What is the minimum duration that an emergency wash device should provide water?

The minimum duration that an emergency wash device should provide water is 15 minutes. This standard is essential because in the event of a chemical exposure, individuals need sufficient time to thoroughly rinse the affected areas, especially for hazardous substances that can cause serious injury. A 15-minute wash allows for the dilution and removal of chemicals from the skin or eyes, significantly reducing the risk of long-term effects.

The recommended duration aligns with guidelines from health and safety organizations which emphasize the importance of effective decontamination practices. This time frame ensures that users can adequately flush the area while allowing for a safer response during emergencies. The other options do not meet the established safety standards for adequate decontamination in critical situations, making them insufficient in ensuring the health and well-being of individuals exposed to harmful substances.
