Physical education lessons are always associated with an increased risk of injury. This imposes high requirements for the implementation of safety precautions on physical education teachers. The teacher, as well as each student, must strictly adhere to the established rules. The management of the educational institution is obliged to ensure that the sports hall, the open sports ground, as well as sports equipment and any optional equipment used in the classroom. In the event that a physical education teacher finds that any objects related to classes do not comply with established standards, he must immediately notify the school management and stop using them in lessons until the danger is eliminated. Assumes that students will be familiar with it even before they start classes. The safety rules are aimed at minimizing injuries during lessons and are mandatory for all participants in the learning process.
Here we present only ground rules physical education safety equipment. Each educational institution may modify or supplement the list of prohibited or permitted activities in accordance with local conditions. We also recommend that you read the article " Safety in labor lessons in the workshop". And for elementary school teachers, the material posted on our website may be of interest, " Safety rules at labor lessons for younger students"
