Safety Hearing Protection in Australia
Australian workplaces have strict rules to protect workers from loud noises that can hurt their hearing. This article explains those rules in a clear way and helps you pick the right earplugs or earmuffs to keep your ears safe on the job.
Understanding Noise Exposure Limits
The primary duty lies with the Person Conducting a Business or Undertaking (PCBU)—employers or those managing a workplace—to ensure noise levels stay within the stipulated exposure standards set by Safe Work Australia (SWA). Here’s a breakdown of the key limits:
Equivalent Continuous Noise Level (LAeq, 8h)
This is the average noise level over an eight-hour workday. The exposure standard is 85 decibels (dB(A)).
Peak Noise Level (LCpeak)
This refers to the highest sound pressure level measured during a workday. The exposure standard is 140 dB (C).
Why You Need Safety Hearing Protection
Loud noises at work can be sneaky. They might not always seem super bad, but over time they can really hurt your hearing. This damage is permanent, meaning once it’s done, you can’t fix it.
Safety hearing protection, like ear plugs or ear muffs, is like a shield for your ears. It brings down the volume of loud noises, so they don’t damage your hearing. This helps prevent hearing loss and that ringing in your ears some people get (tinnitus).
Choosing the Right Safety Hearing Protection
Australian Standard (AS/NZS) 1270:2002 dictates the standards for SHP. Here are some factors to consider when selecting the right equipment:
Noise Reduction Rating (NRR)
This number indicates the average amount of noise reduction provided by the protector. For instance, an NRR of 25 dB means the protector reduces noise levels by an average of 25 dB.
Types of Hearing Protection
There are two primary categories:
Ear Plugs
These insert directly into the ear canal and come in various materials like foam, silicone, and flanged.
Ear Muffs
These cup-like protectors fit entirely over the ears.
Comfort and Fit
Hearing protection should be comfortable to wear for extended periods. Opt for adjustable options for a snug fit.
Additional Considerations
Additional Considerations for Safety Hearing Protection:
Disposable vs Reusable
Disposable ear plugs are ideal for short-term or infrequent use, while reusable ear muffs offer a more cost-effective solution for long-term wear.
Communication Needs
Some workplaces require clear communication. Look for ear muffs with electronic features or disposable ear muffs that allow for conversations while attenuating noise.
Remember: The NRR rating is derived under controlled laboratory conditions. Real-world effectiveness can vary. When in doubt, opt for a higher NRR rating.
Shop for Safety Hearing Protection in Australia
Ensure you shop safety hearing protection from reputable suppliers who provide products compliant with AS/NZS 1270:2002 like the Hip Pocket Workwear and Safety online shop. When buying hearing protection equipment, look for details like NRR ratings and compliance certifications when making your selection.
Beyond Compliance: Hearing Conservation Programmes
Compliance with regulations is a must, but a proactive approach goes a long way. Consider implementing a hearing conservation programme that includes:
Keeping Track of Noise Levels
Regularly check how loud things are in your workplace.
Teaching Workers about Noise
Train your employees on how loud noise can hurt their hearing and how to wear and pick the right safety ear protection.
Hearing Check-Ups
Give your workers regular hearing tests to see if the noise is causing any problems early on.
By doing these things and focusing on quieting down the noise whenever possible, you can protect your workers’ hearing and make the workplace safer.
Conclusion
Protecting your hearing is vital. By understanding the noise regulations and choosing the right safety hearing protection, you can safeguard your ears and prevent hearing loss. Remember, your employer also plays a role – they should monitor noise levels, provide training, and offer hearing check-ups. By working together, you can create a safer and quieter work environment for everyone.
FAQs
How loud is too loud at work?
In Australia, the average noise level over an eight-hour workday shouldn’t go above 85 decibels (dB(A)).
What kind of hearing protection should I use?
There are two main types: ear plugs and ear muffs. Choose the one that’s most comfortable for you and that reduces noise enough for your workplace environment. Consider the Noise Reduction Rating (NRR) when selecting – a higher NRR means more noise reduction.
Do I need to get my hearing checked?
If you work in a noisy environment, it’s a good idea to get regular hearing tests to check for any damage. Your employer might even offer these as part of a hearing conservation programme.
