Hi I am having an issue with a parent who wants his son to wear a face mask when sanding a 60mm x 60mm square of laminated acrylic with wet and dry paper. My stance is I have a new, clean , well ventilated workshop. We used the paper dry then wet, the kids washed their hands after. I consulted the relevant British Standard and CLeaps and am fine unless we do any machining which I am not planning. I have little funding or resources so cannot afford this. Have I missed something here? I should say this is a small focussed practical task to teach basic skills, my kids have non. They can’t even use scissors. This kid however does do a lot of stuff at home and has very good skills but has not worked with this material before I have been teaching DT for over 20 years, a former HOF for over 8 and never heard the like.....maybe being a woman doesn’t help!
