Ua hoʻokumu ʻia ʻo Underwriters Laboratories Inc. ma 1894 e William Henry Merrill. I ka hoʻomaka ʻana o kāna ʻoihana he ʻenekini uila ma Bosetona, ua hoʻouna ʻia kahi Merrill he 25 ona makahiki e nānā i ka World Fair's Palace of Electric. I ka ʻike ʻana i ka hiki ke ulu i kāna kahua, ua noho ʻo Merrill i Kikako e loaʻa nā Laboratory Underwriters.

Ma hope koke iho ʻo Merrill i ka hana e hoʻomohala ai i nā kūlana, hoʻopaʻa i nā hōʻike, hoʻolālā i nā mea hana a me ka wehe ʻana i nā pōʻino Ma waho aʻe o kāna hana ma UL, lawelawe ʻo Merrill i ke kākau ʻōlelo waihona kālā o ka National Fire Protection Association (1903–1909) a me pelekikena (1910-1912) a he lālā ikaika loa ia no ka Papa Ola a me ke Komite Hui ʻAmelika. I ka makahiki 1916, ua lilo ʻo Merrill i pelekikena mua loa o UL.

UL i nā mea maʻamau, "Tin Clad Fire Doors", i ka makahiki 1903. I ka makahiki aʻe, ua hana ka UL Mark i ka hoʻomaka ʻana me ke kāpili ʻana i ke ahi. I ka makahiki 1905, ua hoʻokū ʻo UL i kahi Label lawelawe no kekahi mau huahana huahana e koi pinepine nā hōʻike. Ua nānā nā mea nānā UL i nā loiloi mua o ka hale kūʻai i nā huahana i hoʻopaʻa ʻia i nā ʻoihana hana.

Ua hoʻonui ʻo UL i kahi hui me 64 Laboratories, hoʻāʻo a me nā pono hōʻoia e lawelawe ana i nā mea kūʻai aku ma 104 mau ʻāina. Ua ulu aʻe mai kona aʻa i ka palekana uila a me ke ahi e hoʻoponopono i nā pilikia palekana ākea, e like me nā mea weliweli, ka maikaʻi o ka wai, ka palekana o ka meaʻai, ka hoʻāʻo ʻana i ka hana, ka palekana a me ka mālama ʻana i ka ʻike a me ka hoʻomau o ka nohona.
