Norbar has published recent test results carried out by the HSE (Health & Safety Executive). The toolmaker reports that they demonstrate that vibration exposure for operators using pneumatic torque multipliers to tighten 100 commercial vehicle wheel nuts was 10 times lower with its products than when traditional impact wrenches are used. The Norbar Pneutorque PTM-72-1350B and one other multiplier were subjected to lab and field tests by the HSE and both tools confirmed manufacturer claims of low vibration emissions.

Low vibration levels help avoid occupational risks such as VWF (vibration white finger) also known as HAVS (hand arm vibration syndrome). In addition, the Control of Vibrations at Work Regulations impose a Daily Exposure Action Value (EAV) of 2.5 m/s2, above which employers must introduce controls to eliminate or reduce exposure and provide health surveillance to operators regularly exposed to vibration that exceeds this level. According to the company, the Norbar Pneutorque pneumatic torque multiplier does not exceed 2.5 m/s2. This means there is no restriction in its use during the working day.
