A friendly (or not-so-friendly) reminder from the Occupational Safety and Health Administration: Employers must post OSHA Form 300A between Feb. 1 and April 30.

The summary must include the total number of job-related injuries and illnesses that occurred in 2012 and were logged on OSHA Form 300, also known as "Log of Work-Related Injuries and Illnesses."

"To assist in calculating incidence rates, information about the annual average number of employees and total hours worked during the calendar year is also required," OSHA explained in a news release. "If a company recorded no injuries or illnesses in 2012, the employer must enter 'zero' on the total line."

Form 300A must be signed and certified by a company executive, and displayed in a common area where other employee communications typically are posted, OSHA added.

Copies of OSHA Forms 300 and 300A are available in either Adobe PDF or Microsoft Excel spreadsheet format.
