National Hearing Protection Month 2025: Why Hearing Safety Warnings Matter
October marks National Hearing Protection Month, a critical time to raise awareness about hearing loss prevention in the workplace. Every year, thousands of workers are exposed to noise levels that can cause permanent hearing damage, often without realizing the risk. Effective hearing protection requires more than just personal protective equipment—it starts with clear, standards-based warnings that alert employees to potential hazards.
At Clarion Safety, we help employers communicate risk effectively through ANSI and ISO-compliant safety labels and signs, ensuring workers recognize when and where hearing protection is required.
Why Hearing Protection Is Critical in the Workplace
High-Risk Industries for Hearing Loss
Workplace hearing loss is one of the most common occupational illnesses. According to OSHA and NIOSH, prolonged exposure to noise above 85 decibels can permanently damage hearing. Industries like manufacturing, construction, mining, and agriculture often expose workers to high-decibel environments where hearing damage can occur gradually, often going unnoticed until it’s too late.
- Manufacturing: Machinery and production lines generate consistent noise levels above recommended limits.
- Construction: Heavy equipment, drills, and saws create high-decibel exposure.
- Mining: Drilling and blasting produce extreme noise hazards.
- Aviation and Transportation: Aircraft engines, turbines, and transport vehicles expose workers to intense sound levels.
In each of these environments, workers rely on clear warnings to know when hearing protection is required.
The Role of OSHA and ANSI Standards in Hearing Protection
OSHA’s Occupational Noise Exposure Standard (29 CFR 1910.95) mandates that employers implement hearing conservation programs when noise levels exceed 85 dB. Compliance is easier when hazard communication is standardized and visible.
The ANSI Z535 standards provide a framework for effective safety signage and labeling. For hearing hazards, these standards ensure that:
- Colors and symbols are instantly recognizable.
- Labels and signs communicate urgency and required action.
- Information is consistent across industries and workplaces.
Globally, the ISO 7010 symbol library and ISO 3864 standards further ensure that hearing protection symbols are universally understood, making it easier for companies with multilingual workforces to maintain compliance and safety. Clarion Safety’s leadership in these standards means we design products that meet both U.S. and international requirements.
How Safety Warnings Support Hearing Conservation
Clear warnings are a first line of defense in preventing hearing loss. Clarion Safety’s labels and signs help reinforce hearing protection practices:
- Mandatory Hearing Protection Signs: Placed at entrances to high-noise areas to alert employees immediately.
- Noise Hazard Labels for Machinery: Remind operators and maintenance teams to wear hearing protection while working on or near equipment.
These warnings aren’t just regulatory checkboxes—they actively improve safety awareness, reduce incidents, and protect employers from liability.
Key Features of Clarion Safety Hearing Protection Labels

- Made with durable materials to withstand industrial environments.
- Incorporate globally recognized symbols, supporting multilingual workplaces and international compliance.
Best Practices for Employers During Hearing Protection Month
National Hearing Protection Month is an opportunity to refresh and reinforce hearing safety programs. Employers should:
- Conduct noise hazard assessments to identify areas where hearing protection is necessary.
- Implement proper PPE and signage in all high-noise areas.
- Train employees to recognize and respond to hearing hazard warnings.
- Regularly update and maintain safety labels to ensure visibility and compliance.
By combining effective warnings with proactive hearing conservation programs, employers can significantly reduce the risk of workplace hearing loss.
