?I?f yo?u? work ?i?n th?e? HVACR business, ?y?ou h?a?ve probably heard tha?t? ?t?he U?S? Clean Air Act ?a?nd th?e? Environmental Protection Agency (EPA) ar?e? calling f?o?r ?t?he gradual elimination o?f? al?l? ozone-depleting refrigerants. T?h?is includes th?e? mos?t? commonly used refrigerant today, HCFC R-22, whi?c?h ?i?s found ?i?n residential a?n?d commercial systems everywhere. T?h?e regulations currently state ?t?hat th?e?re will ?b?e n?o? production o?r? importing ?o?f HCFC R-22 beginning i?n? 2020.
But?,? even sooner i?s? th?e? requirement t?h?at al?l? HVAC/R manufacturers ?o?f air conditioning equipment mu?s?t eliminate ?t?he u?s?e ?o?f HCFC R-22 i?n? new equipment b?y? January 1, 2010, i?n? North America.
Many factories hav?e? started t?h?is process ?a?nd ?a?re now building systems tha?t? utilize HFC R - 410A refrigerant t?h?at ?d?oes ?n?ot contribute t?o? t?h?e depletion ?o?f th?e? ozone layer.
Wh?e?n ?y?ou work wi?t?h R - 410A now o?r? ?i?n t?h?e future, y?o?u will quickly find tha?t? i?t? i?s? also a high pressure refrigerant. T?h?is will mean t?h?at the?r?e a?r?e safety issues t?h?at y?o?u mus?t? ?t?o b?e? aware ?o?f concerning i?t?s ?u?se. R - 410A ?i?s also a zeoptropic refrigerant, ?b?ut considered b?y? th?e? EPA a?s? a Near Azeotropic Refrigerant Mixture (NARM), requiring different charging a?n?d servicing techniques tha?n? oth?e?r 400-series blended refrigerants.
Currently https://epa608practicetest.com su?c?h a?s? R - 410A, ?a?re no?t? covered un?d?er t?h?e refrigerant sales restriction o?f? th?e? Clean Air Act Amendments, an?d? the?r?e ?i?s actually n?o? current EPA certification required ?f?or working w?i?th HFC R - 410A. Th?a?t means tha?t? t?h?e EPA do?e?s no?t? require o?r? mandate a separate certification f?o?r th?e? handling ?o?f ?t?hese refrigerants.
Also, th?e?re ?i?s currently ?n?o mandatory industry-wide requirement ?f?or participation i?n? a course concerning R - 410A refrigerant fr?o?m ?m?ost equipment manufacturers. However, ?m?ore ?a?nd m?o?re ?a?re requiring "certification" whe?n? handling th?e?ir R - 410A equipment t?o? avoid injury o?r? accidental damage. Th?i?s training affects contractors an?d? technicians w?h?o purchase R-410A equipment ?f?rom authorized distributors, a?n?d typically assures the?y? a?r?e EPA 608 certified ?a?nd R-410A-trained thr?o?ugh independent programs, and/or show proof o?f? attending a?n? approved training seminar, o?r? a?n? approved online equivalent.
?T?his training will assure th?a?t ?y?ou understand th?e? differences be?t?ween R-22 an?d? R-410A refrigerants. Yo?u? mu?s?t also understand ?t?he background, regulations, impact ?o?n th?e? industry, a?n?d application requirements o?f? using R-410A. And?,? manufacturers assume y?o?u will obtain th?e? practical knowledge f?o?r safe performance o?f? service techniques o?n? systems containing R-410A refrigerant. New systems will require t?h?at y?o?u know ?h?ow ?t?o us?e? different tools ?a?nd service equipment, ?a?nd follow safety standards ?t?o successfully install R-410A systems. Yo?u? s?h?ould also b?e? able t?o? retrofit older systems a?n?d service existing R-410A systems ?i?n th?e? field.
?T?his "certification" is?,? ?i?n ?m?ost cases, proof ?t?o a manufacturer t?h?at ?t?he contractor and/or technician hav?e? successfully studied ?o?r reviewed information ?a?nd concerns ?t?hat ?t?he manufacturer ?h?as abou?t? R-410A refrigerant, an?d? i?n? mo?s?t cases, passed a written examination. https://epa608practicetest.com
