Combined booths shall be provided with a minimum of two permanently accessible and normally non-lockable doors placed as far as practically possible apart from each other. Also when the booth is loaded the operator shall not have more than 10m to travel in order to reach at least one of these doors. If the booth-loading door can be opened by a mere push from the inside only one additional personnel door shall be required. If the longest wall is less than 5m a single door is considered to be sufficient. Power-operated doors as well as vertical and horizontal sliding doors cannot be considered as personnel door. Power-operated doors shall comply with EN 12433, EN 12445, EN 12453, EN 12635 and EN 12978. In addition the length and width of combined booths shall be a minimum of 1m on each side than of the biggest item to be painted. SIST EN 13355:2005+A1:2009

Protection against burns by hot surfaces shall be secured by means of appropriate insulation or protection against contact of all elements within arm’s reach and within the working area. According to EN 563 at an ambient temperature of 20 °C the surface temperature shall be less than 60 °C. Exceptions are permissible in small localised areas of the surface (for example flanges of burners, bolts, fan and roller shaft). NOTE For safety of hot spraying systems, see EN 1953. 5.5 Noise A combined booth shall be so designed and constructed that risks resulting from the emission of airborne noise are reduced to the lowest level taking account of technical progress and the availability of means of reducing noise, in particular at source. The following measures can be adopted – where possible:  equipment set on anti-vibration supports;  flexible connections between the ducts and especially between fans and ducts;  choice of fan speed according to the most favourable noise curves; SIST EN 13355:2005+A1:2009

NOTE 3 For noise emitted by air compressors and spraying equipment see EN 1012-1 and EN 1953. 5.6 Radiation Infra-red heating systems shall be designed and constructed to minimise any harmful effect of radiation. The protection can be achieved by the following measures:  interlocking of all doors to shut down the heating system to prevent entry by personnel when the heaters are in use  special barriers or special enclosure of the light tube. Additional warning signs shall be fitted on the outside of the doors (see 7.2.1). 5.7 Safety requirements against dangerous substances 5.7.1 Contact with/or absorption of dangerous fluids (paints, solvents) Contact with or absorption of dangerous substances sprayed shall be reduced by forced ventilation as far as possible (see 5.7.2). See also provisions for the information for use to be included in the instruction handbook in 7.2.2. 5.7.2 Inhalation of aerosols and solvent vapours 5.7.2.1 Forced ventilation In order to avoid inhalation of aerosols and solvent vapours the combined booth shall have an adequate forced ventilation taking into account:  type of application,  size and shape of items,
 amount of dangerous substances sprayed,  exposure limit values relevant to the used coating material (examples given in annex !D"). 5.7.2.2 Airflow The following measures shall be applied: Measures to prevent an atmosphere contaminated by aerosols and solvent vapours of organic liquid coating materials above the exposure limit values.

For residual risks emanating from the hazards dealt with in this clause see 7.2.2. 5.7.2.3 Air velocity Combined booths shall be designed for air velocities specified below for empty booth conditions as described in a), b) and c): a) For combined booths for similar items (e.g.: small vehicles, vans) and combined booths for large similar items (e.g.: buses, trucks):  The average of measured air velocities shall be at least 0,30 m/s,  Single measured values shall be at least 0,25 m/s. Corresponding measurement points are specified in annex B. b) For combined booths for industrial items of various sizes: The air velocity at any point shall not be less than 0,30 m/s. c) For combined booths with a working pit air velocities specified below shall be measured inside the working pit. The average of measured air velocities inside the working pit shall be at least 0,30 m/s. Single measured values inside the working pit shall be at least 0,25 m/s. Corresponding measurement points are specified in annex B. Special air velocities are acceptable for a combined booth where very long items are to be painted (e.g.: train carriages, aeroplane), but the health and safety of the operator shall be ensured. The conditions for the health of the operator inside the combined booth shall be evaluated by special risk assessment. The use of personal breathing protective devices is required when spraying inside enclosures (e.g. train carriages, trucks, busses or in a working pit within the booth, see clause 7.2.2). 5.7.2.4 Monitoring of air velocity Combined booths shall be provided with a device that is capable of monitoring air velocity performance. The ventilation air velocity shall not fall below that specified in 5.7.2.3 (see 5.8.2.5.1.). Failure of the ventilation system, or insufficient ventilation, shall be indicated by a visual and audible alarm (see EN 981). 5.7.3 Inhalation of toxic gases released by the heating device a) General Heating devices using combustible substances shall comply with specific standards EN 746-1, EN 746-2, and EN 525. To avoid reintroduction of contaminated air, the fresh air inlet duct shall be positioned apart from the exhaust air duct and (for indirect systems) the burner flue. SIST EN 13355:2005+A1:2009
