If you keep electronic 300 Logs, you may be missing key instructions
When OSHA introduced the 300 Log in 2001, many employers still kept paper records, so OSHA’s packet of PDF forms includes instructions that aren’t in the regulations. Safety professionals who maintain electronic 300 Logs could be missing important information.
Programs that manage electronic 300 Logs will typically include questions to gather information such as the date of the injury and the body part affected. However, OSHA’s packet of forms provides clarification on a number of points.
Delete incidents
If the status of a case changes or the employer learns the incident wasn’t work-related, OSHA explained that employers may “draw a line through the original entry or, if you wish, delete or white-out the original entry.” Employers using electronic records can delete entries that were erroneously added to the 300 Log.
Classifying incidents
Employers classify recordable incidents by the most serious outcome, which in descending order are death, days away, restriction/transfer, and other recordable. The packet explains that employers must “choose only one of these categories.” If the outcome changes, employers must revise the 300 Log.
For example, an injured worker might initially need days of restriction, but later requires surgery and incurs days away. If that happens, the employer would list day counts in both the “days away” and the “restriction/transfer” columns but would reclassify the incident as a days away case.
Employers can stop counting after 180 days, which can be a total from both columns. The instructions explain, “You may stop counting days of restricted work activity or days away from work once the total of either or the combination of both reaches 180 days.” For example, if an employee had 100 days away and 80 days of restriction, the employer can stop counting even if the employee has not yet returned to full duty.
Classifying conditions
Employers must also classify recordable incidents as either injuries or illnesses. Generally, an injury results from a single event (like a cut, fracture, bruise, or burn). In contrast, an illness develops over time, even just a few hours (such as carpel tunnel syndrome, heat stress, or frostbite).
The instructions further explain, “Sprain and strain injuries to muscles, joints, and connective tissues are classified as injuries when they result from a slip, trip, fall or other similar accidents.” Conversely, a strain that develops over time would be an illness. The instructions provide extensive examples of illnesses for each category such as poisoning or “all other illnesses.”
Counting employees and work hours
When preparing the 300A Annual Summary, employers must list the average annual number of employees and the total hours worked by all employees. This information helps determine incident rates. For related information, see our article When determining injury rates, beware of partial years.
Although OSHA provides a calculation to determine average annual employment, that formula is intended for workforces that fluctuate. Employers don’t need to perform the calculation if employee counts remain fairly consistent. The instructions explain:
If you pay about the same number of employees every pay period throughout the year (e.g., about 100), then you can use that number as your annual average employment. If the number of employees fluctuates from pay period to pay period (e.g., your business is seasonal or your establishment grew or shrunk during the year), then you should use the formula below to calculate employment average.
For hours worked, employers must include hours from temps or other contract workers if the employer provided day-to-day supervision (since the employer was responsible for recording injuries to those workers). However, do not count vacation, sick leave, holidays, or other non-work time even if employees were paid for it. Finally, if some employees are not paid by the hour (by the mile, commission, salary, etc.) the employer may estimate the hours worked.
Key to remember: OSHA provides many instructions on how to complete the 300 Log in a PDF packet of the forms, including information that does not appear in the regulations.
