What Is an SDS? Safety Data Sheet Standard Explained

What Is a Safety Data Sheet?

A Safety Data Sheet (SDS) is a standardized document that provides critical information about a hazardous chemical — its properties, health and physical hazards, safe handling procedures, storage requirements, and emergency response measures.

Under OSHA's [Hazard Communication Standard](/blog/what-is-hazcom) (29 CFR 1910.1200), every hazardous chemical in your workplace must have an accompanying SDS. It's not optional — it's the law.

Why SDSs Matter

An SDS is more than a compliance checkbox. It's the single most important document for protecting workers who handle chemicals. When a spill happens, when an employee reports symptoms, or when an OSHA inspector walks through the door — the SDS is the first thing everyone reaches for.

Without accurate, accessible SDSs:

• Workers don't know the hazards they're exposed to
• First responders can't treat chemical exposures properly
• Your business is exposed to OSHA citations up to $16,131 per violation
• In the worst case, people get hurt

The 16 Sections of an SDS

Every SDS follows the same GHS-standardized format with 16 sections:

Sections 12–15 are required by GHS but not enforced by OSHA. However, manufacturers typically include them.

How to Read an SDS Quickly

You don't need to read all 16 sections every time. For day-to-day operations, focus on:

• Section 2 — Know the hazards at a glance (pictograms and signal words)
• Section 4 — Know what to do if someone is exposed
• Section 7 — Know how to handle and store the chemical safely
• Section 8 — Know what PPE is required

For emergencies, Section 4 (first aid), Section 5 (fire), and Section 6 (spills) are critical.

Common SDS Mistakes That Get Businesses Cited

1. Missing SDSs — You have a chemical but no SDS on file
2. Outdated SDSs — The manufacturer updated the SDS but you still have the old version
3. Inaccessible SDSs — They're in a binder in a locked office, not where workers can reach them
4. No process for new chemicals — A new product arrives and nobody obtains the SDS before it's used
5. Language barriers — SDSs only available in English when workers speak other languages

Digital SDS Management

Paper binders were the standard for decades, but they create real problems:

• Pages go missing or get damaged
• Updates require manually swapping sheets
• Employees can't access them remotely or on the production floor
• There's no way to search across your entire chemical inventory

Modern SDS management platforms solve these problems. Tellus EHS uses AI to automatically parse SDS documents, extract hazard data, and make your entire chemical library searchable and accessible from any device — so your team always has the right information at the right time.

Getting Started

If you're not sure whether your SDS collection is complete and current, start with a simple audit:

1. Walk your facility and list every chemical product you see
2. Compare that list against your SDS collection
3. Flag any gaps — missing SDSs, outdated versions, or chemicals you didn't know about
4. Set up a system to capture new SDSs before chemicals enter your workplace

The gap between your chemical inventory and your SDS collection is your compliance risk. Close it, and you've solved the most common HazCom citation.
