OSHA 10 Test Answers 100 Percent CORRECT

What are the four main types of electrical injuries? ✔✔Electrocution, electric shock, burns, indirect (e.g., a fall from a ladder) A shock's severity depends on: ✔✔-- Length of exposure to electricity -- The amount of current and its frequency -- The current's path Electrical burns are the most serious of the three major types of burns, and most often occur: ✔✔On the hands, from direct contact with current Hot wires, ungrounded wires that can cause a shock if you touch them, are usually: ✔✔black or red More than 50 percent of electrocutions are caused by a worker coming in direct contact with: ✔✔energized power lines The OSHA standard requires flexible cords to be rated for: ✔✔Hard or extra hard usage What is the most frequent violation of OSHA electrical standards? ✔✔improper grounding of circuitry and equipment The three elements of a basic program for electrical safety are: ✔✔recognize, evaluate and control All portable electric tools that are damaged shall be: ✔✔Removed and tagged "Do Not Use" If you have a three-prong plug and a two-hole receptacle, it is acceptable to: ✔✔Use an adapter with an adapter wire connected to known ground All hazards involved in the use of power tools can be prevented by following five basic safety rules: Keep all tools in good condition with regular maintenance; examine each tool for damage before use; operate according to the manufacturer's instructions; provide and use the proper protective equipment; and: ✔✔use the right tool for the job Live parts of electric equipment operating at 50 volts or more must be: ✔✔guarded against electrical contact While any employee is exposed to contact with parts of electric equipment or circuits that have been de-energized, the circuits energizing the parts shall be: ✔✔Locked out or tagged out or both Low voltage does not mean low hazard. ✔✔true The two best means of avoiding electrical shock or injury when working with power tools are: ✔✔Insulation and grounding The majority of today's power line accidents occur because: ✔✔Of failure to maintain proper work distances A ground-fault circuit interrupter (GFCI) protects workers from shock by: ✔✔Matching the amount of current going into an electrical device against the amount returning from the device and shutting down power if a ground fault is detected AEGCP's are implemented on construction sites to oversee: ✔✔-- All cord sets -- Cord sets and equipment connected by plug and cord -- Receptacles that are not part of a building or structure The OSHA standard mandates that any time a worker is at a height of six feet or more, the worker is at risk and needs to be protected. Most fatalities, however, happen when workers fall from: ✔✔Roofs Employers must ensure that all walking and working surfaces have the structural integrity to: ✔✔Support workers safely Controlled access zones serve a dual purpose - they allow specially trained individuals (such as masons) to operate without traditional fall protection within a certain area, and: ✔✔They keep unauthorized individuals out A system used to arrest a worker in a fall from a working level that consists of an anchorage, connectors, a body belt or body harness, and may include a lanyard, deceleration device, lifeline, or suitable combinations of these is called a: ✔✔Personal Fall Arrest System (PFAS) When no other alternative fall protection has been implemented, the employer shall implement a safety monitoring system. Employers must: ✔✔Ensure that the safety monitor is a competent person knowledgeable about fall protection At holes, guardrail systems must be set up: ✔✔On all unprotected sides and edges The top edge of a guardrail must be from 39 to 45 inches above the walking/working level, and there must also be a means of protection from: ✔✔Falling objects between top rail and walking surface
