When you consider the time you spend at work each day, you can understand why injuries on the job are a common occurrence.

Of course, the seriousness of these injuries can vary depending on your occupation and responsibilities. But the important thing to remember is the risk of injury is always around you and, in some cases, in places you might not expect.

According to the Bureau of Labor Statistics, more than half of the 3.7 million private industry injury and illnesses cases reported in 2008 involved days away from work, a job transfer or restriction. The injury and illness incidence rate was highest among mid-size private industry establishments (between 50 and 249 workers) and lowest among small establishments (fewer than 11 workers).

BLS reports sprains and strains – often involving the back – represent the most common workplace injuries in the private sector. Occupations with the greatest at risk of these injuries include laborers and material movers; heavy and tractor-trailer truck drivers; and nursing aides, orderlies and attendants. Trip and falls, falls from roofs and other heights, and crush injuries are also common in these occupations.

Even low-intensity jobs, especially ones with lots of repetitive action, can lead to injuries such as carpel tunnel syndrome, electric shock, tendonitis, hearing loss and ulcers. In addition, possible illnesses include

• Asthma and shortness of breath caused by lung disease from breathing in fumes, dusts, smoke and chemicals;

• Various cancers from different chemicals, including lung, stomach, colon and throat cancer from exposure to asbestos and diesel fumes;

• Liver and brain cancer along with angiosarcoma from exposure to vinyl chloride;

• Leukemia as well as blood and bladder cancer from benzene and gasoline; and

• MRSA and staph infections from working in an ambulance, nursing home or hospital.

Most on-the-job injuries are covered by workers' compensation, even if you're at fault.

In order for you to protect your rights and receive workers' compensation, you must file a claim during a timeframe determined by your state's Workers' Compensation Board (a two-year deadline is common). A basic accident report from your employer is not enough.

Although your employer should have the forms you need to file your claim, you can also contact your state or local workers' compensation office to request them.

You may also want to seek the assistance of a lawyer experienced in workers' compensation law. A lawyer gives you access to expert advice and insider knowledge that's helpful when difficulties arise. Furthermore, you can get these benefits without any out-of-pocket costs.
