Editing Implosion (mechanical process) (section)

=== Cathode-ray tube and fluorescent lighting implosion ===
A high vacuum exists within all [[cathode-ray tube]]s. If the outer glass envelope is damaged, a dangerous implosion may occur. The implosion may scatter glass pieces at dangerous speeds. While modern CRTs used in televisions and computer displays have epoxy-bonded face-plates or other measures to prevent shattering of the envelope, CRTs removed from equipment must be handled carefully to avoid injury.<ref name='Bali'>{{cite book | last = Bali | first = S.P. | title = Colour Television: Theory and Practice | publisher = Tata McGraw-Hill | date = 1994-06-01 | page = 129 | url = https://books.google.com/books?id=53nnX4fnnNIC&pg=PA129 | isbn = 9780074600245 | url-status = live | archiveurl = https://web.archive.org/web/20170321123205/https://books.google.com/books?id=53nnX4fnnNIC&pg=PA129 | archivedate = 2017-03-21 }}</ref>
