In the chemical and process industry, several gases are processed and stored, which can cause fire- and explosion hazards with possible leak- and high concentration situations.
According to standards, national and international rules describe the limits for alarms and operational controls within high concentration situations.
In the heating and power plants risk for fire and explosion hazard exists within leak- and high concentration situations. In soilid fuel processing the main risks are smoldering fires, fires or explosions.
These risks create serious and hazardous situations towards personnel, machinery and equipments.
In the dust explosion siruations there are risks for severe accidents, and even for death.
Propane, natural gas, ammonia and R-refrigerants are used in food industry processes and warehouses. Gas leaks are a significant risk factor and therefore attention has been paid to their reliable control.
Hazards are most commonly caused by technical faults in production equipment, tank leaks, transport and handling damage, operating errors and malfunctions.
Battery charging locations
There is a risk of hydrogen at the charging points of cordless trucks and sweepers.
During charging, explosive hydrogen gas (H2) is formed which, when mixed with air, forms an explosive mixture. The monitoring devices give alarms, control the enhanced ventilation of the room and also control the “charge-stop” functions.
The sensors to be installed at the charging points must mainly be Atex approved device types.
