Which of the following methods is restricted during paint abatement?

During paint abatement, using a heat gun above 1100°F is restricted due to safety and health concerns. When lead-based paint is heated to high temperatures, such as above 1100°F, it can produce lead fumes and toxic particles that pose serious health risks to workers and occupants nearby. This is particularly critical in any environment where lead hazard control is necessary, as the goal is to minimize exposure to lead dust and fumes.

In paint abatement practices, various methods are employed to safely remove lead-containing materials, but those that are likely to generate harmful lead-laden dust or fumes must be carefully regulated or prohibited altogether. By restricting the use of heat guns at high temperatures, the regulations aim to protect both the workers conducting the abatement and those who live in the affected areas.

Other methods, such as hand sanding or water washing, can be utilized with appropriate safety measures in place to mitigate lead exposure, and using air spray can also involve different levels of risk if not handled correctly, but it is the high-temperature heat gun method that presents the most immediate and intense hazard, which is why it is specifically restricted.
