About GDI

What is Gas Detection?



Fixed gas detection systems are installed with the aim of providing continuous, area and personnel protection around the clock. These detection systems are designed to alert workers of the potential danger of poisoning by toxic gas exposure, asphyxiation due to lack of oxygen or explosion caused by combustible gases.

The installation of a gas detection system will help to reduce health and safety risks and create safer working environments. Indeed, the installation of monitoring systems are often stipulated in order to secure adequate insurance cover and compliance with local health and safety and explosive atmosphere regulations, applicable in your territory.
