Episode 16| In this episode of Let's Talk Safety, Rani Naidoo, Senior Application Engineer and Regulatory Manager for 3M South Africa, delves into the importance of respiratory protection standards. The discussion emphasizes how standards such as EN 149 and EN 140 ensure fit-for-purpose safety in the workplace. Rani highlights the challenges of selecting appropriate respiratory protection, the role of homologation in adapting international standards to local requirements, and lessons learned from real-world incidents that underscore the criticality of adhering to standards.
Key Points:
- Importance of Standards in Respiratory Protection
- EN 149 focuses on disposable respirators, including the 2009 amendment (EN 149+A1), which added Dolomite dust testing.
- EN 140 covers reusable respirators, including fit, maintenance, and disposal criteria.
- Understanding Homologation
- Homologation ensures international products meet local standards for safety and effectiveness.
- Examples include the adaptation of EN standards for South Africa's regulations.
- Challenges in Selecting Respiratory Protection
- Many users rely on default recommendations without understanding the standards behind FFP1, FFP2, and FFP3 masks.
- Workers often lack knowledge about change-out schedules for disposable and reusable respirators.
- Lessons from the Philips Lawsuit
- The case highlights the devastating impact of non-compliance with safety standards. Over 500 deaths and 85,000 claims resulted from harmful particles released by faulty equipment.
- Specific Workplace Hazards
- Welding tasks require respirators with FFP2 filters and carbon layers to protect against carcinogenic fumes and ozone exposure.
- Reusable respirators must be assessed for compatibility with chemicals and particles.
- Simplifying Compliance
- Partner with reputable suppliers and verify products through certifications such as BSI or homologation certificates.
- Use government or regulatory databases to confirm product approvals.
- Testing Criteria for Standards
- Respirators are tested for filtration efficiency, durability, strap strength, and material compatibility.
- Specific tests include resistance to collapse, breathability, and leakage prevention.
This interview provides valuable insights for safety and procurement managers, emphasizing the importance of informed decisions in respiratory protection.
