Hydrogen Sulfide is colorless, has an odor of rotten eggs, and is highly toxic. Although the odor is very pungent at first, it quickly deadens the sense of smell, so victims may be unaware of its presence until it's too late. Hydrogen Sulfide is flammable, naturally occurring in crude petroleum, natural gas, volcanic gas, and hot springs. It is sometimes called “sewer gas”. Biogas generators may release up to 1% hydrogen sulfide in gas streams. Any process that breaks down organic material without oxygen has the potential to create high levels of hydrogen sulfide. If heated under pressure it will explode. It is produced in the human body by bacteria in the mouth and gastrointestinal tract. Hydrogen Sulfide is very toxic to aquatic life and leaves long-lasting damage.
Hydrogen Sulfide Exposure and Health Risks
Hydrogen Sulfide is toxic and flammable. It is an irritant, causing inflammation and irritation to eyes and respiratory system. Eye pain, conjunctivitis, photophobia, corneal vesiculation and lacrimation (discharge of tears) are effects of Hydrogen Sulfide on the eyes. Dermal burns can result from direct contact. Inhalation can cause dizziness, headaches, insomnia, and fatigue. Gastrointestinal disturbances may occur as well. Hydrogen sulfide causes serious damage to organs and central nervous system, and it can be fatal if inhaled.
The table below summarizes the most-recent exposure limits.
Hydrogen Sulfide concentration in the air can be measured in units of parts per million (ppm). Many of our products have digital communication capabilities for easy monitoring and control. We carry portable and fixed hydrogen sulfide monitors and kits. All of our hydrogen sulfide products can be viewed HERE.
The C-16 allows for multiple gas sensors go be purchased and used. With a fast response time, and features such as data logging, alarms, and min,max,avg recording, this is a great all around gas sensor for most every use.
In the C-16 page choose the sensor that is right for you. H2S sensors are available in a 0-50 or 0-500 ppm range. Also choose other sensors that may be right for you.
The sensors used in the C-16 are also directly interchangeable with either the F-12, or D-12 toxic gas transmitters. This makes the C-16 the perfect handheld device to use along with wall mounted toxic gas transmitters.
The D-12 allows for multiple gas sensors go be purchased and used. The D-12 is designed for operation in hazardous areas. The cast aluminum housing for the D12 transmitter is rated for Class 1, Division 1, Group B, C, D locations and is UL, FM, and CSA certified.
In the D-12 page choose the sensor that is right for you. Hydrogen Sulfide sensors are available in a 0-50 or 0-500 ppm range. Also choose other sensors that may be right for you.
