The Pesticide Users Health Study (PUHS) was established so as to monitor the health of men and women who are certified to apply pesticides on a commercial basis under the 1986 Control of Pesticides Regulations. An analysis of deaths occurring between 1987 and 2005 among members of the PUHS is presented in this report. There were 1,628 deaths among 59,085 male and 3,875 female pesticide users during the follow-up period. Compared with the population of Great Britain, the pesticide users had lower than expected mortality from all causes, and in particular from all cancers combined, cancers of the digestive organs, cancers of the respiratory system, and non-malignant diseases of the nervous system and sense organs, and of the circulatory, respiratory, and digestive systems. There was some evidence of excess deaths from multiple myeloma in men and women, and possibly also from testicular cancer. Deaths from all external causes (accidents and injuries) combined were lower than expected when compared with the general population. However in men, deaths from ‘injury by machinery’ were higher than expected. Continuing recruitment into the PUHS will enable HSE to monitor the health of these pesticide users as regulations and exposures change over time.

OSHA has issued a new booklet, "Firefighting Precautions at Facilities with Combustible Dust," to aid emergency responders who may face fires and explosions caused by combustible dust. The primary purpose of this document is to protect emergency responders from harm by giving them a framework for gathering the necessary information prior to an emergency and converting it into safe operating procedures. In this document, emergency responders include firefighters, fire
brigade members, hazardous materials teams, and others who might be called upon to respond when a fire or explosion occurs. This document is not intended to provide specific strategies or tactics to be used during emergency responses. It does, however, discuss some tactics that should be considered. The information
presented here and collected during pre-incident surveys should be used to train all emergency responders on how to properly handle incidents at facilities with combustible dusts

This NIOSH Current Intelligence Bulletin (1) reviews the animal and other toxicological data relevant to assessing the potential non-malignant adverse respiratory effects of CNT and CNF, (2) provides a quantitative risk assessment based on animal dose-response data, (3) proposes a recommended exposure limit (REL) of 1 μg/m3 elemental carbon as a respirable mass 8-hour time-weighted average (TWA) concentration, and (4) describes strategies for controlling workplace exposures and implementing a medical surveillance program. The NIOSH REL is expected to reduce the risk for pulmonary inflammation and fibrosis.
Background: In order to make full use of the opportunities while responsibly managing the risks of working with manufactured nanomaterials (MNM), we need to gain insight into the potential level of exposure to MNM in the industry. Therefore, the goal of this study was to obtain an overview of the potential MNM exposure scenarios within relevant industrial sectors, applied exposure controls, and number of workers potentially exposed to MNM in Dutch industrial sectors producing and applying MNM-enabled end products in the Netherlands. Methods: A survey was conducted in three phases: (i) identification of MNM-enabled end products; (ii) identification of relevant industrial sectors; and (iii) a tiered telephone survey to estimate actual use of the products among 40 sector organizations/knowledge centres (Tier 1), 350 randomly selected companies (Tier 2), and 110 actively searched companies (Tier 3). Results: The most dominant industrial sectors producing or applying MNM-enabled end products (market penetration >5%) are shoe repair shops, automotive, construction, paint, metal, and textile cleaning industry. In the majority of the companies (76%), potential risks related to working with MNM are not a specific point of interest. The total number of workers potentially exposed to MNM during the production or application of MNM-enabled end products was estimated at approximately 3000 workers in the Netherlands. The results of this study will serve as a basis for in-depth exposure and health surveys that are currently planned in the Netherlands. In addition, the results can be used to identify the most relevant sectors for policy makers and future studies focussing on evaluating the risks of occupational exposure to MNM.

Un récent avis de l'Anses met en garde sur les risques potentiels liés au bisphénol A (BPA) pour les enfants à naître. L'exposition des femmes enceintes pourrait en effet induire des modifications de la structure de la glande mammaire du fœtus susceptibles de favoriser l'apparition de cancers du sein. L'alimentation constitue la principale source d'exposition mais les travaux ont également permis d'identifier des situations d'exposition professionnelle notamment lors de la manipulation des papiers thermiques (tickets de caisse, reçus de cartes bancaires…). L'INRS propose par ailleurs un « questions/réponses » qui présente les principales informations sur le BPA au travail : utilisations, risques, expositions, mesures de prévention…

The Pesticide Users Health Study (PUHS) consists of pesticide users certified under the Control of Pesticides Regulations 1986 (COPR). This report presents cancer incidence experienced by pesticide users in the PUHS, and compares this to the rates observed in the national population.
Altogether, there were 1,720 registered cancers among 62,960 pesticide users between 1987 and 2004. Men in the PUHS had reduced overall cancer incidence compared to the national population. In particular, incidence of cancer of the lip, oral cavity & pharynx, cancer of the digestive organs, cancer of the respiratory system, and cancer of the urinary system were significantly below the numbers expected. Incidence of cancer of the testis and multiple myeloma were elevated among men in the PUHS, and incidence of non-melanoma skin cancer was elevated among both males and females.
The Health & Safety Executive should continue to recruit and follow-up pesticide users in the PUHS in order to monitor their health. Information collected through future research could be used to enhance analysis of cancer incidence among members of the PUHS, and control for potential confounding factors.

The Pesticide Users Health Study is a cohort of nearly 66,000 commercial pesticide users, certified under the 1986 Control of Pesticide Regulations, who had agreed to participate in HSE’s programme of research into their health. A survey to assess the history of pesticide usage among members of this cohort, and to assess the level of self-reported ill health associated with pesticide exposure, was undertaken in two waves during 2004 and 2006. The response rate (14%) to the questionnaire was very low; this may be partly attributable to a general decrease in survey response rates and to the fact that the main wave of the survey was undertaken at a particularly busy time of year. Respondents listed nearly 2,500 unique trade names and 677 active ingredients. The most common areas of pesticide usage were amenity weed control and the treatment of cereals. Individuals who were often exposed to pesticide concentrate were four times more likely to report 'ill health' associated with pesticide use than those exposed to diluted products; additionally individuals who had used pesticides in jobs lasting more than 15 years were more likely to report 'ill health' than those working in jobs lasting less than 5 years.

In Ontario, asbestos remediation requires full-body protective coveralls, head coverings, and other personal protective equipment such as respirators, gloves, and boots. These types of protective clothing can put workers at increased risk of developing heat-related illnesses. The Insulators Labour-Management Health and Safety Committee, in partnership with IHSA, has developed a Health and Safety Advisory on this issue

In an atmospheric HAZMAT release unprotected public dermal exposure is often of short duration, but with potential secondary exposure if not decontaminated promptly. Mass decontamination is resource intensive and needs to be justified. For many HAZMAT agents there is no evidence-base on which to provide guidance on decontamination, particularly for non-symptomatic worried well. It is important to understand the influence of street clothing and environmental and other factors. Ammonia is a common HAZMAT agent and was selected for in vitro human skin studies of absorption, penetration and off-gassing at test concentrations up to 2000 ppm, incorporating primary and secondary exposure combinations up to 60 min.
Intact skin provided a good barrier to ammonia penetration. Heavy street clothing such as denim was found to act as an initial barrier to skin absorption but subsequently as a reservoir for secondary exposure, under variable temperature and humidity conditions. Rapid off-gassing was observed for lighter fabrics including polyester and cotton. The findings here have been summarized as a set of practical guidelines for emergency responders who are required to make decisions about ammonia decontamination including for non-symptomatic individuals. This evidence-based diagrammatic approach allows for specific actions based on different atmospheric ammonia concentrations and other parameters.

Objectives Trichloroethylene (TCE) and Perchloroethylene (PER) are two chlorinated solvents that are applied widely as degreasers of metal parts, and in dry cleaning and other applications. In 2012, the International Agency for Research on Cancer classified TCE as carcinogenic to humans and PER as probably carcinogenic to humans. We explored exposure–response relations for TCE and PER and non-Hodgkin's lymphoma (NHL), multiple myeloma (MM), and cancers of the kidney and liver in the Nordic Occupational Cancer cohort. Methods The cohort was set up by linking occupational information from censuses to national cancer registry data using personal identity codes in use in all Nordic countries. Country, time period, and job-specific exposure estimates were generated for TCE, PER and potentially confounding occupational exposures with a job-exposure matrix. A conditional logistic regression was conducted for exposure groups as well as for continuous cumulative exposure. Results HRs for liver cancer, NHL and MM but not kidney cancer were slightly elevated in groups with high exposure to PER (compared to occupationally unexposed subjects). HRs for liver cancer and NHL also increased with increasing continuous exposure to PER. We did not observe evidence for an association between exposure to TCE and NHL, MM or liver and kidney cancer. Conclusions Although this study was subject to limitations related to the low prevalence of exposure to PER and TCE in the Nordic population and a limited exposure assessment strategy, we observed some evidence indicative of an excess risk of cancer of the liver and NHL in subjects exposed to PER.
