Wear protective glasses when operating the laser cutting machine. If anyone else is wearing protective glasses, do not look directly into the laser. Secondly, do not allow the laser to irradiate the skin. When the laser irradiates the skin, if the energy (power) is too large, it can cause skin damage, so we should be careful when operating the laser cutting machine. Laser cutting machines often produce a large amount of dust when working. If the dust is inhaled into the human body, it will harm our health. Therefore, we should install matching dust removal devices in the laser cutting machine workshop to maintain indoor air circulation, and the operators must wear dust masks.
