HAZMAT Technician Practice Exam

What is the greatest hazard associated with aromatic hydrocarbons?

1. Flammability

2. Toxicity

3. Corrosiveness

4. Reactivity

The correct answer is: Toxicity

Aromatic hydrocarbons, which include compounds like benzene, toluene, and xylene, are known primarily for their toxicity, making this the greatest hazard associated with them. These compounds can have serious health effects upon exposure, such as causing neurological damage, respiratory issues, and increasing the risk of cancer with prolonged or significant exposure. Toxicity represents a critical concern not only for individuals handling these substances but also for the environment, as they can contaminate water sources and soil. While flammability is also a noteworthy hazard due to the fact that many aromatic hydrocarbons are volatile and can easily ignite, the primary concern in terms of immediate health risks is toxicity. Corrosiveness is less relevant to aromatic hydrocarbons compared to their toxic nature, as these compounds generally do not have corrosive properties. Reactivity tends to be a concern with certain chemicals, but aromatic hydrocarbons are more stable compared to more reactive compounds found in other classes of hazardous materials. Therefore, toxicity stands out as the most pressing hazard associated with aromatic hydrocarbons.
