Eine gut durchdachte Beleuchtung auf Baustellen ist essenziell für die Arbeitssicherheit und Produktivität. Unzureichende Lichtverhältnisse erhöhen das Unfallrisiko und erschweren präzises Arbeiten, insbesondere bei Nacht oder schlechten Witterungsbedingungen. Gesetzliche Vorgaben und moderne Technologien helfen dabei, optimale Lichtverhältnisse zu schaffen und Energie effizient zu nutzen.
Anforderungen an die Baustellenbeleuchtung
Die Anforderungen an die Baustellenbeleuchtung sind durch verschiedene Normen und Vorschriften wie die DIN EN 12464-2 und Arbeitsschutzrichtlinien klar geregelt, um sichere Arbeitsbedingungen zu gewährleisten. Besonders wichtig ist die Beleuchtungsstärke, die je nach Einsatzbereich variiert – beispielsweise sind für grobe Arbeiten mindestens 20 Lux erforderlich, während feinere Tätigkeiten bis zu 500 Lux benötigen. Eine blendfreie und gleichmäßige Ausleuchtung ist essenziell, um Schattenbildung und störende Reflexionen zu vermeiden, die die Sicht beeinträchtigen und das Unfallrisiko erhöhen können. Zudem müssen die verwendeten Leuchtmittel witterungsbeständig und robust sein, da sie oft extremen Bedingungen wie Feuchtigkeit, Staub oder Temperaturs
