||The results of tests conducted on foot protectors capable of ensuring protection against very high pressure (VHP) water jets are presented. The test procedure adopted involved passing a foot protector at a speed of 0.5 m/s in front of a VHP water jet. The distance between the protector and the water jet nozzle was 10 cm. The perforation detection system comprised a 0.18 mm thick latex sheet, which covered the artificial foot. The latex sheet and artificial foot were inserted inside the boot to be tested. Boots were tested by using various types of jets (straight, rotating, flat, orbital). Four boot models commonly used by operators were tested. Results showed that normal leather and rubber boots should be prohibited, that woodcutter type boots can only be used for flat jets up to a pressure of 1,050 bar, and that only boots claiming protection against VHP water jets truly protect against all types of jets for a pressure up to 1,150 bars and a jet flow of 35 L/min.
