The Occupational Health and Safety Act requires most employers with more than ten employees to record work-related illnesses and injuries using OSHA Form 300A. Partially exempt industries, including low hazard retail, service, finance, insurance, or real estate businesses, are not required to post Form 300A. A list of partially exempt industries can be found here
The required form must be posted from February 1, 2013 until April 30, 2013 and should be displayed in a common area where other notices to employees are typically posted.
Form 300A contains a summary of all job-related injuries and illnesses that occurred in the previous year, as well as the average number of employees and total hours worked during the year. If there were no recorded injuries in 2012, a company should put “0” on the total line. The form must be signed and certified by a company executive.
