A survey of exposure constituents and levels to theatrical smokes and fogs, and their impact on respiratory health, among entertainment industry production employees.

This study outlines the results of an industrial hygiene and respiratory health assessment of eight coastal saw mills. It looked at airborne metal concentrations in occupational settings, and also evaluated the respiratory health of saw filing tradesmen. The results of the respiratory health assessment provide evidence that the saw filers studied are at risk for work-related increases in acute respiratory and nasal symptoms as well as for measurable reductions in lung function.

The objective of the generic exposure assessment guidelines is to provide exposure data which can be used in risk assessments by government agencies or the lumber industry itself, and which will address the unique characteristics of the lumber treatment process not found when pesticides are applied in other settings such as agriculture.

Study Purpose: To investigate patterns of extended health benefits (EHB) and long term disability (LTD) utilization for mental disorders among a cohort of health care workers and to investigate differences in rates of utilization over a five-year follow-up period.

This paper explores the pathway from potential hazards in the work environment to the measurement of personal exposure for epidemiologic studies and assesses the influence of gender differences.

The purpose of this study was to conduct a survey of high school students in British Columbia to describe self-reported patterns of work and to calculate work-related injury rates.

Occupational exposures to risk factors for low back disorders have been assessed using job titles, self-assessment, observational methods and direct measures. Direct measures are generally recommended as more precise, but their use is limited in large studies. The purpose of this study was to explore the comparability of two direct measurement methods (electromyography and inclinometry) for continuous low back exposures and the ability to distinguish exposures among workers in different industries.

Work-related back injuries represent 25% of workplace injuries in British Columbia, and more than a quarter of all back strain claims are from employees in five high-risk industries: forestry, wood and paper products, construction, transportation, and warehousing. Epidemiological studies require data on physical exposures to risk factors from large numbers of individuals in order to observe exposure-response relationships and for the results to be representative and generalizable. Unfortunately, there is a tradeoff between precision and expense, with the most precise measurement methods being too expensive to use in large epidemiological studies. The overall goal of this study is to identify a suite of measurements that afford both precision and cost efficiency for large scale work-site studies of numerous physical exposures across diverse settings and occupations.

The report, funded by the Change Foundation in Ontario, identifies several priorities that require further attention to ensure the safety of healthcare workers and how best to implement the necessary changes.

The main objective of this field trial was to compare the concentrations of nitrous oxide found in the nurses' breathing zones when using the new and existing scavenging systems.
