OSHA Form 300A = Summary of Occupational Injuries and Illnesses

The interesting thing about the Summary Form 300a is that even if no work-related injuries or illnesses occur during the year, this form must still be completed! 

 All companies that are required to file the OSHA 300 and OSHA 301 are required to complete the OSHA 300A Summary Form.  Like the other forms, this form DOES NOT have to be submitted, just kept for a required 5 years, in case it IS requested by OSHA.

This is the form, however, that must be posted by February 1 of the year following the year covered by the form.  It is to be kept posted until April 30 of that year.  A good place for it is near the required Labor Law Posters (State or Federal).

To complete this form…

  • Review each entry on the OSHA Form 300 Log of Occupational Injuries and Illnesses to make sure each entry is complete and accurate.
  • Count the number of individual entries of occupational injuries and illnesses made in each category on the Form 300.
    • Write the totals in the corresponding spaces on the OSHA 300a.
    • If no cases are recorded in a category, write “0” in that blank.
  • Calculate the number of employees who worked for your company during the year.
    • Add the total number of employees your company paid in any pay period during the year.  Include all employees, whether they were full-time, part-time, temporary, seasonal, salaried, or hourly.                                                                                            
    • (a)________________  Number of employees paid in any pay period
    • Count how many pay periods your company had during the year.                               Include any pay periods when you had no employees.                                                                                                               
    • (b)_______________ The number of Pay Periods during the year 
    • Divide the total number of employees (a) by the number of pay periods (b).                                              
    • (a)    ________ ÷ (b)­­­­­­­­­­­­­­­­­­ ________  = (c) ________
    • Round the answer to the next highest whole number.  Write the rounded number in the blank marked Annual Average Number of Employees.                                                                                                                                                               
    • (c) rounded =  (d)  ______________________ 
  • Calculate the Total Hours Worked by ALL Employees (OPTIONAL WORKSHEET)
    • Include ALL employees: salaried, hourly, part-time and seasonal workers, as well as any hours worked by other workers subject to day to day supervision by your establishment (like temporary help services workers).
    • Do NOT include vacation, sick leave, holidays, or any other non-work time, even if employees were paid for it. If your company keeps records of only the hours paid or if you have employees who are not paid by the hour, please estimate the hours the employees actually worked.  Here is a simple optional worksheet to calculate total hours worked by your full-time employees in your workplace for the year. 

       __________   Find the number of full-time employees in your workplace for the year.

   X  ___________  Multiply by the number of work hours for one full-time employee in a year.

= (a)___________  This is the number of full-time hours worked.

 +     ___________  Add the number of any overtime hours worked.

  +    ___________  Add the number of hours worked by other employees (part-time, temporary, seasonal)

 = (b)___________ This is the TOTAL number of ALL hours worked.

     (c)___________ ROUND that TOTAL NUMBER to the next highest whole number. 

    •   Write the rounded number in the blank marked Total hours worked by all employees last year.
