Glove bags cannot be used on pipes or surfaces that exceed what temperature?

• A. 100°F
• B. 150°F
• C. 200°F
• D. 250°F

Answer: (B)

The key idea here is the temperature tolerance of glove bags, which are typically made from polyethylene. Polyethylene softens and can melt at relatively low heat, so exposing a glove bag to surfaces that are too hot risks rupture or loss of seal. Keeping the surface temperature at or below 150°F ensures the bag remains intact and able to contain any fibers or contaminants during wrap-and-seal work. If the surface were hotter, such as 200°F or 250°F, the bag could fail and defeat the containment, creating an exposure risk. A surface temperature of 100°F would be well within the bag’s capacity, but 150°F is the stated limit that safety guidelines use for determining when glove bags can be safely used.
