Abstract
Coronavirus (COVID-19) pandemic is one of the defining global health crises the world has ever faced after world war two. From the time of its emergence in Wuhan, China, the virus has spread to all the continents. Every day, people are losing their lives, jobs and income, with no way of knowing when normality will return as a result of the spread. The pandemic spreads primarily when people are in close contact or when one person or more inhale(s) small droplets produced by an infected person who is coughing, sneezing, talking or singing. Due to this, the World Health Organization (WHO) gave advice to the public on how to contain COVID-19 spread. They are: social distancing, regular hand washing, hand sanitizing, temperature measurement, self-isolation of infected persons and the use of nose mask. This research endeavor focuses on design and development of a mechanical means of safe hand washing. The machine major components are frame, liquid soap dispenser, water reservoir, water taps, waste water tank, piping, foot pedals, and wash hand bowl. The machine was designed to work without electricity as it is foot pedal powered. The foot pedal acts as an actuator either to depress water tap or liquid soap dispenser. Machine design capacities for both intermediate and full level of depression are respectively 94 users in 16 minutes and 68 users in 12 minutes. Direct implication is that 2,880 users can engage it in a day of 8 hours operation for intermediate depression, leaving number of batches for prolonged use averagely as 30 batches. For full pedal depression, 2,720 users will engage the machine for 8 hours, leaving number of batches as 40. Social distancing was measured as 1 meter when engaged simultaneously by users. The materials for the fabrication of the machine were sourced locally so as to minimize the cost of production and as well make it readily available for low income earners in developing nations. Findings from this technical brief should be given wide adoption as hand washing has become a recommended way of staying safe in public places.
