When chemicals come into contact with skin or eyes, the duration of exposure plays a critical role in the potential for injury. The longer hazardous substances remain in contact, the greater the likelihood that they will penetrate tissues and cause damage. Immediate removal and decontamination are vital in minimizing harmful effects.

For instance, in the case of corrosive chemicals, prolonged exposure can result in deep tissue burns, irritation, or permanent damage to the skin or eyes. The effectiveness of safety measures like eyewashes or emergency showers diminishes the longer the harmful substance remains. This emphasizes the importance of quick action in emergency situations to minimize injuries and the necessity of properly trained personnel to manage these incidents. Hence, the assertion that more harm can occur due to extended exposure is supported by the understanding of how harmful substances operate on biological tissues.
