Barrett drowned, at the age of twenty-five, while investigating the sea-bottom of [[Port Royal]] near [[Kingston, Jamaica]], as part of the Jamaican Geological Survey. Geologist Simon F. Mitchell describes:<blockquote>[Barrett] carried back to Jamaica a diving-apparatus to enable him personally to explore the reefs. Having once gone down safely and successfully in shallow water, he would not wait for the assistance of his friends; and set out on the 19th of December, attended by a crew and servants, to the coral-reefs outside Port Royal. At some distance from the land he descended into deep water, provided with 100 feet of air-tubing, and holding the "life-line" only in his hand; and after the lapse of more than half an hour he floated to the surface, but no longer alive.<ref name=":2" /></blockquote>After his death, American mining engineer James G. Sawkins took over Barrett's position as leader of the team.<ref name=":1" />

Barrett was buried at [[Saint Andrew Parish, Jamaica|St. Andrew Parish]] Church.<ref name=":1" />

His posthumous son Arthur Barrett and grandson Lucas Barrett were electrical engineers and ran the firm of Baily, Grundy and Barrett in Cambridge.<ref>{{cite web|title=1922 Who's Who In Engineering: Company B|url=https://www.gracesguide.co.uk/1922_Who's_Who_In_Engineering:_Company_B|work=Grace's Guide to British Industrial History|accessdate=17 May 2019}}</ref>
