These badges provide a <strong>clear visual indication<\/strong> when exposure occurs, changing color from <strong>orange to maroon<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Below, you can see the comparison of a <strong>new badge versus a used badge<\/strong> after exposure\u2014notice the visible color change that makes it simple to recognize when hydrazine is present.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The SafeAir badge can be used for <strong>personnel or area monitoring<\/strong>, with exposure times ranging from <strong>5 minutes up to 2 consecutive days<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Why Hydrazine Monitoring Matters<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Hydrazine<\/strong> is a colorless liquid with a strong, ammonia-like odor. It is highly toxic and extremely destructive to the tissues of the mucous membranes and upper respiratory tract.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Symptoms of exposure may include:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Coughing<\/li>\n\n\n\n<li>Shortness of breath<\/li>\n\n\n\n<li>Wheezing<\/li>\n\n\n\n<li>Laryngitis<\/li>\n\n\n\n<li>Headache<\/li>\n\n\n\n<li>Nausea and vomiting<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Exposure Limits:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>OSHA PEL (Permissible Exposure Limit):<\/strong> 1 ppm (TWA)<\/li>\n\n\n\n<li><strong>NIOSH Ceiling Limit:<\/strong> 0.03 ppm (2-hour ceiling)<\/li>\n\n\n\n<li><strong>NIOSH Guidance:<\/strong> Treat hydrazine as a potential occupational carcinogen<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Hydrazine is most often used as a <strong>rocket and jet fuel<\/strong>, in <strong>pharmaceutical manufacturing<\/strong>, and in <strong>corrosion inhibitors and refining processes<\/strong>. Because of its hazards, accurate monitoring is critical.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Principle of Operation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The Hydrazine SafeAir badge is designed to detect hydrazine <strong>below the permissible exposure limit<\/strong>.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The badge contains a flat indicator layer that reacts with hydrazine, producing a <strong>color-forming reaction<\/strong>.<\/li>\n\n\n\n<li>A <strong>half-triangle shape<\/strong> appears in maroon, signaling exposure.<\/li>\n\n\n\n<li>The color change may appear on <strong>one or both sides<\/strong> of the badge depending on the dose.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This simple visual cue ensures that workers can <strong>quickly recognize and respond<\/strong> to hazardous exposures.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Operating Instructions<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Remove the pouch from refrigeration and allow it to warm to room temperature.<\/li>\n\n\n\n<li>Remove the badge from its protective pouch.<\/li>\n\n\n\n<li>For <strong>personnel monitoring<\/strong>, clip the badge near the breathing zone (collar) with the front side exposed.<\/li>\n\n\n\n<li>For <strong>area monitoring<\/strong>, mount the badge in a central location with the front side exposed.<\/li>\n\n\n\n<li>Watch for the <strong>half-triangle color change<\/strong> beneath the printed exposure dose.<\/li>\n\n\n\n<li>To determine average concentration: divide the exposure dose (ppb-hr) by the exposure time in hours (hr)<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Storage<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For best performance, the <strong>Hydrazine Dual Level SafeAir Badge<\/strong> should be kept refrigerated in its sealed bag until use.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Important Note on Humidity<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">At <strong>relative humidities above 55%<\/strong>, results should be corrected by multiplying by a factor of <strong>1.13 for every additional 10% RH<\/strong> beyond 55%. This ensures accurate concentration readings in humid environments.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>Hydrazine Dual Level SafeAir Badge (382020-50)<\/strong> provides a <strong>simple, cost-effective, and reliable method<\/strong> of detecting hydrazine exposure in both personnel and area monitoring applications. With its <strong>color-changing visual alert<\/strong>, it offers an immediate indication of hazardous conditions\u2014helping keep workers safe in industries where hydrazine is used.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\">You can find this product here: <a href=\"https:\/\/www.gas-sensing.com\/hydrazine-dual-level-safeair-badge-382020-50.html\" data-type=\"link\" data-id=\"https:\/\/www.gas-sensing.com\/hydrazine-dual-level-safeair-badge-382020-50.html\">https:\/\/www.gas-sensing.com\/hydrazine-dual-level-safeair-badge-382020-50.html<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Hydrazine Dual Level SafeAir Badge is a lightweight, easy-to-use chemical detection tool designed to alert workers to the presence of hydrazine.
