Hazard Communication
The Wrong Label Sends Workers Into the Wrong Hazard
If the container lies, the crew pays for it
A mislabeled or unlabeled chemical container is a trap: a worker grabs what they think is water and gets acid, or uses a solvent near an ignition source because no pictogram warned them. OSHA's Hazard Communication Standard requires every container to carry accurate GHS information, and OSHA Scan reviews your photos to read labels, flag missing pictograms and signal words, and catch unmarked secondary containers before they cause harm.

What this scenario looks like
Improper chemical labeling is any container of a hazardous chemical that lacks the required GHS information or carries information that is wrong, faded, or contradictory. A compliant label needs the product identifier, signal word, hazard statements, precautionary statements, pictograms, and the supplier identification — all legible and matching the contents.
On real sites this shows up as a spray bottle of degreaser labeled only 'cleaner,' a drum whose original label has weathered to nothing, or a secondary container filled from a bulk supply with no marking at all. It also appears when a container is reused for a different chemical but the old label is left in place, actively misleading anyone who reads it.
The hazard is that workers trust the label. A missing pictogram means no warning about flammability or corrosivity; a wrong label means confident handling of the wrong substance. Because the mistake is baked into the container itself, it travels with the chemical wherever it goes — which is exactly why reading and verifying labels from photos is so effective.

Why this scenario matters
Immediate consequences
A worker relying on a wrong or missing label can be splashed, poisoned, or ignite a flammable without warning. Emergency responders may also apply the wrong treatment or suppression method.
Legal & financial impact
Container labeling failures are among the most common HazCom citations. Serious violations exceed $16,000 each, and repeated labeling gaps across a site can compound into willful penalties past $165,000.
Operational impact
Mislabeled chemicals can shut down chemical operations during an inspection, force a full relabeling effort, and expose weak links between the container, the SDS, and the inventory.
Industry-specific concerns
Painting, cleaning, manufacturing, and maintenance crews constantly transfer chemicals into spray bottles and buckets, making unlabeled secondary containers one of the most persistent labeling problems.
How OSHA Scan detects this hazard
OSHA Scan uses an AI vision model to read the labels in your photos and check them against the standard. It detects missing signal words and pictograms, flags faded or contradictory text, spots unmarked secondary containers, and cites 29 CFR 1910.1200 — so labeling gaps surface during a quick photo review instead of during an exposure.

Real incident case study
An unmarked secondary container of acid
The situation
A maintenance worker decanted a strong descaling acid from a bulk drum into an unlabeled clear bottle to carry it to a cleaning job across the facility. The bottle looked identical to the ones the crew used for water.
What went wrong
A second worker, thirsty and in a hurry, grabbed the bottle believing it was water and splashed acid on his hands and face when he opened it. Without a label, no pictogram or signal word warned him of the corrosive contents.
How OSHA Scan would have prevented it
A photo of the staging bench run through OSHA Scan would have flagged the unlabeled secondary container as a likely HazCom concern, referencing 29 CFR 1910.1200, and prompted the crew to apply a compliant label with the product identifier and corrosive pictogram before the bottle left the area.
Lessons learned
Secondary containers are where labeling quietly fails. Any chemical transferred out of its original packaging must be labeled immediately, and a quick photo audit of work benches catches the unmarked ones before someone trusts the wrong bottle.
Prevention best practices
Layered controls, from most to least effective.
Engineering controls
Design containers and labels so the hazard is always visible and durable.
- Use pre-printed GHS labels with all six required elements for common chemicals
- Apply chemical- and weather-resistant labels that survive the work environment
- Provide labeled, dedicated secondary containers for each transferred chemical
- Color-code storage areas to match hazard classes and reduce mix-ups
Administrative controls
Build labeling into every chemical transfer and inspection routine.
- Require immediate labeling of any secondary container before it leaves the fill point
- Verify each label against the SDS and chemical inventory
- Inspect containers for faded, damaged, or contradictory labels each shift
- Remove or overwrite old labels when a container is repurposed
- Train workers to never use an unlabeled or unclear container
Personal protective equipment
Protect workers who handle and label hazardous chemicals.
- Chemical-resistant gloves suited to the products being transferred
- Splash goggles or a face shield when decanting hazardous liquids
- An apron or chemical-resistant clothing for corrosives
- Inspect PPE before each transfer and replace any degraded gear

Frequently asked questions
What information must be on a GHS chemical label?
A compliant label needs six elements: the product identifier, a signal word (Danger or Warning), hazard statements, precautionary statements, pictograms, and the supplier's name and contact information. All must be legible and match the container's contents and its SDS.
Do secondary containers need labels?
Yes, in almost every case. When a chemical is transferred into a secondary container, it must be labeled with at least the product identifier and hazard information. The only exception is a portable container used immediately by the worker who filled it and emptied within the same shift.
What are the GHS pictograms and what do they mean?
GHS uses standardized red-bordered diamond pictograms for hazards such as flammable, corrosive, toxic, health hazard, oxidizer, and compressed gas. Each communicates a hazard class at a glance so workers can take the right precautions before handling the chemical.
What happens if a label is faded or damaged?
A container whose label is illegible is treated as unlabeled and is a violation. The container must be relabeled with all required GHS information, verified against the SDS, before it is used or moved.
What are the penalties for improper labeling?
A serious labeling violation of 29 CFR 1910.1200 can exceed $16,000 per instance, and repeated or willful labeling failures can climb past $165,000. Labeling is one of the most frequently cited parts of the Hazard Communication Standard.
Can I use my own workplace labeling system?
Employers may use alternative in-house labels for workplace containers as long as they convey the same hazard information, are consistent with the SDS, and workers are trained on the system. Shipped containers from suppliers must carry full GHS labels.
Who is responsible for labeling chemicals on site?
Manufacturers must label shipped containers, and employers must ensure workplace containers — including secondary containers — stay properly labeled. Any worker who transfers a chemical is responsible for labeling the new container immediately.
How accurate is OSHA Scan at detecting labeling problems?
OSHA Scan reads container labels and GHS pictograms, flagging missing signal words, absent pictograms, faded text, and unmarked secondary containers. It cites 29 CFR 1910.1200 so labeling gaps are caught during a routine photo review.

What the AI can and can't detect
OSHA Scan reads a single photo. That makes it fast and easy for anyone on site — but it also means it has real limits. Here's an honest look at both.
What it can catch from a photo
- Missing or incorrect PPE that is visible in the frame
- Unprotected edges, open holes, and visible fall hazards
- Housekeeping, trip, and blocked walkway or exit hazards
- Visible electrical, struck-by, and equipment-guarding hazards
What a photo can't tell it
- Hazards hidden from view or anything outside the photo
- Exact heights, distances, weights, or measurements
- Training records, procedures, or how equipment is actually used
- Full legal compliance or an official OSHA pass/fail determination
OSHA Scan gives an AI-assisted preliminary review from a photo. It does not replace an on-site inspection by a qualified safety professional, and a compliance score is not an official OSHA determination.
