When must safety goggles or glasses be worn?

Safety goggles or glasses must be worn any time there is potential danger to the eyes because they serve as a protective barrier against various hazards that can cause eye injuries. This includes exposure to flying particles, chemicals, intense light, or harmful substances that could lead to serious injuries or vision loss.

The emphasis on wearing protective eyewear whenever there's a risk underscores the importance of proactive safety measures in any environment, especially in horticultural practices where tools and chemicals are frequently used. While it could be argued that equipment manuals and training sessions dictate when safety gear is necessary, relying solely on those instances may leave workers vulnerable during other operations where dangers exist but are not specifically outlined. Therefore, a broad application of eye protection is the safest and most effective practice.
