Glazing in all fixed and operable panels of which type of doors are considered a hazardous location?

All types of doors—swinging, sliding, and bifold—can be considered hazardous locations when their glazing features are involved due to safety concerns regarding breakage and the potential for injury.

Fixed and operable panels in these doors are often made of glass, which can shatter upon impact, posing risks to individuals near the doors. Thus, the inclusion of glazing in any of these door types elevates the necessity for it to meet specific safety and performance standards.

In many building codes, the classification of hazardous locations applies uniformly across these door types. For instance, safety glazing materials, such as tempered or laminated glass, are often necessitated in these scenarios to minimize the risk of injury from cuts or lacerations resulting from broken glass. Given this consistent safety requirement across all three types of doors, the correct conclusion is that glazing in fixed and operable panels of swinging, sliding, and bifold doors is indeed recognized as a hazardous location.
