Rugby Referee Whistle Hygiene
As we start a new decade, for referees it is important to ensure that their individual whistle remain in clean and safe condition for reuse. This short review is intended to update our refereeing community on hygiene standards for whistles, particularly with the advent of a new coronavirus (COVID-19) potentially circulating within the global community. Some background on whistle contamination. Firstly, most of the germs on and within the whistle will be your own. However, where the whistle is not regularly cleaned, then saliva, skin cells, bacteria and fungi, can and will accumulate both within the mouth piece and also within the whistle chamber. The best way to remove this biological soiling is to regularly clean and sanitise the whistle as indicated below:
Cleaning the whistle:
A. Make sure that the whistle is attached via a string or cord or another lanyard;
B. Immerse the entire whistle into a warm soapy solution (normal, manual dishwashing solutions are absolutely ok for this use). The temperature of the solution should not be hot (30C is ideal, but you don’t need a thermometer);
C. Get a new soft bristled toothbrush and gently rub around and into the inside of the mouth piece, and also the whistle air window (where the air comes out);
D. This cleaning should be done for at least 30 seconds;
E. Then rinse off the soapy solution under running cold water.
Sanitising the whistle
A. Boil some water and whilst holding the whistle using a pair of tongs (so you don’t burn your hand or fingers), pour the boiling water over and into the whistle;
B. You should pour the water gently over the whistle for at least 15 seconds if possible.
Drying the whistle
A. Hang the whistle using the lanyard over a piece of disposable paper for at least an hour or so and allow to dry.
The goal of the process is two-fold. Firstly, cleaning and sanitising the whistle will remove biological material and existing micro-organisms that can build up and lead to unpleasant odour, unpleasant taste, and possibly lead to oral infections. Secondly, your whistle will last longer.
