OSHA 10 Test Answers With Complete Solution 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 PPE OSHA 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 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 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 Safety nets must be strong enough to support workers who fall, and must: - Have small enough mesh openings that employee doesn't fall through net itself Approximately 75 percent of struck-by fatalities involve: - Heavy equipment such as cranes or trucks It is preferable not to drive a vehicle in reverse if you have an obstructed rear view, but if you do, make sure: - Vehicle has an audible reverse alarm Workers are most at risk from falling objects when standing or working: - -- under scaffolds -- under cranes -- wherever overhead work is being performed To prevent injury from flying debris, use safety glasses, goggles, face shields, etc., where machines or tools may cause flying particles; and always inspect tools, such as saws and lathes, to ensure that: - The protective guards are in good condition and firmly attached Forklift operators should ground the forks of the forklift, turn the forklift off, set the parking brake, and _____________prior to dismounting the machine. - neutralize controls If a machine has an exposed pulley and conveyor but the portion of it that is exposed is well underneath the machine, the employer: - Must ensure all exposed and accessible sections of the machine are guarded One who is capable of identifying existing and predictable hazards in the surroundings, or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them is a/n ______________: - competent person Providing worker training on the safe use of the equipment being operated is the responsibility of the: - employer To protect against caught-in or -between hazards, a worker should not only avoid wearing loose clothing or jewelry, but also a worker should avoid: - Performing maintenance or adjustment on equipment/machinery that hasn't been locked-out There are a number of requirements that employers must do to protect their workers from caught-in or between hazards.
