Cal/OSHA investigated the college's health and safety procedures from May through November. They found that the college improperly documented the training of employees on how to use industrial vacuum cleaners and computers as well as how to lift heavy objects.
The college, which was fined $1,780, must address the violations by Dec. 17.
Pomona College spokeswoman Cynthia Peters said the college has completed the requests asked of them in the citation.
"The health and safety of our employees and community is always Pomona's No. 1 concern," Peters said.
"When contacted by Cal/OSHA about the investigation, Pomona fully cooperated to ensure that the college provides a safe workplace. "
Four of the violations were for paperwork but "certainly we want to make sure we're compliant," Peters said.
The dining hall workers, with the assistance of Los Angeles union group Unite Here, filed a complaint with Cal/OSHA in April about injury rates on campus.
A Unite Here survey showed that workers at Pomona College, part of the Claremont Colleges consortium, were injured at twice the rate of the national average for cafeteria workers in 2010 and 2011.
Workers, such as Elisea Mendoza, claimed they did not receive adequate training on how to use machinery and were injured.
"I can't wear long sleeves because of the pain," Mendoza said. "I can't carry anything with my left hand."
The Pomona College has had injuries affecting 2 percent or less of its workforce in almost each year since 2006. In 2011 it was about 4 percent, Peters said.
The dining hall workers have been at odds with Pomona College for more than a year and have sought the help of Unite Here in efforts to unionize. College officials and the dining hall workers have not been able to come to an agreement regarding unionization.
College officials on Dec. 1, 2011 fired 17 dining hall workers after they could not provide proof of legal eligibility to work in the United States. The action followed the college receiving complaints that it was not checking the eligibility of workers.
A protest the next day led to 15 people being arrested at Pomona College. The protest was put together by unions such as Unite Here and Claremont College students. Supporters also included the American Civil Liberties Union and the Mexican American Legal Defense and Educational Fund.
Cal/OSHA enforces the state's occupational and public safety laws.
