Personal protective equipment consists of protective devices worn by the individual - similar to other work protection such as hearing protection, protective goggles or work clothing. This includes, for example, ventilated welding helmets. They have a ventilating filter device, usually placed at the back. Filtered air is fed directly into the welding helmet via a ventilation hose.
The task of personal protective equipment is not to collect and filter welding fume emissions, but to protect the welder from them. The protective effect is therefore limited to the welder and to the duration of use of the ventilated welding helmet.
The welding fumes are distributed unhindered in the working area and in the hall if no other protective measures are used. If the personal protective equipment is taken off, there is no longer any protection against diffuse emissions. This applies to all employees in the hall.
