1. 1. Which organization requires a person to be trained in order to operate
personal lifting equipment?: OSHAThe Occupational Safety and Health
Administration (OSHA) requires that persons operating personal lifting equipment,
or any kind of machinery, must be properly trained. This includes training in the
operation of the equipment, understanding the hazards associated with its use, and
the implementation of safety precautions to prevent accidents and injuries.
2. 2. Where would the usage of a RTJ Gasket be found?: high-pressure and
high-temperature systems Ring Type Joint (RTJ) gaskets are often used in high-
pressure and high-temperature systems, such as oil and gas industry pipelines,
valves, and pressure vessels. These gaskets are designed to withstand harsh
conditions and provide a robust seal. They are typically used in flanged connections
that have grooves designed to accommodate the RTJ gasket, providing a metal-to-
metal seal.
3. 3. All of the following are examples of internal manway hardware
except?: "slide fastener" Internal manway hardware typically includes components
such as cover plates, yokes, wing nuts, hinges, gaskets, and bolts. In this context,
all these are examples of internal manway hardware, but a "slide fastener" is not
typically part of the internal manway hardware. A slide fastener is a more general
term that could refer to various types of fasteners, such as zippers, which are not
typically found in manway hardware. Therefore, a slide fastener would not be
considered an example of internal manway hardware.
4. 4. What type of wrench measures how much a fastener is being
tightened?: "torque wrench" The type of wrench that measures how much a
fastener is being tightened is known as a "torque wrench". This tool allows the user
to set the amount of torque applied to the fastener, providing a precise level of
tightness. It's critical for applications where the tightness of screws and bolts is
crucial.
5. 5. the fitting that makes it easy to disassemble threaded piping is?:
"union" The fitting that makes it easy to disassemble threaded piping is commonly
known as a "union". A union fitting allows two parts of a pipe assembly to be taken
apart without needing to move other components, making it especially useful in tight
spaces or complex assemblies. This can greatly simplify tasks like maintenance
and repair.
6. 6. what is the purpose of a gasket?: to create a seal between two stationary
parts A gasket's primary purpose is to create a seal between two stationary parts.
It fills the space between two or more mating surfaces, usually to prevent leakage
from or into the joined objects while under compression. Gaskets can be made from
a variety of materials, depending on the specific application and the type of fluid or
, “ Boilermaker : The Ultimate NCCER Review Guide”
gas that needs to be contained. They are a crucial component in a wide range of
mechanical and industrial processes.
7. 7. What is the 1st consideration when making a gasket?: "material
compatibility" The first consideration when making a gasket is the "material
compatibility". This refers to selecting the appropriate gasket material that can
withstand the operating conditions where the gasket will be used. Material
compatibility includes considering:
1. The type of fluid or gas that the gasket needs to contain.
2. The operating temperature and pressure.
3. Any potential chemical interactions between the gasket material and the
substance it is sealing.
4. The type of connection (flange type, bolt pattern, etc.)
These factors are crucial as they will dictate the type of material you should use
for the gasket. It's important to ensure that the chosen material is compatible with
the operating conditions to prevent failures and ensure safety and longevity of the
gasket.
8. 8. In order to get the bundle to line up with the shell side gasket the best
tool to use to lift the bundle is a?: Drift pinTo line up a tube bundle with the shell-
side gasket during assembly or maintenance, a tool called a "drift pin" can often be
the best approach. While "bundle lifters" or "tube bundle extractors" are specialized
tools designed to lift, extract, or insert tube bundles in heat exchangers, boilers, or
similar equipment, a "drift pin" is used for more precise adjustments in the alignment
of components. The drift pin helps in accurately positioning the tube bundle, making
it easier to align it with the shell-side gasket. As always, the exact tool and method
can vary depending on the specific design of the equipment. Always follow
manufacturer's guidelines and safety protocols.
9. 9. How often should you inspect any type of rigging device?: before each
useRigging equipment should be inspected prior to each use and also periodically
inspected in a comprehensive manner, ideally by a trained, competent person. The
exact frequency of these more thorough inspections can vary based on the
equipment used, its frequency of use, and its exposure to wear and tear, but many
guidelines suggest a complete inspection at least annually. Always follow your
company's safety guidelines and any applicable regulations.
10. 10. ring gaskets may be affected by all of the following except?: number
of boltsRing gaskets can be affected by several factors, but the number of bolts on
a flange doesn't directly affect the gasket. Torque on the bolts and system
, “ Boilermaker : The Ultimate NCCER Review Guide”
temperature are factors that can affect a gasket's performance. Torque must be
correctly applied to achieve a proper seal, and the gasket material must be suitable
for the system's operating temperature. However, the number of bolts is typically a
function of the flange design and doesn't directly influence the gasket's
effectiveness.
11. 11. CHAIN slings should be visually inspected?: annuallyWhile chain
slings should indeed be inspected prior to each use, a more comprehensive
inspection is typically required on a periodic basis, often annually. This is because
some potential issues may not be immediately visible during a cursory pre-use
inspection.
The periodic, more thorough inspection is often carried out by a trained and
competent person and involves a detailed examination of each individual link and
component of the chain sling. It can help identify any wear, deformation, or damage
that might have occurred over time and is not immediately obvious.
The annual inspection is a standard suggested by many safety organizations and
regulations, but the exact frequency can depend on the frequency and nature of
sling use, previous inspection results, and environmental conditions. Always follow
your local regulations, manufacturer's guidelines, and company safety protocols.
12. 12. which way should the teeth face on a hack saw blade?: away from the
handleThe teeth on a hacksaw blade should face forward, away from the handle.
This is known as the "push" orientation, as it allows the tool to cut the material when
you push the saw away from you. This setup leverages the natural strength and
motion of your arm and body, and is the most common and effective way to use a
hacksaw.
13. 13. to prevent injury due to crushing between crane sand other objects
what must be use?: barricadesTo prevent injury due to crushing between cranes
and other objects, it's crucial to use safety measures such as barricades. Barricades
serve to establish a clear safety zone around the operating area of the crane. This
helps keep personnel and other equipment at a safe distance from the crane and
its load. In addition to barricades, effective communication methods such as radios
or hand signals should be employed, and in certain situations, the use of spotters
or signal persons may be necessary to guide crane operations.
14. 14. which is true when comparing head pressure if a 1" pipe and a 10"
pipe when both are 20' tall?: the pressure is the sameWhen comparing head
pressure in two different pipes of the same height (20 feet in this case), but different
diameters (1 inch and 10 inches), the head pressure will be the same. This is
