Q. Is nichrome wire safe to use?

Never touch a nichrome wire while electricity is being supplied; it is not safe. According to the Globally Harmonized System (GHS) categories for the Hazard Communication Standard this chemical poses no threat to human health or the environment. Be careful with any and all substances in the lab. While there is no reason to believe that this item is dangerous it is important to note that chemical reactions are never completely predicted. That is if a 120-volt control is adjusted to 50% the resulting 60-volt output is calculated as follows: 120 x.50 (50%). If a 120-volt control is turned down to 30% the resulting 36-volt output will be calculated as 120 x.30 (30%).
