Measuring methods of the gas concentration in the working area air of the mechanical-engineering repair facilities are considered. The gas-sensitive sensor types are compared. A classification of the occupational hazards is presented; their health effect is described. The object of this study is a standard repair facility of the mechanical-engineering industry. The workplace assessment charts of one of the electric locomotive repair works are analyzed. Some issues on the acceptable working conditions ensuring, and on decreasing their harmful level are considered. To solve the task of monitoring the occupational hazards, the application of the wireless sensor networks (WSNs) is proposed. The sensor types best suited for the application in the WSN are described. The results of the research conducted allowed making the conclusions on the feasibility of the wireless sensor networks in the safety management systems in the mechanical-engineering repair facilities.

Методы контроля опасных и вредных производственных факторов на ремонтных предприятиях машиностроительной отрасли[1]
М. Н. Мохсен, М. А. Журавлева
Рассматриваются методы измерения концентрации газов в воздухе рабочей зоны машиностроительных ремонтных предприятий. Сравниваются типы газочувствительных датчиков. Приводится классификация вредных и опасных производственных факторов, описывается их влияние на организм человека. В качестве объекта исследования выступает типовое ремонтное машиностроительное предприятие. Проведен анализ карт аттестации рабочих мест одного из цехов электровозоремонтного завода. Рассмотрены вопросы обеспечения допустимых условий труда и снижения степени их вредности. Для решения задачи мониторинга опасных и вредных производственных факторов предложено применение беспроводных сенсорных сетей (БСС). Описаны типы датчиков, наиболее подходящих для использования в БСС. Результаты проведенного исследования позволили сделать выводы о практической применимости технологии беспроводных сенсорных сетей в системах управления охраной труда машиностроительных ремонтных предприятий.
Ключевые слова: беспроводные сети датчиков, беспроводные сенсорные сети, вредные и опасные производственные факторы, класс опасности, ремонтное предприятие.
