JBL EMT Practice Exam

The correct answer is B. OSHA regulations do not guarantee a 100% risk-free environment, as it is impossible to completely eliminate all risks in a workplace. Option C is incorrect because OSHA regulations require employers to provide personal protective equipment to all employees who may be exposed to certain hazards, regardless of their employment status. Option D is incorrect because while OSHA does require employers to have a bloodborne pathogens exposure control plan, it does not explicitly state that all prospective employees must be screened for bloodborne pathogens prior to employment. Option A is incorrect because, as mentioned earlier, it is not possible for an employer to guarantee a completely risk-free environment.
