To many people, work is more than just a four-letter word. It's also hazardous to their health.

Not to mention expensive.

The Workplace Health Fund, a voluntary health agency specializing in occupational disease research and education, will hold a seminar tomorrow, from 4 to 6 p.m., on "Health Care Cost Containment."

This is the second in a series of seminars focusing on health issues in the workplace.

"We want to educate workers and their families about the hazards and risks of occupational illness and injury and show them ways to control their own health in the workplace," said Jerry Kaiser, program coordinator at the Health Fund.

The seminar will address strategies to control health care costs such as seeking second opinions on surgery and evaluating the consequences of cigarette smoking. "It is important to take a look at oneself and see what one can do to postpone disease," Kaiser said.

Over 1 million workers are disabled from occupational disease, according to Department of Labor estimates. "As we move into a high-tech world with many new substances introduced into the environment, the health effects will not be adequately measured prior to people becoming exposed to them," said Kaiser.

Other seminars in the series will cover asbestos removal, alcohol and drug abuse, promoting health in the workplace, occupational stress and video display terminals and health. Tomorrow's seminar takes place at the International Union of Operating Engineers, 1125 17th St. NW. It is free. For more information call: 842-7832.
