Final answer:
True, employers must provide training about the physical and health hazards of chemicals and how workers can protect themselves, following OSHA guidelines and safety standards.
Step-by-step explanation:
It is true that training must include both the physical and health hazards of the chemicals and how workers can protect themselves. According to the Occupational Safety and Health Administration (OSHA), employers have a responsibility to provide a safe workplace, which includes eliminating or reducing hazards where feasible, such as by switching to safer chemicals or using proper ventilation systems. Employers must inform and train workers about chemical hazards through methods like labels, alarms, and training programs. Ensuring the safety of workers involves compliance with established health and safety standards and the General Duty Clause of the OSH Act, which mandates that workplaces be kept free of serious recognized hazards even when no specific OSHA standard applies to the situation.
