===== Safety Concerns =====

This tool makes use of a heated solvent! A lab coat, face shield, and nitrile gloves must be wore by the user whenever the SCA 1200 HT is to be opened to protect from solution and vapor fumes. In case of contact with solution flush eyes, and skin with water, remove all contaminated clothing, and get medical attention immediately.
