Last week, the Mechanical Contractors Association of America put out a reminder that hand sanitizers that contain alcohol are flammable.
Current guidance from the Centers for Disease Control suggests that individuals in clinical settings should be using hand sanitizer (an alcohol based hand rub with greater than 60% ethanol or greater than 70% isopropyl alcohol) due to greater compliance over soap and water. If hands are visibly soiled or if an alcohol based hand rub are not available, hands should be washed with soap and water for at least 20 seconds.
When using an alcohol based hand rub, you need to make sure that your hands are dry and all of the alcohol has evaporated off before touching anything. The MCAA put out the reminder that hand sanitizers with alcohol are flammable due to an incident where an employee used hand sanitizer per guidelines to sanitize his hands. However, the alcohol had not evaporated off of his hands when he touched a metal surface. The remaining alcohol in the hand sanitizer on his hands was ignited by static electricity. The employee was able to get to a sink and extinguish the flames however he suffered first and second degree burns on his hands.
When using hand sanitizer please be aware of any risks of flames or sparks and make sure that you allow your hands to fully dry before touching anything that can generate a spark or a static discharge.
