Paschold, Helmut W. Vibration in the occupational and general environmental settings can be manifested in many ways according to frequency, magnitude, or medium and subsequent effects on the human body. Frequency ranges with potential risk to humans can range from less than one cycle per second Hertz - Hz to hundreds of thousands. The vibration ranges to be considered are Whole Body Vibration ranging from 0. Both WBV and noise are acknowledged as having potential to causing harm to the human body. Safety and health SH professionals address hazards through anticipation, recognition, evaluation, and control. The anticipation and recognition of noise hazards can be considered a basic skill set among SH professionals.

Сюда. В этой встрече было что-то нереальное - нечто, заставившее снова напрячься все его нервные клетки. Он поймал себя на том, что непроизвольно пятится от незнакомцев. Тот, что был пониже ростом, смерил его холодным взглядом. - Сюда, мистер Беккер. Быстрее. Беккер повернулся и побежал, но успел сделать только один шаг.
Может быть, я так и сделаю. - Mala suerte, - вздохнул лейтенант. - Не судьба. Собор закрыт до утренней мессы. - Тогда в другой .
