Incident Energy Analysis. A component of an arc flash hazard analysis used to predict the incident energy of an arc flash risk assessment for a specified set of conditions. An incident energy analysis is an important part of performing the arc flash hazard analysis for a specific task and item of electrical equipment.
Tilling hydrated lime into bare soil effectively raises pH levels. Except for acid-loving plants like camellias (Camellia spp.), which grow in U.S. Department of Agriculture plant hardiness zones 6 through 10, depending on species, garden and lawn soils should have a soil acidity or pH of between 6.0 and 6.5.
Test your soil's pH level to determine if lime is needed. A pH test measures the soil's alkalinity or acidity. When the pH is above 7.0, the soil is said to be alkaline; when below 7.0, it is acidic. A pH level of 6 to 7 is ideal for most grasses. If your soil is too acidic, use a lime application.1  Bring a soil sample to a government or independent soil testing laboratory for the most complete testing results. 2  You can use a self-test kit or pH probe, sold at garden centers, to test your soil.
