Wow Vivian
You answer my question with an accusation about my dedication to my profession!
Your comment 'If you doubt
"safety first", your workers must be also' was motivated by anger and not by a understanding of what I was saying!
I'm sure you would agree that in order to understand any subject we much first question it's relevance to the topic asking for a better understanding from the author. Only then can we enrich our own knowledge and understanding of the subject.
For example:-
If a watch is affected by the EMF given off by speakers what is the effect on the wearer?
Or if chemicals can affect the functioning of the watch what will they do to the wearers body.
Or perhaps if the battery is left in the watch for too long and causes corrosion could it also cause an exothermic reaction that might burn the wearer?
'Safety First' Slogan or Statement? do tell me!
Best Wishes
