Operator Safety

Each SAL is expressed using scientific notation (10-n). A low-level sterilization process may achieve an SAL of 10⁻³, indicating that there is a one in 1,000 chance of a microorganism surviving. High-level sterilization for heat-resistant medical instruments may achieve a rating of 10⁻⁴ or a one in 10,000 chance of microorganism survival. An SAL of 10⁻⁶ is the industry standard of sterility devices entering areas of the body (excluding the digestive tract), representing a microorganism survival probability of one in 1,000,000.
