What type of PPE is mandatory on most construction sites?

High-visibility clothing is mandatory on most construction sites because it enhances the visibility of workers in environments where they may be exposed to moving vehicles and equipment. This type of personal protective equipment is essential for minimizing the risk of accidents, particularly in busy construction zones where safety is a primary concern.

The bright colors and reflective materials help ensure that workers can be easily seen by their colleagues and machine operators, reducing the likelihood of collisions or injuries. High-visibility clothing is particularly crucial in low-light conditions or outdoor settings during poor weather when visibility may be compromised.

While the other types of PPE mentioned, such as ear protection, respiratory masks, and fall protection harnesses, are also important for specific hazards on construction sites, high-visibility clothing is universally required across various types of construction work due to its fundamental role in worker safety. Each of these other PPE items addresses specific risks, but they do not serve the same broad purpose of enhancing visibility in the same way high-visibility clothing does.
