Precautionary statements on a container label: what OSHA expects

A precautionary statement on a container label tells workers what to do to prevent or minimize adverse effects from exposure to a hazardous chemical. Under OSHA’s Hazard Communication Standard (HCS), 29 CFR 1910.1200, chemical manufacturers and importers must classify hazards and communicate them on labels and Safety Data Sheets (SDSs). Employers must ensure labels on shipped containers remain intact and legible and that workplace labeling supports safe use.

Precautionary statements are part of the GHS-aligned label elements required by OSHA for shipped containers. They work together with the signal word, hazard statements, and pictograms to provide clear, actionable instructions for safe handling.

A label isn’t just a warning—it’s a short, task-focused set of instructions designed to prevent injuries, illnesses, fires, and releases.

Where precautionary statements fit in OSHA HazCom labels

OSHA’s HCS requires shipped container labels to include specific elements (see 29 CFR 1910.1200(f)). These include:

  • Product identifier
  • Signal word
  • Hazard statement(s)
  • Pictogram(s)
  • Precautionary statement(s)
  • Name, address, and telephone number of the responsible party

In other words, if you’re wondering what a “precautionary statement on a container label” is in the context of HazCom: it’s a required label element that communicates recommended measures to reduce risk.

“Danger and warning are examples of” what?

In GHS/OSHA labeling, “Danger” and “Warning” are examples of signal words. They indicate relative severity:

  • Danger = more severe hazards
  • Warning = less severe hazards

Signal words and precautionary statements serve different purposes. The signal word grabs attention; the precautionary statements tell workers what actions to take.

Understanding GHS P statements (precautionary statements)

You’ll often hear precautionary statements called GHS P statements. Under GHS conventions (which OSHA largely follows), each precautionary statement is associated with a standardized code beginning with “P” (for example, P280).

Even though workers typically see the plain language on the label (not the code), safety and EHS teams frequently use the code system to standardize labeling and training across sites.

The four main types of precautionary statements

GHS P statements generally fall into four categories:

  • Prevention (reduce exposure or improper handling)
  • Response (what to do in an emergency or if exposure occurs)
  • Storage (conditions for safe storage)
  • Disposal (proper waste handling)

A single chemical may require multiple statements across these categories.

Examples of common GHS P statements

Here are examples of how ghs p statements appear on labels (wording can vary depending on hazard class and required combinations):

  • Prevention: “Wear protective gloves/protective clothing/eye protection/face protection.” (P280)
  • Prevention: “Keep away from heat/sparks/open flames/hot surfaces. — No smoking.” (P210)
  • Response: “IF IN EYES: Rinse cautiously with water for several minutes…” (P305+P351+P338)
  • Storage: “Store in a well-ventilated place. Keep container tightly closed.” (P403+P233)
  • Disposal: “Dispose of contents/container in accordance with local/regional/national/international regulations.” (P501)

The key is that precautionary statements are action-oriented. They should answer: “What do I do to work with this safely?”

Shipped container labels vs. workplace labels: what employers must do

OSHA distinguishes between shipped container labeling and workplace labeling.

Shipped containers (from manufacturer/importer)

Under 29 CFR 1910.1200(f)(1), manufacturers and importers must label shipped containers with the required GHS-aligned elements, including precautionary statements.

Employers must ensure these labels are not removed or defaced and remain legible (see 29 CFR 1910.1200(f)(9)).

Workplace labels (secondary containers)

For workplace containers (for example, smaller bottles, spray containers, or process containers), employers have flexibility under 29 CFR 1910.1200(f)(6). Workplace labels must provide at least:

  • The product identifier, and
  • General information about the hazards (e.g., words, pictures, symbols, or a combination)

However, many organizations choose to align workplace labels with shipped container labels—including precautionary statements—because it reduces confusion and supports training.

Best practice: Make precautionary statements readily available wherever chemicals are used, including on secondary labels when feasible.

Why the “precautionary statement on a container label” matters in real work

Precautionary statements are one of the most practical label elements because they translate hazard classification into worker actions. They can directly influence:

  • PPE selection (gloves, eye protection, respiratory protection)
  • Safe storage (segregation, ventilation, ignition control)
  • Spill response (containment, cleanup methods, first aid)
  • Routine handling behaviors (avoiding breathing vapors, washing hands, avoiding contamination)

Common compliance pitfalls

Even strong HazCom programs can stumble here:

  • Missing or incomplete precautionary statements on shipped labels (supplier issue that still affects the employer’s workplace)
  • Decanted chemicals with no meaningful workplace label
  • Labels that don’t match the current SDS revision
  • Workers trained on “what the chemical is,” but not on what the label is telling them to do

OSHA also requires employee information and training at the time of initial assignment and when new hazards are introduced (see 29 CFR 1910.1200(h)). Training should include how to read labels and understand precautionary statements.

Connecting labels to SDSs for a complete HazCom program

Labels are brief by design. The SDS provides the expanded details that back up the precautionary statements—particularly in:

  • Section 2 (Hazard(s) identification): label elements including precautionary statements
  • Section 4 (First-aid measures)
  • Section 7 (Handling and storage)
  • Section 8 (Exposure controls/personal protection)
  • Section 13 (Disposal considerations)

When your label and SDS are aligned, workers get consistent guidance from the moment they pick up a container through cleanup and disposal.

How SwiftSDS helps keep precautionary statements and SDS access aligned

Managing label information across multiple sites, suppliers, and chemical versions can be challenging—especially when SDS revisions change the recommended controls. SwiftSDS helps solve these SDS management challenges by providing:

  • A centralized SDS library so teams can quickly verify the latest SDS and label elements
  • Support for OSHA HazCom (29 CFR 1910.1200) documentation and readiness
  • GHS support to keep hazard classifications and label elements organized
  • chemical inventory management to track where chemicals are used (so labeling and training can be targeted)
  • mobile access so employees can pull up SDS details instantly when a precautionary statement prompts a question (e.g., “What gloves are recommended?”)

For multi-location employers, this reduces the risk of outdated SDSs, inconsistent labeling practices, and gaps in employee access.

Practical steps to improve precautionary statement compliance

Use these steps to strengthen how precautionary statements are used in your HazCom program:

  1. Verify shipped container labels on receipt (presence, legibility, and consistency with the SDS).
  2. Standardize secondary container labeling in a way workers can understand quickly (many employers mirror GHS elements, including precautionary statements).
  3. Train employees to connect label elements to actions: PPE, handling, storage, and emergency response (per 1910.1200(h)).
  4. Audit for decanted/temporary containers that lack hazard information.
  5. Ensure rapid SDS access so workers can expand on label directions immediately.

If you’re building your program documentation, consider creating a written labeling procedure and linking it to your SDS access method. You can also centralize your approach with tools like SDS Management Software.

Conclusion: precautionary statements turn hazard info into safe behavior

A precautionary statement on a container label is one of the most actionable parts of OSHA HazCom labeling. It tells employees how to prevent exposure, respond to incidents, store chemicals safely, and dispose of them properly. Combined with signal words (remember: danger and warning are examples of signal words) and supported by accessible SDSs, precautionary statements help move compliance from paperwork to day-to-day safe work practices.
