11. Class of Environment
Class A: environment with the floor in wet conditions, sometimes with standing water (for example, manholes, vaults, trenches);
23/11/2018

12. Class of Environment
Class B: environment with wet walls and confined working space (for example vaults) such that the wet wall may be in contact with the persons body and producing a current path different to the hand-to-feet current path;
23/11/2018

13. Class of Environment
Class C: environment with confined working space and existing extraneous metallic parts (for example facilities of other services); during the operations, large area of the metallic parts are in continuous contact with the body
23/11/2018

14. Networks Projects
To be in hands the complete project of all the existing installations in the place, type of land, adequate material of security, signalling, models of typical shoring and mechanicals equipaments
23/11/2018

15. Ducts systens
In the construction or maintenance of duct lines it must first be analyzed the projects observing rigorously all the procedures of security demanded by the a administration of the workmanship and a total knowledge of that this installed
23/11/2018

16. Manholes
When of the opening of manholes it must be had the following cares at the very least:
when opening the manhole to observe its inside presence of water, gasoline, fuel, etc;
23/11/2018

17. Cables Tunels
The systems of security normally are -smoke and fire and control by detectors, fire extinguishers, and gas detectors that are installed to long of the tunnel and the galleries.
23/11/2018

18. Cables Tunels
Recommended that the set in motion detection systems electrically are projected to act through chain continues and with low voltage in the direction of if preventing some risk of explosion, mainly for the possibility of the existence of gases in the tunnels.
23/11/2018

19. Terminal Box -Devices
Electrical measurements: it is required that the measurement instruments and their accessories have an insulation level adequate to the expected voltages present on the telecommunication line;
Maintenance by removal or insertion of components directly extractable;
23/11/2018

20. Aerial Networks
In the crossings of telephone networks and electrical power networks of up to 70 kV, must be observed a 90º±15° angle.
In the crossings of telephone networks and electrical power networks with voltage between 35 kV and 70 kV, the messenger must be grounded in both sides of the electric line, with a maximum ground resistance of 30 .
23/11/2018

21. Aerial Networks
Is not recommended the installation of telephones cables in infrastructure of electric power with voltage higher than 75 kV.
It is not recommended the project of telephones networks in parallel lines with electric power networks with nominal voltage higher than 35 kV.
The ground resistance must be the maximum of 13 .

23. Share Infraestructures
In the case of share infraestructure e.g, water canalization, oil, gas, energy it must be looked for to observe the demanded procedures of safetyy for each in case and, mainly observing the proceedings demanded for each administration.

25. Personnel Safety
A person having appropriate technical training and experience necessary to be aware of hazards, to which that person may be exposed in performing a task, and of measures to minimize the risks to that person or other persons.
23/11/2018

26. Safety Alert
All the safety procedures should be used independent of kind of service,e.g, splice,cables launch , type of land,and control of signalling of the performance of the worker when of its in the intervention.
