This online Eye Safety in Construction Environments course provides employees with the information they need to recognize and avoid eye hazards that they can encounter on a job site. An estimated 24 million eye injuries occur in the U.S. each year. About 2,000 of them will occur today, and every day thereafter, while people are at work. All too many of them will cause the victim to lose some or all of their eyesight. But eye injuries can be prevented.
