Detailed Answer
IP67 (Lideral LD series) protects against 1m/30min immersion — recovered within 30 minutes after falling into water, still normal; IP68 (Xingjia optional) protects against continuous immersion (1.5m+). Port operations have falling-into-water risk (loading/unloading ships); select IP67 or above + lanyard to prevent falling. After falling into water: retrieve, power off, dry, test.
