Final answer:
To mark parts in hot and cold sections during repair, use markers that can withstand high temperatures for the hot section and regular permanent markers or paint markers for the cold section.
Step-by-step explanation:
In repair work, it is important to mark the parts in hot and cold sections to ensure proper handling and prevent accidents. When marking parts in the hot section, it is crucial to use markers that can withstand high temperatures. This includes markers specifically designed for use in high-temperature environments, such as heat-resistant paint markers or metal etching markers. These markers are able to withstand the heat without smudging or fading.
For marking parts in the cold section, regular permanent markers or paint markers can be used. These markers are typically able to withstand lower temperatures and provide a permanent mark that will not easily wear off.
By using the appropriate markers for each section, repair personnel can ensure that parts are correctly identified and handled, minimizing the risk of errors or accidents.
