The Hazards of Lead

Lead hazard L - E - A - D. Oh, everyone knows. Or are we. It is during your childhood that you consciously know consciously that lead is a black substance in a pencil. However, when you notice that the "lead" of the pencil is actually graphite (actually a mixture of graphite and clay) you will immediately notice what you have learned. Although the chemical formulas of graphite and diamond are the same, you will be very confused if you learn that it is different both visually and economically.

The danger of lead has been described in medical research in 2000 and concerns about lead contaminated water were found in the UK in the late eighteenth century. Lead is known to be toxic to the reproductive system, liver and kidney, and the immune system. We know that for over 40 years even low levels of lead poisoning can cause nerve damage in the developing brain and that children exposed to lead have a high risk of developmental disability. The relevance between lead and human cancer is not clear, but lead has been shown to cause kidney and brain tumors in animals. Recent studies have shown that lead may increase the risk of cancer by repairing damaged DNA by impairing cell protection or by exposure to other chemicals.

Risk assessment often finds physical and technical hazards that can lead to personal injury or accident. But what if potential harm exists in the human brain? This unrecognized brain-centered hazard can explain why so many cases result from "human error". You provided training and special hazard training for new recruits and young employees hired during the busy summer (see "Summer Safety of New Young Workers"). They signed the training and it was very good. You may think that you completed your work, but it is not so.

The welder has to face a lot of physical and chemical hazards and as a result requires personal protective equipment. Employers are responsible for ensuring that employees are well prepared and trained to cope with the risks that may pose potential risks to health. Some of the main dangers that welder workers must deal with are listed below. Inhalation of particles and fumes from the welding operation may be dangerous. Most welding workers are exposed to these liquids during processing, but this is the main cause of welding work breathing problems. Asthma, pulmonary dysfunction, chronic bronchitis and skin burns are some of the most common occupational health-related problems. By properly using safety clothing such as Nomex Salopette and protective equipment such as masks and gloves, it is possible to prevent skin contact with scattered objects and sinks.
