The means of egress must be located so as not to require workers to travel more than 25 feet (7.62 meters) laterally within the trench. Lifting platform is a very crucial part of crane lifting safety Procedure, and during construction, it is essential to follow all the safety precautions for crane lifting. 00. . Therefore, it's important that you are aware of the risks and hazards welding poses, and understand what precautions you can take to protect yourself. Electric arc and laser welding emit ultra- violet (UV), visible light and infrared (IR). Electrode holders should be in good repair and rated for the maximum capacity of equipment used. Exposure to fumes and gases can be controlled by adhering to these safety precautions. EOT cranes are associated with large number of hazards in their operation. Arc welding uses an electrode cable that powers the welding lead and a ground cable to create that circuit. 5.2.4 Support the implementation of risk control measures recommended by the RM or RA Teams. These hazards can cause accidents which may occur before,. body injuries Utilising plans and processes to ensure that all . HAZARD SAFETY MEASURES Fumes and gases produced by the . These can be obvious straight away such as electric shock or exposure to cadmium fumes, or they may show up in the long term such as lung and breathing disorders. Welding and allied processes include arc welding, oxy-fuel gas welding, open-flame soldering, brazing, thermal spraying, oxygen cutting, and arc cutting. These may cause additional inhalation and respiratory exposure concerns as mentioned previously. 2. In every welding method or process, safety is the most important element that need to take care..

Note also that this table of examples does not include all possible hazards. LEV performance can be tested for comparison to the capture velocity range 0.5m/s to 1m/s as described in the HSE guidance Controlling airborne contaminants at work (PDF) as appropriate for welding fume, soldering and liquid transfer. At present, it is estimated that more than one million workers are employed as welders worldwide with more than three million performing welding as part of their work duties. This can be very damaging to the ears and can result in hearing impairment. Welding Hazards in Confined Space No worker should work in an area with less than 19.5% or more than 23.5% oxygen content Never ventilate with oxygen Use continuous mechanical ventilation and . They also must be set properly and not mixed up. Objectives . Welding operations present several hazards to both those undertaking the activity and others in the vicinity. involve either a gas flame or an electrically generated arc. Four steps to manage the risk Step 1: Identify the risk Step 2: Assess the risk Step 3: Control the risk Step 4: Review risk controls When planning any activities which may involve working at height, the following hierarchy of control measures should be considered: Working from an existing place of work, or using an existing means of access and egress. Welding Health and safety in welding Welding poses a range of hazards to your health. Although, preventing the occupational risks is the main purpose of risk assessment, it is not possible in all situations; therefore, risks should be reduced using control measures. The causes are commonly related to welding on plated, galvanised, painted or degreased metals as well as mild steel. Regular or immediate exposure to loud noises can cause permanent noise-induced hearing loss. Strike arc and perform welding Eye injury from arc flash Burns to skin Fire or explosion Health hazards from accumulation of toxic gases within the work area Electric shock Heat stress Wear arc flash shield/helmet, insulated leather gloves and welder's jacket, steel-toed boots, apron, half-face air purifying The platform should be covered properly with safety . If welding fume cannot be eliminated, control measures should be adopted as follows: choice or modification of the welding process. Exposure to manganese can also cause adverse health effects including neurological effects similar to that of Parkinson's disease. Investigate Surroundings before Welding Begins. Exposure to various toxic gases generated during welding may produce one or more of the following effects: Inflammation of the lungs (chemical pneumonitis) Pulmonary edema (swelling and accumulation of fluids) Chronic bronchitis. Most popular fuels used with oxygen include acetylene, mapp gas, and hydrogen. Arc welding includes various hazards like dust, gas and smoke, compressed gas cylinders, harmful rays, high temperature and electric shock. 3.0 HAZARDS IN WELDING. Studies estimate approximately 30 - 40%* increased risk for welders Much of this risk is due to high rates of smoking and asbestos exposure among welders Suspected link to chromium and nickel exposure from stainless steel Possible link to radioactive thorium contained in certain tungsten electrodes used in TIG welding Here are some precautions you should take while working in confined spaces: 1. There are a number of control measures you can put in place at your organisation or on your projects to mitigate the risk inherent in excavations - keeping your assets and everyone safe in the process. 1. Hazards depend on the type of welding, the types of metals and coatings, and the welding work practices being used. Wear appropriate personal protective equipment and footwear.
