Which of the following fields does the American Society of Sanitary Engineers focus on?

The American Society of Sanitary Engineers (ASSE) primarily focuses on sanitation and safety in plumbing. This organization plays a critical role in establishing standards and practices that ensure the safety and sanitary conditions of plumbing systems. Their work includes the development of codes, guidelines, and training for professionals in the industry, promoting the importance of health and hygiene in water supply and waste management systems.

This emphasis on sanitation and safety in plumbing is essential, as it directly impacts public health by preventing contamination and ensuring that plumbing systems function effectively and safely.

The other options, while relevant to their respective fields, do not align with the specific mission and focus of the ASSE. For example, home construction relates to building practices rather than plumbing safety, electrical safety is concerned with electrical systems and hazards, and industrial engineering addresses broader aspects of engineering processes rather than specific plumbing safety and sanitation issues.
