ABC is reminding its contractor member firms that their 2017 Occupational Safety and Health Administration (OSHA) Form 300A work-related injury and illness log summaries must be posted in a visible spot on all construction sites ( based on the definition of "establishment" ) Feb. 1 through April 30. The summaries, which list the total number of job-related injuries and illnesses that occurred in 2017 and were logged on the employer's OSHA Form 300A, must be certified by a company executive and displayed on an area where notices to employees are typically posted. Employment information about the average number of employees and total hours worked during the calendar year is also required. Companies with no recorded injuries or illnesses in 2017 must still post the form, with zeros on the total line. Information on electronic submission of the OSHA 2017 Form 300A can be found here .
