What “Sample Warning Labels” Mean in Chemical Safety

Sample warning labels are examples of compliant labels used on chemical containers to communicate hazards quickly and consistently. In a chemical safety program, labels are not “nice-to-have”—they are a core control that helps prevent exposures, fires, incompatible mixing, and other incidents.

In the U.S., chemical labeling requirements largely flow from OSHA’s Hazard Communication Standard (HCS), 29 CFR 1910.1200. OSHA aligned the HCS with the Globally Harmonized System (GHS), which standardizes hazard classes, signal words, pictograms, and precautionary statements.

When teams ask for a warning label template, they’re usually trying to solve one of these problems:

  • Creating consistent labels for secondary containers (spray bottles, smaller jugs, application containers)
  • Replacing damaged or illegible labels
  • Standardizing labels across multiple sites or crews
  • Training employees with clear, repeatable examples

A good template helps—but it must match the hazards in the Safety Data Sheet (SDS) for the specific chemical.

OSHA Rules You Need to Know (Before You Copy a Template)

OSHA requires chemical hazard information to be communicated through labels and Safety Data Sheets, supported by employee training. Two OSHA HCS areas are especially relevant when using sample labels.

Shipped Container Labels (GHS-Style Elements)

Under 29 CFR 1910.1200(f), shipped containers must be labeled with the required GHS elements. While OSHA’s label rule is detailed, the common required components include:

  • Product identifier (matches the SDS)
  • Signal word (Danger/Warning) when applicable
  • Hazard statement(s) (standardized phrases)
  • Pictogram(s) (GHS symbols in a red diamond)
  • Precautionary statement(s) (prevention/response/storage/disposal)
  • Name, address, and telephone number of the responsible party

These are not optional “design choices.” If you’re using a warning label template to create shipped-container-equivalent labels for workplace containers, these elements are the safe starting point.

Workplace/Secondary Container Labels

OSHA allows some flexibility for workplace labeling. For example, under 29 CFR 1910.1200(f)(6), employers may use alternative labeling systems on workplace containers as long as the information is consistent with the HCS and employees are trained to understand it.

That said, relying on minimal text (e.g., only “CAUTION”) is a common gap. A strong workplace label—especially where multiple chemicals are in use—should still identify the chemical and clearly communicate hazards.

If a container will be used by more than one person, across shifts, or stored for later use, treat it as a “real” labeled container—don’t rely on memory or tribal knowledge.

What a Good Warning Label Template Should Include

A warning label template helps standardize format, but the content must be pulled from the SDS (especially Sections 1, 2, 4, 7, and 8). The best templates are designed to prevent omissions.

Core Elements to Build Into Your Template

Use these fields on every label:

  • Product Identifier (exact name on the SDS)
  • Supplier/Manufacturer (or internal contact if relabeled in-house)
  • GHS Signal Word (if applicable)
  • GHS Pictograms (as required by hazard classification)
  • Hazard Statements (e.g., “Causes skin irritation”)
  • Precautionary Statements (e.g., “Wear protective gloves/eye protection”)
  • First Aid Quick Notes (brief, referencing SDS Section 4)
  • Storage/Compatibility Notes (brief, referencing SDS Section 7)

Optional—but often useful—fields:

  • NFPA 704 diamond (only if your program uses it consistently)
  • PPE icons aligned with your workplace assessment
  • Location/department (helps inventory control and emergency response)

Sample Warning Labels (Examples You Can Adapt)

These sample warning labels show common formats. They are examples only—always verify hazard statements, pictograms, and precautionary text against the current SDS.

Sample 1: Flammable Liquid (e.g., Acetone)

Product Identifier: Acetone

Signal Word: Danger

Pictograms: Flame, Exclamation Mark (as applicable)

Hazard Statements:

  • Highly flammable liquid and vapor
  • Causes serious eye irritation
  • May cause drowsiness or dizziness

Precautionary Statements:

  • Keep away from heat/sparks/open flames/hot surfaces—No smoking
  • Keep container tightly closed
  • Use only outdoors or in a well-ventilated area
  • Wear protective gloves/eye protection

First Aid (Brief): If in eyes: Rinse cautiously with water for several minutes. Get medical attention if irritation persists.

Sample 2: Corrosive Cleaner (e.g., Sodium Hydroxide Solution)

Product Identifier: Sodium Hydroxide Solution

Signal Word: Danger

Pictograms: Corrosion

Hazard Statements:

  • Causes severe skin burns and eye damage
  • May be corrosive to metals

Precautionary Statements:

  • Do not breathe mist/vapors
  • Wash hands thoroughly after handling
  • Wear protective gloves/protective clothing/eye protection/face protection
  • Store locked up; store in corrosion-resistant container

First Aid (Brief): If on skin: Take off immediately all contaminated clothing. Rinse skin with water/shower.

Sample 3: Compressed Gas (e.g., Nitrogen)

Product Identifier: Nitrogen, Compressed

Signal Word: Warning (varies by classification)

Pictograms: Gas Cylinder

Hazard Statements:

  • Contains gas under pressure; may explode if heated
  • May displace oxygen and cause rapid suffocation

Precautionary Statements:

  • Protect from sunlight; store in a well-ventilated place
  • Secure cylinders upright; keep valve protection cap in place when not in use

First Aid (Brief): If inhaled: Remove person to fresh air and keep comfortable for breathing.

Common Labeling Mistakes (and How to Avoid Them)

Even with a template, errors happen. The following gaps show up frequently in audits and incident investigations:

  • Using a generic warning (e.g., “Caution”) without identifying the chemical and hazards
  • Mismatching names between the label and SDS (product identifier must align)
  • Missing pictograms/signal word on labels intended to mirror GHS shipped-container elements
  • Handwritten labels that fade or smear (especially around solvents and wash-down areas)
  • Outdated SDS data (label reflects an older formulation or revision)
  • No training on the labeling system (required under 29 CFR 1910.1200(h))

A good practice is to standardize label creation and tie it to SDS revision control.

How SwiftSDS Helps You Create Consistent, Compliant Labels

Managing labels is hard when SDSs are scattered across email threads, binders, and shared drives. SwiftSDS helps by centralizing your SDS program and making it easier to build accurate labels based on current information.

With SwiftSDS, you can:

  • Maintain a centralized SDS library so label writers are always referencing the latest SDS
  • Support OSHA HCS compliance (29 CFR 1910.1200) by improving access to hazard information and standardizing processes
  • Align labels with GHS classification and pictograms through consistent SDS data visibility
  • Pair labeling with chemical inventory management, so you know what’s on site, where it is, and which containers need workplace labels
  • Enable mobile access, allowing workers and supervisors to verify hazards and SDS details on the spot—critical when relabeling secondary containers

If you’re building a warning label template for multiple departments or locations, centralized SDS control and quick retrieval are the difference between “looks right” and “is right.”

Best Practices for Implementing a Warning Label Template

To keep templates practical and audit-ready, integrate them into your HazCom workflow:

  1. Define when secondary container labeling is required (single-user immediate-use containers vs. stored/shared containers).
  2. Standardize the template fields (product identifier, hazards, precautions, pictograms).
  3. Assign responsibility (who creates, prints, applies, and inspects labels).
  4. Train employees to understand label elements and how they relate to SDS content (OSHA 1910.1200(h)).
  5. Audit routinely: check for missing labels, damaged labels, and mismatches with the SDS.

A template improves consistency, but your SDS process ensures accuracy. Treat labeling and SDS management as one system.

Call to Action

If you’re using sample warning labels to build a safer workplace, make sure your labels stay aligned with the most current SDS and OSHA’s HazCom requirements. SwiftSDS makes it easier to centralize SDS access, support GHS-aligned labeling, and manage chemical inventory across your sites.
