IT-305 INDUSTRIAL SAFETY OSHA LOG 300
EXERCISES
The student should print several copies of the OSHA Log 300 included on this CD in the file “OSHA forms” or “Studentlog300.xls” and review or print the PDF file “OSHArecordkeepingforms.pdf” also on this CD in the same folder. This PDF file will give you excellent instructions on filling out the OSHA Log 300, however most of the same information is also contained in Appendixes B, C and D beginning on page 476 in the text.
If you are having trouble opening the PDF file from the CD you may use the Internet and go to:
http://www.osha.gov/recordkeeping/index.html
Click on the link for either an
Excel Template or PDF file:
“Open
forms for CY 2002 and CY 2003 - PDF [Adobe Acrobat® (version 3.0 or higher) -
PDF 1.1 MB]”
The student should familiarize himself with the OSHA Log 300 form (page 23). The form is self-explanatory but the columns that you will mostly be concerned with are columns F - M5. There is an Excel Template for the Log 300 included on the CD. This file will allow you type your interpretations to the Log 300 exercises and compute column totals.
WITH RESPECTS TO THE NUMBER OF LOST WORKDAYS DUE TO AN ACCIDENT OR ILLNESS THE OSHA 300 USES CALENDAR DAYS IN LIEU OF WORKDAYS. If, for instance, a worker was injured on Thursday and was not able to return to work on Monday the number of lost-time days is three (3); Friday, Saturday and Sunday.
Please turn to page 25 in the text and read the individual Files in Case Study 2.1 to see how the form is used to record accidents. On page 28 is the completed example and explanations given beginning on page 27. You may notice a typo-involving File #6, the “check” does not belong in column M2.
The student should note the difference between “first aid” and “medical treatment.” This is the distinguishing feature that makes an accident “recordable” or not. If medical treatment is received as described in Appendix B and D the File of the accident is placed on the log and is recordable. If first-aid is received the File is not required to be noted on the log.
The student should be familiar with the definitions of what is Medical Treatment and First-Aid. They will come in handy on the test. The truth is most are very easy to distinguish, however some are border line. For example: What if an employee is playing softball on Saturday for a company sponsored team. The company only purchased the uniforms with their logo and name. If the employee slides into second base and injures his knee that requires surgery. Is it recordable? Well the answer is maybe, but most likely not. The reason is that he is not being paid….. however suppose the employee was a salary exempt employee? Probably does not make a difference… however suppose all the team’s players were employees of the company? Yea its getting closer…. suppose it was on a weekday afternoon instead of a Saturday? Would it make a difference if the game took place on company owned property, say for example, at the company picnic? Yea … now it becomes a recordable incident.
What you see is that there can be some management interruption of the incident and if it is an accident at all. In some cases there is no real ‘clear-cut” right or wrong answer so it is best to be conservative and have a methodology that meets the letter of the law regarding accident reporting.
Calculation of Incidence Rates:
OSHA uses a formula to compute incident rates. This formula is on page 19 in the text. However the best way to remember it is:
Incident Rate = 
In Case Study 2.1 there were 250 employees and the “# of incidents” are the column totals described below. This formula is used for all incident rates; the only thing that changes is what you are trying to measure. Remember “one” incident rate is worthless, the value comes from “trends” over time. However, using this formula OSHA (and an organization’s management) are able to compare incident rates from one plant to another or one company to another regardless of the # of employees.
There is some confusion in the book as to how incident rates are calculated. OSHA changed their reporting requirements beginning in 2004, the year this text was published, and the authors were somewhat confused. Therefore, right or wrong, this is how it will be done.
LWDI (injuries only) will use the totals from columns H and I that are also (√’d) in M1.
Total Injury incident rate will use the total from column M1 minus Deaths.
Total Illness incident rate will use the total from columns M2 - M5.
Fatality incident rate will use the total from column G.
Number-of-lost-workdays rate (injuries and illnesses) will use the total from columns K and L.
Specific-hazard incident rate (for example “eye injuries”) will require the student to review each “File” for eye injuries and compute a total; there is no column specifically dedicated to “eye injuries.”
Please note there is a typo involving the computation of the LWDI (injuries only) in the formula the number 2000,000 is incorrect it should be 200,000 as the other formulas.
Please also note there is a typo involving the computation of the “Number-of-lost-workdays rate.” The text uses the number 26 however if you total columns K and L the total is 36 making the rate 14.1 instead of 10.4.
For additional practice turn to page 44 - 46 in the text and work questions 2.25 – 2.33. The answers to these questions are on the CD in the file “Chapter 2 Answers.doc”.
For test purposes the comprehensive problem will mirror Case Study 2.1, Question 2.29, and Question 2.30. The remaining questions at the end of the chapter will aid the student in comprehending the material.
Here is another Case Study to aid the student comprehend the Log 300.
A metal products fabrication and assemble plant employs 650 workers and has the following injury/illness experience for the year. Workers are employed on a regular 40-hour work-week. Below are descriptions of accidents (files). Complete the OSHA Log 300 for the following accidents and use the results to compute the identified incident rates.

|

Compute the following:
LWDI (injuries only) will use the totals of the √’s from columns H and I that are also (√’d) in M1.
a) LWDI for 650 worker firm.
b) Total Injury incident rate will use the total from column M1 minus Deaths.
c) Total Illness incident rate will use the total from columns M2 - M5.
d) Fatality incident rate will use the total from column G.
e) Number-of-lost-workdays rate (injuries and illnesses) will use the total from columns K and L.
f) Specific-hazard incident rate (for example “exposure to solvent”) will require the student to review each “File” for exposure to solvent and compute a total; there is no column specifically dedicated to “exposure to solvent.”
Answer:
|
File 1, 2 & 3 |
Non-recordable incident only first-aid was received. |
|
File 16 |
Non-recordable incident injury or accident didn’t involve work even through he returned to work with light duty. This is a management decision to accommodate the worker. |
