When you receive a LOLER Report of Thorough Examination, the defect categories determine what you need to do next. Misunderstanding these categories can lead to unsafe equipment remaining in use or unnecessary downtime. When you know how to interpret each category, you can take the right action at the right time.

What Are LOLER Defect Categories?

During a thorough examination, a competent person assesses lifting equipment and identifies any defects that could affect safety. These findings are grouped into categories based on risk and urgency.

The categories guide your response and help you prioritise corrective actions.

Defects That Require Immediate Action

This is the most serious category. These defects pose an immediate risk to safety.

If a report identifies a defect that requires immediate action:

• Stop using the equipment straight away
• Remove it from service or isolate it
• Arrange repairs or replacement before further use
• Do not return the equipment to service until it is confirmed safe

In many cases, the competent person will state that the equipment is not safe to use. Continuing to use it can lead to enforcement action and serious incidents.

Defects That Require Action Within a Specified Timeframe

These defects are not immediately dangerous but could become a risk if ignored.

The report will include a deadline for corrective action.

You should:

• Schedule repairs within the stated timeframe
• Monitor the condition if the equipment remains in use
• Ensure the issue does not worsen before repair
• Record when the defect is resolved

Failing to act within the timeframe can escalate the issue and create compliance risks.

Advisory Observations

Advisory observations highlight areas that are not yet defects but may require attention in the future.

These often relate to:

• Early signs of wear or deterioration
• Minor damage that does not yet affect safety
• Improvements to maintenance or storage practices

You should not ignore these observations. They often indicate where future defects may develop.

What Happens After a Serious Defect Is Found?

If a serious defect is identified, the competent person may have a legal duty to inform the enforcing authority.

This typically happens when:

• The equipment presents an immediate risk of serious personal injury
• The defect has not been addressed
• There is a risk of continued unsafe use

This is another reason why prompt action is essential.

How to Respond to LOLER Defects Effectively

A structured response helps you stay compliant and maintain safe operations.

For every defect:

• Log the issue clearly
• Assign responsibility for corrective action
• Set deadlines based on risk and report guidance
• Keep evidence of repairs and replacements
• Update your records and inspection history

Using Defect Data to Improve Safety

LOLER reports are not just compliance documents. They provide valuable insight into equipment condition and performance.

Look for patterns such as:

• Repeated failures on the same equipment
• Similar defects across multiple assets
• Issues linked to incorrect use or poor maintenance

When you act on these trends, you reduce future defects and improve overall safety.

Why Understanding LOLER Defect Categories Matters

Clear understanding of defect categories allows you to prioritise risk, protect your workforce, and avoid enforcement action.

When your team knows what each category means and how to respond, you create a safer and more controlled working environment.
