Mandatory safety equipment in ice hockey includes a helmet, face shield or visor, shoulder pads, elbow pads, and shin guards. These protective items are designed to minimize the risk of injury from impacts, falls, and contact with the puck or sticks. Players are also required to wear a jersey that covers their upper body properly, along with supportive skates to enhance mobility. Adhering to these regulations not only promotes safety but upholds the competitive integrity of the sport, ensuring that players can perform at their best while minimizing injury risks.
