New York Low Pressure Boiler COF Practice

Which inspections require the removal of hand and manholes?

1. External low-pressure inspections

2. Routine maintenance inspections

3. Internal high-pressure inspections

4. Visual safety assessments

The correct answer is: Internal high-pressure inspections

The requirement to remove hand and manholes during inspections is primarily associated with internal high-pressure inspections. This is because these inspections are designed to assess the internal condition of the boiler, including the presence of corrosion, scale build-up, or other structural issues that could compromise the integrity of the boiler when it is in operation. By removing manholes and handholes, inspectors gain access to critical areas that must be thoroughly examined to ensure safety and compliance with operational standards. In contrast, external low-pressure inspections typically involve checking the outside of the boiler and its components, without the need to access internal areas. Routine maintenance inspections may include various tasks, but they generally do not mandate the removal of access points unless specific internal examinations are required. Visual safety assessments focus on observable safety features and conditions, again without necessitating internal access. Thus, the correct answer reflects the specific need for internal access in high-pressure inspection scenarios.
