Questions: Which of the following is a potential workplace hazard? Noise induced hearing loss Heat exhaustion Non-ionizing radiation Back strain All of the above

The answer is the last one: All of the above.

Explanation for each option:

1. Noise induced hearing loss: This is a common workplace hazard, especially in environments with high levels of noise such as construction sites, factories, and airports. Prolonged exposure to loud noise can damage the inner ear and lead to permanent hearing loss.

2. Heat exhaustion: This is a potential hazard in workplaces with high temperatures, such as foundries, kitchens, or outdoor work sites during hot weather. Heat exhaustion can lead to serious health issues if not addressed promptly.

3. Non-ionizing radiation: This type of radiation, which includes ultraviolet (UV) light, microwaves, and radiofrequency radiation, can be a hazard in certain workplaces. For example, UV radiation can cause skin burns and increase the risk of skin cancer, while prolonged exposure to microwaves can cause thermal injuries.

4. Back strain: This is a common hazard in workplaces that involve heavy lifting, repetitive movements, or poor ergonomics. Back strain can lead to chronic pain and disability if not managed properly.

Since all the listed options are potential workplace hazards, the correct answer is "All of the above."

Summary: All the options provided (Noise induced hearing loss, Heat exhaustion, Non-ionizing radiation, Back strain) are potential workplace hazards. Therefore, the correct answer is "All of the above."
