Blue light (pyrotechnic signal)
Blue light is a special kind of light that is really bright and can be seen from faraway places. It's like a superpower for people who work in places where it's hard to see, like at night or in really bad weather.
Blue light comes in little packages called pyrotechnic signals. These packages are kind of like big fireworks that are easy to use. When you light the package, it makes a bright blue light that lasts for a few seconds. This helps people see where you are and what you're doing, even in the dark.
Blue light is different from normal light because it has a different color and wavelength. This makes it easier to see at night or in conditions where normal light might not be very helpful.
Overall, blue light and pyrotechnic signals are important tools for keeping people safe and making sure they can see what's going on in hard-to-see conditions.
