sec.89ADust monitoring and reporting procedure

### sec.89A Dust monitoring and reporting procedure This section applies if the site senior executive for a coal mine becomes aware (the first trigger event ) that the average concentration of respirable dust in the atmosphere of the work environment exceeds the levels stated in section 89 (1) . The site senior executive must ensure— the cause of high average concentration is investigated; and the results of the investigation are recorded and analysed to identify trends and issues with the coal mine’s safety and health management system; and the notification obligations under subsection (4) are complied with; and if any changes to the coal mine’s safety and health management system required under section 89 (3) (b) are made—the changes to the system are recorded; and a further sample is taken within 2 weeks after the first trigger event. If the site senior executive receives the results of the further sample and the results indicate the average concentration of respirable dust in the atmosphere of the work environment exceeds the levels stated in section 89 (1) (the second trigger event ), the site senior executive must ensure— the cause of the continued high average concentration is investigated; and the results of the investigation are recorded and analysed to identify trends and issues with the coal mine’s safety and health management system; and the notification obligations under subsection (4) are complied with; and if any changes to the coal mine’s safety and health management system required under section 89 (3) (b) are made—the changes to the system are recorded. For subsections (2) (c) and (3) (c) , the notification requirements for the first trigger event and second trigger event are— as soon as practicable after the event, coal mine workers in the similar exposure group for the risk created by the high average respirable dust concentration must be told about the high average concentration; and within 24 hours after the event, the following persons must be told about the high average concentration— an inspector; an industry safety and health representative; a site safety and health representative; and within 72 hours after the event, a record of concentrations of respirable dust in the atmosphere of the work environment must be submitted to the chief inspector in a way, and in a format, approved by the chief inspector. In this section— further sample means a sample of the atmosphere of the work environment taken— after the first trigger event for the purpose of determining whether the average concentration of respirable dust in the atmosphere of the work environment continues to exceed the levels stated in section 89 (1) ; and in accordance with AS 2985:2009; and AS 2985:2009 ‘Workplace atmospheres—Method for sampling and gravimetric determination of respirable dust’ as far as practicable, in the same circumstances as the sample of the atmosphere of the work environment that resulted in the first trigger event. The further sample is taken— in an area of the mine similar to the area in which the initial sample was taken; and using— the same coal mine worker used to take the initial sample; or another coal mine worker in the similar exposure group for the risk created by the high average respirable dust concentration. (sec.89A-ssec.1) This section applies if the site senior executive for a coal mine becomes aware (the first trigger event ) that the average concentration of respirable dust in the atmosphere of the work environment exceeds the levels stated in section 89 (1) . (sec.89A-ssec.2) The site senior executive must ensure— the cause of high average concentration is investigated; and the results of the investigation are recorded and analysed to identify trends and issues with the coal mine’s safety and health management system; and the notification obligations under subsection (4) are complied with; and if any changes to the coal mine’s safety and health management system required under section 89 (3) (b) are made—the changes to the system are recorded; and a further sample is taken within 2 weeks after the first trigger event. (sec.89A-ssec.3) If the site senior executive receives the results of the further sample and the results indicate the average concentration of respirable dust in the atmosphere of the work environment exceeds the levels stated in section 89 (1) (the second trigger event ), the site senior executive must ensure— the cause of the continued high average concentration is investigated; and the results of the investigation are recorded and analysed to identify trends and issues with the coal mine’s safety and health management system; and the notification obligations under subsection (4) are complied with; and if any changes to the coal mine’s safety and health management system required under section 89 (3) (b) are made—the changes to the system are recorded. (sec.89A-ssec.4) For subsections (2) (c) and (3) (c) , the notification requirements for the first trigger event and second trigger event are— as soon as practicable after the event, coal mine workers in the similar exposure group for the risk created by the high average respirable dust concentration must be told about the high average concentration; and within 24 hours after the event, the following persons must be told about the high average concentration— an inspector; an industry safety and health representative; a site safety and health representative; and within 72 hours after the event, a record of concentrations of respirable dust in the atmosphere of the work environment must be submitted to the chief inspector in a way, and in a format, approved by the chief inspector. (sec.89A-ssec.5) In this section— further sample means a sample of the atmosphere of the work environment taken— after the first trigger event for the purpose of determining whether the average concentration of respirable dust in the atmosphere of the work environment continues to exceed the levels stated in section 89 (1) ; and in accordance with AS 2985:2009; and AS 2985:2009 ‘Workplace atmospheres—Method for sampling and gravimetric determination of respirable dust’ as far as practicable, in the same circumstances as the sample of the atmosphere of the work environment that resulted in the first trigger event. The further sample is taken— in an area of the mine similar to the area in which the initial sample was taken; and using— the same coal mine worker used to take the initial sample; or another coal mine worker in the similar exposure group for the risk created by the high average respirable dust concentration. - (a) the cause of high average concentration is investigated; and - (b) the results of the investigation are recorded and analysed to identify trends and issues with the coal mine’s safety and health management system; and - (c) the notification obligations under subsection (4) are complied with; and - (d) if any changes to the coal mine’s safety and health management system required under section 89 (3) (b) are made—the changes to the system are recorded; and - (e) a further sample is taken within 2 weeks after the first trigger event. - (a) the cause of the continued high average concentration is investigated; and - (b) the results of the investigation are recorded and analysed to identify trends and issues with the coal mine’s safety and health management system; and - (c) the notification obligations under subsection (4) are complied with; and - (d) if any changes to the coal mine’s safety and health management system required under section 89 (3) (b) are made—the changes to the system are recorded. - (a) as soon as practicable after the event, coal mine workers in the similar exposure group for the risk created by the high average respirable dust concentration must be told about the high average concentration; and - (b) within 24 hours after the event, the following persons must be told about the high average concentration— (i) an inspector; (ii) an industry safety and health representative; (iii) a site safety and health representative; and - (i) an inspector; - (ii) an industry safety and health representative; - (iii) a site safety and health representative; and - (c) within 72 hours after the event, a record of concentrations of respirable dust in the atmosphere of the work environment must be submitted to the chief inspector in a way, and in a format, approved by the chief inspector. - (i) an inspector; - (ii) an industry safety and health representative; - (iii) a site safety and health representative; and - (a) after the first trigger event for the purpose of determining whether the average concentration of respirable dust in the atmosphere of the work environment continues to exceed the levels stated in section 89 (1) ; and - (b) in accordance with AS 2985:2009; and Note— AS 2985:2009 ‘Workplace atmospheres—Method for sampling and gravimetric determination of respirable dust’ - (c) as far as practicable, in the same circumstances as the sample of the atmosphere of the work environment that resulted in the first trigger event. Example— The further sample is taken— 1 in an area of the mine similar to the area in which the initial sample was taken; and 2 using— (a) the same coal mine worker used to take the initial sample; or (b) another coal mine worker in the similar exposure group for the risk created by the high average respirable dust concentration. - 1 in an area of the mine similar to the area in which the initial sample was taken; and - 2 using— (a) the same coal mine worker used to take the initial sample; or (b) another coal mine worker in the similar exposure group for the risk created by the high average respirable dust concentration. - (a) the same coal mine worker used to take the initial sample; or - (b) another coal mine worker in the similar exposure group for the risk created by the high average respirable dust concentration. - 1 in an area of the mine similar to the area in which the initial sample was taken; and - 2 using— (a) the same coal mine worker used to take the initial sample; or (b) another coal mine worker in the similar exposure group for the risk created by the high average respirable dust concentration. - (a) the same coal mine worker used to take the initial sample; or - (b) another coal mine worker in the similar exposure group for the risk created by the high average respirable dust concentration. - (a) the same coal mine worker used to take the initial sample; or - (b) another coal mine worker in the similar exposure group for the risk created by the high average respirable dust concentration.
