Which type of fire-rated glazing does NOT qualify as safety glazing for hazardous locations?

Wired glass
Tempered glass
Glass block
None of the above

The correct answer is: Wired glass

Wired glass is specifically categorized as fire-rated glazing, but it does not meet the criteria for safety glazing as outlined in various building codes. Safety glazing is designed to reduce the risk of injury in hazardous locations, and wired glass can shatter, posing a danger to individuals. In contrast, tempered glass is manufactured to be much stronger than standard glass and is designed to break into small, less dangerous pieces, making it suitable for safety glazing applications. Glass block, while also fire-rated, offers the added benefit of not shattering upon impact, making it a safer option. Therefore, wired glass is the type of fire-rated glazing that fails to qualify as safety glazing in hazardous locations, as it does not provide the same level of safety as tempered glass or glass block.
