Hidden Person Detection & CO2 Monitor

Hidden Person Detection

Security and border forces globally are deployed to search for stowaways. Our hidden person detectors are designed to measure changes in low levels of Carbon Dioxide and are implemented as an indicator of human presence.

Examples of Hidden Person Detection

There are a variety of circumstances where a stowaway or hidden person can pose a risk, which creates the need to be able to detect and locate them. Some examples of these cases are:

  • Border forces detecting stowaways attempting to cross international borders in shipping containers and large haulage trucks.
  • Search and rescue officers looking for signs of life in operations such as a building, cave, or mine collapse.
  • Prison officers searching for a potential escapee.
  • Deployment by police officers to detect human presence in a range of dangerous and/or hazardous situations.

How are Our CO2 Analysers Used for Hidden Person Detection?

Gas Data hidden person detectors are used by border forces to analyse Carbon Dioxide alterations in shipping containers and haulage trucks. They are also used by prison officers to analyse potential escapees and police forces to detect human presence in dangerous operations. Ancillary accessories are available to make their operations more effective.

Why Gas Data Instruments?

Gas Data’s Hidden Person Stowaway analyser measures CO2 up to 1%. That means a high level of accuracy in low concentrations. The GFM 226 has been designed to identify the presence of stowaways quickly and easily within confined spaces. The hidden person detector also incorporates an alarm feature to alert the user once a specified threshold has been passed.

CO2 Monitoring

Constant ventilation and control of carbon dioxide levels are two of the key aspects to reduce the risk of health problems, such as the airborne transmission of viruses. In indoor areas particularly, a large number of people exhaling and filling the space with CO2 can result in a build-up of the gas.

Why Monitor CO2?

The risk of transmitting a disease is increased in indoor environments and in areas where ventilation is poor. The UK government is advising businesses to adopt CO2 monitoring equipment in order to measure the effectiveness of ventilation within enclosed spaces.

In order to properly assess the effectiveness of ventilation in a particular area, the Health and Safety Executive (HSE) recommends deploying a CO2 monitor with a Non-Dispersive Infrared (NDIR) detector. According to the HSE, CO2 in outdoor spaces is approximately at a level of 400ppm and a well-ventilated indoor space should fall below 800ppm.

Why Use Gas Data CO2 Monitors?

Many businesses such as shops, offices, warehouses, restaurants, and pubs are often occupied by large groups of people. Although CO2 levels is not a measure of exposure to a virus, monitoring carbon dioxide levels using a gas monitor could help identify whether the space is sufficiently ventilated.

The CO2 gas monitor, known as the GFM 226, measures CO2 up to 10,000ppm. That means a high level of accuracy in low concentrations. The CO2 gas monitor also incorporates an alarm feature to alert the user once a specified threshold has been passed.
