Vibration data and trigger-time calculator
Calculate this tool’s exposure
Other tools in your current tab’s daily draft are kept when you add this tool. Review the combined daily total in the calculator.
Time and points at your selected magnitude
Times assume no other exposure that day and are rounded down to whole minutes. These thresholds are not safe-time allowances. Keep exposure as low as reasonably practicable.

Declarations are test results, not workplace measurements. The starting estimate uses the higher of an assigned HSE tool-type value and declaration plus K where available. K is test uncertainty, not a workplace correction factor. This is Handarm’s starting rule, not an HSE model-specific recommendation or guaranteed upper bound. Use your employer’s assessed value where appropriate.
Current and historical sources are included; catalogue coverage and UK sales status are not fully verified. Missing or ambiguous figures require assessment.
