Features

  • I.S. approved for hazardous and potentially explosive atmospheres
  • Accurately capture the trigger time
  • Button push setup - no software needed

Applications

  • Hand arm vibration
  • HAVS risk assessment
  • Oil and gas industry
  • Petrochemical plants

The Intrinsically Save HAVi Hand Arm Vibration Monitor works in the same way as the standard HAVi monitor. It tracks the length of time that a worker is exposed to power tool vibration. Given the vibration magnitude for the tool, it then calculates the total exposure and displays the HSE points.

The HAVi monitor is attached to the power tool using the strap or ties provided - no glue or other permanent fixing so it can be easily moved between tools.

After selecting the vibration magnitude for the tool (done using the buttons on the front), the HAVi detects the tool being started and accurately tracks the time used. This avoids a common problem of workers over-estimating the length of time that the tool was actually powered and in use. See the Using It tab above for more details.

The HAVi shows the vibration exposure in m/s2 along with the HSE points (so you don't have to work them out) and the trigger time.

Using the HAVi

The HAVi-IS is used to help you assess the level of vibration that workers are exposed to when using various power tools. The exact details of a full HAVS risk assessment may vary, but in general consists of:

  • Find the vibration magnitude figure for each tool - provided by the tool manufacturer or measured using a Vibration Meter
  • Find out how long the tool is used for
  • Calculate the worker's total exposure (based on magnitude and time)

The HAVi makes this process easier and more accurate by measuring the length of time the tool is used for and by calculating the total exposure, even providing you with the HSE points that are used for the risk assessment decisions.

Setup

setup the vibration magnitude of the power tool

The amount of vibration produced by the tool must be known. This is provided by the manufacturer or, especially with tools that vary considerably with different materials, can be measured using a Vibration Meter.

Set the m/s2 figure for the tool using the buttons on the front of the HAVi.

Attach to Tool

The HAVi is attached to the tool using the velcro strap or ties that are supplied in the kit. It needs to be firmly attached, but this is not as critical as when using a Vibration Meter - the HAVi detects the vibration of the tool but is not measuring it.

The HAVi can be moved between tools to follow the worker, or can be left attached to one tool to avoid having to re-enter the vibration magnitude figure.

Readings

The HAVi senses the tool operating. It starts and stops automatically, recording the length of time the tool is in use (trigger time), and calculating the total vibration exposure. This is displayed as HSE points.

The monitor also has a warning light that flashes amber when the Exposure Action Level (EAV = 100 points) is exceeded and red when the Exposure Limit Value (ELV = 400 points) is exceeded.

Intrinsically Safe HAVi

The intrinsically safe version of the HAVi vibration monitor is for use in hazardous and potentially explosive atmospheres. The intrinsically safe version is easily recognised by the yellow case.

The I.S. version works in exactly the same was as the standard HAVi and makes the same measurements and calculations.

The intrinsically safe vibration monitor is intended for:

  • Oil and gas industry
  • Petrochemical plants
  • Printing works
  • Other potentially explosive atmospheres

Order Codes

The I.S. HAVi is usually supplied as part of a HAVi Vibration Monitoring Kit. The order codes are HAVI-IS-Kx and the prices can be seen in the Ordering box above.

Vibration Monitoring Kits

The HAVi Vibration Monitor is usually supplied in a kit that includes 6, 12 or 24 monitors along with all necessary accessories.

Order Codes

The order codes for the intrinsically safe HAVi Kits are HAVI-IS-Kx, where x indicates the number of monitors included. For example, the HAVI-IS-K6 kit includes six I.S. approved monitors and accessories.
