ICP - Autoridade Nacional de Comunicações (ICP – National Communications Authority)
Rules governing the identification and signalling of radiocommunication stations
Radiocommunication stations emit non-ionising radiation, thus being required, according to Decree-Law no. 11/2003, of 18 January, to comply with the reference levels set out in law for the purpose of the assessment of exposure to electromagnetic fields.
Without prejudice to this obligation, Decree-Law no. 151-A/2000, of 20 July, lays down in paragraph 2 of article 21 that in places where fixed radiocommunication stations and respective accessories, i.e. aerials, are installed, signs indicating the risks of the referred installation must be displayed.
Decree-Law no. 11/2003 of 18 January provides alongside, in paragraph 4 of article 11, that ICP - Autoridade Nacional de Comunicações (ICP – ANACOM) may adopt measures constraining the installation and functioning of radiocommunication stations.
In this context, as this subject-matter may potentially be of concern to populations and local authorities, ICP-ANACOM hereby defines that aerials, structures supporting them and respective places of installation must duly bear signs indicating the levels of radiation emission and the degree of hazardousness, if any, to populations close to these infrastructures. Likewise, the placing of appropriate fences that do not allow for a contact with aerials within reach is also provided for.
An additional concern for ICP-ANACOM is to ensure that fixed radiocommunication stations bear the identification of the respective user, as well as means of contact with the person responsible for granting access to the facility.
In fact, this obligation was imposed by Decree-Law no. 151-A/2000 [paragraph h) of article 10], nevertheless it was necessary to define the places where identification signboards were placed, and their characteristics, thus making the obligation practicable.
Therefore, pursuant to paragraph 1 c) and h) of article 6 and to article 9 a) of its Statutes, approved by Decree-Law no. 309/2001, the Board of Directors of ICP-ANACOM hereby approves the following regulation:
Purpose and scope
1. This Regulation aims to lay down rules governing the identification of fixed radiocommunication stations and information signs in places where the referred stations and respective accessories, namely aerials, are installed.
2. Rules herein apply to all fixed radiocommunication stations, including those referred to in paragraph 2 of article 1 of Decree-Law no. 151-A/2000 of 20 July.
3. Rules established in chapter III hereof do not apply:
a) To radiocommunication stations that integrate the license exempt networks and license exempt radiocommunication stations, identified in both cases in the National Frequency Allocation Plan (NFAP);
b) To single radiocommunication stations assigned to the Amateur Service;
c) To radiocommunication stations assigned to the Personal Radio Service (CB);
d) To radiocommunication stations onboard aircrafts or vessels and subject to specific law;
e) To radiocommunication stations referred to in paragraph 2 a) of article 1 of Decree-Law no. 151-A/2000 of 20 July;
f) To radiocommunication stations, the specific nature of the purposes to which they are assigned, namely security, advises against the placing of the respective identification signs, which must be defined on a case-by-case basis by ICP-ANACOM.
1. The definitions in Decree-Law no. 151-A/2000 of 20 July apply hereto.
2. Specifically for the purposes hereof, the following definitions apply:
a) Symbol or pictogram means a figure which describes a situation or prescribes specific behaviour and which is used on a signboard or illuminated surface;
b) Signboard means a sign which provides specific information by a combination of a geometric shape, colours and a symbol or pictogram.
Signalling of stations
1. Where aerials are within reach, without resorting to auxiliary means and/or climbing masts and poles, appropriate fences must be placed that do not allow for a contact therewith by the population.
2. The inaccessibility to conductive objects must be ensured, if appropriate by placing appropriate fences, where the reference levels for contact currents, set out in Administrative Rule no. 1421/2004, of 23 November, approved under paragraph 1 of article 11 of Decree-Law no. 11/2003, of 18 January, are not guaranteed.
3. Fences are compulsory to define boundaries where reference levels set out in the Administrative Rule mentioned in the preceding paragraph may be exceeded.
1. Aerials, structures supporting them and places where this equipment is installed must bear due signs, using five signboard models, as well as supplementary ground signs, where appropriate, specified in the annex hereto, which is an integral part hereof.
2. Signboards shall comply with the format and pictogram characteristics indicated in the annex, which may vary somewhat relatively to the figures provided for, insofar as these differences or adaptations do not obscure the respective meaning.
3. Signboards are to be made of shock and weather-resistant material suitable for the surrounding environment.
4. The colorimetric and photometric features of signboards must be such that they can be easily seen and understood, dimensions varying between A2 and A10 formats. The chosen format shall be appropriate to the specific situation of each element to be marked, bearing in mind that it must be perfectly visible to the target-population.
Locations to place signboards
1. According to provisions defined in articles 6, 7, 8 and 9, information signboards must be placed:
a) In fences;
b) In the gateway(s) to the interior of compartments where the equipment necessary to the constitution of radiocommunication stations is installed;
c) In the body of the aerial, or where this is not practicable, close thereto, in case they are placed in masts, poles, walls or roofs;
d) In areas of access to locations where aerials have been placed.
2. In alternative to the placing of information signboards, signs in self-adhesive or painted form may be used, provided that they comply with requirements established in the preceding paragraph.
3. Signboards are to be installed in a visible location, at a suitable height and in an appropriate position, taking account of any obstacles to the line of sight, so as to ensure adequate conditions to the readability of messages.
4. The use of signboards shall take account of the location where they are placed and the power density levels in the marked places.
5. The number and placing of signalling means or devices will depend on the configuration and extent of the area to be covered, ensuring an appropriate readability.
General rule for placing signboards
1. A signboard displaying the word “Attention”, identified as model 1, must be placed in fences, compartments and aerial support structures, except where in cases expressly identified herein a different sign is required. In alternative to model 1, model 3 may be used.
2. A signboard displaying the word “Danger”, identified as model 2, must be placed next to any aerials, even if disguised or not visible, and wherever practicable, such signboards shall be placed on the body of the aerial.
3. The signboard placed in compliance herewith must be removed when the situation to which it refers ceases to exist.
1. Where, in places mentioned in paragraph 1 of article 5, the levels of electromagnetic fields exceed by -10 dB the reference levels set out in Administrative Rule no. 1421/2004, of 23 November, the following signs must be placed in the boundaries where such levels occur:
a) Where levels remain in a range between -10 dB and -5 dB relatively to the reference levels set out in the above-mentioned Administrative Rule, a signboard displaying the word “Attention”, identified as model 3, must be placed;
b) Where levels are higher than -5 dB relatively to the reference levels set out in the above-mentioned Administrative Rule, but do not exceed them, a signboard displaying the word “Warning”, identified as model 4, must be placed;
c) Where reference levels set out in the above-mentioned Administrative Rule are likely to be exceeded, a signboard displaying the word “Danger”, identified as model 5, must be placed.
2. The means to calculate the relations referred to in this article are provided for in Administrative Rule no. 1421/2004 of 23 November.
1. Without prejudice and in addition to the signs provided for in article 7, where, in a place accessible to the population, the levels of electromagnetic fields are not lower at least by 10 dB relatively to the reference levels set out in Administrative Rule no. 1421/2004, of 23 November, supplementary signs must be placed.
2. Supplementary signs bear yellow and black stripes of similar surfaces, placed on the ground, preferably as stripes with an angle of 45º, together with a black over yellow pictogram, as described in the annex hereto.
3. The positioning of supplementary signs shall take into account the dimensions and features of the place to be marked, as explained in the annex hereto.
4. Signs provided for in the preceding paragraphs need not be placed where the access to locations is limited to a restricted number of persons who are aware of the environment conditions to which they are subject, by means of other signs provided for herein.
Set of stations
1. Where there is a high congestion of stations and respective accessories, namely aerials, preventing or hindering the placing of individual fences pursuant to article 3, ICP-ANACOM is entitled to determine the placing of a fence or the adoption of a different measure that inhibits the access by the population to the area where levels of power density justify this measure.
2. In areas of access to places referred to in paragraph 1, namely building terraces or roofing, a signboard displaying the word “Warning”, identified as model 4, must be placed, in this case the placing of signboards displaying the word “Attention”, referred to in paragraph 1 of article 6, not being required.
Limited and prohibited access to installation locations
1. In cases provided for in paragraph 1 b) of article 7, access thereto by the population is conditional upon escort by authorized staff.
2. In cases provided for in paragraph 1 c) of article 7, access thereto by the population is prohibited.
