Description

DESCRIPTION

DEVICE FOR CONTROLLING THE SAFETY HITCH ON THE

WORK AT HEIGHT

TECHNIQUE SECTOR

The invention falls within the sector of safety devices that are required to work at height, whether in construction, platforms, scaffolding, structures, etc. Works from a height of 1.80m, which require the use of a fall prevention and arrest device, such as: Anchorage, anchor line, life line and safety harness. We can refer to the Technical Note on Prevention NTP1.170 of the year 2022 issued by the Ministry of Labor and Social Economy, which describes the need and obligation to use said individual safety devices against falls from a height.

BACKGROUND OF THE INVENTION

Law 31/1995, of November 8, on the prevention of Occupational Risks, sets out the general framework in which the different preventive actions will have to be carried out, in coherence with the decisions of the European Union, which has expressed its ambition to progressively improve working conditions and to achieve this objective of progress with a gradual harmonization of these conditions in the different European countries.

In compliance with the duty of protection, the employer must guarantee the safety and health of the workers at his service in all aspects related to work. For these purposes, within the framework of their responsibilities, the employer will carry out the prevention of occupational risks by integrating preventive activity in the company and adopting as many measures as are necessary to protect the safety and health of workers. . It will develop a permanent action to monitor the preventive activity in order to continuously improve the identification, evaluation and control activities of the risks that could not be avoided and the existing levels of protection and will provide what is necessary for the adaptation of the prevention measures that may experience the circumstances that affect the performance of the work. The employer must comply with the obligations established in the regulations on occupational risk prevention, among others by providing individual protection elements. necessary (PPE) to ensure that work is carried out safely.

The obligations of the workers established in this Law, the attribution of functions in the matter of protection and prevention to workers or services of the company and the recourse to the agreement with specialized entities for the development of prevention activities will complement the actions of the employer, without therefore, they exempt him from the fulfillment of his duty in this matter, without prejudice to the actions that he may bring, if applicable, against any other person.

Currently in construction sites and especially in work at height, there are many passive safety elements, such as harnesses, life lines, helmets, etc... but there are no devices that guarantee that these elements are being used at all times. moment by the workers.

Each location with a risk of falling from a height is characterized by specific circumstances that must be taken into account and as a consequence using a combination of a different type of harness, sling or rope and hitch adjusted to the circumstances, it is not the same to work hanging from a pole, than working on a platform at height or near edges, or working on a scaffold, or on decks, etc. In each case, the fixing to the fixed point can be variable, but what is always required is that the coupling be carried out, and this control is the one that is usually difficult, if not impossible, to be verified by the person in charge of the work, or employer. of the worker, who is not in situ to verify it, however said difficulty of verification does not prevent him from being criminally responsible for the consequences of a possible accident.

There are a multitude of individual safety devices against falls that are in turn regulated by the corresponding UNE standards and that in turn refer to each of its parts or components, all of them forming part of the state of the art, and thus we can refer to the rules:

- UNE-EN 353-1:2014+A1:2017 “Individual protection equipment against falls from a height. Sliding fall arrest devices on rigid anchor line”.

- UNE-EN 353-2:2002 “Individual protection equipment against falls from a height.

Sliding fall arrest devices on flexible anchor line”.

- UNE-EN 354:2011 “Individual protection equipment against falls. Teams of moor”.

- UNE-EN 358:2018 “Personal protection equipment for support in the work position and prevention of falls from a height. Belts and lashing equipment for work positioning or retention.

- UNE-EN 360:2002 “Individual protection equipment against falls from a height.

Retractable fall arrest devices”.

- UNE-EN 361:2002 “Individual protection equipment against falls from a height.

Fall arrest harnesses”.

- UNE-EN 362:2005 “Individual protection equipment against falls from a height.

Connectors”.

- UNE-EN 795:2012 “Individual protection equipment against falls. anchoring devices”.

- UNE-EN 1497:2008 “Individual protection equipment against falls. Rescue harnesses”. UNE-EN 1498:2007 “Individual protection equipment against falls. Life-saving ties”.

There are more standards related to these individual protection devices or equipment against falls from a height, all of them describe some characteristics of the device, but none of them refers to the control of the safety hitch in said works at height. with the risk that this implies, since the equipment is available, but if it is not put into operation, that is, if the hook to the fixed point is not made, no matter how much harness and sling or line with carabiner is available , and it is carried collected or tied to the waist of the harness or individual, the security that these devices have as purpose is not obtained, and what is more serious, if possible, the responsibility in the event of a fall may fall on the user. employer, for not having ensured the correct use of security measures by the worker.

The object of the present invention, as explained below, is a device for controlling the safety hitch in work at height, but in an integral way and through IoT (Internet of Things), that is, with identification, location, mobility, aid or assistance, etc. the device provides traceability, increases the use of individual protection elements, the geolocation of the person, keeping all the data recorded on a computer platform.

EXPLANATION OF THE INVENTION

The present invention is a device for the control of the safety hitch in work at height that, incorporating IoT technology and being installed in the sling or rope between the safety harness and the life line or other fixed element, shows us when the worker is tied up or not, thus ensuring the use of prevention measures at height and most importantly, the lives of people. The device also includes a help or assistance button in case the person needs external assistance (rescue or health care).

It is a basic help for the prevention services of the companies and guarantee the safety of the workers, the accident rate is reduced and therefore lost working hours, with greater productive efficiency.

The device object of the invention is placed in the sling or rope that joins the worker's harness and the lifeline or other fixed element, monitoring whether the safety harness is in use or not. So it is constantly known whether or not the worker is protected against falls from a height.

This device emits signals 24/7 that are picked up by other devices, such as smartphones, computers of all those people who must know if security measures are being used, indicating at all times if the worker is tied up or not, as well as all the traceability is recorded in the system.

Each device is assigned to a person by name, with a QR code or with a barcode. In this way, the system identifies each person with a single device, reporting their geolocation, the height at which they are located and whether or not they are tied.

In addition, each device has a button or mechanism for activating the call for help or assistance. This possibility is very useful when a person who is working at height and is alone, if he needs medical or rescue assistance, simply by pressing the button he can be helped. This help or assistance button can be activated by the worker himself or, if there is no activity for a certain period of time, automatically, the Artificial Intelligence with its IoT activates it for this device.

This device and the system associated with it increase the safety of workers and facilitate the management of occupational risk prevention. Prevent, record the use of prevention elements and ensure the help of a person when needed.

The device as described below has a technological development combining accelerometers, altimeter, magnetometers and geolocator, as well as a GPS transmitter.
