Risks at work

The innovation of Gerotto's Mini Robot Excavators at the service of workers' safety.


Gerotto Federico S.r.l. has a long experience in working in confined spaces and explosion risk areas: for this reason it has made safety its mission, designing and implementing innovative solutions, able to minimize the operators exposure to hazards at work.

The daily commitment of the technical office has led to the development of equipment to safeguard the health of those who access risky environments, which result in:

- robotic solutions which, together with vacuum and suction technologies, allow the removal of material and debris inside confined spaces;

- ATEX certified, explosion-proof products for working in environments with potentially explosive atmospheres;

- video-inspection and remote control systems for the Mini Robot Excavators, that can be integrated in all the machines;

- increasingly smaller robots to reach places where men cannot arrive;

- multiple accessories to be attached to the Mini Excavators for breaking up and collect the most diverse materials, in complete autonomy. 


"Confined spaces" is the definition of those closed places where man entry is not normally planned, but which nevertheless present extremely limited entry passages that make access possible for man in case of extraordinary interventions.

They are very narrow or almost completely closed places, where man entry have to strictly follow the applicable regulations.

The main risks faced by workers in confined spaces are:

- lack or excess in oxygen;

- possible presence of harmful exhalations (dangerous gases, fumes or vapours) that can cause poisoning;

- burns caused by contact with materials at too high or too low temperatures;

- explosions or fires, caused by the presence of flammable substances;

- injuries due to falls, cutting wounds, slips, crushing, impacts, etc.

All of these risks get worse by the fact that, because of the limited spaces, it is not possible to easily move nor to quickly provide help: it is therefore necessary for workers to equip themselves with all the safety equipment, to have adequate training and to be in good physical conditions to perform their activities.


The word ATEX comes from the French words “ATmosphères EXplosibles”, that means Explosion Proof and it refers to the European Union directive Nr. 34, became effective on the 30th of March 2014. This directive regulates the usage of equipment in explosion risks zones or in areas with potentially explosive atmospheres.

Any tool or machine to be used inside these areas must have a compliancy certification, in order to guarantee the essential requirements for safety.

ATEX zones, which are hazardous for the presence of flammable gases, vapours or mists, are classified into three categories following the IEC classification system:

- Zone 0: area where the explosive atmosphere is present continuously or for long periods of time (or, in any case, for more than 1000 hours/year).

- Zone 1: area where the explosive atmosphere is likely to exist under normal operating conditions and it may exist frequently (between 10 and 1000 hours/year).

- Zone 2: the concentration is not likely to occur during normal operation (less than 10 hours/year); it occurs for only a short period of time and becomes hazardous only in case of an accident or some unusual operating condition.
