Hard Hat Safety and Requirements
The Problem
Head injuries are among the most serious and potentially fatal injuries that can occur on a worksite. Whether caused by falling objects, overhead equipment, or electrical hazards, many of these incidents are preventable with one simple piece of personal protective equipment: a properly fitted safety helmet. Failing to wear a safety helmet—or using a damaged or unsuitable one—puts workers at significant risk. Today, we’ll cover when helmets are required, how to choose the right one, and how to maintain them in accordance with WorkSafe New Zealand expectations.
Identify the Hazards
- Falling Objects: Tools, materials, or debris falling from scaffolding, ladders, or platforms above.
- Overhead Equipment: Items falling from conveyors, elevated machinery, or mobile plant.
- Electrical Hazards: Working near live electrical components or overhead power lines.
- Unforeseen Hazards: Working near roof edges, within trenches, or under overhead activities where tools and materials may fall.
Safety Practices and Preventative Measures
1. When Are Safety Helmets Required?
You must wear a safety helmet when there is a risk of:
- Being struck on the head by a falling object
- Your head making contact with fixed objects
- Exposure to electrical hazards
Examples of high-risk areas:
- Beneath scaffolding or elevated work platforms
- Around co-workers using tools or equipment overhead
- In trenches or excavations where materials may fall
- Around live electrical services or under power lines
Why it matters: A compliant, well-maintained safety helmet can mean the difference between walking away and suffering a life-altering injury.
Real-Life Case or Scenario
On a recent site, a worker narrowly avoided a serious head injury when a wrench fell from approximately six metres. Fortunately, they were wearing a compliant, well-maintained safety helmet. The helmet absorbed the impact and prevented major injury. This event highlights how quickly an accident can occur—and how safety helmets can save lives.
Employee Responsibilities
- Wear a safety helmet at all times in designated areas or where there is any risk of head injury
- Inspect your helmet daily for cracks, UV degradation, or signs of damage
- Replace your helmet if it has received an impact, even if there is no visible damage
- Report any unsafe work practices or damaged equipment immediately
Employer Responsibilities
- Provide compliant safety helmets that meet AS/NZS 1801 standards
- Ensure helmets are regularly inspected and replaced when damaged or expired
- Train workers on correct use, fit, and storage of helmets
- Make sure helmet use is enforced in all relevant work areas
Discussion & Questions
- "Where on this site do you think safety helmets are most critical?"
- "Have you seen any situations where someone wasn't wearing a helmet in a high-risk area?"
- "Do you know how to check your helmet for damage or expiry?"
Encourage workers to share their input and observations.
Commitment/Action Plan
Let’s commit to wearing our helmets correctly and inspecting them daily. If you notice someone working without a helmet, speak up. Safety is everyone’s responsibility, and your actions could prevent a serious injury.
Wrap-Up
Your safety helmet protects your most valuable asset—your brain. Wearing it properly, checking it regularly, and speaking up when something’s not right will help ensure everyone goes home safely. Thank you for doing your part to protect your mates and yourself.
