Interesting Facts About LOLER, PUWER & PSSR Inspections

When people think about workplace inspections, they often imagine clipboards, checklists, and red tags. But behind LOLER, PUWER, and PSSR inspections lies a fascinating world of engineering, history, and real-life safety lessons. Here are some interesting facts that show why these inspections matter more than many people realise.

LOLER, PUWER & PSSR facts

1. LOLER Was Born From Serious Lifting Accidents

The Lifting Operations and Lifting Equipment Regulations (LOLER) came into force in 1998, largely due to a long history of accidents involving cranes, hoists, and lifting accessories.

Interesting fact: Many early lifting failures weren’t caused by overloading — they were caused by small defects, such as worn pins or stretched chains, that went unnoticed over time.

Today, LOLER inspections focus on spotting these minor defects before they become major failures.

2. Chains and Slings Stretch Before They Break

Under LOLER, lifting accessories like chains and slings must be examined regularly.

Interesting fact: Steel chains don’t usually snap without warning. They slowly elongate under load. Measuring this stretch during inspection is one of the most reliable ways to predict failure before it happens.

That’s why precise measurement is a critical part of a thorough LOLER examination.

3. PUWER Applies to More Than You Think

The Provision and Use of Work Equipment Regulations (PUWER) cover almost any equipment used at work — from large industrial machinery to hand tools.

Interesting fact: Something as simple as a ladder or bench grinder can fall under PUWER. If it’s used for work, it must be suitable, maintained, and safe.

PUWER is less about paperwork and more about day-to-day safe use.

4. Missing Guards Are One of the Most Common PUWER Failures

During PUWER inspections, one of the most frequent issues found is missing or inadequate guarding.

Interesting fact: Many guards are removed temporarily for maintenance and never refitted. Statistics show that rotating parts — such as belts, pulleys, and shafts — are responsible for a large number of serious injuries.

A properly fitted guard can be the difference between a near-miss and a life-changing accident.

5. Pressure Systems Can Store Enormous Energy

The Pressure Systems Safety Regulations (PSSR) apply to systems containing steam, gases, or fluids under pressure.

Interesting fact: Compressed air systems can store energy comparable to explosives. When a pressure vessel fails, it doesn’t just leak — it can rupture violently.

That’s why PSSR inspections focus heavily on deterioration, corrosion, and safe operating limits.

6. Corrosion Often Starts Where You Can’t See It

Under PSSR, internal condition is just as important as external appearance.

Interesting fact: Many pressure vessels fail from the inside out. Moisture, contaminants, and poor drainage can cause internal corrosion long before any external damage is visible.

A system can look perfectly fine on the outside and still be dangerously weakened internally.

7. Written Schemes of Examination Are Legal Documents

For PSSR, a Written Scheme of Examination (WSE) is required.

Interesting fact: A WSE isn’t just guidance — it’s a legally enforceable document. Operating outside its limits or inspection intervals can invalidate insurance and place responsibility firmly on the duty holder.

This makes accuracy and clarity in written schemes essential.

8. Inspections Protect More Than People

While safety is the top priority, inspections also protect businesses.

Interesting fact: Regular LOLER, PUWER, and PSSR inspections often extend equipment lifespan. Catching wear early prevents catastrophic failures that can destroy machinery, halt production, and lead to costly downtime.

In many cases, inspections save far more money than they cost.

9. Most Serious Accidents Are Preventable

Across LOLER, PUWER, and PSSR, investigations repeatedly show the same trend.

Interesting fact: The majority of serious incidents are not caused by freak accidents — they are caused by known defects, overdue inspections, or ignored recommendations.

Routine inspections turn known risks into managed risks.

10. Compliance Is About Confidence

At its core, inspection compliance isn’t just about ticking boxes.

Interesting fact: Businesses that maintain strong inspection regimes often report higher staff confidence and better safety culture. When employees trust their equipment, they work more efficiently and with fewer incidents.

Final Thoughts

LOLER, PUWER, and PSSR inspections are far more than regulatory requirements. They are built on engineering principles, hard-earned lessons, and decades of real-world experience.

By understanding the why behind inspections — not just the what — businesses can create safer, more reliable, and more productive workplaces.
