Which type of workers does the OSH Act encompass?

The Occupational Safety and Health Act (OSH Act) is designed to ensure safe and healthy working conditions for a broad range of workers across various sectors. The correct answer highlights that it encompasses workers involved in charity and disaster relief. This is significant because the OSH Act applies to employees in all sectors, including those engaged in humanitarian efforts or emergency response activities, recognizing the importance of safety across diverse work environments.

Workers involved in charity and disaster relief often operate in potentially hazardous situations and need protections similar to those in traditional employment sectors. The OSH Act mandates that employers provide a workplace free of recognized hazards, which is vital even in settings that may not fit conventional employment classifications.

The incorrect options, while relevant to certain types of employment, do not capture the full scope of workers that the OSH Act intends to protect. The OSH Act is not limited to government sectors, high-risk industries, or solely the manufacturing sector, reflecting the law's comprehensive objective to promote workforce safety and health across all fields of work.
