Regulatory,Warning and guide
There are typically nine main categories of hazard warning signs, each represented by specific symbols and colors. These categories include signs for health hazards, physical hazards, environmental hazards, and more. The exact number of distinct hazard warning signs can vary by country and regulatory agency, as different standards may apply. For example, the Globally Harmonized System (GHS) identifies numerous specific hazard symbols, while other systems may have their own variations.
Hieroglyphs can be categorised in many different ways, such as grouping them into animals, birds and parts of their bodies, humans and parts of their bodies, small signs, tall signs, signs depicting plants and so on.In linguistic terms the hieroglyphic signs may be grouped as follows:single consonant signs (such as a hand for d)two consonant signs (such as the basket for nb)three consonant signs (such as the star for dw3)ideograms (such as a standing man with arms raised before him for "praise" or a mouth for "mouth")determinatives (such as the papyrus roll) which have no sound value and only serve to help classify words into their general meaning.There therefore 5 categories of hieroglyphs using this system.

Signs are generally categorized into three main types: icons, indexes, and symbols. Icons resemble what they represent (like a photograph), indexes have a direct connection to their meaning (like smoke indicating fire), and symbols have arbitrary meanings agreed upon by social convention (like words in a language). These categories help in understanding how we interpret various forms of communication in different contexts.
