Laser has the same biological effects (general effect, light effect, pressure effect, and electromagnetic field effect) as ordinary light. This biological benefit brings benefits to human beings. If it is not protected or not well protected, it will also affect eyes, skin, etc. As well as direct or indirect damage to human tissues such as the nervous system. In order to ensure the safety and protection of the laser welding machine, the laser hazard must be strictly controlled, and engineering control, personal protection and safety management must be done well.
Engineering control refers to the safety measures taken on the structure of the laser or laser processing system. It mainly includes: protective cover-to prevent staff from receiving more than the maximum allowable exposure; safety chain-refers to the protective cover connected to the protective cover. Automatic device to avoid radiation when the protective cover is removed; safety light path-to close the light path that may cause combustion or secondary radiation when irradiated; key switch-generally refers to the laser turning when the key is removed; To prevent the laser beam from exceeding the controlled processing area, a beam terminator or attenuator can be used.
It mainly refers to wearing fire-resistant and heat-resistant laser protective clothing, wearing laser protective glasses that can selectively attenuate specific laser wavelengths, wearing laser protective masks for driving recorder UV laser sources, and wearing to avoid direct or scattered laser Damage protective laser gloves.
Safety management mainly includes setting up specialized agencies or personnel, and clarifying responsibilities and rights: including safety training and medical supervision.
