How to Run a Hazard Communication Review in 30 Minutes

This guide is for EHS managers, supervisors, and site leaders in plants, warehouses, laboratories, and maintenance shops. OSHA's Hazard Communication Standard, 29 CFR 1910.1200, aligns with GHS, which means the site must make chemical hazards visible through labels, safety data sheets, and training. HSE guidance says SDS help people handle chemicals safely, although the form only works when the container, the task, and the worker understanding match the job.

Across 25+ years leading EHS at multinationals, Andreza Araujo has seen that hazard communication fails when the chemical list lives in one system and the work happens in another. As Andreza Araujo argues in Safety Culture: From Theory to Practice, culture shows up in repeated decisions. A Ilusao da Conformidade is relevant here because a site can look compliant on the shelf while no one can explain the hazard at the point of use.

The thesis is simple. A hazard communication review should end with a clearer decision about storage, transfer, translation, labeling, and emergency response, not with a signed folder.

What you need before starting

Choose one work area, one shift, and one chemical flow. A useful review starts with the place where people store, open, pour, mix, clean, or dispose of the product. Use the chemical inventory audit as your starting point, then decide whether the task is routine or occasional, because the review must match the actual exposure pattern.

Agree who will join the walk. One supervisor, one worker from the area, one EHS person, and one person who understands storage or purchasing is enough. The common error is to review hazard communication with no one who actually moves the chemicals. Across more than 250 cultural transformation projects, Andreza Araujo has seen that controls drift when the review team never sees the task.

If the area already uses decanting, secondary containers, or contractor products, pull those items into the same review. A review that only checks the main drum will miss the spray bottle, the returnable tote, or the wash chemical that changed during the last purchase cycle.

Step 1: Collect the chemical list by area

Start with the real list of products in the work area, not the purchasing catalog. Walk the room, the cabinet, the cage, and the maintenance cart, then record each product name, container type, and approximate quantity. If the chemical is in a secondary container or an unlabeled bottle, add it to the list because that is where hazard communication often collapses.

The verification question is simple. Can the supervisor name every product in the area without checking a desk file? If the answer is no, the list is already too weak for field use. The common error is to trust a centralized spreadsheet that has not been reconciled with what workers actually handle.

Use the review to find duplicate products, obsolete products, and products stored in the wrong room. If the site has not reconciled its inventory for months, the problem is not only chemical control. It is also control ownership, because nobody is responsible for removing what the site no longer needs.

Step 2: Match each item to the SDS and label

For each product, check the product identifier on the container against the identifier on the SDS. Then check that the label, signal word, hazard statements, precautionary statements, and pictograms match the same product. A hazard communication review that skips this cross-check can look tidy while still hiding a wrong bottle or a stale SDS.

Do not accept a file that is only stored in the office. The worker should be able to reach the SDS at the point of use or through a system that really works on the floor. If the product name on the bottle differs from the name on the SDS, stop and fix the mismatch before the next task begins.

This step is where Andreza Araujo's Safety Culture: From Theory to Practice becomes practical, because culture is visible in whether the supervisor pauses for a mismatch or waves it through to save time.

Step 3: Check the hazard words that workers must see

Open the label and ask whether a worker can understand what kind of harm the product can cause. If the signal word, pictograms, and hazard statements do not match the task, the label is too weak for field decisions. Use the GHS pictograms guide as a visual check only after the product identity has been confirmed.

The common error is to treat pictograms like decoration. A skull-and-crossbones, an exclamation mark, or a corrosion symbol only helps when the supervisor can connect it to exposure, contact, storage, and emergency response. If the team cannot explain what the label means in plain language, the communication loop is not closed.

Do not overload this step with training theory. The review only needs to prove that the label says the same thing the task requires. If the site uses different languages, the label and the local explanation must both be understandable to the workforce.

Step 4: Walk the storage and transfer points

Move to the actual storage and transfer points, because the label review is incomplete until you see the container in its real place. Check whether incompatible products are separated, whether lids close properly, whether funnels and pumps are clean, and whether secondary containers are still legible after repeated use. The field is where hazard communication either survives or fails.

Look for decanting, mixing, dilution, and waste collection points. Those are the places where people most often lose the label, spill the product, or assume that a small container does not need the same discipline as the original package. If a spray bottle or cup has no durable identification, it must be corrected before the next shift repeats the same ambiguity.

Link this walk with the emergency eyewash stations review when the chemicals can splash the face or eyes. A communication review is weak if the site knows the hazard words but does not know where the first response equipment sits.

Step 5: Test worker understanding with live questions

Ask the worker three live questions. What is the product, what does it do, and what is the first response if the product contacts skin, eyes, or breathing space? The goal is not to quiz people for sport. The goal is to see whether the communication reaches the person who will actually use the product at 6 a.m. or 11 p.m.

If the worker can only answer by pointing at a cabinet or a poster, the review is incomplete. Ask where the SDS is, who can explain it on the shift, and whether the worker knows which part of the label matters most for the specific task. In more than 250 cultural transformation projects, Andreza Araujo has observed that understanding improves when the supervisor turns the label into a decision, not when the site adds another wall poster.

The common error is to mistake recognition for understanding. A worker may recognize the color of the bottle and still not know the splash hazard, the inhalation risk, or the correct first response. A useful hazard communication review catches that gap before it becomes an incident.

Step 6: Check language, literacy, and contractor access

Review whether the chemical information is understandable to everyone who uses the product. That includes new workers, contractors, temporary staff, and people who speak a different first language. If the product is shared across shifts or vendors, the site needs a communication method that travels with the work and not only with the permanent staff.

Do not assume that a translated SDS alone solves the problem. The supervisor still needs a short field explanation that matches the local task and the local emergency response. As Andreza Araujo notes in A Ilusao da Conformidade, the appearance of compliance can hide a deeper access problem when the people exposed to the chemical cannot actually use the information.

If contractors bring their own products, make access to the site rule explicit before the work starts. The review should verify who approved the product, who checked the label, and who owns the SDS copy on site. If no one can answer that, the contractor interface is weaker than the chemical program needs.

Step 7: Close the emergency gap

Now test the emergency side of the review. If the product splashes, leaks, or fumes, can the worker reach eyewash, shower, spill kit, alarm, and first aid without guessing? The communication review should tie the hazard words to the response path, because a label without an emergency route is only half of a control.

Use the emergency walk to check whether the response equipment is visible, reachable, and inspected. If the first response depends on memory alone, the site has turned a chemical control into a hope statement. The Hazard Communication: 7 Controls Before SDS Fail article gives the wider control view behind this review.

The common error is to assume that an eyewash or shower on the drawing is good enough. A good review asks how long it takes to reach the equipment, whether the route is blocked, and whether the worker knows the first action before help arrives.

Step 8: Turn the review into 30-day actions and verification

Close the review by assigning owners, dates, and proof of completion. If the label is missing, replace it. If the SDS is wrong, update it. If the bottle is unidentified, relabel or remove it. If the worker cannot explain the hazard, fix the explanation and test it again. A good review changes the next shift, not just the next file.

Use a 30-day follow-up list with one owner per issue and one field check per fix. This is the point where Andreza Araujo's Safety Culture Diagnosis: Learn how to do your own becomes useful, because the review can move from perception to evidence only when the site checks whether the control actually works in the task.

If the same mismatch appears twice, escalate it to management review. Repeated label problems, stale SDS files, or unlabeled secondary containers are not clerical defects. They are signs that the control system is not keeping pace with the work.

Final checklist

• One area, one shift, and one chemical flow were reviewed against the real task.
• Every product was matched to its SDS, label, signal word, and hazard statements.
• Secondary containers, decanting points, and contractor products were checked in the field.
• Workers could explain the product, the main hazard, and the first response in plain language.
• Language access, eyewash, shower, spill response, and ownership were verified before the review closed.

FAQ

What is a hazard communication review?

A hazard communication review checks whether the chemical list, SDS, labels, pictograms, worker understanding, storage, and emergency response all point to the same reality. It is more than a document check because it tests whether the information is usable at the point of work.

How long should the review take?

For one area, a focused review can be done in about 30 minutes if the team stays on the floor and checks only the live products, the SDS, the labels, and the response path. More complex areas need more time, especially when contractors, multiple languages, or transfer points are involved.

Do labels alone satisfy hazard communication?

No. Labels are necessary, but they do not replace the SDS, worker understanding, compatible storage, emergency equipment, or supervisor verification. A label that looks correct while the container or task is wrong does not control the exposure.

When should the review be repeated?

Repeat the review when a new product arrives, a container changes, a contractor brings chemicals, a worker group changes, or an incident shows that the communication did not reach the floor. Repeating it after a major change is more useful than waiting for an annual document cycle.

What should leaders do if the review finds the same problem again?

Leaders should treat repeat label or SDS problems as a control failure, not as housekeeping. Escalate the issue, assign a named owner, and verify the fix in the field. If the problem keeps coming back, the site needs a broader diagnostic of control ownership and supervision.
