When choosing a warning signal there are many things that need to be considered for selecting the correct warning signal for the intended environment. Firstly, you need to start by looking at the location of the intended warning signal and consider:
– The IP rating needed by the signal enclosure.
– The ambient temperature of the area.
– The available electrical supply in the area.
– The noise level if selecting a sounder.
– The existing light in the area if selecting a beacon – note, it needs to be brighter than the lights already in place.
– Potential explosion area.
Bearing these points in mind, you now need to consider the application fully that the warning signal is to be used on. Below are examples of the top three application/areas warning signals are most commonly used:
Industrial/Marine Applications
For example, loading bays, warehouses, factory floor and marine ports/docks.
Since industrial and marine environments can be hazardous, it’s important to consider a product that can withstand harsh weather conditions, shock and vibration.
Within an industrial factory, they also need to be bright and loud enough to be seen/heard over the machinery that may be in place.
Fire Warning Applications
For example, fitted to ceilings, doors to alert fire exits and assembly points. Fire warning signs may also point to the location of fire-fighting equipment.
These warning signals are usually installed in commercial buildings and other establishments that require added public safety measures, such as hospitals and schools.
Automotive Applications
For example, slow moving vehicles, forklift trucks and emergency vehicles.
Automotive applications generally use amber, flashing warning signals as you may have seen on a wide range of vehicles from tractors to airport baggage vehicles however there are some instances when this needs to be changed for example emergency vehicles require a coloured flashing light, mostly blue or red.
