OSHA Focus Four Struck By Hazards
64 flashcards covering OSHA Focus Four Struck By Hazards for the OSHA OSHA 10/30 Construction section.
Struck-by hazards are one of the OSHA Focus Four categories, which address the most common causes of fatal injuries in construction and general industry. This topic covers risks like being hit by falling objects, flying debris, or moving equipment, as outlined in OSHA's 29 CFR 1926 standards for construction. These regulations emphasize hazard recognition, safe work practices, and the use of protective measures to prevent accidents on job sites.
On OSHA 10/30 Construction certification exams, questions often appear as multiple-choice scenarios asking about identifying struck-by risks or selecting proper controls, such as barricading or wearing hard hats. A common trap is overlooking indirect hazards, like tools rolling off surfaces, which can lead trainees to miss answers involving comprehensive site assessments.
Always inspect for unstable loads before starting work to catch potential struck-by dangers early.
