1Under the Hazard Communication Standard (29 CFR 1910.1200), what information must be included in Section 2 of a Safety Data Sheet (SDS)?

A.First-aid measures and firefighting procedures

B.Hazard classification, signal word, hazard statements, and precautionary statements

C.Manufacturer contact information and product identifier

D.Physical and chemical properties of the substance

Explanation: Section 2 of the SDS contains Hazard Identification, including hazard classification, signal word (Danger or Warning), hazard statements, precautionary statements, and pictograms. This section provides the critical hazard warning information required under the Globally Harmonized System (GHS) of Classification and Labeling of Chemicals.

2Which of the following is NOT one of the three principles of pollution prevention (P2) hierarchy?

A.Source reduction

B.Recycling and reuse

C.Treatment and disposal

D.Energy recovery

Explanation: The pollution prevention hierarchy prioritizes: 1) Source reduction (most preferred), 2) Recycling and reuse, 3) Treatment, and 4) Disposal (least preferred). Energy recovery is not part of the core P2 hierarchy, though it may be considered as an alternative to disposal. The goal of P2 is to eliminate or reduce pollution at the source before it is created.

3A facility wants to substitute a hazardous solvent with a less hazardous alternative. According to pollution prevention principles, what is the first step in evaluating alternatives?

A.Conduct a trial production run

B.Assess whether the alternative will perform the required function

C.Calculate the cost savings

D.Dispose of existing inventory of the hazardous solvent

Explanation: When evaluating alternatives for pollution prevention, the first step is to assess whether the alternative can perform the required function. Technical feasibility must be established before considering economic, environmental, or health factors. This ensures the substitution will not compromise product quality or process effectiveness.

4Which GHS pictogram indicates a material that may cause serious health effects such as cancer, respiratory sensitization, or reproductive toxicity?

A.The flame symbol

B.The exploding bomb symbol

C.The health hazard symbol (silhouette of a person with a starburst)

D.The corrosion symbol

Explanation: The health hazard pictogram (silhouette of a person with a starburst over the chest) indicates carcinogenicity, mutagenicity, reproductive toxicity, respiratory sensitization, target organ toxicity, or aspiration toxicity. The flame indicates flammability, the exploding bomb indicates explosives or self-reactives, and the corrosion symbol indicates skin corrosion or serious eye damage.

5Under RCRA, how long can a generator accumulate hazardous waste on-site without a permit if the waste is managed in a 90-day accumulation area?

A.30 days

B.55 days

C.90 days

D.180 days

Explanation: Large Quantity Generators (LQGs) may accumulate hazardous waste on-site for up to 90 days without a RCRA permit, provided the waste is managed in a designated 90-day accumulation area that meets specific requirements for containment, labeling, and inspections. Small Quantity Generators (SQGs) may accumulate for up to 180 days (or 270 days if shipping distance exceeds 200 miles).

6What is the primary purpose of a chemical inventory in hazardous materials management?

A.To track purchasing costs only

B.To identify all chemicals present for regulatory compliance, emergency response, and risk assessment

C.To satisfy insurance requirements only

D.To determine employee bonuses for safety performance

Explanation: A comprehensive chemical inventory identifies all hazardous materials present in a facility, enabling regulatory compliance (EPA, OSHA, fire codes), emergency response planning, risk assessment, and proper storage arrangements. It should include chemical names, quantities, locations, SDS locations, and hazard classifications.

7In the recycling hierarchy, which option is considered the highest value recovery?

A.Energy recovery through incineration

B.Use as a fuel substitute

C.Direct reuse without processing

D.Reclamation to recover valuable components

Explanation: The recycling hierarchy ranks recovery options by value: 1) Direct reuse (use of waste as a product in its original form without processing), 2) Reclamation (processing to recover valuable materials), 3) Use as a fuel substitute, and 4) Energy recovery (incineration). Direct reuse requires minimal processing and preserves the maximum material value.

8According to the Toxic Substances Control Act (TSCA), what must manufacturers submit to EPA before producing a new chemical substance?

A.A pollution prevention plan

B.A premanufacture notice (PMN)

C.A material safety data sheet

D.A RCRA permit application

Explanation: TSCA Section 5 requires manufacturers to submit a Premanufacture Notice (PMN) to EPA at least 90 days before producing or importing a new chemical substance. The PMN must include chemical identity, use, anticipated production volume, byproducts, exposure data, and available test data on health and environmental effects.

9What is the flash point range for a liquid to be classified as a Class II combustible liquid under OSHA definitions?

A.Below 73°F (22.8°C)

B.At or above 73°F (22.8°C) and below 100°F (37.8°C)

C.At or above 100°F (37.8°C) and below 140°F (60°C)

D.At or above 140°F (60°C) and below 200°F (93.3°C)

Explanation: Under OSHA 29 CFR 1910.106, Class II combustible liquids have a flash point at or above 100°F (37.8°C) and below 140°F (60°C). Class IA flammable liquids have flash points below 73°F and boiling points below 100°F. Class IB flammable liquids have flash points below 73°F and boiling points at or above 100°F.

10Which characteristic identifies a hazardous waste as "reactive" under RCRA?

A.It has a pH less than 2 or greater than 12.5

B.It is capable of detonation or explosive decomposition

C.It contains mercury above regulatory thresholds

D.It is liquid and contains less than 24% alcohol by volume

Explanation: A reactive hazardous waste (D003) is normally unstable, reacts violently with water, forms potentially explosive mixtures with water, generates toxic gases when mixed with water, is capable of detonation or explosive decomposition, or is a forbidden explosive. A pH less than 2 or greater than 12.5 indicates corrosivity (D002), not reactivity.
