The short answer

The GHS Safety test is a 10-minute, 15-question multiple-choice assessment for intermediate roles that handle hazardous chemicals. Candidates interpret GHS labels and safety data sheet excerpts, then apply them to safe handling, storage, moving, disposal, and spill or exposure response. It suits production, plant, warehouse, laboratory, maintenance, cleaning, and facilities teams.

What it measures

Reading GHS labels and safety data sheets, and applying them to safe handling, storage, disposal and emergency response.

Reading labels and safety data sheets

Candidates interpret hazard information from GHS labels and safety data sheet excerpts.

Safe work with hazardous chemicals

Questions ask candidates to apply chemical hazard information to safe work actions.

Storage, moving and disposal

Candidates use the information provided to decide how to store, move, or dispose of a chemical.

Responding to spills and exposures

Candidates choose what to do after a chemical spill or exposure in a workplace scene.

Question formats

Multiple choice

The candidate: Reads a short situation, table or statement and picks the right answer, or every right answer.

You see: Whether the candidate knows the material well enough to apply it, not just recognize it.

15 questions in 10 minutes, served one at a time.

Roles this test fits

Production and process operators, plant and warehouse workers, laboratory and maintenance technicians, cleaning and facilities staff, and other roles that handle hazardous chemicals at work.

What this test can show

Apply label information
See whether candidates can use GHS label and safety data sheet details to identify hazards and choose safe handling actions.
See the next step after a spill
Scenes show a spill or an exposure and ask what to do first, so you see how a candidate would act when something goes wrong with a chemical.
Use shared reference information
Each question includes the label, data sheet excerpt, or site rule it relies on, and uses plain wording with pictograms described by symbol.

Test integrity signals

Each candidate receives a different question set, order, and arrangement of answer options. The browser shows one question at a time, and answer keys stay on HireValid’s servers. The 10-minute timer runs on the server; reloading returns the same question with only the remaining time. Candidates cannot copy or select question text, and blocked copy attempts are recorded. Each personal invitation link expires, and a finished test cannot be taken again. HireValid records signals such as time away from the test tab, pastes into answers, and answers given faster than a question can be read. An Integrity Score and evidence timeline are provided for the employer to review; the system does not decide on its own. See how we build our tests.

How we prevent AI cheating · Integrity signals

Use the score as evidence

Review the result alongside a job-related work sample and a structured interview. For example, ask candidates to interpret a provided label or data sheet excerpt, then explain their choices. Treat the score as evidence for a person to review, not as a decision by itself. The pre-employment testing guide offers more context on using hiring tests.

Structured interview questions

How would you use the information on this label to decide what precautions to take before handling the chemical?
Listen for a clear link between the hazard information provided and the candidate’s proposed safe work actions.
Imagine a chemical spills in the work area. How would you respond using the site rule provided?
Listen for a reasoned response that uses the given site rule and addresses the spill situation.
How would you decide where to store this chemical using the data sheet excerpt?
Listen for the candidate to find relevant information in the excerpt and explain how it informs storage.

Understand scoring and benchmarks

Fairness and accommodations

Every question gives the label, data sheet excerpt or site rule it relies on, so answers rest on the GHS elements shared across countries rather than any one country's law. Pictograms are described by their symbol, never by color alone, and the wording is kept plain for readers whose first language is not English. Names and workplaces vary, and no question involves money, idioms or local knowledge. The test checks knowledge and does not replace a site's own chemical safety training.

You can give any candidate extra time as an accommodation. Results are evidence for a person to review, never an automatic decision.

Provisional: reliability is reported once 200 candidates have completed it.

Test details

A short, timed check of how well a candidate reads GHS hazard labels and safety data sheets and turns what they say into safe action on the job. Questions show labels, data sheet excerpts and workplace scenes, and ask what the hazard is, how to handle, store, move or dispose of the chemical, and what to do after a spill or exposure.

Questions are in English.
No aids are needed.
Each question is answered once, in order, with no going back.
