Missouri Work Comp Injury – Sewer Workers Exposed to Toxic Gases

Sewer workers are exposed to dangerous working conditions from toxic and flammable gases.

Sewer workers may spend large amounts of time under a tunnel, in a sewer, or in other types of confined places. These types of jobs are exposed to a higher risk of work-related illness and accidents, such as exposure to the risk of fire hazards due to the presence of flammable gases. Many accidents occur when workers inhale toxic gases.

Exposure to Toxic Gases

Those who work in sewers are more likely than other underground workers to suffer an illness or injury due to exposure to toxic gases. This is because sewers or underground channels have drains that release toxic gases as waste matters decompose. Toxic gases released from sewers contain hydrogen sulfide. Hydrogen sulfide is released when bacteria starts decomposing organic materials. When a worker inhales hydrogen sulfide, he or she may experience several symptoms, including:

  • loss of consciousness
  • suffocation
  • breathing problems
  • loss of the sense of smell
  • paralysis

Exposure to Hydrogen Sulfide

Initially, a worker may smell an odor similar to a rotten egg when exposed to hydrogen sulfide. In addition to hydrogen sulfide, a sewer may release other harmful gases, such as carbon monoxide, nitrogen oxides, and ozone. Some gases, like carbon monoxide, do not have any odor or color. As a result, the worker may not be aware of exposure to harmful, toxic gases until serious symptoms develop. Long-term exposure to toxic gases, such as carbon monoxide, chlorine, hydrogen sulfide, hydrogen cyanide, and arsine can be lethal.

Preventing Work-Related Accidents

Every year, over 5,000 workers get injured and another 50 deadly accidents occur in confined places. The Occupational Safety and Health Administration (OSHA) released regulations on Permit-Required Confined Spaces in January 1993 in an attempt to prevent accidents due to exposure to harmful toxic gases in a confined place. OSHA guidelines require that workers use a self-contained breathing apparatus (SCBA) while working in a sewer or any confined place that has less than 19.5 percent oxygen concentration in the air.

An employer is responsible for making sure that working conditions inside a sewer do not pose a life-threatening risk to their workers. Workers should be equipped with the appropriate tools to avoid accidents and illnesses due to exposure to toxic gases in a sewer or any confined place.
