When working in a high heat environment - including gas welding and cutting, arc welding and carbon arc and plasma cutting - you are on a number of risks that are specifically exposed to:
Molten metal,
Toxic gases, fumes and vapors
Harmful radiation
Excessive noise
Electric shock
Fire hazard
Personal protective equipment is an important step to protect against these threats (and in most cases, a requirement of OSHA) is. The nature of workcarried out the safety equipment to carry it to dictate. However, there are five categories of equipment are taken into account, where all should be called to work.
Respirators: Respirators offer protection against the inhalation of noxious gases, smoke and fumes. Respiratory protection must be considered when the hot work in confined or enclosed spaces is carried out. Air-purifying respirators should be worn when working on this hot surfaces that contain lead, cadmium or mercury. DeliveredAir respirators (air) should line respirators are used when hot work is performed on beryllium. Respirators may also be necessary when working on surfaces covered with toxic substances such as solvents or paints, since the high temperatures, these materials evaporate.
Eye protection: Appropriate eye protection is important that you protect your eyes from both ultraviolet (UV) and infrared (IR) radiation. Are welding, cutting, burning and goggles in the shadows, are used toProtection against UV and IR radiation. To protect your face materials such as slag, fly, a face shield should be used in conjunction with safety glasses. Welding helmets with shaded viewing window ports are used during the carbon arc welding in the face, protect the neck, and eyes from UV and IR radiation. When selecting eye protection for hot work, it is very important to ensure that the correct lens shading is used for the work performed. (And remember that anyone working or standing near the work areashould also wear appropriate eye protection.)
Protective Clothing: Hot work (obviously) produces heat, creating a burn hazard. Protective clothing helps to reduce the possibility of burns from sparks and slag. For high temperatures, is the best clothing made of leather or flame resistant clothing. When wearing leather or fire-retardant clothing, it is important to remember that the protection they will be questioned if they are contaminated by oil, grease, solvents or other offerflammable or combustible material or, if it is in poor condition (holes, wear, etc.). Pants should not have cuffs. Even if clothes have open pockets, the pockets have closed Velcroed or tape to prevent sparks or slag from the input.
Foot Guard: Heavy objects (metal plates, for example) and falling sparks, and slag can hurt foot. High-top leather boots or low-top leather boots with leather gaiters protect from sparks and slag. Toto the toes from heavy objects that should be omitted to protect the safety boots (steel toe) boots.
Hand and wrist protection: hand and wrist protection are also important, because high temperatures PPE suspend duties cuts and burns your hands (even with heat and UV or IR radiation). Leather welding gloves usually provide the necessary protection during the hot work. Leather gloves offer a degree of cut protection-an important factor in dealing with plates of metal or other sharpMaterials. Most suitable for carbon-arc welding processes, long-cuff leather gloves are, and for welding, cutting or burning, short-cuff welding gloves. Such as protective clothing in order to provide sufficient protection to leather welding gloves in good condition and free of combustible and flammable materials such as oils, greases, and solvents.
Other PPE posts
Other PPE, which should also be considered depending on the task and work area:
ConsultationProtection for environments with a very loud noise temporarily or persistent loud noise.
Head protection (ie, a hard hat) for work, where there is potential danger from overhead falling objects or materials.
Personal flotation devices to work in an area where there is the potential of falling into the water.
Fall protection systems such as positioning systems or personal fall arrest systems for work performed in the highest.
