Most tradespeople don't know enough about their tools and underestimate their danger, according to an Australian manufacturer.
Saint-Gobain managing director Steven Chaur told Australian Mining there was a lack of training and understanding in most tradespeople.
"Angle grinder wheels spin at 12,500rpm, which is around 300km/h," he said.
"Tradespeople in general don't think about things like that."
"You'd be surprised how many people don’t wear the proper personal protective equipment."
Chaur said an increased knowledge of equipment was becoming increasingly important because the high Australian dollar was flooding the local market with cheap products.
"There's an influx of cheap imports coming in and a lot of them are coming from Asia," he said.
"I'm not saying Asia is a bad place to source products, but there has been a real question mark over the quality of some of these products."
"If one of those wheels bursts, they might be half the price, but they might actually kill you too."
Earlier this year Saint-Gobain opened a $250,000 training centre in Victoria offering practical and e-learning training facilities for tradespeople.
The centre is also designed for product testing and research and development.
