In the lessons

In everyday and safety life chainsaws are used by tree surgeons, foresters and farmers. They are very dangerous, so users wear helmets, goggles, ear defenders, gloves and special trousers; children must stay well away. In art, people make chainsaw sculptures from tree trunks. Phrases: chainsaw safety, chainsaw carving.
