Détection moléculaire des bactéries du genre Légionella dans l’eau des tours de refroidissement et l’eau de consommation

Les bactéries du genre Legionella sont répandues dans plusieurs environnements tant naturels qu'artificiels. Les concentrations rencontrées dans les environnements naturels sont très faibles. Les phénomènes de contamination se rencontrent principalement dans les réservoirs artificiels où les températures de l'eau sont maintenues entre 25 et 42 °C, et où existe une certaine stagnation ainsi que la présence de dépôts, de biofilms et d'amibes. Les bains à remous, les piscines, les condensateurs d'évaporation, les brumisateurs et les tours de refroidissement sont reconnus comme étant des sources responsables de l'éclosion de légionellose en raison de la croissance importante des bactéries du genre Legionella dans ces milieux.

Adherence to Precautionary Guidelines for Compounding Antineoplastic Drugs

A Survey of Nurses and Pharmacy Practitioners
Precautionary guidelines detailing standards of practice and equipment to eliminate or minimize exposure to antineoplastic drugs during handling activities have been available for nearly three decades. To evaluate practices for compounding antineoplastic drugs, the NIOSH Health and Safety Practices Survey of Healthcare Workers was conducted among members of professional practice organizations representing primarily oncology nurses, pharmacists, and pharmacy technicians. This national survey is the first in over 20 years to examine selfreported use of engineering, administrative, and work practice controls and PPE by pharmacy practitioners for minimizing exposure to antineoplastic drugs. The survey was completed by 241 nurses and 183 pharmacy practitioners who compounded antineoplastic drugs in the seven days prior to the survey. They reported: not always wearing two pairs of chemotherapy gloves (85%, 47%, respectively) or even a single pair (8%, 10%); not always using closed system drug-transfer devices (75%, 53%); not always wearing recommended gown (38%, 20%); I.V. lines sometimes/always primed with antineoplastic drug (19%, 30%); and not always using either a biological safety cabinet or isolator (9%, 15%). They also reported lack of: hazard awareness training (9%, 13%); safe handling procédures (20%, 11%); and medical surveillance programs (61%, 45%). Both employers and healthcare workers share responsibility
for adhering to precautionary guidelines and other best practices. Employers can ensure that: workers are trained regularly; facility safe-handling procedures reflecting national guidelines are in place and support for their implementation is understood; engineering controls and PPE are available and workers know how to use them; and medical surveillance, exposure monitoring, and other administrative controls are in place. Workers can seek out training, understand and follow facility procedures, be role models for junior staff, ask questions, and report any safety concerns.

ECHA publish proceedings from the Topical Scientific Workshop on Regulatory Challenges in the Risk Assessment of Nanomaterials

The European Chemicals Agency (ECHA) has published proceedings from the Topical Scientific Workshop on Regulatory Challenges in the Risk Assessment of Nanomaterials, which was held on the 23rd – 24th October 2014 in Helsinki.
The workshop brought together close to 200 experts in the field of risk assessment of nanomaterials representing academia, policy makers, industry and non-governmental organisations (NGOs), and provided a unique platform for academia and regulators to discuss how to address current challenges from the regulatory perspective, which can be reflected and employed in the on-going and future research topics on nanomaterials. The discussions were reinforced by information of the recent developments and of risk assessment methodologies applied in chemicals management both within and outside the European Union (EU).

Avec [email protected], l'INRS aide les entreprises à évaluer le niveau d'empoussièrement aux fibres amiante lors de la mise en œuvre de processus sur matériaux amiantés.
Évaluer a priori le risque amiante, c'est ce que propose l'outil [email protected]. Disponible en ligne, il permet  aux entreprises concernées par ce risque d'évaluer le niveau d'empoussièrement émis par leur processus, selon la catégorie d'activité dans laquelle s'effectuent les opérations (dites sous-section 3 pour les travaux de retrait et d'encapsulage et sous-section 4 pour les interventions sur les matériaux amiantés), par nature du matériau et par technique utilisée.

The Breast Cancer Fund: Working Women and Breast Cancer

The State of the Evidence
Based on the current evidence, action to reduce workplace exposures linked to breast cancer is imperative. The Breast Cancer Fund has spent nearly 15 years translating the science that links environmental exposures to breast cancer, and advocating for change. In the past several years, it has become increasingly evident that the workplace may be a substantive source of many of these exposures and of the resulting risk for breast cancer.

Pollution de l’air dans les enceintes ferroviaires souterraines et risques pour la santé des travailleurs

La qualité de l'air dans les enceintes ferroviaires souterraines constitue un objet de préoccupation depuis plusieurs années. Compte tenu de la pollution de l'air mise en évidence dans ces enceintes et des durées de fréquentation des travailleurs y exerçant leur activité professionnelle, des interrogations se posent sur les risques sanitaires à long terme liés aux polluants de l'air présents dans ces enceintes et encourus par ces professionnels. C'est pourquoi l'Anses a été saisie de cette question par les ministères en charge de la santé, du travail et de l'environnement.

Summary of work undertaken to assess workplace exposure and control measures during the manufacture and handling of engineered nanomaterials

The aim of this research was to develop an improved understanding of the UK nanomaterial industry and of worker exposure to engineered nanomaterials, through visits to companies manufacturing or using these materials. The visits were undertaken to assess exposure to airborne nanomaterials and to assess the effectiveness of the controls used to reduce exposure.
