A height safety company is a firm that supplies materials, equipment, technology, and/or processes to prevent construction workers from falling on projects of great height. Equipment often comprises barriers or ropes to keep workers secure.

The purpose is to prevent falls by construction workers on projects of great height. The supply can be physical equipment or a process or technology, so the definition is broader than manufacture of barriers or ropes alone.

A fall protection system manufacturer makes protective equipment. Height safety also includes the other means of keeping workers secure described above, while occupational safety and health concerns building safety and health conditions more broadly.
