Safety Data Sheet (SDS)
Emergency Number Requirements
Is your company name on a Safety Data Sheet?
OSHA requires an emergency telephone number in Section 1 of every SDS — independent of whether you ship the product.
Your SDS Section 1 must include an emergency telephone number answered by a person with access to emergency response information for the specific chemical. This obligation comes from 29 CFR 1910.1200 Appendix D — OSHA's Hazard Communication Standard — and it applies to any manufacturer, importer, formulator, or private labeler whose name appears on the SDS, regardless of whether the product is shipped. While the standard does not explicitly mandate 24-hour staffing — OSHA's interpretation letters leave hours of operation to the responsible party's judgment — industry best practice and GHS alignment strongly favor round-the-clock coverage, especially for products with acute health or physical hazards. Most companies satisfy it by contracting with a registered third-party emergency response provider.
Who Is Required to Have a Safety Data Sheet?
The SDS obligation under 29 CFR 1910.1200 flows through the chemical supply chain. It begins with the manufacturer or importer and must accompany the product through every commercial transaction to the end employer.
- You manufacture a hazardous chemical and sell or distribute it to employers or other downstream users
- You import a hazardous chemical into the United States for commercial use
- You formulate or blend a hazardous chemical and your company name appears on the label
- You are a private labeler — your brand name appears on a product you did not manufacture
- You distribute hazardous chemicals and no SDS has been provided — you must obtain and pass one through the supply chain
- You are an employer who uses hazardous chemicals — you must obtain, maintain, and make SDSs accessible to employees during their shift
- The substance is not classified as a hazardous chemical under OSHA's criteria (29 CFR 1910.1200(d))
- The product is a consumer product used in the workplace in the same manner and duration as normal consumer use
- The material is a specific exempt category — food, drugs, or cosmetics regulated by FDA for consumer use
- The chemical is an article — a manufactured item that does not release hazardous chemicals under normal conditions of use
Lithium batteries are frequently misclassified as articles and incorrectly excluded from SDS requirements. Under OSHA's definition, an article must not release hazardous materials under normal conditions of use. Lithium batteries do release hazardous materials — electrolyte, toxic gases, and thermal energy — under foreseeable conditions such as damage, short circuit, or overcharge. Manufacturers and importers of lithium batteries are required to prepare and provide a compliant SDS with an emergency phone number in Section 1.
The emergency phone number obligation applies regardless of how you ship the product. A company that sells locally, licenses its brand to a contract manufacturer, or ships under the DOT limited quantity exception is still required to provide a compliant SDS with an emergency number in Section 1. The trigger is whether your company name appears on the SDS as the responsible party.
What Is a Safety Data Sheet and Why Does It Exist?
A Safety Data Sheet is the central document in chemical hazard communication. It is not just a regulatory checkbox — it is the source document that feeds multiple downstream obligations and protects everyone who handles, stores, transports, or responds to an incident involving the chemical.
The SDS is not a standalone document — it is upstream of several other compliance obligations. The proper shipping name and hazard class on your shipping papers must be consistent with the SDS classification. The DOT hazmat label on each package must reflect the hazard class confirmed in the SDS. The employee training required under 49 CFR 172.704 and OSHA 1910.1200(h) is built around the hazard information in the SDS. Getting the SDS right is the foundation everything else rests on.
The 16-section GHS format — Section 1 is where your emergency number lives
OSHA's HazCom 2012 standard aligned with the Globally Harmonized System (GHS). Every SDS must follow the standardized 16-section format in this exact order.
★ EMERGENCY NUMBER
Per 29 CFR 1910.1200 Appendix D, Section 1 must include: (1) product identifier; (2) other means of identification; (3) recommended use and restrictions on use; (4) supplier name, address, and telephone number; and (5) an emergency phone number. The person answering must have access to chemical hazard knowledge — not just a general receptionist. Note: OSHA's interpretation letters (1985, 1986) clarify that the standard does not explicitly mandate 24-hour staffing — hours of operation are left to the responsible party's judgment based on the product's risk profile. However, industry best practice strongly favors 24/7 coverage.
Compliant vs. non-compliant Section 1 emergency numbers
- Answered by a person with access to chemical hazard information for the specific product
- Answered by a person with access to chemical hazard information
- Capable of providing emergency response guidance for the specific product
- A registered third-party emergency response provider covering the product
- A staffed internal chemical emergency line (24-hour coverage recommended)
- Company main line that goes to voicemail after hours
- A customer service number staffed only 9-to-5
- A personal mobile number that may be switched off
- A general answering service without chemical knowledge
- A disconnected or blank number
Most emergency response providers assign a shared pool number to dozens of clients. Hazmat Line works differently — each client receives an exclusive emergency phone number, so your SDS always references a line dedicated to your products and your chemical portfolio. There is no risk of confusion with another company's materials during an incident.
- Exclusive 24-hour emergency phone number — yours alone
- OSHA 29 CFR 1910.1200 compliant for your SDS Section 1
- DOT 49 CFR § 172.604 compliant for your shipping papers
- Year-round regulatory support — not just a phone number
- Hazmat-trained specialists available at any hour
- Transparent annual pricing — no hidden fees, no per-call charges
Most chemical companies have two separate emergency number obligations — OSHA's SDS requirement and DOT's shipping paper requirement (DOT explicitly mandates 24/7 coverage). Hazmat Line satisfies both with a single registered number, eliminating the need to manage two providers or two contracts.
Your dedicated number is yours to print on every SDS and every shipping paper — immediately, from day one.
What Goes Into Creating a Compliant SDS?
Authoring a compliant SDS requires chemical expertise, access to toxicological data, and knowledge of the applicable regulatory framework. It is not a document you can draft from a template without understanding the underlying hazard classification. Below is an overview of what the process involves and the key inputs required.
Every section of the SDS must contain substantive information — OSHA does not accept "not applicable" or blank fields without justification. Section 3 must list all hazardous ingredients above regulatory thresholds. Section 8 must include specific exposure limits and engineering controls. Section 11 must include all available toxicological data. Section 14 must include UN number, proper shipping name, hazard class, and packing group consistent with the DOT Hazardous Materials Table. A deficient section — even if the emergency number in Section 1 is compliant — can still result in an OSHA violation.
A poorly authored SDS that misclassifies the hazard, omits a component, or copies boilerplate language from an unrelated product can expose your company to both OSHA violations and civil liability if a worker or responder is harmed relying on incorrect information. SDS authoring should be done by qualified professionals working from your actual product formulation data.
SDS Compliance Obligations Under 29 CFR 1910.1200
SDS compliance has five distinct obligations. Each applies to a different party in the chemical supply chain — and all must be met for full compliance.
- SDSs must be in English — additional languages are permitted
- Must be accessible without barriers, passwords, or delays
- Backup access procedure required for electronic systems
- Required on every SDS where your company is the responsible party
- Industry best practice: 24/7 coverage — OSHA leaves hours to the responsible party's judgment, but round-the-clock is the safer standard
- Answerer must have access to chemical hazard information for the product
- A registered third-party emergency response provider satisfies this requirement
- Triggered by: new toxicological data, revised classification, new protective measures identified
- Timeline: updated SDS must be ready within 3 months of obtaining the new information
- Updated SDS must be passed forward to all downstream recipients
OSHA SDS Obligation vs. DOT Shipping Paper Obligation
These are two entirely separate legal requirements under two different federal agencies. Most chemical companies are subject to both simultaneously — and the penalties stack independently.
| OSHA — SDS Section 1 | DOT — Shipping Papers | |
|---|---|---|
| Governing standard | 29 CFR 1910.1200, Appendix D | 49 CFR § 172.604 |
| Enforcing agency | OSHA | PHMSA & FMCSA |
| Trigger condition | Company name on SDS as responsible party | Offering hazmat for transport in commerce |
| Applies if you don't ship? | Yes — shipping is irrelevant | No — only when transporting hazmat |
| Where the number appears | Section 1 of the SDS document | On every shipping paper (bill of lading, air waybill, etc.) |
| 24/7 staffing explicitly required? | Not explicitly — hours left to responsible party's judgment (best practice: yes) | Yes — including storage incidental to transport |
| Max penalty per violation | $161,323 (willful/repeat) | $7,500 per shipment |
| Can one number satisfy both? | ✓ Yes — a registered emergency response provider number covers both obligations simultaneously | |
Many companies assume that because they ship under the DOT limited quantity exception — which waives the § 172.604 requirement for ground transport — they have no emergency phone number obligation at all. This is incorrect. The OSHA SDS obligation is entirely independent. If your company name appears on an SDS, the emergency number in Section 1 is required regardless of how or whether you ship.
SDS Requirements for Imported and Exported Products
The GHS is a global framework, but each country adopts it independently — at different revision levels and with country-specific additions. A US-compliant SDS is not automatically compliant in another market, and vice versa.
The US (OSHA HazCom 2012) is aligned with GHS Revision 3. Many other countries have adopted later versions — the EU is on Rev.10, Australia on Rev.7, Japan on Rev.9. This means classification criteria, hazard categories, signal words, and precautionary statements can differ between your US SDS and what the destination country requires. Simply translating a US SDS is not sufficient for export compliance — the document must be reviewed against the destination country's specific GHS adoption and any national deviations.
When a US product is shipped internationally, the emergency phone number in Section 1 must be reachable from the destination country. This means including the full international dialing format (e.g. +1 followed by area code for US-based numbers). A domestic US number without a country code will not work for a first responder calling from Europe or Asia. Hazmat Line provides internationally reachable numbers formatted for use on both domestic and export SDSs.
OSHA Penalties for SDS Non-Compliance
OSHA enforces the Hazard Communication Standard through workplace inspections, complaint-driven investigations, and targeted enforcement programs. Penalties are assessed per violation — and each non-compliant SDS, or each employee without proper SDS access, can constitute a separate citation.
| Violation classification | Description | Penalty range |
|---|---|---|
| Other-than-serious | Minor technical deficiency — direct relationship to safety but unlikely to cause death or serious physical harm | Up to $16,131 |
| Serious | Missing or non-compliant SDS, missing Section 1 emergency number, employees lacking SDS access during shift | $1,037 – $16,131 |
| Willful | Employer knew about the violation and made no reasonable effort to eliminate it | $11,524 – $161,323 |
| Repeat | Substantially similar violation cited within the previous five years | Up to $161,323 |
| Failure to abate | Failure to correct a previously cited violation within the abatement period | Up to $16,131 per day |
A company with 50 products, each with a non-compliant SDS (missing the emergency number or listing a non-compliant line), faces 50 separate serious violations — potential penalty exposure of up to $806,550 from a single OSHA inspection. Companies previously cited and not corrected face willful or repeat classification, pushing the ceiling to $161,323 per SDS.
A single employee complaint about inability to access an SDS, or a report that an emergency number was unanswered during an incident, can trigger a targeted inspection of your entire chemical hazard communication program — including every SDS your company produces or maintains. OSHA does not need to observe a violation first-hand; employee testimony and document review are sufficient.
Industries With the Highest SDS Compliance Exposure
The emergency phone number obligation applies across all sectors that produce, import, or use hazardous chemicals. These industries carry the highest combined OSHA and DOT exposure.
