or device location)
  • Consistent messaging across departments
  • Visual reinforcement of where to go in an emergency

This is where SwiftSDS fits naturally. SwiftSDS provides a centralized, cloud-based SDS library with mobile access, making it easier to ensure SDSs are available across shifts and locations. When you pair SwiftSDS with strong SDS signage (e.g., “Scan here to access SDSs in SwiftSDS”), employees can retrieve documents quickly without hunting for a binder.

You can also strengthen your program by linking signage to your broader HazCom system—chemical inventory by location, expiration tracking, and standardized access across all departments.

Common SDS Sign Mistakes (and How to Fix Them)

Even well-intentioned facilities can weaken their HazCom program with signage missteps.

Mistake 1: The sign points to an outdated binder

Fix:

  • Audit SDS access points quarterly (or whenever chemicals/processes change)
  • Update signs immediately after relocating binders or devices

Mistake 2: The SDS location is locked or restricted

Fix:

  • Relocate binders to accessible areas
  • Provide open-access kiosks or tablets for digital SDS
  • Ensure employees can access SwiftSDS (or your SDS platform) without delays

Mistake 3: Inconsistent terms (MSDS vs. SDS)

Fix:

  • Standardize on “SDS” in training and signage
  • Use temporary dual-language signs during transitions

Mistake 4: Employees don’t know what the sign means

Fix:

  1. Reinforce signage meaning during HazCom onboarding
  2. Include “Find the SDS sign” as part of job-specific training
  3. Conduct quick spot checks: ask employees to show how they would find an SDS

Choosing SDS Signs That Support Inspections and Safety Culture

From an inspection-readiness standpoint, SDS signs should help employees demonstrate compliance confidently. Ask yourself:

  • Can a new employee find an SDS in under 1 minute using the sign?
  • Are signs present in every work area where hazardous chemicals are used?
  • Do your signs match your current process (binder, kiosk, or mobile)?

If you’re standardizing across multiple sites, document your signage approach in your HazCom plan and keep it consistent.

Call to Action: Make SDS Access Obvious, Fast, and Audit-Ready

A safety data sheet sign is a simple tool that supports a big requirement: ensuring SDSs are truly “readily accessible” under OSHA 29 CFR 1910.1200. Clear SDS signs (and updated replacements for older MSDS signs) reduce confusion, reinforce training, and help employees get hazard information when seconds matter.

If you’re ready to modernize SDS access, SwiftSDS can help you centralize your SDS library, support GHS-aligned documentation, and enable mobile access across departments and job sites.
