Long Term Impact

AbstractIn 2014, a fire at the Hazelwood open cut coal mine (Victoria, Australia) burned for about 6 weeks. Residents of the adjacent town of Morwell were exposed to high levels of fine particulate matter (PM2.5) during this period. Three and a half years after the event, this study aimed to investigate the long-term impact of short-term exposure to coal mine fire smoke on asthma.A cross-sectional analysis was undertaken on a group of exposed participants with asthma from Morwell (n=165) and a group of unexposed participants with asthma from the control town of Sale (n=64). Town exposure status was determined by modelled PM2.5data for the mine fire period. Respiratory symptoms were assessed with a validated respiratory health questionnaire and symptom severity score. Asthma control was assessed with an asthma control questionnaire. Lung function testing included spirometry, bronchodilator response, and fraction of exhaled nitric oxide.There was no evidence that exposed Morwell participants had more severe asthma symptoms, worse lung function, or more eosinophilic airway inflammation compared to unexposed Sale participants. However there was some evidence that Morwell participants had more uncontrolled than well-controlled asthma, compared to the participants from Sale (adjusted relative risk ratio 2.71 95%CI: 1.02, 7.21, p=0.046).Three and a half years after exposure, coal mine fire smoke does not appear to be associated with more severe asthma symptoms or worse lung function, but may be associated with poorer asthma control.Summary take home messageIn people with asthma, short-term coal mine fire smoke exposure does not appear to have long-term impact on severity of asthma symptoms, lung function or eosinophilic airway inflammation, but may affect asthma control.

Coal Mine Fire

Introduction:Despite the influential Hyogo and Sendai Frameworks, risk remains poorly understood in the emergency preparedness sector. Hazard assessment and risk management are usually considered before events. An alternative view considers risk as a cascade of potential consequences throughout an event. The 2014 fire in the Victorian rural community of Morwell included a three-phased event: a small bush fire, from which embers ignited a persistent fire in a disused open cut brown coal mine fire. The consequent air pollution precipitated a public health emergency in the nearby community of 15,000 people.Aim:To examine this event as a case study to investigate concordance with accepted definitions and key elements of a cascading event.Methods:Selected literature informed a risk cascade definition and model as a framework to examine the key post-event public inquiries available in the public domain.Results:Informed by a Conceptual Framework for a Hazard Evolving into a Disaster (Birnbaum et al., 2015), Wong and colleagues promote a Core Structure of a Comprehensive Framework for Disaster Evaluation Typologies (Wong, 2017). This Core Structure provided an adequate model to examine the sequence of events in the Morwell event. Definitions of cascading effects is more complex (Zuccaro et al., 2018). Our analysis of the Morwell event used the authoritative definition of cascading disasters published by Pescaroli and Alexander (2015). Using this definition, the Morwell event increased in progression over time and generated unexpected secondary events of strong impact. The secondary events could be distinguished from the original source of disaster, and demonstrated failures of physical structures as well as inadequacy of disaster mitigation strategies, while highlighting unresolved vulnerabilities in human society.Discussion:The Morwell coal mine fire of 2014 reflects the key criteria of a cascading disaster and provides understandings to mitigate the consequences of similar events in the future.

The Impact

PurposeThe purpose of this paper is to examine the perspectives of local residents regarding the impact of the long-duration Hazelwood open cut coal mine fire in rural Australia.Design/methodology/approachA qualitative approach was undertaken involving 27 in-depth interviews with adults who lived in the town of Morwell, immediately adjacent to the coal mine fire.FindingsParticipant concerns focussed upon fear and confusion during the event, the perceived health effects of the smoke, anger towards authorities and loss of a sense of community and sense of security. One of the significant ways in which people managed these responses was to normalise the event. The long duration of the event created deep uncertainty which exaggerated the impact of the fire.Research limitations/implicationsUnderstanding the particular nature of the impact of this event may assist the authors to better understand the ongoing human impact of long-duration disasters in the future.Practical implicationsIt is important to provide clear and understandable quality information to residents during and after such disasters.Originality/valueWhile there is an extensive literature exploring the direct social and psychological impacts of acute natural disasters, less qualitative research has been conducted into the experiences of longer term critical events.

Respiratory Outcomes

In 2014, wildfires ignited a fire in the Morwell open cut coal mine, Australia, which burned for six weeks. This study examined associations between self-reported respiratory outcomes in adults and mine fire-related PM2.5 smoke exposure. Self-reported data were collected as part of the Hazelwood Health Study Adult Survey. Eligible participants were adult residents of Morwell. Mine fire-related PM2.5 concentrations were provided by the Commonwealth Scientific and Industrial Research Organisation Oceans & Atmosphere Flagship. Personalised mean 24-h and peak 12-h mine fire-related PM2.5 exposures were estimated for each participant. Data were analysed by multivariate logistic regression. There was some evidence of an association between respiratory outcomes and mine fire PM2.5 exposure. Chronic cough was associated with an odds ratio (OR) of 1.13 (95% confidence interval 1.03 to 1.23) per 10 μg/m3 increment in mean PM2.5 and 1.07 (1.02 to 1.12) per 100 μg/m3 increment in peak PM2.5. Current wheeze was associated with peak PM2.5, OR = 1.06 (1.02 to 1.11) and chronic phlegm with mean PM2.5 OR = 1.10 (1.00 to 1.20). Coal mine PM2.5 smoke exposure was associated with increased odds of experiencing cough, phlegm and wheeze. Males, participants 18–64 years, and those residing in homes constructed from non-brick/concrete materials or homes with tin/metal roofs had higher estimated ORs. These findings contribute to the formation of public health policy responses.
