Question

multiple choice: choose the correct answer.1.  when working around a power line carrying more than 50kv, the safe minimum distance of 10 must be increased for each additional 1kv by ______a.  0.4b.  0.5c.  0.8d.  12.  when using power tools to work on advanced wall systems, electrical cords should be checked ______ to see if they are in good condition.a.  by a supervisorb.  at least once a weekc.  at the end of every shiftd.  before they are used in a wet area3.  workers should always use ______ ladders when working around power lines.a.  conductiveb.  steelc.  non-conductived.  aluminum4.  curtain walls are constructed primarily from ______a.  oriented strand boardb.  plywoodc.  glassd.  gypsum board5.  for structural insulated panels (sips), the width of the sill plate is ______ the space between the panels.a.  half the size ofb.  equal to the size ofc.  twice the size ofd.  three-quarters the size of6.  insulated wall systems consisting of foam material sandwiched between sheets of osb or plywood are referred to as ______a.  impsb.  sipsmodule 27404 practice examnote: this exam is not eligible for a credential.provided that copies are for local use only and that each

Accepted Answer

# Brief Explanations:
1. For power lines over 50kV, OSHA standards specify the safe distance increases by 0.4 feet per additional 1kV.
2. To prevent electrical hazards with power tools in wet areas, cords must be inspected before use in such environments.
3. Non-conductive ladders avoid electrical shock risks near power lines, as they do not conduct electricity.
4. Curtain walls are exterior cladding systems primarily made of glass (along with metal framing) for modern buildings.
5. For structural insulated panels (SIPs), the sill plate width matches the space between panels to support the panels properly.
6. Insulated wall systems with foam between OSB/plywood are Insulated Metal Panels (IMPs), though the acronym here refers to this type of sandwich panel system.

# Answer:
1. a. 0.4'
2. d. before they are used in a wet area
3. c. non-conductive
4. c. glass
5. b. equal to the size of
6. a. IMPs
