Cured-in-Place-Pipe (CIPP): Inhalation and Dermal Exposure Risks Associated with Sanitary Sewer, Storm Sewer, and Drinking Water Pipe Repairs
Cured-in-place-pipe (CIPP) is the most popular water pipe repair method used in the U.S. for sanitary sewer, storm sewer, and is increasingly being used for drinking water pipe repairs. Today, approximately 50% of all damaged pipes are being repaired using CIPP technology. The CIPP procedure involves the chemical manufacture of a new plastic pipe called a CIPP inside a damaged water pipe. Little is known about CIPP worker exposures and health risks. CIPP manufacturing sites are highly transient, with a single installation location being used from a few hours to a few days. Unlike traditional manufacturing...

Rhinite et asthme en relation avec les activités de soudage et de brasage
Les différents procédés de soudage et techniques connexes ont la particularité de générer des fumées dont la composition et l'intensité d'émission varient selon la technique employée et la nature des métaux travaillés. Si le caractère irritant des fumées de soudage peut en lui-même induire ou aggraver une rhinite ou un asthme, certains de leurs constituants peuvent également être impliqués dans l'apparition de rhinite et d'asthme par l'intermédiaire...
Airborne asbestos exposures associated with the installation and removal of roofing products
Asbestos-containing roofing products were widely used throughout the 20th century, and certain products are still used in limited quantities today. Roofing products are generally considered non-friable and are not expected to release appreciable amounts of airborne asbestos fibers; however, despite the variety of roofing products that have contained asbestos over time, there are no comprehensive analyses of the exposure data associated with these products in the published literature. The objective of this study was to analyze the available data and characterize asbestos exposures associated with...

Australian Work Exposure Study (AWES) - Carcinogen Exposures Construction Industry
A random, population-based sample of 5528 Australian workers participated in the Australian Work Exposure Study (AWES). Workers answered questions about the tasks they completed and the controls used at work. Based on their responses to those questions, the likelihood of exposure to 38 known or suspected carcinogens was estimated. The AWES focused on the most common tasks performed at work. Workers were not asked directly about their exposures to carcinogens and exposure levels were not measured in the workplace. This report describes the responses provided by 459 AWES participants categorised...
Are the Associations of Cardiac Acceleration and Deceleration Capacities With Fine Metal Particulate in Welders Mediated by Inflammation?
Objective: The aim of this study was to investigate whether associations of acceleration capacity (AC) and deceleration capacity (DC) with metal-PM2.5 are mediated by inflammation. Methods: We obtained PM2.5, C-reactive protein, interleukin (IL)-6, 8, and 10, and electrocardiograms to compute AC and DC, from 45 male welders. Mediation analyses were performed using linear mixed models to assess associations between PM2.5 exposure, inflammatory mediator, and AC or DC, controlling for covariates. Results: The proportion of total effect of PM2.5 on AC or DC (indirect effect) mediated through IL-6 on...
Long-Term Metal PM2.5 Exposures Decrease Cardiac Acceleration and Deceleration Capacities in Welders
Objective: The aim of the study was to clarify whether long-term metal particulates affect cardiac acceleration capacity (AC), deceleration capacity (DC), or both. Methods: We calculated chronic exposure index (CEI) for PM2.5 over the work life of 50 boilermakers and obtained their resting AC and DC. Linear regression was used to assess the associations between CEI PM2.5 exposure and each of AC and DC, controlling for age, acute effects of welding exposure, and diurnal variation. Results: Mean (standard deviation) CEI for PM2.5 exposure was 1.6 (2.4)?mg/m3-work years and ranged from 0.001 to 14...

Understanding how to improve the management of exposure to wood dust amongst construction sub-contractors and manufacturing SMEs
Literature review Available evidence was reviewed to develop a better understanding of how to improve the management of wood dust exposure in small and medium-sized construction and manufacturing enterprises (SMEs). There was a paucity of research, with most papers exploring the factors that broadly influence health and safety (H&S) management in SMEs. Factors that influence SMEs' behaviours, included: - i) limited resources (particularly for small construction and wood working companies), - ii) a poor awareness of the importance of ill-health prevention, - iii) risk control advice from...
The Risk of Lung Cancer After Cessation of Asbestos Exposure in Construction Workers Using Pleural Malignant Mesothelioma as a Marker of Exposure
Objective: To study the risk of lung cancer in heavily asbestos-exposed workers after the exposure to asbestos has ended. Methods: Lung cancer was studied in a cohort of 189,896 Swedish construction workers through a linkage with the Swedish Cancer Registry. Asbestos exposure was estimated by the incidence of malignant mesothelioma in the occupational group. Results: There were in total 2835 cases of lung cancer. Workers with heavy exposure to asbestos had an increased risk of lung cancer (relative risks = 1.74; 95% confidence interval, 1.25 to 2.41) before exposure ended and a similar risk to...
