Strictly speaking, heat radiation ranges from infrared to visible light (VIS) up to ultraviolet (UV) — depending on the temperature. IR radiation cannot be perceived by the human eye. It extends over the electromagnetic spectrum from 780 nm to 1 mm (1,000,000 nm). IR radiation is divided into three spectra: • IR A (780nm–1400nm) • IR B (1400nm–3000nm) • IR C (3000nm–1mm) The invisible danger The effect of infrared radiation on human tissue can be harmful. Since it is not immediately noticeable, infrared radiation can increase the risk of permanent eye damage, such as cataracts. Levels of infrared protection and recommendations for use according to EN 171 Level of protection Recommended use in accordance with EN 171 4-1.7 average temperature of the radiation source up to 1090°C* 4-2 average temperature of the radiation source up to 1110°C (forges) 4-3 average temperature of the radiation source 1190°C (glass blowing)* 4-4 average temperature of the radiation source 1290°C (foundries) 4-5 average temperature of the radiation source 1390°C (steel foundries)* 4-6 average temperature of the radiation source 1510°C (iron foundries) Principle: The greater the wavelength, the lower the penetration depth into the tissue. Caution: For applications requiring prolonged or repeated viewing of glowing objects, it is essential that suitable safety eyewear be worn.
