Hand-Arm Vibration Safety Instruction

Educational guidance on how workplace induction and safety instruction generally work — connected to workplace safety, occupations, industries, employment documents and company types. Informational only — not certified training, not an official qualification and not a substitute for mandatory workplace instruction; employers remain responsible for required training, competence and authorisation.

What this instruction covers

This page outlines, in general educational terms, the safety information around hand-arm vibration (HAV) — how vibrating tools can harm health over time, how exposure is meant to be limited, and the checks and surveillance involved.

It is awareness material, not training. The employer must assess each person’s vibration exposure and provide task-specific instruction and health surveillance; this page does not deliver or replace that.

The hazards

• Regular use of vibrating tools can cause hand-arm vibration syndrome (HAVS), with damage to nerves, blood vessels and joints.
• Early signs include tingling, numbness and fingers turning white in the cold (vibration white finger).
• The damage builds up gradually and, once established, can be permanent.
• Both the vibration level of the tool and how long it is used each day — the “trigger time” — drive the risk.

Who needs it

• Workers who regularly use powered hand tools, grinders, breakers, sanders or similar.
• Groundworkers, fabricators, joiners and maintenance staff among others.
• Supervisors who plan tasks and manage trigger time across the day.
• New starters before they are set to work with vibrating tools.

The safe system of work

• Use the right tool for the job and keep it well maintained and sharp, as blunt or worn tools vibrate more.
• Limit “trigger time” — the time the tool is actually vibrating — and rotate tasks or share work to spread exposure.
• Let the tool do the work with a light grip rather than forcing it, and take regular breaks from vibrating tasks.
• Keep hands warm and dry, since cold reduces blood flow and worsens the effect of vibration.

Required PPE & controls

• Lower-vibration tools selected by the employer, kept maintained and used with correct consumables.
• Anti-vibration gloves can help keep hands warm but are not a reliable way to reduce vibration on their own.
• Warm, dry working conditions and warm-up breaks where work is in the cold.
• The exposure controls drawn from the employer’s vibration assessment.

Pre-use & pre-task checks

• Check the tool is maintained, sharp and not worn, as condition affects vibration.
• Check the right consumable, disc or bit is fitted for the material.
• Consider how long the task will run and whether trigger time can be reduced.
• Do not use a tool that is faulty, blunt or producing unusual vibration — report it.

What the worker is and is not authorised to do

• Use the tools and methods you have been instructed and authorised to use.
• Do not exceed the trigger-time limits set by your employer’s assessment.
• Do not modify a tool or remove anti-vibration features.
• How exposure is controlled and limited is set by the employer, not by this page.

What to do if something is wrong / reporting

• Report early symptoms — tingling, numbness or whitening fingers — promptly rather than working through them.
• Report tools that vibrate excessively, are blunt or are poorly maintained.
• Report tasks where trigger time cannot realistically be kept within limits.
• Follow the site’s reporting route so exposure can be reassessed and reduced.

Training & competence

Where workers are exposed to vibration, employers are generally expected to provide information and instruction on the risk, on how to use tools to reduce it, and on recognising and reporting early symptoms — and to provide health surveillance for those at risk.

Instruction such as this page is information, not competence. Reading it does not make anyone competent or replace the exposure assessment, task-specific instruction and health surveillance the employer must arrange.

Documentation

• The vibration exposure assessment for the tools and tasks.
• Records of instruction and information given to workers.
• Health surveillance records held confidentially by the employer.
• A record documents what was provided; it is not, by itself, proof of competence.

Common mistakes

• Treating anti-vibration gloves as a complete control for vibration.
• Ignoring trigger time and running vibrating tools far longer than assessed.
• Using blunt, worn or faulty tools that vibrate more than they should.
• Working through early HAVS symptoms instead of reporting them.

Who is responsible

The employer is responsible for assessing vibration exposure, reducing it so far as is reasonably practicable, providing suitable tools and instruction, arranging health surveillance and keeping records. This page is an educational outline only.

It does not deliver training, satisfy any legal requirement, or transfer the employer’s responsibility for controlling vibration exposure.
