Marine Combination Sign: Danger Petroleum Spirit... / No Smoking No Naked Lights
The selection of combination signage is designed to cover many of the other regulations and requirements of all types of signs. It is primarily focused on areas that involve a number of different regulations on one sign rather than having a number of different signs.
Many spaces have recognised hazards and these multi-purpose signs are designed to adequately inform without the need for multiple signs.
They convey a combination of more than one instruction i.e. a hazard and prohibition message or multiple messages requiring different symbols.
