| Summary: | Thesis (MTech (Environmental Health))--Peninsula Technikon, Cape Town, 2004 === AIM &; OBJECTIVES: a) To quantify human vibration exposnres among the various similar
occupational groups present on the mine, b) To determine the degree of vibration risk posed onto
the mineworkers and c) To recommend and implement a sustainable human vibration management
control progranune.
METHODOLOGY: A cross-sectional descriptive study design was carried out on 135 mine
workers employed in various similar occupational groups at Rossing Uranium mine, Namibia Data
acquisition originated from a multi-stage proportionally stratified random sampling technique. An
approved Human Vibration measuring instrument was utilized to measure Hand-arm and
Wholebcdy vibration exposure levels [Aeq (m/s2
)] prevalent among the similar exposure groups. A
structured questionnaire, developed specifically for the actual work environment enabled the
collection of information such as work history, type of vibration exposure, exposure duration and
vibration symptoms. Furthermore, group specific results [A(8)] were computed by means of the
latest internationally accepted Health & Safety Executive Vibration calculators. In addition,
statistical analyses were performed in order to establish the occupational groups that are at
increased risk for the development of hand-arm and wholebody vibration induced health disorders.
