Maritime pilotage is an important guarantee for the safety of water traffic in port. The pilot is affected by the complex port environment, the differences of crew and equipment of different ships, the physical and psychological pressure of the pilot himself, as well as the management factors from the pilot station and maritime safety administration. In order to avoid pilotage accidents (PAs), it is necessary to study the coupling effect of human-organizational factors (HOFs) on PAs. In this paper, from the perspective of HOF risk coupling in pilotage, the problem of HOF risk coupling in maritime pilotage is studied by using the hierarchical classification idea of the human factors analysis and classification system (HFACS) and the method of system dynamics (SD). First of all, HFACS is used to analyse the HOF risk causal elements (RCEs) in pilotage, and 70 RCEs are summed up in four layers; secondly, the SD coupling model of RCEs is constructed; finally, based on a dataset of PAs collected by the Shanghai Harbour Pilot Association, the coupling simulation of RCEs in pilotage is carried out, and the volatility is evaluated. In general, the safety situation of maritime pilotage has been improving in the Shanghai port. However, four RCEs (negligence, habit, pilotage experience, and violations) in unsafe acts and two RCEs (teamwork and personal safety awareness) in precondition for unsafe acts contribute the most to maritime PAs and need to be paid attention to.

Abstract. The Human Factors Analysis and Classification System (HFACS) methodology was applied to accident reports from three African countries: Kenya, Nigeria, and South Africa. In all, 55 of 72 finalized reports for accidents occurring between 2000 and 2014 were analyzed. In most of the accidents, one or more human factors contributed to the accident. Skill-based errors (56.4%), the physical environment (36.4%), and violations (20%) were the most common causal factors in the accidents. Decision errors comprised 18.2%, while perceptual errors and crew resource management accounted for 10.9%. The results were consistent with previous industry observations: Over 70% of aviation accidents have human factor causes. Adverse weather was seen to be a common secondary casual factor. Changes in flight training and risk management methods may alleviate the high number of accidents in Africa.

On December 14, 1799, 3 prominent physicians—Craik, Brown, and Dick—gathered to examine America’s first president, George Washington. He was complaining of severe throat symptoms and was being treated with bloodletting, blistering, and enemas. Dick advised performing an immediate tracheotomy to secure the airway. Both Craik and Brown were not keen on trying tracheotomy and overruled that proposal. Washington was not involved in making that decision. He most likely had acute epiglottitis that proved to be fatal at the end. If Dick had prevailed, a tracheotomy could have saved Washington’s life. Human factors analysis of these events shows that his physicians were totally fixated on repeating futile treatments and could not comprehend the need for a radical alternative, like tracheotomy. That was aggravated by an impaired situational awareness and significant resistance to change. Leadership model was also based on hierarchy instead of competency, which might have also contributed to Washington’s death.

With numerous efforts undertaken by both industry and academia to develop and implement autonomous merchant vessels, their safety remains an utmost priority. One of the modes of their operation which is expected to be used is a remote control. Therein, some, if not all, decisions will be made remotely by human operators and executed locally by a vessel control system. This arrangement incorporates a possibility of a human factor occurrence. To this end, a variety of factors are known in the literature along with a complex network of mutual relationships between them. In order to study their potential influence on the safety of remotely-controlled merchant vessels, an expert study has been conducted using the Human Factors Analysis and Classification System-Maritime Accidents (HFACS–MA) framework. The results indicate that the most relevant for the safety of this prospective system is to ensure that known problems are properly and timely rectified and that remote operators maintain their psycho- and physiological conditions. The experts elicited have also assigned higher significance to the causal factors of active failures than latent failures, thus indicating a general belief that operators’ actions represent the final and the most important barrier against accident occurrence.

AbstractThe safety of personnel and resources is considered to be a cornerstone of prehospital Emergency Medical Services (EMS) operations and practice. However, barriers exist that limit the comprehensive reporting of EMS safety data. To overcome these barriers, many high risk industries utilize a technique called Human Factors Analysis (HFA) as a means of error reduction. The goal of this approach is to analyze processes for the purposes of making an environment safer for patients and providers. This report describes an application of this approach to safety incident analysis following a situation during which a paramedic ambulance crew was exposed to high levels of carbon monoxide.Levy MJ, Seaman KG, Levy JL. A human factors analysis of an EMS crew's exposure to carbon monoxide. Prehosp Disaster Med. 2012;27(3):1-2.
