Common Questions About Extension Cord Safety
Is it safe to use extension cord after the expiration date?
Extension Cord past its labeled date may still function but could have reduced effectiveness. The manufacturer's date indicates guaranteed performance. After this date, the product may separate, lose potency, or not perform as expected. Check for changes in color, consistency, or smell before use.
What if extension cord looks different than when purchased?
Changes in color, consistency, or separation in extension cord typically indicate the product has degraded. While this may not pose a safety hazard for non-food items, it usually means reduced effectiveness. If the product has solidified, separated significantly, or changed color dramatically, it is best to replace it.
