Which of the following are considered to be physical hazards?

Physical hazards refer to environmental factors that can cause harm or injury to an individual. These hazards can take various forms, and in the case of the options provided, all listed factors are indeed classified as physical hazards.

Noise is a significant physical hazard, particularly in environments where loud sounds can lead to hearing loss or create challenges in communication. Prolonged exposure to high levels of noise can adversely affect health, making it essential to control sound levels in workplaces.

High pressure is another physical hazard often encountered in specific industrial settings. It can lead to physical injury if equipment fails or if individuals are operating under dangerous pressure conditions. Hazards associated with high pressure may include the risk of explosions or equipment malfunctions.

Temperature extremes represent yet another category of physical hazards—whether it’s excessive heat or extreme cold, both can cause serious health issues. Heat stress can lead to heat stroke or dehydration, while extreme cold can result in frostbite or hypothermia.

Given that noise, high pressure, and temperature extremes are all legitimate physical hazards that impact health and safety, the response identifying them collectively as a comprehensive answer captures the breadth of risks associated with physical hazards in various environments.
