Sewer structures fall into the class "out of sight, out of brain" – they seldom excite curiosity. but if issues get it wrong with the air within the sewer approach, they pass very mistaken. effects should be dramatic and devastating: sewer employees killed immediately through toxic fuel after they elevate a sewer lid, or complete suburban blocks levelled by means of explosions. This booklet describes the atmospheric hazards ordinarily present in the sewer approach. It presents easily-understood motives of the technological know-how in the back of the dangers, mixed with real-life examples of whilst issues went dramatically wrong.

14 Airborne Occupational Hazards in Sewer Systems Rescuing coworkers who are trapped in confined spaces is challenging and dangerous. Estimates vary, but it seems clear that between one-quarter and one-half of all workers who die in confined spaces were trying to rescue other workers. It is human nature to offer assistance to those in peril; but sadly, the untrained rescuer tends to die along with the trapped worker whom they were trying to save. 3 Testing the Atmosphere Training the worker in the hazards is, in our opinion, the most important step to reducing the risk.
