the wastewater treatment industry is an extremely unsafe occupational
field. This less than stellar historical safety performance has continued
to deteriorate, even in the age of the Occupational Safety and Health Act
(OSH Act). The question is “Why is the wastewater treatment industry
on-the-job injury rate so high?”
Several factors contribute to this high injury rate. In the first place,

Physical injuries
Toxic gases and vapors
Infections

wastewater industry also has:
Complex treatment systems
Shift work
New employees
