A safety manual states: 'All workers must de-energize and lock out equipment before performing maintenance, unless the task requires the equipment to be energized, in which case appropriate PPE must be worn.' A technician needs to lubricate a moving conveyor belt. What does the manual require?
Answer: De-energize and lock out the belt before lubricating
Lubrication of a moving belt does not require it to be energized, so de-energize and lock out applies.
A passage reads: 'Conduit fill calculations ensure that the total cross-sectional area of all conductors does not exceed the permitted percentage of the conduit's interior area.' What is the primary purpose of conduit fill limits?
Answer: To prevent overheating and allow conductor installation
Conduit fill limits prevent overheating and make pulling conductors through conduit feasible.
An instruction sheet says: 'Tighten terminal screws to the manufacturer's specified torque value. Under-tightening causes arcing; over-tightening can damage the terminal.' A worker skips using a torque screwdriver. Which TWO risks does the passage identify?
Answer: Arcing from under-tightening and terminal damage from over-tightening
The passage explicitly names arcing (under-tightening) and terminal damage (over-tightening) as the two risks.
A code excerpt states: 'Receptacles installed in wet locations shall be in enclosures that are weatherproof whether or not the attachment plug cap is inserted.' What does 'whether or not the attachment plug cap is inserted' clarify?
Answer: The enclosure must be weatherproof at all times, regardless of plug status
The phrase means the weatherproof requirement applies continuously, not just in one state.
A work order reads: 'Replace the faulty 20 A breaker in panel B with a breaker of the same amperage and interrupt rating. Do not upsize.' A technician finds only a 30 A breaker available on the truck. What should the technician do based on the instructions?
Answer: Obtain the correct 20 A breaker before proceeding
The work order explicitly says 'Do not upsize,' so the technician must get the correct 20 A breaker.
A passage states: 'Aluminum conductors expand and contract more than copper conductors with temperature changes. Connections must use devices rated and listed for aluminum to prevent loosening over time.' Why must connections be specifically rated for aluminum?
Answer: Aluminum's greater thermal expansion can loosen connections not designed for it
The passage states that aluminum's expansion and contraction causes loosening, which rated connectors are designed to accommodate.
An OSHA directive reads: 'Employees shall not work alone in areas where immediate rescue may be required.' A worker is assigned to inspect a confined space alone. According to this directive, what is required?
Answer: At least one other person must be present or on standby
The directive prohibits working alone where immediate rescue may be needed, requiring another person present or on standby.
