OSHA 10 Test Questions & Answers | 100% Correct Answers | Verified | Latest 2024 Version

The mission of the Occupational Safety and Health Administration (OSHA) is: - To send every worker home whole and healthy every day Electricity travels in closed circuits, and its normal route is through a conductor. Electric shock occurs when: - Your body becomes part of the circuit Workers need to take which of the following common-sense steps to protect themselves from falls through skylights and roof and floor openings? - -- Never sit on, lean against, or step on a skylight lens or any covering placed over a hole in a roof or floor -- Guard or securely cover all holes created or uncovered before leaving a work area -- Always use a PFAS when working over an unguarded or uncovered opening more than six feet above a lower level The two steps for avoiding hazards that are always taken before the need for PPE is considered are: - Workplace and engineering controls The three main scaffold types are aerial lifts, supported scaffolds and: - suspended scaffolds Because using cranes or derricks to hoist personnel poses a serious risk to the employees being lifted, any cranes and derricks that hoist personnel must: - -- Be placed on a firm foundation and be uniformly level within 1 percent of level grade -- Move the personnel platform slowly and cautiously and have rotation-resistant rope with a safety factor of 10 -- Have all brakes and locking devices set when the occupied personnel platform is in stationary position If the use of a power tool can result in flying sparks, metal shavings, wood chips, splashes, or other debris, workers should: - Protect themselves by wearing proper PPEOSHA defines an excavation as: - Any man-made cavity, depression, trench or cut in the earth's surface formed by earth removal A training program to teach proper lifting techniques should cover: - -- Knowledge of the basic anatomy of the spine, muscles, and joints of the trunk -- The use of safe lifting postures and timing Mechanical demolition refers to demolition using equipment like: - wrecking balls and jackhammers OSHA's electrical standards are based on: - the NEC 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 usageWhat 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 deenergized, 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 detectedAEGCP'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 includ
