No Open Flames Areas

At workplaces smoking is prohibited in certain areas. These areas are indicated by means of demarcation and notices. In certain instances a demarcated red line on the floor indicates that crossing the line means moving into an area where open flames are prohibited. 

Building and construction contractors often demarcate their entire work area by erecting a fence around it. This ensures that the construction site is demarcated and prevents unauthorized entry onto the site.
