5 real sample questions

Under the Hazard Communication Standard, who is primarily responsible for evaluating a chemical and assigning it a hazard classification?

A. Chemical manufacturers and importers

B. The end-use employer, for every chemical it brings into the workplace

C. Each individual employee who will handle the chemical

D. The retailer that sells the chemical to the employer

Show answer and reasoning

Correct answer: A. Chemical manufacturers and importers

B: Employers rely on manufacturer classification in the ordinary case; the standard does not make every employer re-derive a hazard classification.
C: Individual employees are recipients of hazard information, not the party responsible for classifying chemicals.
D: Retailers distribute hazardous chemicals; classification is a manufacturer/importer responsibility.

The Hazard Communication Standard applies to a hazardous chemical in a workplace under which condition?

A. Where employees may be exposed to it under normal conditions of use or in a foreseeable emergency

B. Only where the chemical is stored in a container larger than 55 gallons

C. Only where the chemical has already caused a documented injury at that workplace

D. Only where the chemical is regulated by the Department of Transportation

Show answer and reasoning

Correct answer: A. Where employees may be exposed to it under normal conditions of use or in a foreseeable emergency

B: Container size is not the trigger for coverage.
C: Coverage does not depend on a chemical having already caused an injury.
D: DOT regulation of a chemical in transport is a separate framework from workplace HazCom coverage.

For laboratories that use hazardous chemicals but do not ship them out, what does the standard require?

A. Preserving labels on incoming containers, keeping SDSs accessible during work shifts, and providing employee information and training

B. Nothing; laboratories are entirely excluded from the standard

C. Full workplace labeling of every container down to the test tube, with no exceptions

D. A separate laboratory-specific SDS format distinct from the standard 16-section format

Show answer and reasoning

Correct answer: A. Preserving labels on incoming containers, keeping SDSs accessible during work shifts, and providing employee information and training

B: Laboratories are covered, just with lab-specific provisions rather than a full exemption.
C: The lab provisions are narrower than full container-by-container workplace labeling.
D: Laboratories use the same 16-section SDS format as any other workplace.

Source: 29 CFR 1910.1200(b)(3)

A warehouse worker only ever moves sealed, unopened containers of a hazardous chemical without ever opening them under normal operating conditions. What does the standard still require for that operation?

A. Preserving container labels, keeping SDSs accessible (or obtainable on request), and training employees on the hazards of a spill or leak

B. Nothing at all, because the containers are never opened

C. A full SDS binder physically bolted to every pallet

D. Individual employee medical surveillance for every worker who touches a sealed container

Show answer and reasoning

Correct answer: A. Preserving container labels, keeping SDSs accessible (or obtainable on request), and training employees on the hazards of a spill or leak

B: The sealed-container provisions still require label preservation, SDS access, and spill/leak training.
C: The standard does not dictate physical placement of an SDS binder, only accessibility.
D: Medical surveillance is not a HazCom requirement at all; it belongs to substance-specific standards.

Which of these products is exempt from the Hazard Communication Standard's labeling requirements because it is already regulated under a different federal labeling scheme?

A. A pesticide labeled under FIFRA

B. An industrial solvent used in a paint shop

C. A cleaning chemical concentrate sold to a janitorial contractor

D. A corrosive chemical used in electroplating

Show answer and reasoning

Correct answer: A. A pesticide labeled under FIFRA

B: An industrial solvent is a typical HazCom-covered chemical, not an exempt product.
C: A cleaning concentrate sold for workplace use remains covered.
D: An electroplating corrosive is a covered workplace chemical.
