Safety signs and symbols are important safety communicating tools, they help to indicate various hazards that present in plant site or workplace. At the same time, they warn workers to always keep watching out for those hazards by giving required information and safety instructions.
Safety signs and symbols do not only inform the presence of hazards but also help create workers’ safety awareness. It is very important in reducing accidents in the workplace more obviously in manufacturing, heavy industry and on construction sites but also important in office-based environments as well.
To get the most out of health and safety signs and symbols, you should choose the right ones for each work location on your premises. Each work area needs different workplace health and safety signs and symbols. This is because each work area has different types of hazards. A risk assessment of each activity or the designated area will help identify hazards. Appropriate actions for ensuring safety can then be drawn up and selecting the appropriate safety signs can then be selected. Where possible safety signs showed needs to be changed (at least their location) to keep the safety message fresh and to avoid “sign blindness”.

Safety Signs and Symbols Standards
Safety signs and symbols consist of messages, words and pictorial symbol with a variety of sizes, shapes, and colors. All the shapes and colors are standardized. Each shape has different meaning and each color reflects specific meaning.
Using standardized health and safety signs and symbols will make them understandable and overcome language barriers and the new ISO 7010 standard is the first step towards global harmonization of safety symbols.
