Logmend / Reference

incident_outcome and type_of_incident codes

Two columns of the case file turn the circles on the Form 300 log into single digits.

Have the log open? Drop it in and get both ITA files with the errors repaired.

incident_outcome (CSV column H)

Code	Form 300	Meaning	Days away (column I)	Days transfer or restriction (column J)
1	(G)	Death	Whole number	Whole number
2	(H)	Days away from work	Must be greater than zero	Zero or more
3	(I)	Job transfer or restricted work activity	Must be zero	Must be greater than zero. 0 or blank is not accepted.
4	(J)	Other recordable cases	Whole number	Whole number

Pick the most serious outcome. A case with three days away and ten days of restricted duty is a 2, with 3 in column I and 10 in column J.

OSHA's sample CSV includes a row with outcome 3 and zero in both day columns. OSHA's FAQ says zeros and blanks in djtr_num_tr are not accepted for outcome 3. The converter follows the FAQ and stops on that row.

Day counts may be capped at 180 calendar days under 29 CFR 1904.7(b)(3)(vii). The CSV columns hold up to 3 digits.

type_of_incident (CSV column K)

Code	Form 300	Meaning
1	(M)(1)	Injury
2	(M)(2)	Skin disorder
3	(M)(3)	Respiratory condition
4	(M)(4)	Poisoning
5	(M)(5)	Hearing loss
6	(M)(6)	All other illnesses

Short answers

What is incident_outcome 3 in the OSHA 300/301 CSV?

Job transfer or restricted work activity, column (I) of the Form 300 log. It needs more than zero days in djtr_num_tr and zero in dafw_num_away.

Can djtr_num_tr be zero?

For outcome 2, yes. For outcome 3, no: OSHA says blanks and zeros are not accepted.
