A hazard is defined as a chance; a chance of being injured or harmed by a possible source of danger. Jobsites are filled with many different hazards- whether it's the task you are performing, task others are performing around you, equipment, chemicals, heat sources, or weather conditions. Hazards should be recognized and eliminated through engineering controls, administrative controls, and as a last resort, personal protective equipment.
According to the FBI, in 2014 and 2015 alone, a total of 40 active shooter incidents occurred in the United States. While the average number of incidents per year is increasing, the statistical risk of being affected by an active shooter is still relatively low for any given employer.
Workers who are exposed to extreme heat or work in hot environments may be at risk of heat stress. Exposure to extreme heat can result in occupational illnesses and injuries such as heat stroke, heat exhaustion, heat cramps, or heat rashes. Heat can also increase the risk of injuries in workers as it may result in sweaty palms, fogged-up safety glasses, and dizziness. Burns may also occur as a result of accidental contact with hot surfaces, sun exposure, or steam.
In July 2016, the National Safety Council launched an initiative on occupational fatigue. "Aside from just an increase in workplace risk, there's also long-term economic consequences," said Emily Whitcomb, senior program manager of the initiative. "NSC is tackling fatigue because as we're working toward eliminating preventable deaths, fatigue is one of the larger issues."
