Fox 40 Whistle
Without a "pea" that will stick or swell when wet, this whistle works under almost all conditions, including under water. The Fox 40 has a reputation for being one of the loudest whistles made. Its plastic body will not rust or transfer cold like metal whistles. It can be attached to your PFD or Radio Chest Harness to keep the whistle close at hand, but out of the way.
Working-At-Height / Industrial Rope Access / Technical Rope Rescue
Working at height requires reliable, quality equipment. The Fox 40 Whistle can be used with confidence in work-at-height maneuvers for industrial rope access or technical rope rescue when used in accordance with the regulatory safety standards it falls under. Always use life safety equipment and gear according to the regulatory safety standards for which it is classified and/or certified.
