When you look at warning and instructional plates, and even warning signs in and around your workplace, you may notice that these have different headers on them. These headers, which are found at the very top of these metal nameplates and signs, have different meanings, and are not just there to capture your attention. What are the different headers used for these plates and signs, and what does each header mean in terms of your safety and wellbeing? There are actually quite a few headers being used for these nameplates and signs, but the most commonly used ones, and the more important ones are the following: Danger – this is the header that is considered the most serious one of all the headers being used for these nameplates, and this is because of what such a header tells you. When you see a sign or warning and instructional plate that is carrying this red, white and black heading, you should know that extreme caution is needed. This means that the machinery, item or area that you are about it use or enter, comes with hazards that can be fatal. When you see this particular header, you should be aware that the dangers found in the area are not to be taken lightly since these dangers can kill. Warning – this header is used for areas that still present a great deal of danger, and is not to be taken lightly either, although the level of danger present here is lower than the previous header’s. This heading comes in an orange and black color, and is used to inform people of the possibility of very serious injuries and possibly death, if care is not exercised as the warning plate says. Caution – warning and instructional plates that carry this yellow and black heading often tells people of the possibility of minor injuries in the area or with the use of machinery, if people are not careful. While this is lower in level in terms of danger when compared to the previous two headings, this should not be taken lightly either. Even if there is no imminent threat of death when you see a Caution sign or plate, this does not mean that there is no danger involved in the area. Notice – this is considered one of the lighter headings used for signs and nameplates, although nonetheless important. This captures the attention of the reader, and tells them what needs to be done for safe operation of equipment, or for general safety in the area. This is written in blue and white, and is often followed by a rule, a step, or a reminder for what is needed for safety.
