You can usually check the specifications of your devices on the manufacturer’s or retailer’s website. Ratings appear as two numerals, the first measuring protection against solid objects on a scale from 0 (no protection) to 6 (no ingress of dust). The second numeral rates the enclosure’s protection against liquids and uses a scale from 0 (no protection) to 9 (high-pressure hot water from different angles). 

If your device carries an IP67 rating, it is supposedly protected up to 1 meter (3.28 feet) of water for about 30 minutes. The 6 indicates such devices are protected against dust.
