Which organization requires a person to be trained in order to operate personal lifting equipment? OSHA The 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. 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. 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. 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. 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. 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 gas that needs to be contained. They are a crucial component in a wide range of mechanical and industrial processes. 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. 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 pin To 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. How often should you inspect any type of rigging device? before each use Rigging 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. ring gaskets may be affected by all of the following except? number of bolts Ring 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 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. CHAIN slings should be visually inspected? annually While 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. which way should the teeth face on a hack saw blade? away from the handle The 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. to prevent injury due to crushing between crane sand other objects what must be use? barricades To 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. which is true when comparing head pressure if a 1" pipe and a 10" pipe when both are 20' tall? the pressure is the same When 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 because head pressure, also known as hydrostatic pressure, is determined by the height of the fluid column, not its width or cross-sectional area. So as long as both pipes are filled to the same height with the same fluid, the pressure at the bottom of each will be the same. 15. when making a threaded connection the fitting stops on the 2nd thread the next step? stop something is wrong If a threaded fitting stops turning after only the second thread when making a connection, it is indeed a signal that something is wrong. It could indicate a problem such as cross-threading, incorrect sizing, or a defect in the threads. The appropriate action would be to stop immediately to prevent damage to the threads or components. The fitting should be removed and the issue diagnosed before attempting to proceed. This might involve inspecting and cleaning the threads, ensuring the correct parts are being used, or even replacing defective components. 16. when using a sealing ring on a heat exchanger what material is used to seal off in between the floating tube sheet and test ring? permatex In some cases, a sealing compound like Permatex may be used to seal off between the floating tube sheet and the test ring when performing a hydrostatic test on a heat exchanger. Permatex is a line of sealants that are often used in automotive and industrial settings, and they're known for their durability and resistance to heat and other challenging conditions. Please note that it's important to select the appropriate type of Permatex for the specific application and to follow all safety procedures and manufacturer's guidelines when applying it.
