Hazardous Area (HA)
It is an electronic safety system that may reduce risks and accident rates. The HA automatically stops a machine from working when personnel with a safety tag is near the area indicated as “danger zone" or when a person falls onto a conveyor belt. This system indicates the entry of a person and will stop all activities, therefore avoiding accidents or damages.
The HA Solution automatically prevents a computer, such as a crusher, when a person with the corresponding tag enters the area marked as a "danger zone" or when a individual falls inside a conveyor belt, likely as a result of being knocked off, fainting or similar.
This solution creates a secure protocol that specifies that all action must stop upon entry of a individual thus preventing injuries or damages.
The device is responsible for detecting when an operator-carried safety tag reaches the area configured as a "danger zone." In that case the computer mounted there and specially designed under this solution is stopped immediately. The contact between the key ring of the staff and the mounted antenna-whether it is in a crusher, compactor or some other similar machine-is automatically created without the need for permanent human control. It offers greater protection in areas which are typically particularly vulnerable to workplace injuries.
The device also records the date and time the computer stopped, as well as the number of tags found in the danger zone, in order to enforce protection measures in this respect and in the future to prevent similar situations. Furthermore, this approach provides the possibility to check that the device is operational as an essential condition for secure working within the perimeter of the unit.
The HA device is designed primarily for use in areas containing pits, presses, crushers or compactors, among other extremely dangerous devices. It is also sometimes used in areas surrounding broad conveyor belts.
The HA system consists of the units:

System that offers traffic lights to forklift drivers that warns them when there are pedestrians crossing
Informs pedestrians and forklift operators in situations of dangers by projecting symbols on the floor
The Low Speed Area solution (LSA) places a limit on the speed at which a forklift circulates through different areas.
