True
False
Employers must maintain SDSs and ensure employees have access in their work areas at all times. This access is critical for safe handling.
Under the HCS, an environmental hazard pictogram is mandatory on labels in the United States.
True
False
Environmental hazards are part of GHS but are non-mandatory under OSHAs HCS unless a specific federal or state regulation applies.
A label statement reading Fatal if swallowed is an example of a hazard statement under GHS.
False
True
Hazard statements describe the nature and degree of the chemical hazard. Fatal if swallowed indicates acute toxicity via oral route.
Signal words used in GHS labels are Danger for more severe hazards and Warning for less severe hazards.
False
True
GHS uses two signal words: Danger for high severity and Warning for lower severity hazards to alert users.
A flammable liquid classified as Category 1 has a flash point at or below 23 C and a boiling point at or below 35 C.
False
True
Category 1 flammable liquids have flash points below 23 C and boiling points above 35 C. Liquids with lower boiling points fall into aerosol or gas categories.

False
OSHA allows employers to withhold specific chemical identities if they meet trade secret requirements, but hazard information cannot be withheld.
A hazardous chemical inventory list must include the common name and manufacturers name of each chemical.
False
True
An accurate inventory includes product identifier (common name) and supplier information so that SDSs can be matched properly.
Gases under pressure are exempt from classification under the Hazard Communication Standard.
False
True
Compressed gases are covered as physical hazards under HCS and must be classified and labeled accordingly.
In mixtures, components present at concentrations below 1% do not need hazard classification.
False
True
All hazardous components in mixtures must be considered; thresholds vary by hazard class, and some require classification at any concentration.
The Health Hazard pictogram covers carcinogenicity, respiratory sensitization, and reproductive toxicity.
False
True
The silhouette of a person with a starburst indicates serious health effects like carcinogenicity and reproductive toxicity under GHS.
Employers must provide annual refresher training on hazard communication regardless of workplace changes.
False
True
OSHA requires training at initial assignment and when new hazards are introduced. Annual refreshers are not mandated unless new information or changes occur.
Precautionary statements on labels must be specific to each hazard class and category.
False
True
Precautionary statements describe recommended measures to minimize risks and are standardized for each hazard class under GHS.
Section 8 of the Safety Data Sheet covers exposure controls and personal protective equipment.
False
True
SDS Section 8 provides details on permissible exposure limits, engineering controls, and recommended PPE to protect workers.
Section 3 of the Safety Data Sheet covers composition and information on hazardous ingredients.
True
False
Section 3 lists the chemical identity, common names, CAS numbers, and concentrations of hazardous ingredients.
Under OSHAs HCS, workplace labels must be in English only, even if a significant portion of employees speak another language.
True
False
OSHA requires labels in English but recommends employers provide supplemental translations where necessary for worker comprehension.

Cheat Sheet

  1. GHS Pictograms & Hazard Classes -

    Familiarize yourself with the nine GHS hazard pictograms (e.g., flame, skull and crossbones, exclamation mark) as outlined in OSHA 1910.1200. Remember "Red Diamond Means Danger" to recall that every pictogram sits inside a red diamond frame. Visualizing each symbol will boost your score on any GHS hazard communication quiz segment.

  2. Essential Label Elements -

    Every chemical label must include Product Identifier, Signal Word, Pictogram, Hazard Statement, and Precautionary Statement. Use the mnemonic "P-S-P-H-P" ("Please See Proper Hazard Protocols") to lock in that order. In your hazard communication quiz answers true or false, distinguishing "Danger" from "Warning" signal words can make all the difference.

  3. Safety Data Sheets (16 Sections) -

    Safety Data Sheets are standardized into 16 sections - Section 1 (Identification) through Section 16 (Other Information). Group them mentally: 1 - 3 for ID & hazards, 4 - 10 for emergency measures, 11 - 15 for toxicology and disposal, 16 for references. A quick practice: "Section 2 = hazard statements," so any true/false question on hazard classification clicks instantly.

  4. Written Hazard Communication Program -

    OSHA requires a written program that includes a current chemical inventory, container labeling, and SDS access for every hazardous product. Update your inventory immediately when new substances arrive - this simple habit will serve you well on the OSHA hazard communication quiz. Consistent record-keeping is a cornerstone of the hazard communication standard quiz and real-world compliance.

  5. Training & Quiz Prep Tips -

    Employees must receive hazard communication training at initial assignment and whenever new hazards are introduced, per OSHA guidelines. Use flashcards or quick true/false practice sets to tackle common hazard communication true or false questions effectively. Remember: active recall beats passive review - quiz yourself on pictogram names or SDS sections until you ace every question.
