Vibration Exposure Risk Assessment at Work



Many customers are required to make Vibration Exposure Risk Assessments in their factory or place of work.

Our Health and Safety at Work section details the wide range of instruments we hire and the HSE web-site describes the Noise at Work Regulations. This page is for the customer who wants to hire equipment that others are using to meet these requirements and make the following measurements

HAVS monitoring

Hand Arm Vibration - HAVS

Vibration White Finger - VWF

Whole Body Vibration - WBV and VDV.

All our meters, and calibrators are delivered with traceable certificates.

It is good practice to use a calibrator on-site before and after each measurement and log the fact with all serial numbers in the report.

Vibrock v901 Delivered with one triaxial PPV - peak particle velocity transducer and a triaxial VDV vibration dose transducer **.

The PPV vibration transducer details are detailed here

VDV - Vibration Dose Value
When using the VDV vibration dose transducer, the instrument complies with BS 6472 and BS 7482 part 3 with automatic day/night change over. Both 30 second and 1 hour dose levels are recorded and the resultant 16 or 8 hour values calculated in the range 0.025 to 10 m/s- 1.75.

Ideal for whole body vibration measurements when the operator is standing on the vibrating surface. You can still record the PPV levels etc., on the other channel.

Vibrock V901 Specifications

Robust, weatherproof and lightweight - kit also includes PC download software with a cable.

The transducer leads are 1.2 m long, order extension cables if required.

** If you want to use the second channel for additional PPV type measurements, then add an extra PPV transducer and suitable extension cables
