1895166 1.0 INTRODUCTION At the request of Japan Canada Oil Sands Limited (JACOS), Golder Associates Ltd. (Golder) conducted a qualitative occupational hygiene exposure assessment (QOHEA) at the Hangingstone Expansion Plant (the Site) located on the JACOS Hangingstone lease, approximately 50 kilometres south of Fort McMurray, Alberta. The objective of the assessment was to characterize potential worker exposure to chemical and physical hazards at the new facility. The assessment was conducted by Dave Ayriss, Certified Industrial Hygienist (CIH) on April 10 and 11, 2018. 2.0 BACKGROUND A comprehensive occupational hygiene (OH) program is the embodiment of the resources, practices and procedures required for the anticipation, identification, assessment and control of chemical, physical and biological agents in the workplace. Key elements of a successful workplace OH program include the following: development of similar exposure groups (SEGs) based on worker locations, job titles/descriptions and estimated contaminant airborne concentrations, relative to applicable occupational exposure limits; grouping of similarly exposed workers based on contaminant exposure, frequency, duration and severity of consequences from exposure; implementation of validated and statistically representative exposure assessment strategies through qualitative and quantitative risk assessment processes; establishment of agent-specific control processes and procedures to address incidents of potential worker overexposure; development of control and protection programs that address and formalize workplace-specific hazards and their control; integration with occupational health, maintenance and engineering programs, and safety management systems; and establishment of adequate human and material resources, including training, to ensure continued program development and implementation. 3.0 SCOPE OF WORK The QOHEA was conducted based on the American Industrial Hygiene Association (AIHA) model for the assessment and management of occupational exposures. Golder’s scope of work for the QOHEA included the following:

  • Risk Assessment Guidance
    Risk Assessment Guidance The assessor can assign values for the hazard severity (a) and likelihood of occurrence (b) (taking into account the frequency and duration of exposure) on a scale of 1 to 5, then multiply them together to give the rating band: Hazard Severity (a) Likelihood of Occurrence (b) 1 – Trivial (eg discomfort, slight bruising, self-help recovery) 1 – Remote (almost never) 2 – Minor (eg small cut, abrasion, basic first aid need) 2 – Unlikely (occurs rarely) 3 – Moderate (eg strain, sprain, incapacitation > 3 days) 3 – Possible (could occur, but uncommon) 4 – Serious (eg fracture, hospitalisation >24 hrs, incapacitation >4 4 – Likely (recurrent but not frequent) weeks) 5 – Very likely (occurs frequently) 5 – Fatal (single or multiple) The risk rating (high, medium or low) indicates the level of response required to be taken when designing the action plan.

  • Management of Occupational Exposure Limits: a Guide for Mine Ventilation Engineers
    Management of Occupational Exposure Limits: A Guide for Mine Ventilation Engineers Derrick J. (Rick) Brake1,2(&) 1 Mine Ventilation Australia, Brisbane, QLD, Australia [email protected] 2 Monash University, Melbourne, VIC, Australia Abstract. Many underground mines do not have a qualified or dedicated occupational (industrial) hygienist on site, or even available as a resource. Many mine ventilation engineers do not even consider occupational exposure moni- toring to be relevant to their role as an engineer. In many cases where occu- pational exposure monitoring is conducted, the mine ventilation engineer is not informed about the results of the monitoring, or if he is, cannot interpret cor- rectly what these results mean. This bunker mentality separating occupational hygiene and ventilation engineering reduces the range of tools available to the ventilation engineer to actively adjust or tune the ventilation system to keep the underground environment healthy, or as healthy as it could otherwise be. This paper sets out the principles and practices that the mine ventilation engineer needs to know to be able to understand how to interpret occupational hygiene monitoring results, and the implications for the mine primary and secondary ventilation systems. Keywords: Occupational Á Industrial Á Hygiene Á Monitoring Underground Á Ventilation 1 Introduction In most countries, occupational (or industrial) hygiene is managed by professional hygienists—quite a different field of specialty to engineers; mine ventilation engineers have only been peripherally involved if at all. The exception is probably South Africa where the role of ventilation engineers now tends to encompass at least basic occu- pational hygiene management. There are arguments for and against combining the roles of hygienist and engineer, but the dual-role system has not been adopted elsewhere to date.

  • Supplementary File 2: Assessment of Quality and Bias
    Supplementary File 2: Assessment of quality and bias In preparing the tool, it was not possible to identify a dominant factor for which studies should be controlled for, instead recognising several key variables. Comparability was therefore scored against a single criterion of ‘effectively controlling for relevant factors’, meaning a maximum of eight points, rather than nine, were available. Where a nested cohort or matched case group was identified within an interventional study, it was agreed that the quality of the study as applied to impact of ETS would be appraised, and not the main interventional study outcomes. This acknowledged that high quality trials not relevant to the impact of ETS exposure could contain poor quality cohorts that were appropriate for inclusion, or vice versa. A point was awarded for satisfactory response on each question, indicated by a tick in the relevant table. Cohort Outcome Measures Domain and outcomes Point Representativeness of the exposed cohort A Truly representative of the paediatric population undergoing surgery B Somewhat representative of the paediatric population undergoing surgery C Selected subgroup of the population undergoing surgery D No description of the cohort selection process Selection of the non-exposed cohort A Drawn from the same community as the exposed cohort B Drawn from a different source C No description of the derivation of the non-exposed cohort Ascertainment of exposure A Secure record (e.g. surgical record, biological test) B Structured interview C Written self-report of self-completed questionnaire D No description Demonstration that outcome of interest was not present at start of the study A Yes B No Comparability of cohorts on the basis of the design or analysis A Study controls for reasonable factors (e.g.
