What are the four main types of electrical injuries Electrocution, electric shock, burns, indirect (e.g., a fall from a ladder) Two of the main differences between the hydraulic rough terrain crane and the crawler lattice boom friction crane are In boom hoist and load line controls The greatest hazards posed by hand tools result in Misuse and improper maintenance In general, head protection should do which of the following? All of the above Anytime an adapter is used to accommodate a two-hole receptacle, the adapter wire must: Be attached to a known ground Prestressed concrete is often used in modern construction because Its unique strength allows predetermined engineering stresses to be placed in members to counteract stresses that occur when the unit is subjected to service loads The two best means of avoiding injury from electrical devices are: Insulation and grounding . If a powder-actuated tool misfires, the employee should: Wait at least 30 seconds, then try firing again OSHA defines an excavation as Any man-made cavity, depression, trench or cut in the earth's surface formed by earth removal Most OSHA electrical safety guidelines and regulations for construction are contained in Subpart K, 29 CFR 1926, which is based on: The National Electrical Code A green wire or green wire with yellow stripes is used to indicate an insulating conductor wire The three main scaffold types are aerial lifts, supported scaffolds and Suspended scaffolds An employer should provide whatever PPE is deemed necessary after performing a thorough Hazard assessment True or False: Employers must provide a training program that teaches employees who might be exposed to fall hazards how to recognize such hazards and how to minimize them, and must also prepare a written certification that identifies the employee trained and the date of the training.
