Description

Integrity Calibration Gas replacement for ISC P/N 1810-0859: 25 ppm H2S/ balance air

Cylinder Size: 58 liters
Shelf life: 3 years

Why buy an Integrity Calibration Gas Standard?  It’s really simple- you should Buy Direct from the manufacturer to get the best price.

Integrity Gases, Inc. is the premier manufacturer of calibration gas standards in portable cylinders.  OEM Gas Detector Manufacturers are resellers.  We at Integrity Gases actually make calibration gases.  That’s why our prices are better than OEM’s and distributors.

1. Integrity Calibration Gas Standards meet or exceed the most demanding industry specifications for OEM calibration gases.
2. Integrity Calibration Gas Standards have a longer shelf life.  That’s what the Ideal Cylinder patent pending process is all about.  Which means you can keep a smaller inventory and save money, too.
3. We know what you need.  We are expert in both the manufacture of calibration gas standards and in the repair and maintenance of your gas detectors.
4. Every calibration gas cylinder is individually manufactured.  Standards don’t come in batches.  That’s why we make them one at a time instead of bulk transfers like resellers.

Here’s what OSHA has to say about the dangers of H2S:

Health Effects of H2S Exposure

Hydrogen sulfide is both an irritant and a chemical asphyxiant with effects on both oxygen utilization and the central nervous system. Its health effects can vary depending on the level and duration of exposure.  Repeated exposure can result in health effects occurring at levels that were previously tolerated without any effect. 

Low concentrations irritate the eyes, nose, throat and respiratory system (e.g., burning, tearing of eyes, cough, shortness of breath).  Asthmatics may experience breathing difficulties. The effects can be delayed for several hours, or sometimes several days, when working in low-level concentrations. Repeated or prolonged exposures may cause eye inflammation, headache, fatigue, irritability, insomnia, digestive disturbances and weight loss.

Moderate concentrations can cause more severe eye and respiratory irritation (including coughing, difficulty breathing, accumulation of fluid in the lungs), headache, dizziness, nausea, vomiting, staggering and excitability.

High concentrations can cause shock, convulsions, inability to breathe, extremely rapid unconsciousness, coma and death. Effects can occur within a few breaths, and possibly a single breath.

Route of exposure- as it’s called- is primarily through inhalation and not through the skin.  Also, H2S is somewhat heavier than air and it tends to collect in low-lying areas.  And if that isn’t enough, it’s a flammable has as well.

Olfactory fatigue is an issue with this gas as well, which means that a person can lose their ability to smell H2S even when it’s present.  This happens relatively rapidly.

For more information about the dangers of H2S, please see the OSHA H2S fact sheet at https://www.osha.gov/OshDoc/data_Hurricane_Facts/hydrogen_sulfide_fact.pdf  It’s well worth the reading.  OSHA does a great job of  providing important information to people about such dangers.
