Show answer and source: OSHA 3148, Guidelines for Preventing Workplace Violence for Healthcare and Social Service Workers (2016), PDF p. 30
Answer: A. Investigate promptly, because a near miss signals hazards that are not adequately controlled
OSHA's guidance says any near miss, a situation that could have caused death, injury or illness, should be promptly investigated. Near misses come from the same conditions as serious outcomes. Skipping it, waiting for a repeat, or deferring to an annual review is not consistent with prompt investigation.
Answer A comes from
OSHA 3148, Guidelines for Preventing Workplace Violence for Healthcare and Social Service Workers (2016), PDF p. 30(opens osha.gov in a new tab)“In addition to investigating all incidents resulting in a fatality, injury or illness, any near miss (a situation that could potentially have resulted in death, injury, or illness) should be promptly investigated as well.”
