How Hot It Is A quality pepper spray can protect you from intruders or attackers.
Quality is the key, however.
Some products on the market won't even deter a dog, reporter Wendy Bell reports. There are products in stores and retail outlets that clearly say on the can that they contain food-grade pepper spray. Others fail to provide ingredients, an expiration date or instructions. Self-defense expert Barbara Gooderham said that consumers need to know what is in a spray, or how hot it is, before purchasing. The heat of a spray is determined by Scoville heat units.
