Which of the following is considered a type of interim control?

Interim controls refer to methods used to reduce or manage lead exposure in environments where lead hazards are present, particularly in homes or buildings with lead-based paint. Special cleaning, as a type of interim control, focuses on reducing lead dust and debris that can pose health risks, especially for children and pregnant women. This approach typically involves thorough cleaning techniques, including wet wiping and HEPA vacuuming, to eliminate lead-contaminated dust from surfaces.

Using special cleaning as an interim control is effective in providing a temporary solution to lead hazards, allowing occupants to remain in the space without immediate risk of lead exposure while longer-term solutions, such as complete abatement or removal of lead hazards, are planned or implemented.

In contrast, complete removal of lead and soil replacement are considered permanent abatement methods, which involve the significant alteration or removal of lead sources. Installation of new windows may also involve removing lead-paint surfaces and thus can be classified more as a renovation that may lead to permanent disconnection from lead hazards rather than a temporary measure.

By focusing on the immediate need to reduce lead exposure through regular cleaning practices, special cleaning is a sensible and practical interim control strategy recognized in lead hazard management.
