ICT & Environment Seminar Safety and Environment Aspects for Outdoors Installations

ICT & Environment Seminar • Ronaldo Arruda • ITU-T –SG-6 Rapporteur Q.2/6 • Cairo –Egypt • 4-7 October 2004 • r.arruda@ties.itu.int

Topics • Outdoors Installations. • Safety and Environment Proceedings • Olds and New installations

ITU-T –Vision • Promote the develpment, expansion and operation of telecommunication networks and services particulary in developing Countries • Encourage participation by industry in telecommunications development in developing countries and offer advise on the choice and transfer of appropriate technology

ITU-T Mission • Is to ensure na efficient and on time production of high quality standards coverig all fields od telecommunications

Activities of ITU-T Related to the Outside Plant • Study Group V-Protection of Telecommunication Against Eletromagnetic Interference. • Study group VI-Outside Plant

Activities SG-V • EMC and safety aspects of telecommunications networks • Envorinmental and Characterization and health effects to mobile and radio systems

Activities-SG-VI • Strategies to prevent accidents in unattended enclosures associated with outside plant elements.

Activities SG-VI • Environmental aspects resulting from outside plant material recycling.

Outdoors Installations • Ducts Systens • Manholes • Aerial Networks • Equipments in outside plant • Share Infraestructures • Sewages Infraestrutures

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

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;

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

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

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

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;

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.

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.

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;

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 .

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 .

News Concepts on Networks • CATV • WI-FI • FTTH • FTTO • LAN • WAN

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.

Distances Between TLC and Power Networks

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.

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.

Results • SG-5 - 64 Recommendations • SG-6 - 62 Recommendations

Conclusion • We have a lot of Recommendations ,the problem is , • to use
