Hazard & Warning Signs & Labels | RS Components

Hazard warning signs and labels are used to warn workers and the public about hazardous materials, environments and loions. Similarly to other kinds of safety and security signs, the hazard warning signs and labels ensure that they are aware of the danger. Hazard signs and labels are normally yellow with black text and images highlighting the hazard.

Any polyatomic gas molecule exhibits vibration modes, which are excited by infrared radiation. This absorption of radiation by tracer gas molecules is used as a measure of the nuer of, or concentration of tracer gas molecules in the path between an infrared source and detector. This technique is referred to as "absorption spectroscopy".
