RESUMO

A principle structural component of helicopters is 2024-T3 aluminum alloy. This alloy has been designed for use in areas requiring high strength-to-weight ratios, but it is susceptible to corrosion damage. The air medical helicopter is frequently exposed to bloodborne pathogens, dirt, intravenous solutions and a variety of other contaminants. The amount of damage to the helicopter that can be caused by the use of cleaners and disinfectants has been raised as an area of concern for the safety of the helicopter, crew and patients. In a controlled study, 2024-T3 alclad aluminum strips were placed in 120-ml glass jars that were filled with 60 ml of solution and then sealed. The solutions used were disinfectants, cleaners and water (both tap and distilled). The strips in solution were placed in a controlled oven at 140 F for 100 hours to simulate long-term damage from immersion, vapors and heat. On examination, many strips were discolored and corroded. Only one solution caused no apparent damage, and only one caused slight vapor damage. As a result of the study, one of the solutions has been designated for use. The results have been used as examples for flight team members on the costly damage that can result from inappropriate use of these substances. A cleaning policy and procedure has been developed to ensure adequate protection from chemical exposure while protecting all team members from the dangers of bloodborne pathogens.
