now about calories. In the world of PPE, calories are used to define the protection level of a material, garment or system of materials/garments. But what is a calorie? And how can the calorie system help you enhance your safety when working in a high-risk environment? Why calories? When an electric arc is triggered, different types of energy or risk factors are created, such as arc power, arc energy and incident energy, all of which are measured in calories. This is why calories per square centimeter (cal/cm2 become the unit used to measure a material or product’s level of protection. What is a calorie? A calorie is the amount of energy needed to increase the temperature of one gram of water by one degree Celsius, or to be precise, to increase the temperature of one gram of water from 14.5 to 15.5 degrees Celsius under standard atmospheric pressure of 1013 hPa. Make sure your whole outfit offers adequate protection Based on various tests and reports and our years of experience, we recommend that you should never wear garments that offer total protection of less than 11 calories/cm2 This calorie level does not in any way provide total protection, far from it, but should be seen as a minimum level. Different jobs require different levels of protection, and the higher the calorie level your clothes (or outfit) have, the better protection you get. Be sure you know the risk level before you enter a specific risk environment, and wear appropriate clothing. ) has if you are going to work in or near a high-risk environment.
