JERSEY CITY -- Dominick V. Daniels, 78, a New Jersey Democrat who was an important influence on labor education bills during an 18-year career in the House of Representatives, died July 17 at Christ Hospital here. The cause of death was not reported.

Mr. Daniels was a senior member of the House Education and Labor Committee, which he joined as a freshman congressman in 1959. He served until 1976, when he retired to practice law.

He headed influential subcommittees that dealt with legislation concerning health and safety in the work place, and postal and federal payrolls.

He helped establish the principle of federal supervision over occupational health and safety in industries around the country; a particular concern for many years was federal legislation regulating summer camps for children. Mr. Daniels also introduced legislation to force schools and colleges to comply with the 1954 Supreme Court decision against racial segregation.

A Union City resident, Mr. Daniels also worked to improve the plight of the handicapped, especially children, and migrant workers, and sought to combat drug addiction and hard-core pornography.

Born in Jersey City of immigrant Italian parents, he graduated from Fordham University and received his law degree from New Jersey Law School. He was admitted to the bar at age 21. He began a successful career in politics in heavily Democratic Hudson County while still a young man. He resigned as presiding magistrate in Jersey City to run for Congress.

Survivors include his wife, Camille, of Union City; two daughters; five sisters; one brother, and four grandchildren.
