Hydrazine – N2H4

Find here the essential information on hydrazine – N2H4) or diazane: characteristics, effects on health, detection devices & systems – hydrazine gas detector – and proper respiratory protective equipment (gas mask or powered air purifying respirator with K-P3 combined filter).

Hydrazine properties

Best known for its use as rocket jet fuel, hydrazine (N2H4) – also known as diazane – is also used in the petrochemical and pharmaceutical industries as a synthesis intermediate and in the rubber industry as a blowing agent to produce polymer foam. Thanks to its characteristics – mainly its liquid state at ambient temperature – this gas is used to produce fuel cells.

Hydrazine exposure hazards

Colorless and featuring an ammonia smell at low concentration levels, hydrazine (N2H4) is very soluble into water or alcohols, which may lead to explosive vapors production. Even if it is flammable either liquid or gaseous (H226), this gas is very toxic if inhaled, swallowed or in contact with skin (H331/301/311) and classified as 2B (possibly carcinogenic to humans) by the IARC*. It can cause severe skin burns and eye damage as well (H314).

Hydrazine gas detector - N2H4

As this gas is not detectable through smell, only a hydrazine gas detector can accurately measure concentrations of this gas. Moreover, even if this gas is very explosive (at 1.8% volume), its explosivity monitoring would be pointless as hydrazine is toxic. For this reason it is recommended to use a portable or fixed hydrazine detection equipment.

Additional information

Volatile organic compounds – most commonly known as VOCs - gather thousands of substances and gases. They can be found in many fields of activity. The MX6-VOC gas detector is a classic single-gas detector especially designed to detect these substances. Thanks to its ion-lithium rechargeable battery, it can operate during 12 hours according to the application.

The MX6-VOC gas detector needs to be calibrated twice a year in order to ensure proper operation. The photoionization sensor (sensor technology for VOC detection) can detect volatile organic compounds with a ionization potential below 10.6 eV. The MX6-VOC measuring range is set between 0 and 2,000 ppm in 0.1 ppm increment.

An integrated gas sampling pump guarantees measurements accuracy. This pump also enables to draw remote samples before intervention. According to the configuration, it is possible to add up to 5 more gases to the MX6-VOC.

This VOC detector features 3 different alarms. The powerful audible alarm is designed to alert even in noisy environments. The high visibility red LED visual alarm and a vibrating alarm are also made to ensure a high level of protection.

Its large colored screen displays concentrations in ppm (part per million) or in percentage volume. Digital values can be replaced visually thanks to the user-friendly menu.

The MX6-VOC gas detector is impact-resistant thanks to an over-molded polycarbonate housing. This monitor meets almost any EU current gas detection related standards.
