T-butyl alcohol is flammable and an irritant so spilling it on his hands and bench may cause a fire hazard and cause irritation to his hands or eyes.
A tertiary aliphatic alcohol called t-Butyl Alcohol (t-BuOH) is employed in cosmetics as a perfume carrier, alcohol denaturant, and solvent. In 32 different eye makeup, fragrance, and shaving preparation formulations, t-BuOH was listed as an ingredient with amounts between 0.00001% and 0.3%. The acute oral LD(50) in rats was 3.0 to 3.7 g/kg, demonstrating the low acute oral toxicity in animals. Although weight loss was observed and microscopic damage to the liver and kidney, as well as alterations like centrilobular necrosis, vacuolation in hepatocytes, and loss of hepatic architecture, were noted in short-term oral studies in rats, t-BuOH at 2% (w/v) or less in drinking water did not cause gross organ or tissue damage in mice.
