Which of the following is a common hazard associated with chemical processes?

The selection of toxic releases, fire, or explosion as a common hazard associated with chemical processes is grounded in fundamental principles of process safety management (PSM). In many chemical processes, the handling of hazardous materials can lead to a variety of risks. Toxic releases can occur due to leaks, spills, or equipment failures, exposing workers and the environment to harmful substances. Additionally, chemical reactions can generate heat and gases, potentially resulting in fires or explosions if not properly controlled.

Chemical plants often operate under conditions where the presence of flammable materials and high-energy reactions increases the likelihood of such incidents. Thus, recognizing and mitigating the risks related to toxic releases, fires, and explosions is crucial to the safety of both the facility and its surrounding community.

The other options mentioned do address specific aspects of process operations, but they do not encompass the broader range of hazards that are significant in chemical processes. High temperatures can certainly be hazardous in certain contexts, and low-pressure environments can be relevant in specific situations, but they are not as universally recognized across various chemical processes as the combined risks of toxic releases, fires, and explosions.
