Why is it necessary to wear safety glasses when threading pipe?

Wearing safety glasses while threading pipe is crucial primarily for the protection of the eyes from metal shards. When pipes are threaded, particularly with cutting tools, small metal particles can be produced as a result of the cutting or threading process. These sharp, tiny pieces can easily become airborne and pose a significant risk to the eyes. Safety glasses act as a barrier, preventing these harmful particles from penetrating the eyes and causing injuries that could lead to serious vision problems or permanent damage.

The importance of wearing eye protection in this context highlights the inherent risks involved in working with metal and tools, where sharp objects and debris can be present. By prioritizing eye safety, individuals reduce the chance of accidents and promote a safer working environment.
