The Occupational Safety and Health Administration (OSHA) promulgates safety and health standards. These standards typically apply to machinery (capital), which is required to be equipped with guards, shields, and the like. An alternative to these standards is to require the employer to furnish personal protective devices to employees (labor) such as earplugs, hard hats, and safety shoes. Analyze the possible employment effects of the second alternative approach if the OSHA believes that it offers greater protection from injury for the workers.
