Final answer:
The question involves Engineering, specifically the application of light-intensity standards in workplace environments. It refers to the requirement of a minimum of 30-footcandle light intensity to maintain safety and efficiency in certain classified areas.
Step-by-step explanation:
The mention of 30-foot candlelight intensity refers to the measure of illumination recommended for certain environments.
In engineering and health standards, especially in workplaces, light intensity is critical for safety and efficiency.
The term footcandle is a non-SI unit of illumination that quantifies how much light is cast on a surface.
One footcandle is defined as the illuminance on a one square foot surface from a uniform source of light with an intensity of one candela, located one foot away.
Building codes and occupational health regulations often specify a minimum light intensity for different environments to ensure sufficient visibility and to reduce the risk of accidents or eye strain.
Thus, the specification that a minimum of 30-footcandle light intensity shall be provided in all areas where activities are classified emphasizes the importance of adequate lighting in those areas for safety and functionality.
The complete question is: A minimum of 30 FOOTCANDLE light intensity shall be provided in all areas where all are classified. Justify!
