Formaldehyde can also be released in everyday products such as chipboard, furniture and paints. Despite its widespread use, formaldehyde is one of the most harmful substances &#8211; even in low concentrations.  <\/p>\n\n\n\n<div class=\"wp-block-bl-block-spacer\"><div class=\"is-style-medium\"><\/div><\/div>\n\n\n\n<h5 class=\"wp-block-heading\">Toxic and carcinogenic &#8211; danger even at the lowest formaldehyde concentrations<\/h5>\n\n\n\n<div class=\"wp-block-bl-block-spacer\"><div class=\"is-style-small\"><\/div><\/div>\n\n\n\n<p>Formaldehyde irritates the eyes, skin and respiratory tract and can cause symptoms such as headaches, nausea and inflammation of the mucous membranes. Chronic or repeated exposure increases the risk of respiratory diseases and cancer. The International Agency for Research on Cancer (IARC) classifies formaldehyde as &#8220;carcinogenic to humans&#8221; (Group 1).  <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Important limit values:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Irritation occurs from as little as 0.1 ppm<\/li>\n\n\n\n<li>The occupational exposure limit value (OEL) is only 0.3 ppm<\/li>\n\n\n\n<li>In sensitive areas such as schools, laboratories or medical technology, even lower guide values often apply<\/li>\n<\/ul>\n\n\n\n<div class=\"wp-block-bl-block-spacer\"><div class=\"is-style-small\"><\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Explosion hazard &#8211; Highly flammable and explosive mixtures<\/h2>\n\n\n\n<div class=\"wp-block-bl-block-spacer\"><div class=\"is-style-small\"><\/div><\/div>\n\n\n\n<p>Formaldehyde is highly flammable and forms explosive mixtures with air in higher concentrations. These can easily ignite when exposed to ignition sources such as sparks or heat. The ignition limit is between approx. 7 and 73% by volume, the flash point is -19 \u00b0C. There is therefore a risk of explosion, particularly in poorly ventilated rooms or in the event of leaks.<\/p>\n\n\n\n<div class=\"wp-block-bl-block-spacer\"><div class=\"is-style-small\"><\/div><\/div>\n\n\n\n<h5 class=\"wp-block-heading\">Gas detectors for formaldehyde &#8211; Reliable protection against invisible danger<\/h5>\n\n\n\n<div class=\"wp-block-bl-block-spacer\"><div class=\"is-style-small\"><\/div><\/div>\n\n\n\n<p>As formaldehyde is colorless and odorless, gas detectors are essential for the early detection of dangerous concentrations.
