ABSTRACT
Products used around fluids or in wet environments should be designed to prevent water ingress, ensuring they remain operable and safe. An electrical device might pose a shock hazard if it gets wet, or at least short-circuit and become inoperative, which by itself could pose a hazard. The obvious solution is waterproofing, or at least designing a product to be relatively invulnerable to fluid ingress. There are plenty of standards for what constitutes being waterproof and water resistant. Water-resistant products might use mechanical means to protect against downpours or splashes, such as those created by Mother Nature or people who spill their soft drink. Products face an increasing waterproofing challenge as water pressure increases exponentially with depth. Accordingly, manufacturers often claim waterproofness only to a specified depth. In addition to making products waterproof and water resistant, it might be necessary to advise users in instructions for use, by means of a warning label, to avoid exposure to water and moisture.
