I work in a chemistry lab, typically, dangerous chemicals are marked with a red, yellow, or orange label. Hazardous is usually marked with an orange label.
Yellow.
red
Satanic Red
On land the danger colours are yellow and black - in the ocean, it is blue coloured patterns that denote danger.
Red colour has large wave length so scattering of red colour is in less amount in the fog day also driver could see sign of danger clearly, for that purpose ...
maybe red because that sometimes shows danger
white is the colour which we can see from the maximum distance and red is a alert signal or danger signal and has good reflections also.
red - symbolising strength, power, danger, war, passion, desire, love etc...
People 1st believed all sign of danger was indicated with blood, it used to mean if someone in an important place was bleeding there was trouble. Now it is used for danger because most danger will cause blood and because of the previous meaning of; "code red"
The reason is because red colour is very catchy than any other colour and catches peoples attention while doing any work
There are a variety of types of laboratories. Some of these include research laboratories, development laboratories, as well as test laboratories.
There are dozens of different laboratory jobs out there, to name a few of the more general ones there would be clinical laboratories, medical laboratories, chemistry laboratories, forensic laboratories, general laboratories and biology laboratories.
