About Hydrazine Detection

Hydrazine—also known as Diamine and Nitrogen Hydride—is a clear, colorless, flammable liquid, with an ammonia-like odor.

The compound is used in the production of agricultural pesticides; in the manufacture of blowing agents for plastic production; as an anti-corrosion agent in boilers and heating systems; in plating; in solders and fluxes; in textile dyes, during nuclear fuel processing; in explosives; in water treatment; and in photographic developing chemicals.

An additional use is in rocket fuel, and this application has generated the most interest in its detection as a toxic gas. Pioneering work to improve detection methods was started in the late 1970s at the School of Aerospace Medicine in Texas. Interscan is pleased to have been involved in these efforts, and continues to cooperate with NASA and similar agencies in other countries.

The related compounds monomethyl hydrazine (MMH) and unsymmetrical dimethyl hydrazine (UDMH) are also utilized in fuel applications.

Occupational Health/Toxicology

Hydrazine is corrosive and skin contact may cause burns and dermatitis. Inhalation and ingestion cause irritation of the respiratory and digestive systems, respectively. Exposure may also cause central nervous system health effects such as convulsions, tremors, lethargy, seizures, neuritis, and, in severe cases, coma. Long term exposure to hydrazine may cause liver, kidney, and reproductive organ damage.

An interesting case of accidental ingestion of hydrazine aboard ship in 1965 is discussed in this correspondence, to the British Medical Journal.

Fixed or Portable Gas Detectors: What Does Your Facility Need?

Fixed and portable gas detectors have different functions in industries. Fixed gas analyzers protect the facility and personnel by detecting accidental leaks and monitoring gas levels daily for compliance and process optimization. Portable gas analyzers protect individuals from exposure to hazardous gases in high-risk areas and jobs. The two systems’ use is not mutually exclusive.

How to Place Gas Detectors for Optimal Safety and Accuracy

Fixed sensors’ accuracy and reliability depend on optimal placement. Several characteristics of gases, such as point of origin, facility process, and equipment, must be considered to determine the location and placement of sensors. Industrial hygienists and safety managers should consult experts on gases, facility processes, and engineering to jointly determine the placement of fixed sensors.

Ensuring Accuracy in Gas Detection: The Importance of Wet Chem Calibration

Watch the video to see our wet chem calibration setup in action. At Interscan, we are committed to delivering precise and reliable gas detection solutions. One unique offering is the ability to calibrate gases that require wet chemistry. This article will explore wet chem calibration, why it is necessary, the process involved, and how we ensure our clients receive consistently accurate sensors. What is Wet Chem Calibration?

Is Fixed Gas Detection Necessary?

Yes, fixed gas detectors are necessary to provide continuous air monitoring for hazardous gases in stable and risky areas in workspaces without human intervention. Fixed gas detectors can be connected to alarm systems and building management software to provide crucial safety chain reactions, even without human intervention. Fixed gas detectors keep personnel safe and healthy, protect the facility, and help in regulatory compliance.

Gas Detection Applications Primer

Commonly Used Terms for Gas Detection Applications PPM: Part(s) Per Million A unit of concentration, pertaining to a gas mixture, defined as the ratio between the volume of an individual component V i and the total volume V total 10,000 parts per million equals one percent. LEL: Lower Explosive Limit The lowest concentration of a gas in air, which, when ignited, will sustain combustion.
