Aluminum strips are generally safe to use, but there are a few safety concerns to consider. They can be sharp and cause cuts if handled improperly. Additionally, aluminum dust, if inhaled, can cause respiratory issues. It's important to handle aluminum strips with care, wear protective gloves, and avoid inhaling dust. In the case of electrical applications, ensure that aluminum strips are properly insulated to prevent electrical shocks. Always follow safety guidelines and manufacturer instructions when using aluminum strips.
