Ventilation and reorganization of the work environments, a very important theme and felt differently depending on the seasons and its climate.<\/h3>\n

– During winter, doors and windows are closed, resulting in smoke stagnation with poor ventilation and air exchange.<\/p>\n

– During summer or intermediate seasons, the ventilation problem is partially solved by opening doors, gates and windows, even if this is not possible at night or in case of rain.<\/p>\n

Let\u2019s start with the regulatory references<\/strong><\/p>\n

The Legislative Decree of 9 April 2008<\/strong>, known as Law 81<\/strong>, in Annex IV point 2.1.9.1<\/strong> clearly states that in premises or workplaces or in transit must be, as far as technically possible, the formation of dangerous or noxious concentrations of gases, exploding vapours or dusts, flammable, asphyxiating or toxic, shall be prevented or minimised<\/strong>; where necessary, adequate ventilation must be provided to avoid such concentrations.<\/p>\n

What are the objectives of general ventilation in production<\/strong><\/p>\n

Leaving aside offices or other premises, we want to focus on welding, grinding, painting or where fumes and dust are produced in high quantities. In this case the ventilation system must concentrate on the expulsion of stagnant fumes<\/em><\/strong>, assuming that the cloud of fumes in production, generally stagnates at a height between 4 and 7 meters from the ground.<\/strong><\/em><\/p>\n

Obviously the air flow helps to normalize the temperature during the heating periods, avoiding that the hot air stagnates at the top, with consequent benefits not only for the fumes but also to improve the microclimate in the workshop.<\/em><\/p>\n

Air recirculation yes or no?<\/h3>\n

The national reference legislation, DPR No. 303\/56 on workplace hygiene<\/strong>, does not clearly state whether or not air circulation in the workplace is possible.<\/p>\n

For sure in order to aspirate, filter and recirculate the air inside a workshop where there are fumes and dust is necessary to carry out a remediation project that uses the best available technologies and in any case it is not possible to recirculate in case there are very toxic pollutants.<\/p>\n

Solution 4.0 SECUREAIR: the ventilation system at work becomes “smart”<\/h3>\n

The project involves the ventilation of the rooms with aspiration and expulsion outside of the fumes and stagnant dust, carried out through wall fans<\/a> or roof extractors, with switching on and off automatically controlled by the AIRTRACKER<\/a> system.
\nHow it works
\nThanks to AIRTRACKER it is possible to monitor in real time the main environmental parameters of the air in the workshop and consequently to operate the ventilation only when necessary through a Wifi controller<\/a> that must be simply connected to the electric control panel fans.<\/p>\n

Why “smart”<\/strong> <\/em>
\n– Safe for workers, it is always activated in case of smoke.
\n– Also effective for summer ventilation, with room temperature control.
\n– Applicable in any business context to existing ventilation systems.<\/p>\n
