What is a critical aspect of lighting design for workplace safety?

Adequate illumination for visibility is a critical aspect of lighting design for workplace safety because it directly impacts a worker's ability to see clearly and perform tasks effectively. Proper lighting helps prevent accidents and injuries by ensuring that all areas of a workplace are sufficiently lit, allowing workers to navigate their environment safely and comfortably. Good visibility minimizes the risk of tripping, falling, or misinterpreting hazards that might be present in the workplace.

While decorative lighting, consistent color temperatures, and energy-efficient bulbs can contribute to an overall pleasant and sustainable workplace environment, they do not directly address the fundamental need for proper illumination. Decorative lighting may enhance aesthetics but does little to ensure that all work areas are safely lit. Consistent color temperatures are important for maintaining visual comfort and understanding color but are secondary to the necessity of having enough light to see clearly. Energy-efficient bulbs contribute to sustainability and cost savings, but the primary concern must always be that the lighting is adequate to support safe work practices.
