Airborne Occupational Hazards in Sewer Systems

<p>Sewer systems fall into the category out of sight out of mind – they seldom excite interest. But when things go wrong with the air in the sewer system they go very wrong.

This book describes the atmospheric dangers commonly found in the sewer system. It provides easily-understood explanations of the science behind the hazards combined with real-life examples of when things went dramatically wrong.</p>
