Employee hazards in collection system operations include which of the following?

• A. Noxious or toxic gasses or vapor.
• B. Oxygen deficiency.
• C. Physical injuries.
• D. All of the above

Answer: (D)

In sewer collection work, you have to be prepared for several kinds of hazards at once. Noxious or toxic gases or vapors can build up in manholes and pipelines, making exposure dangerous even if you don’t feel affected yet. Poorly ventilated, confined spaces can quickly become oxygen-deficient, increasing the risk of asphyxiation. And there are many physical hazards too—slips, trips, falls, heavy equipment, buried lines, and the possibility of being struck by vehicles or caught in machinery. Because all of these hazard types can be present in collection system operations, the best choice is the one that includes every risk category. In practice, this is why comprehensive safety programs emphasize gas monitoring, ventilation, confined-space procedures, PPE, lockout/tagout, and traffic controls to protect workers.
