Microbial Air Samplers are used in Zone 2 - Explosion Hazard areas (II 3G Ex iC IIC T4 Gc IP55)
In some pharmaceutical and food premises the sampling and analytical instruments may operate in production areas and warehouses
where are present inflammable material in form of gas, vapour, fog or mist. An explosive atmosphere may be created in presence of
such substances and produces an inflammable mix, in case ignition occurs.
The instruments that operate in such environments need to meet the stringent International Directives referred as ATEX (Atmosphere Explosive) directives which are adopted to protect health and safety in the workplace when there are risks due to the presence of potentially explosive atmosphere.
EXPLOSION RISK IN PHARMACEUTICAL INDUSTRY
Compressed gases and solvents with specific explosive characteristics are processed during industrial production can be released into the air. The same phenomenon can happen in the analytical laboratory in presence of solvents.
A dangerous explosion occurs when the combustible dust comes into contact with an ignition source like electrostatic discharge, mechanical overheating or chemical reactions or heat from the surrounding surfaces.
EXPLOSION RISK IN FOOD – AGRO and BEVERAGE INDUSTRY
The dangers of dust explosions in food and beverage plants have been well publicized, but devastating accidents still take place far too often. Almost a quarter of all reported industrial dust explosions occur in the food and beverage industry. There are hazards that need to be controlled, such as those from flammable gas (fuels for ovens), flammable liquids and vapours (spirit based flavourings and cooking/coating oils).
