Human Factors Evaluation of the Safety Sea Systems Helmax Helmet in the Open-Circuit Mode.

Abstract

A preliminary human factors evaluation of the Safety Sea Systems Helmax multipurpose diving helmet was conducted in the unmanned (dry) and manned (wet) modes. A bench evaluation of the helmet revealed several minor discrepancies revolving around the adaptability of helmet components to varying diver anthropometry. The visual field afforded the diver wearing the Helmax is somewhat restricted but comparable to U.S. Navy MK 12 as assessed by underwater visual perimetry. However, divers wearing the Helmax during open-circuit test pool dives rated the Helmax adequate or better in the areas of comfort, fit, breathing resistance, communications and ease of operation. No major problems were documented in the area of diver safety while wearing the Helmax helmet during this limited evaluation.
