HAVS Course Summary: Key Points and Safety Essentials

This summary highlights the key points from the Hand-Arm Vibration Syndrome (HAVS) Awareness Course, helping reinforce the most important safety messages.

What Is HAVS?

Hand-arm vibration syndrome (HAVS) is a serious but entirely preventable condition caused by regular exposure to vibration from handheld tools.

Common tools that can cause HAVS include:

• Grinders
• Drills
• Breakers
• Chainsaws
• Other handheld vibrating equipment

Over time, vibration can damage the nerves, blood vessels and joints in the hands and arms.

Once this damage becomes permanent, it cannot be reversed.

Recognising the Symptoms

Early symptoms of HAVS include:

• Tingling or pins and needles
• Numbness
• Pain in the hands or arms
• Reduced grip strength
• Vibration white finger in cold conditions

These symptoms must never be ignored.

Early reporting is essential, as action taken at an early stage can prevent the condition from worsening.

Legal Responsibilities

UK law requires employers to:

• Assess vibration exposure risks
• Reduce exposure as far as reasonably practicable
• Provide health surveillance

Employees must:

• Use equipment safely
• Follow control measures
• Report symptoms as soon as they appear

Both employers and employees play a vital role in preventing HAVS.

How to Reduce the Risk of HAVS

You can significantly reduce your risk by following simple safety measures:

• Choose low-vibration tools
• Keep equipment well maintained
• Limit time spent using vibrating tools
• Use correct techniques and avoid excessive force
• Keep your hands warm

Small changes in working practices can make a big difference.

Understanding Exposure Limits

The Exposure Action Value (EAV) and Exposure Limit Value (ELV) are used to monitor and control vibration exposure.

• EAV – the level where action must be taken
• ELV – the maximum limit that must never be exceeded

Understanding these values helps you stay within safe exposure limits.

The Role of Health Surveillance

Health surveillance is essential for detecting early signs of HAVS.

• Regular checks help identify symptoms early
• Early action can prevent permanent damage
• Honest reporting supports effective protection

Health surveillance protects your long-term health and ability to work safely.

Final Key Messages

• HAVS is preventable
• Symptoms must be reported early
• Exposure must be controlled
• Everyone has a responsibility for safety

By understanding the risks and following safe practices, you can protect yourself and others from long-term harm.
