Abstract Solid-liquid filtration processes are crucial for the production of beer. Clarification of the green beer generates a clear and bright product with extended colloidal and microbiological shelf live. Conventionally, clear filtration is based on pre-coat filtration using filter aids, such as diatomaceous earth (Kieselguhr). However, the application of Kieselguhr requires strict adherence to occupational safety and health protection, as it is classified as a hazardous substance by the World Health Organisation and can lead to lung diseases. Furthermore, significant amounts of waste filter aids are generated. An alternative to pre-coat filtration is microfiltration that avoids the generation of hazardous wastes. Microfiltration can also be applied in beer yeast treatment. This article highlights major concepts and restriction of the filtration processes.

Health begins at home and in community where people live and work, in fact, the World Health Organisation (WHO) defines health as ‘a state of complete physical, mental and social well-being’. Experts and professionals, of all sectors and specialities, need to take account the Occupational Safety and Health (OSH) in all aspects of their working lives. Mainstreaming OSH into education concerns integrating one policy area – OSH – into another – education. This study started from a first analysis of an international and national OSH training offer, in which  some critical aspects emerged: there are mostly sectoral training courses, qualifying some prevention actor roles, most linked to traditional risks, and primarily focused on the safety aspects rather than the health ones. The current study is related to an innovative format and experience for an integrated management of OSH in the evolution of the world of work. The concept was born from the need to train new professionals figures when the rapid demographic changes and technological innovation are changing the working world and therefore also the required skills to prevention actors. A first test has been conducted on 26 students who attended the first edition of this innovative training.

ABSTRACT Oil spill response personnel encounter commercial diving operations during salvage and pollution response operations. During an oil spill or hazardous substance release, the National Contingency Plan requires that response operations, including commercial diving operations, be conducted in accordance with the requirements, standards, and regulations of the Occupational Safety and Health Administration. Additionally, the Coast Guard requires that commercial diving contractors meet their own commercial diving regulations (46 CFR 197) during response operations. Incident commanders and safety officers should ensure that an inspection of the on-site diving operation is conducted to confirm that commercial diving personnel, operations, and equipment meet the applicable regulations. This technical paper provides guidance to response personnel on the inspection of commercial diving operations during marine response operations and an overview of the equipment used to protect divers in contaminated waters. Additionally, this guidance provides checklists to facilitate the inspection of commercial diving operations to protect the health and safety of commercial divers.

The World Health Organisation (WHO) launched the Surgical Safety Checklist in 2008. The introduction of this checklist resulted in a significant reduction in the incidence of complications and death in patients undergoing surgery. Consequently, the WHO Surgical Safety checklist is recommended for use by the National Patient Safety Agency for all patients undergoing surgery. However, many invasive or interventional procedures occur outside the theatre setting and there are increasing requirements for a safety checklist to be used prior to such procedures. Transoesophageal echocardiography (TOE) is an invasive procedure and although generally considered to be safe, it carries the risk of serious and potentially life-threatening complications. Strict adherence to a safety checklist may reduce the rate of significant complications during TOE. However, the standard WHO Surgical Safety Checklist is not designed for procedures outside the theatre environment and therefore this document is designed to be a procedure-specific safety checklist for TOE. It has been endorsed for use by the British Society of Echocardiography and the Association of Cardiothoracic Anaesthetists.

Odorants are released during the decomposition of organic waste at compost treatment plants. Composting releases volatile organic chemicals (VOCs), including alcohols, aldehydes, volatile fatty acids, ammonia and other nitrogen compounds, xenobiotic solvents, and various sulphur compounds into the environment as categorised by a compost odor wheel. Each odorant possesses a characteristic odour signature – quality and threshold as well as a toxicity value. This paper presents data relating the human odour detection limit to human health threshold criteria developed by the National Institute for Occupational Safety and Health, Occupational Safety and Health Administration, the United States Environmental Protection Agency Region 9 and the World Health Organisation. This comparison indicates that: (1) the human odour threshold concentrations (OTC) for most compost odorants are far lower than their respective human health risk (regulatory) threshold values, (2) several compost odorants have OTC that are below some of their respective regulatory thresholds and above others (i.e. dimethyl amine, formic acid acetone, ethyl benzene and toluene) and (3) only the VOCs probably present as contaminants in the raw composting material have OTC greater than all of its regulatory thresholds (i.e. benzene). Benzene is the most hazardous VOC associated with composting and should be monitored.


screen. Chemicals which are shown to be mutagenic in Phase I assays progress to Phase II. In addition, a certain number of chemicals giving negative results in Phase I are committed also to further testing in Phase II, based primarily on known biological activity of structurally related compounds, and on estimated levels of human exposure. Chemicals which are positive mutagens in Phase progress to Phase III. III. WORLD HEALTH ORGANIZATION'S (WHO) INTERNATIONAL AGENCY FOR RESEARCH ON CANCER (IARC) IARC Monographs on the Evaluation of the Carcinogenic Risk of Chemicals to Humans In the World Health Organization's International Agency for Research on Cancer (IARC) initiated a program of evaluation of the carcinogenic risk of chemicals to humans. "The objective of the program to elaborate and publish in the form of monographs, critical reviews of data on carcinogenicity for groups of chemicals to which humans are known to be exposed, to evaluate these data in terms of human risk . . . and to indicate where additional research efforts are needed." The IARC Monographs are recognized an authoritative source of information on the carcinogenicity of environmental chemicals. The first users' survey, made in 1976, indicates that the monographs are consulted routinely by various agencies in 24 countries. IV. OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION (OSHA) A List of Substances Which May Be Candidates for Further Scientific Review and Possible Identification, Classification and Regulation Potential Occupational Carcinogens. Publication of this list by the Occupational Safety and Health Administration the first action taken in following the "Cancer Standard" procedures promulgated by OSHA in January, 1980.

Only 15% of the global population has access to occupational safety and health services. In Africa, only 5% of employees working from major establishments have access to occupational health services (OHS). Access to primary health care (PHC) services is addressed in many settings and inclusion of OHS in these facilities might increase efficiency in preventing occupational diseases. A cross-sectional study was conducted in four Southern African Development Community (SADC) countries aiming at assessing the availability of OHS at PHC facilities and the organization of OHS. We conducted a literature review to assess the provision and organization of OHS services. In addition to the review, a total of 23 doctors from Zambia were interviewed using questionnaires in order to determine the availability of OHS and training. Consultations with heads of ministries were done in four SADC countries. Results showed that in the SADC region, OHS are fragmented and lack a comprehensive approach. In addition, out of 23 PHC facilities, only two (13%) provided occupational health and PHC. However, OHS provided at PHC facilities were limited to TB screening and audiometric testing. Our study showed a huge inadequacy of trained occupational health practitioners. This study supports the World Health Organization’s advocacy to integrate OHS at the PHC level.

Asbestos collectively refers to a set of naturally existing silicate minerals with fibrous structures, and is a natural mineral in fibrous forms that was originally serpentines or amphiboles. Because of its properties such as resistance to heat, chemical resistance and corrosion; tensile strength; sound absorption; and affordable prices, it had been widely used as building materials, fire resistant and retardant, thermal and heat insulation, sound absorbent, and electrical insulation. Since the prolonged inhalation of asbestos can cause serious illnesses such as lung cancer, mesothelioma, and asbestosis after an incubation period of 20 to 40 years, the mineral was classified as Group 1 carcinogen by the International Agency for Research on Cancer. In Korea, asbestos-containing construction materials had been widely used until asbestos was added to the hazardous substance requiring permission for use by the Occupational Safety and Health Act, and use of asbestos was totally banned in February 2009. This survey was conducted with 45 buildings to assess asbestos-containing materials used by usage of building. It was found that asbestos-containing construction materials were used in 27 buildings out of 45 buildings surveyed.
