The correct answer is that the four types of accidents included in OSHA's Focus Four program encompass falls, electricity, being caught in or between objects or equipment, and being struck by objects. Understanding these categories is essential as they represent the most common hazards leading to serious injuries and fatalities in the construction industry.

Falls are consistently among the leading causes of workplace accidents, highlighting the importance of fall protection measures. Electrical accidents involve risks associated with live wires, equipment failures, and improper work practices, which can lead to severe injuries or even fatalities. Being caught in or between objects or equipment pertains to scenarios where a person may be squeezed or pinned against an object, causing serious harm. Lastly, being struck by objects includes impacts from falling tools, materials, or equipment, which can be life-threatening.

Recognizing that these four categories collectively represent a significant portion of construction-related injuries underscores the importance of safety training and preventive measures in the industry. By focusing on these areas, OSHA aims to reduce the number of these common, yet potentially avoidable, accidents.
