At Oberon, we emphasize that arc flash suits do not have a fixed expiration date. Instead, their service life depends on frequency of use, care, and workplace conditions. To ensure continued safety, we recommend:
- Pre- and Post-Use Inspections: Workers must check their suits before and after each use for damage, contamination, or signs of wear. Any suit showing compromised protection should be removed from service immediately.
- Formal Evaluations: Every 5 years at minimum, each suit should undergo a structured review to confirm it remains fit for service. This review is not a lifespan limit, but a best-practice interval for ensuring safety and considering technology upgrades.
⚠️ Important: The actual service life of a suit may be shorter than 5 years if it is heavily used, laundered improperly, or exposed to harsh workplace conditions.
Key Considerations for Suit Longevity
- Frequency of Use
- Daily use accelerates wear and may require earlier replacement.
- Light or occasional use can extend service life.
- Laundering Care
- Follow the laundering instructions in the User Guide (page 13).
- Avoid harsh detergents, bleach, or improper drying. Over-washing shortens garment life.
- Workplace Exposures
- Contact with chemicals, acids, or flammable contaminants may degrade protective properties.
- Suits exposed to such hazards should be closely inspected and may need early replacement.
- Storage Environment
- Store suits out of direct sunlight in a clean, dry environment (User Guide, page 12).
- Fabric Condition
- Oberon suits are made with aramid fibers, which may pill from abrasion.
- Replace any suit with more than 50% surface area pilled.
- Component Replacement
- Plastic components (hood lenses, adapters, etc.): replace within 5 years.
- Hard hat suspensions: replace annually.
Benefits of the 5-Year Review
Regular evaluations ensure workers benefit from the latest safety advancements, such as:
- The Oberon Escape Strap for worker rescue.
- Extended Leg Zippers for faster donning and doffing.
Summary
Arc flash suits are designed for long service life with proper care. Daily inspections keep workers safe on the job, while a formal 5-year review ensures long-term reliability and compliance. Lifespan may be significantly reduced by heavy use, harsh laundering, or damaging exposures. For detailed guidance, see the User Guide (pages 8–13).
