A periodic evaluation of the photoluminescent markings should be undertaken to ensure that:
- All products are still configured as at installation and there is no material damage to any of these products.
- All products are clean from general dust build up and any other specific obscuring deposits.
- All products are clearly visible and have not been covered up by floor coverings or other materials.
- All products mark a clear path and have not been obstructed by physical hazards such as machinery, partitions or other equipment.
- All light required to charge the product is operating as designed at installation.
- All products used for emergency systems continue to provide clear escape path marking and there has been no change to the configuration of the building which renders the escape path unusable.
Independent testing of Ecoglo photoluminescent products in accordance with ASTM G155-2004 (7) has determined that there is no material degradation of luminance output due to exposure to weathering by ultra violet light.
The Ecoglo system has also met the following New York City RS6-1A tests for safety and durability:
- 5.0 Flame Spread
- 4.0 Radioactivity
- 3.0 Toxicity
- 2.0 Washability
- 6.0 UV degradation
(7) ASTM G155-2004 Standard Operation Xenon Arc Light Apparatus for Exposure of Non Metallic Materials.
