Noise & Vibration

Noise-Measurement-In-PerthNoise Survey

Excessive noise in the workplace has been shown to be a major cause of deafness as well as contributing to injuries, accidents and a reduction in productivity and worker performance. Permanent hearing loss caused by sudden extreme exposure or prolonged long-term exposure to noise is incurable.

Eosh conducts noise assessments of individual items and equipment in plants and factories, as well as overall workplaces for the presence of noise sources that may be potentially harmful to the hearing of the workforce. Noise monitoring and noise control strategies are required by occupational safety and health law in all workplaces where noise may be excessive.

Eosh conducts identification of noise hazards in the workplace allowing:

Identification of sources of excessive noise

  • Determining those persons who may be exposed (Similar Exposure Groups) above the acceptable noise exposure standard
  • Determination of noise control measures required.
  • Assessment of adequacy of current personal hearing protection and recommendation of alternatives

Eosh helps with the development and implementation of programs of regular noise measurement to monitor the continued effectiveness of noise controls that are currently in place. In the past, these have been developed where it is determined that work processes or workplace design may vary through a project life cycle and therefore it is deemed necessary to focus on excessive noise in particular.

Vibration Assessment

Hand-Arm Vibration (HAV) is commonly caused by the repeated use of items of vibrating hand held tools such as chain saws, drills, grinders and pneumatic Jack Hammers. Health hazards such as Vibration Syndrome and Vibration Induced White Finger (VWF) are related to the use of vibrating tools where the action and motion of the tool is transmitted to the operators hand.

Whole Body Vibration (WBV) exposure caused by vibration transmitted through a supporting surface such as the seat of a vehicle is found to be associated with symptoms such as fatigue, insomnia, stomach problems, headaches and hakiness¬Ě shortly after or during exposure and long term effects such as lower back injuries and spinal disorders.

Eosh uses the latest equipment to undertake vibration assessments and determination of potential exposures through measurement of locations such as work stations and driving cabs along with specific items of equipment. Representative exposure levels are then compared to recommended or regulatory determined exposure levels. Assessments are conducted during normal operating conditions where practicable to determine potential exposures accurately.
