chlorine dioxide – ClO2

Find here the essential information on chlorine dioxide (ClO2): characteristics, effects on health, detection devices & systems – ClO2 gas detector – and proper respiratory protective equipment (gas mask or powered air purifying respirator with B gas filter).

ClO2 gas detector and chlorine dioxide respiratory protection

Chlorine dioxide properties

Chlorine dioxide (ClO2) is exclusively an anthropogenic gas. This means that it cannot be found naturally. This synthesis produce is widely used in bleaching processes for paper pulp, flour, textile) and leather cleaning. It can also be applied for its biocide and disinfecting properties for many other applications like wastewater treatment, and is used in the pharmaceutical and food industries..

Chlorine dioxide effects on health

Chlorine dioxide (ClO2) taint varies from red-orange to green-orange. Its fragrance is irritating and smells like chlorine compounds. Non-explosive in the dark, it becomes unstable with light and can produce explosive mixture under the sunlight or with fast heating (R5). Very toxic by inhalation, it can cause severe burnings (R34). Soluble into water, it can form hydrochloric acid, which is very corrosive and harmful to aquatic organisms (R50).

Chlorine dioxide effects on health: why use a ClO2 gas detector

Chlorine dioxide effects on health (ClO2)

ClO2 gas detector - Chlorine dioxide

Despite its color and irritating smell, only a ClO2 gas detector can accurately measure chlorine dioxide gas concentrations. Moreover, even if this gas is explosive at 5.1% volume, an explosive capacity LEL monitoring would be useless with this highly toxic gas. It is thus recommended to use a ppm or ppb chlorine dioxide detection equipment.

Additional information

The GASBADGE PRO toxic gas detector is a classic single-gas detector. Its long-duration battery operates for about 2,600 hours and can be replaced when used. As for any other classic single-gas detectors, it is highly recommended to calibrate the GASBADGE PRO twice a year to ensure proper operation.

The GASBADGE PRO toxic gas monitor is a classic single-gas detector with interchangeable sensors and features a large range of electrochemical sensors. This technology is designed to detect toxic gases: Cl2 (chlorine), ClO2 (chlorine dioxide), CO (carbon monoxide), HCN (hydrogen cyanide), H2 (hydrogen), H2S (hydrogen sulfide), NH3 (ammonia), NO2 (nitrogen dioxide), O2 (oxygen), PH3 (phosphine) and SO2 (sulfur dioxide).

The GASBADGE PRO has 3 alarms: a powerful 95 dB audible alarm to alert even in noisy environments, a red LED visual alarm for view alert signals even in the darkest places like confined spaces and a vibrating alarm.

These alarms will be triggered by 4 events: if the lower or the upper limit values are reached, if concentrations get over the occupational exposure limit or if the average value threshold is exceeded. Abnormal gas concentrations and other data can also be saved and downloaded from the device.

Compact and lightweight, the GASBADGE PRO toxic gas detector is made with a strong polycarbonate housing with a robust and waterproof over-mold in compliance with IP67 protection. The GASBADGE PRO is ATEX approved as well for explosive atmosphere under current EU standards.

The MX6-iBrid gas detector is an high-tech portable multi gas detector. Thanks to its rechargeable ion-lithium (Li-ion) battery, it can operates around 24 hours continuously. The optional extended battery can replace the standard one and extend the autonomy up to 36 hours. A lighter version with AA battery is also available for 10 hours of operation.

The MX6-iBrid portable multi gas detector can detect up to 6 gases simultaneously according to the configuration (some locations are dedicated to specific sensors). A large range of gases is furthermore available: combustible gases, chlorine (Cl2), chlorine dioxide (ClO2), carbon monoxide (CO), carbon dioxide (CO2), hydrogen (H2), hydrogen cyanide (HCN), hydrogen chloride (HCl), hydrogen sulfide (H2S), nitric oxide (NO), nitrogen dioxide (NO2), ammonia (NH3), oxygen (O2), phosphine (PH3), sulfur dioxide (SO2) and many volatile organic compounds (VOC).

The MX6-iBrid combines the highest sensor technologies for accurate measures. Oxygen and toxic gases are detected with an electrochemical sensor. Combustible and explosive gases are on the other hand detected with a catalytic sensor or through infrared absorption. This IR technology is also used to detect carbon dioxide. Lastly, volatile organic compounds are detected with a photoionization sensor (<10,6 eV).

This portable multi gas detector is considered as a high-technology device as it is the first portable gas detector featuring a colored display. This allows users to easily read events curbs of every gas without misunderstanding. The MX6-iBrid is compliant with the most demanding ATEX standards and with the IP67 ingress protection level thanks to its shock-resistant polycarbonate overmolded housing.

Chlorine dioxide respiratory protection (ClO2)

As chlorine dioxide is irritating to the eyes, it is advised to wear a full-face mask for short- term interventions or a much more comfortable powered air purifying respirator equipped with a B filter for longer applications. If concentrations exceed 60 times the OEL, a self- contained breathing apparatus (SCBA) is required for better safety.

The Duraflow powered air respirator is a versatile solution for hazardous workspaces. It provides a quality respiratory protection for a fair price.

  • The powered air purifying respirator Duraflow PAPR
  • Compatibility with RD DIN 40 universal filter cartridges
  • Rechargeable battery – 2 available version: 8 or 16 hours runtime
  • Automatic airflow regulation (160l/min)
  • Visual alarms, notifications and display
