Sterilization equipment is typically set to a temperature of 250°F (121°C) because this temperature is optimal for effective sterilization using steam. At this temperature, steam under pressure can achieve the necessary conditions to kill bacteria, viruses, and spores. This process, known as autoclaving, is widely used in barbershops and salons to ensure that all tools and implements are free of harmful microorganisms.

When using this method, the 250°F temperature is maintained for a specific period to ensure thorough sterilization. This level of heat is effective in penetrating materials, allowing for a comprehensive sterilization of items that are used in barbering, such as scissors and clippers. Temperatures lower than this may not effectively kill all pathogens, while higher temperatures, although they may also effectively sterilize, are not typically required in standard practices and could potentially damage certain tools or equipment.
