The recommended type of glass for safety in hazardous locations is both tempered and laminated glass. Each type offers unique protective features that contribute to reducing the risk of human impact injuries.

Tempered glass is manufactured through a process of extreme heating and rapid cooling, which increases its strength compared to regular glass. When broken, it shatters into small, blunt pieces that are less likely to cause serious injuries, thus minimizing the potential for cuts or lacerations.

Laminated glass consists of layers of glass with a plastic interlayer, which keeps the glass bonded even when shattered. This prevents the glass from breaking into sharp, dangerous shards and adds an additional layer of safety by maintaining the integrity of the glazing, thus reducing the likelihood of injury from falling or flying glass fragments.

Using both tempered and laminated glass in hazardous environments ensures maximum protection, making environments safer for occupants. In contrast, wire glass, while providing some reinforcement, can still break into sharp shards, and standard glass lacks the safety features found in tempered and laminated versions. Therefore, the option encompassing both tempered and laminated glass addresses the requirements for safety in hazardous locations effectively.
