Safety signs have been a common sight in many workplaces. In order for signs to be effective, they have to have clear instructions and pictures. The pictures should be easy enough for most people to understand.
There are many factors that determine the effectiveness of a safety sign and how it is implemented. For example, what is the language of the sign? Is it translated to the local language? If the sign can be easily understood, it can be helpful in providing important information to people.
