Ce numéro porte sur la toxicologie en milieu de travail. On y trouve, entre autres : Brûlure à l'acide fluorhydrique Décès reliés à une intoxication par le monoxyde de carbone en milieu de travail Cannabinoïdes synthétiques : le danger d'une exposition accidentelle Pratiques entourant la manipulation des médicaments dangereux dans les établissements de santé du Québec Source :
Safe storage of wood pellet and wood chip fuel
Wood pellets and wood chip biofuel can produce dangerous (toxic) atmospheres in unventilated, enclosed spaces producing carbon monoxide and carbon dioxide, and depleting oxygen concentrations. Appropriate controls to control the potential risk are ventilation and restriction of access to unauthorised persons. The stores and their adjacent areas should be assessed to determine if they should be classed as confined spaces. Training and safe working procedures are required. An HSE Safety Notice has increased awareness of the hazard, particularly amongst operators of small wood pellet or wood chip...
Preventing exposure to carbon monoxide from use of solid fuel appliances in commercial kitchens
This new catering information sheet is published in collaboration with the Heating Equipment Testing and Approval Scheme, the Solid Fuel Association and the Hospitality Industry Liaison Forum. The guidance is aimed specifically at employers who use solid fuel appliances such as tandoori ovens, charcoal grills and wood-fired pizza ovens in commercial kitchens. It is concerned with the risks of exposure to carbon monoxide gas for workers as well as members of the public and outlines how they can be protected and what the law says. Source:
The concentration of carbon monoxide in the breathing areas of workers during logging operations at the motor-manual level
OBJECTIVES: This article compares 2 variants of logging technologies at the motor-manual level: variant A - cutting and delimbing by means of a petrol chainsaw, skidding with the use of a cable winch mounted on a tractor (67-74 kW); variant B - cutting by means of a petrol chainsaw, skidding, debranching and cutting to length by means of a processor aggregated with a farm tractor (61 kW). MATERIAL AND METHODS: Direct dosimetry and non-parametric (moving block bootstrap) methods were used in order to specify the characteristics of the collected sets. RESULTS: Bootstrap average values show that the...
Occupational carbon monoxide fatalities in the US from unintentional non-fire related exposures, 1992-2008
OBJECTIVE: To analyze characteristics of, and trends in, work-related carbon monoxide (CO) fatalities in the US. METHODS : Records of unintentional, non-fire related fatalities from CO exposure were extracted from the Bureau of Labor Statistics' Census of Fatal Occupational Injuries and the Occupational Safety and Health Administration's Integrated Management Information System for years 1992-2008 and analyzed separately. RESULTS: The average number of annual CO fatalities was 22 (standard deviation = 8). Fatality rates were highest among workers aged ≥65, males, Hispanics...
Practice recommendations in the diagnosis, management and prevention of carbon monoxide poisoning
Carbon monoxide (CO) poisoning is common in modern society, resulting in significant morbidity and mortality in the United States annually. Over the past two decades, sufficient information has been published about carbon monoxide poisoning in the medical literature to draw firm conclusions about many aspects of the pathophysiology, diagnosis and clinical management of the syndrome, along with evidence-based recommendations for optimal clinical practice. This article provides clinical practice guidance to the pulmonary and critical care community with regard to the diagnosis, management and prevention...
Risk of carbon monoxide release during the storage of wood pellets
The HSE is issuing this notice to those who use, install, maintain or distribute wood pellet boilers or manufacture/store/distribute wood pellets. Since 2002 there have been at least nine fatalities in Europe caused by carbon monoxide poisoning following entry into wood pellet storage areas. Although there have not been any incidents so far in the UK the use of wood pellets is increasing and awareness of this danger is required. Wood pellet boilers are used in homes and businesses as an alternative to oil or gas fired boilers. They are also being installed to replace coal-fired boilers, particularly...
Espaces clos : la prudence est de mise
Les espaces clos, selon leur emplacement, leur conception et leur contenu, comportent des dangers importants pour la santé et la sécurité des travailleurs. Chaque année, au Québec, près de 40 travailleurs sont victimes d'accidents graves et mortels pendant qu'ils travaillent en espace clos. La plupart des décès sont reliés à une déficience en oxygène ou à la présence de gaz toxiques ou inflammables. Par ailleurs, on estime que 60 % des victimes d'accidents fatals sont des personnes ayant...
Pour prévenir une intoxication au monoxyde de carbone, attention aux chariots élévateurs
Le monoxyde de carbone (CO) est un gaz sournois parce qu'il est invisible, inodore et toxique. On l'appelle aussi le tueur silencieux. Le CO pénètre dans le corps humain par les voies respiratoires et prend la place de l'oxygène. Les chariots élévateurs au propane sont souvent la cause des intoxications au CO dans les milieux de travail. Il est possible de contrôler les émanations de CO et de prévenir une intoxication. Voici un aide-mémoire des principales mesures de prévention à adopter. Source : http://www...
Evaluation of Carbon Monoxide Exposure Among Airport Cargo Material Handlers
he Health Hazard Evaluation (HHE) Programme evaluated airport cargo handlers' exposure to carbon monoxide. Investigators found that all airport terminal service employees' carbon monoxide levels measured in the evaluation were above recommended limits but transportation security and air logistics employees' carbon monoxide levels were not. Investigators recommended replacing fuel-driven forklifts and tugs with electric ones, reminding drivers to turn off vehicle engines when at the dock doors, increasing warehouse ventilation, and installing carbon monoxide alarms.
