HAVS Monitoring Sheet: What to Record and How to Keep Exposure Records HSE-Ready

When an HSE inspector asks to see your HAVS records, a spreadsheet with shift times and tool names doesn't cut it. What they want to see is daily exposure data — the tool, the magnitude, the trigger time, and the resulting exposure calculation — for each worker using vibrating tools. That's what a HAVS monitoring sheet is, and it's the document most small contractors either don't have or can't produce quickly.

This guide covers exactly what your monitoring sheet needs to contain, how to format it, what the regulations require you to keep, and for how long.

What a HAVS Monitoring Sheet Is (and Isn't)

A HAVS monitoring sheet is a daily record of individual vibration exposure. It tracks which tools a worker used, how long they used them, the vibration magnitude of each tool, and the resulting daily exposure figure — usually expressed in m/s² A(8) or in the HSE's exposure points system.

It is not:

• A risk assessment (that's a separate document covering tool types, work patterns, and control measures)
• A health surveillance record (those are maintained by your occupational health provider and are confidential)
• A toolbox talk attendance sheet

The monitoring sheet is the operational record. It's what you produce when someone asks "what was this worker exposed to on Tuesday?" Without it, you can't answer — and the risk assessment alone doesn't demonstrate what actually happened on site.

The Four Fields Every Daily Record Needs

Whether you use a paper sheet, a spreadsheet, or a digital log, every daily record should contain four things per worker, per tool used:

What to record	Why it matters	Example
Tool used	Identifies the vibration source — each tool has a different declared magnitude	Pneumatic breaker
Vibration magnitude (m/s²)	The declared value from the tool data sheet or HSE database	18 m/s²
Trigger time (minutes)	Hands-on time running the tool — not shift time, not task time	35 minutes
Exposure points (or A(8))	The calculated exposure figure for that tool on that day	378 points

The total daily exposure across all tools used — the sum of all tool contributions — is what you compare against the EAV (100 points / 2.5 m/s² A(8)) and ELV (400 points / 5 m/s² A(8)).

HSE guidance confirms that "results must be in m/s² A(8) or 'exposure points' so you can make valid comparisons with the Exposure Action and Limit Values." A raw log of trigger times without a calculated exposure figure isn't a monitoring record — it's notes.

Getting the Vibration Magnitude Right

The figure you record for tool vibration magnitude should come from the tool manufacturer's data sheet — the vibration emission declared under the Supply of Machinery (Safety) Regulations. This is stated in the tool handbook or available from the manufacturer on request.

Where you don't have the manufacturer's figure to hand, the HAVS trigger time chart provides typical ranges for common tool categories. Use this for planning and quick reference; where HSE asks for evidence, the manufacturer's declared value carries more weight.

Don't record the same magnitude for every tool. A 4" angle grinder runs at a different vibration level than a 9" angle grinder. A well-maintained breaker will typically have a lower measured output than one with a worn chisel. The monitor sheet is only as accurate as the magnitudes you put in it.

Trigger Time: The Number People Get Wrong

Trigger time is the time a worker's hand is on the running tool — not the time they spend on a task, not the shift length. This is where most manual records err.

A groundworker breaking out a concrete footing might be on a breaker for 90 minutes across the morning, with tool-down time between cuts, waiting for the crane, and tea breaks. The shift runs 7 hours. The trigger time is 90 minutes — that's what goes on the monitoring sheet.

Accurate trigger time is also what separates a record that protects you from one that doesn't. If your sheet shows 4 hours of breaker use and the breaker's magnitude is 20 m/s², you're recording an ELV breach for every row. If the actual trigger time was 45 minutes, the record should show that — with the crew member who confirmed it.

For a practical approach to capturing trigger time on a live site, see our HAVS records guide which covers logging methods that work on busy sites.

Daily vs Periodic Monitoring: What HSE Expects

There is no legal requirement to record daily exposure for every worker on every day. The HSE is explicit: "Monitoring hand-arm vibration exposure all the time is probably not a good use of resources." What the regulations require — under Regulation 5 of the Control of Vibration at Work Regulations 2005 — is that the risk assessment records the significant findings, including an estimate of worker exposure levels.

In practice, this means:

• For workers whose daily exposure is variable (different tools, different durations), periodic spot-monitoring gives you the data to populate the risk assessment with realistic exposure estimates
• For workers whose daily exposure is predictable (the same task, same tool, similar durations each day), a baseline measurement plus regular confirmation is sufficient
• Where a worker is approaching or has exceeded the EAV, more frequent monitoring is justified

The use case for a daily monitoring sheet is precisely the variable-exposure worker — the one who might be on a breaker for 30 minutes one day and 3 hours the next, or who switches between grinder, drill, and breaker across the week. For them, a daily record is how you actually know what they were exposed to.

The HAVS exposure calculator makes the daily calculation straightforward: enter the tools and trigger times, and it returns the daily exposure in both points and A(8).

What Specific Fields to Include on the Sheet

A functional HAVS monitoring sheet for a small contractor should include:

Header (per shift):

• Site name and date
• Supervisor/recorder name
• Weather conditions (relevant where cold worsens symptoms — a contextual flag)

Per worker row:

• Worker name or identifier
• Tool 1: name, magnitude (m/s²), trigger time (minutes), exposure points
• Tool 2: name, magnitude, trigger time, points (repeat for each tool used)
• Daily total exposure points
• EAV reached? (yes/no)
• ELV reached? (yes/no)
• Any symptoms reported (yes/no — if yes, escalate per health surveillance procedure)

Footer:

• Recorder signature
• Date totalled

The symptom flag is worth including even though it's technically a health surveillance input. Catching "yes" on a Monday morning before the week begins is the cheapest health surveillance there is.

The HAVS Log Sheet Template generates a print-ready version of this format — pre-formatted with the calculation structure so only names, magnitudes, and trigger times need to be filled in on site.

How Long to Keep the Records

Regulation 7 of the Control of Vibration at Work Regulations 2005 requires that a health record for each employee under health surveillance "is made and maintained and that the record or a copy thereof is kept available in a suitable form" — but it does not specify a retention period. HSE's general health surveillance record-keeping guidance states that where the regulations do not set a period, "the health record should be kept at least while you employ the worker." In practice, HAVS health records held by occupational health providers are often retained for much longer — 40 years is the benchmark set under the COSHH Regulations and is widely applied to vibration health records too, reflecting the long latency of vibration-related disease.

For the operational monitoring sheet (not the clinical health record), good practice is to keep it for as long as it evidences compliance with the Regulations. In practice, most employers retain HAVS monitoring sheets for at least 5 years, alongside the risk assessment and control records.

Keep the monitoring sheet, the risk assessment, the health surveillance summaries, and the training records in the same HAVS register — that's what an HSE inspector works through, and having it in one place reduces the friction of producing it on demand.

What Makes a Record HSE-Inspection-Ready

An HSE inspector reviewing your HAVS records looks for evidence that:

1. You know which workers are exposed and at what level (monitoring sheet)
2. You've assessed the risk systematically (risk assessment)
3. You've taken action when exposure approached or exceeded the EAV (control records)
4. Workers have received health surveillance (health records from OH provider)
5. Workers have received information and training (training records)

A monitoring sheet full of raw trigger times without the exposure calculation fails the first test — the inspector can't immediately see whether the EAV was reached. A monitoring sheet with calculated points, the EAV/ELV column, and a symptom flag answers everything they need to know on the first read.
