Gas detector OLLI
A good gas detector is essential for safety in various situations, such as installation work, industrial work and manhole inspections. The OLLI is an excellent example of a reliable certified gas detector, especially for confined space entry. This advanced device not only detects flammable gases (ex) but also toxic gases (ox) and immediately triggers an alarm in the event of dangerous gas concentrations. This ensures a rapid response and minimises exposure to hazardous gases.
Gas measurements in confined spaces
Gas measurement in enclosed spaces is crucial for recognising potentially dangerous gas concentrations and protecting employees from the risks posed.
Portable measuring device
A portable gas detector offers mobility and real-time alerts, which is essential for safety in challenging environments and emergency situations.
Detection of gas leaks
A gas leak detector offers proactive protection by detecting and localising gas leaks and thus reducing safety risks.
Gas stations
A gas detector constantly monitors the air to detect dangerous concentrations and thus reduce risks and ensure safety.
Everything about the OLLI
What is a gas detector?
A gas detector is a measuring device that is used to detect and measure the presence of certain gases in the environment. It is task to monitor air quality and provide early warning of potentially harmful or dangerous concentrations of these gases, which is essential for industrial safety and environmental protection.
What does a gas detector measure?
A gas detector measures certain gases in the environment to detect potential safety hazards. These measurements typically include the concentration of harmful gases such as carbon monoxide, hydrogen sulphide or flammable vapours and issue warnings if these levels exceed preset thresholds. A modern gas detector can also measure environmental factors such as temperature, humidity and air pressure to improve the accuracy of gas measurements. These devices are critical in industrial, residential and commercial environments to ensure safety and minimise potential hazards.
What is a good gas detector?
A good gas detector is essential for safety in various situations, such as installation work, industrial work and manhole inspections. The OLLI is an excellent example of a reliable, certified gas detector. This advanced device not only detects flammable gases (ex), but also toxic gases (ox) and immediately triggers an alarm in the event of dangerous gas concentrations. This ensures a rapid response and minimises exposure to hazardous gases.
How does oxygen deficiency affect humans?
Normally, air contains about 20.9 per cent oxygen by volume, which is essential for normal human respiration. However, an excess of oxygen can accelerate the ignition of other materials and fuels and speed up the oxidation of most substances. On the other hand, a lack of oxygen in humans can lead to respiratory distress, and with very little or no oxygen, it can even be fatal.
| Oxygen concentration | Effects |
|---|---|
| 19,5 % | Breathe normally. |
| 19,5 – 14 % | Immediate danger, find a safe place immediately. |
| 14 – 12 % | Deep breathing, increased pulse, poor coordination. |
| 12 – 10 % | Faster and shallower breathing, dizziness, disorientation and blue lips. |
| 10 – 8 % | Nausea, vomiting, unconsciousness and deathly pale face. |
