All that glass dust and so few respirators. No ear protection in sight. Open, spinning cutting wheels with no guards for fingers, feet, knees. The skill is amazing. The conditions are criminal.Sometimes i don't realise how easy my life is until I see something like this.I applaud those skilled hardworking men in spite of the poor condition they have to work under they're they are turning out some magnificent products so many God bless them and keep them safe.
