Poussières de silice dans les activités de travaux publics
La Fédération des travaux publics de Lorraine et ses partenaires publient un guide proposant des mesures pour prévenir le risque d'exposition aux poussières de silice durant les activités de travaux publics. Sont rappelés dans un premier temps les lieux où l'on peut trouver de la silice, les professions susceptibles d'être exposées, les effets sur la santé et les moyens de se protéger. Les mesures de prévention sont ensuite détaillées pour les activités et situations de travail suivantes...
A universal rig for supporting large hammer drills: Reduced injury risk and improved productivity
Drilling holes into concrete with heavy hammer and rock drills is one of the most physically demanding tasks performed in commercial construction and poses risks for musculoskeletal disorders, noise induced hearing loss, hand arm vibration syndrome and silicosis. The aim of this study was to (1) use a participatory process to develop a rig to support pneumatic rock drills or large electric hammer drills in order to reduce the health risks and (2) evaluate the usability of the rig. Seven prototype rigs for supporting large hammer drills were developed and modified with feedback from commercial contractors...
Hazard identification checklist: Occupational safety and health issues associated with green building
This checklist accompanies the e-fact on the same topic and aims to help identify the potential hazards to workers’ safety and health associated with the planning and construction of green buildings, their maintenance, renovation (retrofitting), demolition, and on-site waste collection. It also gives examples of preventive measures to address these hazards. Some of these OSH hazards are new compared with traditional construction sites and are associated with new green materials, technologies or design. Other hazards are well-known to the construction sector but they arise in new situations...
Occupational safety and health issues associated with green buildings : E-fact 70
This e-fact provides information on the work-related risk factors and the occupational safety and health (OSH) issues associated the planning and construction of green buildings, their maintenance, renovation (retrofitting), demolition, on-site waste collection. Some of these OSH risks are new compared with traditional construction sites and are associated with new green materials, technologies or design. Other risks are well-known to the construction sector but they arise in new situations or combinations associated with green buildings and therefore demand particular consideration. Source : https...
Exposition des travailleurs de la construction à la silice cristalline – Exploitation d’une banque de données tirée de la littérature
Il n'y a pas que dans les mines où les travailleurs peuvent être exposés à la poussière de silice. Plusieurs études ont démontré des niveaux d'exposition élevés dans le secteur de la construction où l'on retrouve plusieurs matériaux contenant de la silice, tels que le béton, le ciment, et le mortier. Les chercheurs veulent donc dresser un portrait détaillé de l'exposition à la silice en exploitant une banque récemment créée dans le cadre d'un projet...
Control of exposure to silica dust : A guide for employees
This leaflet explains what employers and employees should do to prevent lung disease caused by exposure to silica at work. Silica is a natural substance found in most rocks, sand and clay and in products such as bricks and concrete. In the workplace these materials create dust when they are cut, sanded, carved etc. Some of this dust may be fine enough to breathe deeply into the lungs and cause harm to health. The fine dust is called respirable crystalline silica (RCS) and is too fine to see with normal lighting. The leaflet explains how RCS can damage health and what to do to prevent harm. Source...
Allergies professionnelles. Une réalité insidieuse : Dossier Travail et Sécurité
Les allergies professionnelles, souvent considérées par les salariés comme une pathologie inhérente au métier, touchent généralement des personnes jeunes (39 ans en moyenne pour l'asthme et 35 ans pour les dermatoses), qui travaillent souvent dans des PME/TPE. Leur reclassement est difficile et elles sont souvent obligées de changer de métier. La prévention est peu aisée et passe, quand l'activité professionnelle le permet, par la substitution des produits contenant des allergènes, ou par l'automatisation...
Fatalities due to dichloromethane in paint strippers: A continuing problem
Background Exposure to dichloromethane (DCM or methylene chloride - CH2Cl2) in paint strippers continues to be an avoidable source of morbidity and mortality. DCM has been under regulatory scrutiny by occupational and consumer product agencies since the identification of its carcinogenicity in the mid-1980s. Methods We investigated two independent workplace incidents that resulted in three cases of DCM intoxication from paint stripper use. Results Each incident investigated resulted in a fatality. A third worker suffered obtundation requiring hospitalization and intubation. Conclusions The continued...
Dangers of Bathtub Refinishing
At least 14 workers have died since 2000 as a result of using stripping agents containing methylene chloride during bathtub refinishing. Many stripping products (including those that may also be available to consumers) contain high percentages of methylene chloride. Methylene chloride is extremely dangerous when not used properly. Alternative products and processes exist for bathtub refinishing. Products containing methylene chloride should be avoided when possible. Earlier this week NIOSH and OSHA released a joint Hazard Alert titled Methylene Chloride Hazards for Bathtub Refinishers http://www...
New website on site work and silica
The US based Center for Construction Research and Training (CPWR), has launched a 'Work safely with silica' website. CPWR, an organisation working closely with US construction unions, says as well as giving details of US silica regulation and official research, the new resource includes other research, articles, and training materials, as well as responses to frequently asked questions. Central features of the new site include a 'Know the hazard' section, geared for anyone interested in learning more about why silica is hazardous, the risk, who's at risk, the health effects...
