Why are gasoline or volatile organic solvents objectionable in a sewer?

• A. They present a serious explosion hazard
• B. They tend to cause corrosion
• C. They precipitate wastewater solids causing stoppages
• D. They increase resistance to flow

Answer: (A)

Gasoline and volatile organic solvents are objectionable in a sewer primarily because they present a serious explosion hazard. When these substances enter the sewer system, particularly in confined spaces, they can create a flammable atmosphere. The presence of these volatile compounds can lead to an accumulation of vapors, which, when exposed to an ignition source, can result in explosions. This risk not only endangers the safety of personnel working in and around the sewer system but also compromises the integrity of the sewer infrastructure. The other options, while they touch on issues that could arise with different types of waste, do not directly address the immediate and critical hazards posed by gasoline and organic solvents. Corrosion typically results from substances with high acidity or alkalinity rather than from hydrocarbons. Wastewater solids precipitation is more commonly associated with biological or chemical processes rather than the specific issue of organic solvents. Similarly, increasing resistance to flow generally pertains to solid materials or debris rather than volatile liquids.
