Which of the following is an example of a physical hazard?

Excessive noise is classified as a physical hazard because it relates directly to environmental conditions that can cause harm to the human body. In occupational settings, prolonged exposure to high decibel levels can lead to hearing loss or other auditory issues. The effects of excessive noise are measurable and can often result in immediate safety concerns, such as distractions that may lead to accidents.

Other options, while important in health and safety discussions, fall under different categories. Chemical spills are categorized as chemical hazards since they involve substances that can be toxic or harmful. Stress from work demands is considered a psychosocial hazard, affecting mental well-being and job performance rather than presenting a direct physical risk. Inadequate lighting can lead to accidents and errors but is typically classified as an environmental or ergonomic hazard rather than a physical hazard in the same context as noise.
