Final answer:
Employers are legally responsible for ensuring an emergency plan is in place to handle situations where injuries may occur, as per OSHA regulations.
Step-by-step explanation:
The responsibility to ensure that an emergency plan is in place to deal with incidents where injuries may occur falls primarily on the employer. According to OSHA (Occupational Safety and Health Administration) regulations, employers are required to provide their workers with a safe workplace, which includes the development of an emergency action plan. This plan should address the necessary steps to take in the event of different emergency situations, including immediate response to injuries. While an OH&S (Occupational Health and Safety) committee, which may include employees, can be involved in developing and reviewing the safety protocols, the ultimate legal responsibility lies with the employer. Employers must find and correct safety and health problems, inform workers about hazards, and attempt to eliminate or reduce these hazards through safer practices.
