What are the two primary methods for removing pipe insulation containing asbestos?

The two primary methods for removing pipe insulation containing asbestos are glove bag and full containment.

The glove bag method is a localized removal technique where a sealed plastic bag (the glove bag) is used to enclose the work area around an asbestos insulation piece. This method allows workers to safely remove the asbestos without exposing the surrounding environment to fibers. It is particularly effective for small-scale projects or for maintenance work where asbestos is found.

Full containment involves constructing a sealed enclosure around the area where asbestos work is to take place, which includes plastic sheeting and negative air pressure to prevent the escape of fibers into the environment. This method is used for larger or more hazardous removal projects and ensures the highest level of protection for both workers and occupants in nearby areas.

The other options, although related to asbestos handling, do not accurately describe the two primary methods for specifically removing pipe insulation. Dry and wet removal refers to general methods that may apply in different contexts of asbestos handling. Encapsulation involves sealing asbestos materials to prevent fiber release rather than their removal. Technique A and Technique B do not specify methods relevant to asbestos removal and are vague. Hence, glove bag and full containment are recognized as the most relevant methods for the situation described.
