Welcome to the “Near Misses” video course intended to help learners understand why close calls occur and work to prevent them from happening—all in an effort to avoid injury and illness on the job. This course, which comprises three video lessons, defines near misses and explains why they often occur in the workplace. Viewers will learn what constitutes a near miss and the factors that contribute to risky behavior through a variety of scenarios. Ultimately, learners should understand what to do if they experience a near miss and recognize how to avoid making the same mistakes in the future. (Keywords: self-awareness, bias, reporting)
