The analysis of the medical and social aspects occupational noise-induced hearing loss (NIHL) on basis its phenomenology is presented. ear as an information receiver frequency range voice communication are considered. NIHL classifications in Russia, starting with GOST 12.4.062-78 described, overview international (WHO, 2011; ILO, 2013; UKOOA, 2003) national (Belgium, France, USA) criteria outlined. As example a civil aviation pilot audiogram was compared to different criteria; it shown that...

An analysis of the documents WHO, ILO, European Union, etc., a review literature and essays on problem assessing professional risk healthcare workers in light COVID-19 pandemic, as well protection prevention measures. A pandemic is public health occupational medicine since are at forefront fight against epidemic for life population themselves extreme risk. On issues labor workers, most women, there lot works; ILO Nursing personnel Convention No. 149: Recognize their contribution, address...

Introduction. Revision of the "Guidelines for hygienic assessment factors working environment and labor process. Criteria classification conditions" R 2.2.2006-05 determined relevance improving criteria conditions, including noise, based on a risk-based approach. The study aims to substantiate risk-oriented conditions by taking into account group attributive (excessive) risk hearing loss. Materials methods. researchers carried out an expert-analytical calculations loss under influence noise....

Introduction. Recent studies have shown that working conditions at mining enterprises remain harmful and dangerous. We characterize the by a set of factors production environment affect functional state body workers their capacity. It depends on equipment used, technologies, objects, products labor. They are specific to each enterprise. In these conditions, definition occupational risks violation health miners becomes particularly relevant. The study aims assess current professional...

Introduction . Prevention of occupation hearing loss should be based on mathematical models and computational methods to predict changes in thresholds (HT) with age under the action noise organ. There is an urgent need for quantitative determine health risk exposure above 80 dBA. The aim study was group excessive (ERHL) using model third edition ISO 1999. Materials Developed technology determination HT model, 1999, depending gender, age, length service experienced basis related sett lement...

Introduction The optimal indicators and adequate criteria for the quantitative assessment of hearing loss excess risk with noise exposure above 80 dBA is urgently needed determination. Methods technology calculating thresholds according to model third edition ISO 1999.3:2013 standard, depending on gender, age, length service exposure, based MSExcell tables, population percentiles 1÷99% in 1% steps has been developed. Rules selecting early signs occupational noise-induced have Result men...

Periodic medical examinations (PME) of working population exposed to impact harmful and dangerous factors environment do not provide timely detection occupational pathologies, what results in progress persistent loss capacity the period activities. Among reasons situation, there is absence lists persons subjected PME, data on conditions for assessment antecedent risk disease progress, as well approved methods their health indicators according PME establishment cause-effect relations with...

Methodology of occupational risk management is outlined based on workers’ health disorders forecast and causation (work-relatedness assessment). It originates from Labour Code Russian Federation prescriptions includes principles, methods criteria communication. The methodology realized by means bioinformational technologies as expert analytical system in the form interactive Web-based directory «Occupational assessment» for practical use prevention.

The analysis of the international and national documents review scientific literature from positions evidential medicine on overtime works (OTW). Conventions recommendations ILO, directives European Union also requirement for OTW are reviewed. Questions occupational risk at considered needs additional protective measures medical care workers noted.

Full vibration acceleration, as an estimated and normalized parameter of the characteristics machines acting on a person, is used to regulate effect in regulatory documents European Union (EU). In Russian practice, maximum «corrected acceleration» measured for each direction basicentric coordinate system these purposes. Both evaluation principles are compared using examples measurements from various sources safe duration typical operating conditions vibroactive equipment. For exposures most...

The intensity of civil aircraft flights elevates with the increase in number passenger and cargo transportation by air. Aircraft noise residential area near airports grows up too despite use low-noise models airlines. This causes an augmentation complaints population these areas. Russian Federation’s normative methodological documents requirements force relating to measurements assessment areas, including «aircraft noise», were analyzed. Their terms measuring assessing “aircraft noise”,...

Introduction. The transfer function of the outer ear is an important characteristic hearing organ, determined by acoustic properties auricle and external auditory canal, their shape size. impedance eardrum also likely to matter. frequency characteristics transmission must be taken into account when choosing individual noise protection devices prosthetics organs. Measurements sound pressure distribution along canal carried out various researchers with a probe microphone have shown that for...

The article discusses the issues of adjustment, developed in 2007 and supplemented 2009, methodology for evaluating equivalent level cabin noise civil aviation aircraft Russia. relevance problem is due to high levels professional hearing loss among aircrew members air force, which directly related lack unified competent approaches assessing acoustic load on organ members. updated contains full-fledged data modern domestic foreign airliners, certification efficiency accessories, a direct...

Introduction: To solve the tasks of preventing occupational diseases in workers mining industry, it is important to substantiate physiological indicators tension regulatory systems human body under negative impact industrial noise and neuro-emotional work intensity assess effectiveness hearing personal protective equipment (PPE). Our objective was identify characteristics adverse functional changes various professions industry exposed combined effect use protection devices. Materials...

The use of liquefied gases in the modern world is quite promising: thermal energy, chemical production, capacity natural gas motor fuel. Certain calculations show that transporting (LNG) over long distances less expensive than supplying through main pipelines. Another argument favor LNG geography fields: regions Far North are adjacent to Northern Sea Route. equipment plants for production metal-consuming. At same time, overwhelming majority metal products used respective operated at boiling...

Hygienic rationing is an integral part of national measures in the field occupational safety and health workers. The current norms general industrial vibration, as known, are not safe. This determines urgency improving system hygienic which, despite achievements science technology, emergence a new controlled vibration parameter — full acceleration, introduction risk-based approach to rationing, has remained virtually unchanged for almost four decades. study aims analyze domestic...
