How often, especially while working, do we find ourselves in an environment where there is no electricity at all? With modern technological development, this possibility is practically unthinkable, even if, in the presence of an electrical power source, the risk of being electrocuted is always present. This unpleasant and painful eventuality, when it is present in the workplace, is called an electrical risk: a danger that can vary in magnitude, but which is more or less present in most workplaces.
How do you protect yourself against electrical risks?
It is advisable, and in many cases mandatory, to wear appropriate protection when systematically exposed to electrical risks. This is why many professionals’ uniforms often include PPE footwear with Antistatic or ESD (electrostatic discharge) certification.
These designations, which both indicate the device’s ability to protect against electrical risk, differ in one very significant detail:
- Antistatic (A) means that the PPE’s priority is to disperse electrostatic charges by preventing them from accumulating on the surface of the shoe itself, thus avoiding the sudden transfer of electricity from an electrically charged object to the operator’s body: in other words, it prevents the user from being shocked by coming into contact with electrically charged objects.
- ESD, on the other hand, means that the PPE, the footwear in this case, constantly discharges energy to the ground, protecting not only the operator, but also the machinery he uses and with which he comes into contact. In fact, some electronic equipment is at risk of damage if the right preventive measures are not taken, as it is sensitive to electricity and may be damaged by electrical discharges.
An ESD device is designed to protect both the person wearing it and the machinery being used, whereas an A-marked accessory only protects the operator.
Speaking of footwear, antistatic footwear has an electrical resistance ranging from 100 KiloHom to 100 MegaHom, while ESD footwear has a range from 100 KiloOhm to 35 MegaOhm.
It means that ESD footwear is also antistatic, whereas antistatic shoes are not always ESD.

Upgrade of the Reposa sterilizable line
The electrical risk, even though to varying degrees, is a danger that is transversally present in many workplaces, because electrostatic charges are not only generated in the presence of a power source. The easiest way to generate electricity is by rubbing two materials together: simply unrolling or handling plastics such as PVC creates an accumulation of electrostatic charges capable of generating a shock, as well as walking on synthetic floors with synthetic shoes on your feet, as most of them are.

How can the ESD be a plus value?
ESD footwear differs from more common anti-static footwear in its dissipative capacity, which constantly discharges electrical charges to earth, preventing them from accumulating.
To give the clogs this property, a hi-tech rubber plug has been designed and inserted into the sole. The advantages of these enhancements:
- Resistance to time: while the anti-static properties are often subject to variability and usage, as a result of use, maintenance and washing, the plug is perfectly incorporated into the sole and is imperceptible to the wearer and when walking.
- Safety: even the position of the plug is not random! It is located at the height of the metatarsus, which is the point of more contact between the foot and the ground.
- Performance: this innovation improves and stabilizes the anti-static values, giving the clog ESD properties.
This technology applies to the Reposa sterilizable clog line, which has recently been upgraded, and to the ultra-light shoe Reposa Smart, which was already designed with ESD.
