There are three primary categories to choose from: C5, C7, and C13. A UK Power Lead with 3 IEC C13 Pins is the most common type used in Europe. A USA Power Lead with 2 IEC C14 Pins is more common in America. And Japan's Power Leads use C7 Pins.
Each category of lead has various grades available. The highest grade for any given product is not always obvious when you first look at it. For example, a C7 power lead can be labeled as "Grade B" or "Class II". This means that even though it looks like it should be able to handle much higher current than it actually can. And a C13 lead can be labeled as "Class 1", which tells you that it can handle current levels not expected of standard power leads.
The differences between these leads are not always apparent from just looking at them. For example, a C7 lead with two lower grade pins might seem safe enough for an average household. But if you were to connect multiple units of this lead together, they would be able to pull down very high current levels from a hot wire back into itself. This could easily cause damage to other parts of your house wiring system or even start a fire.
Lead's qualities that make it useful in a broad range of applications include its high density, malleability, lubricity, flexibility, electrical conductivity, and coefficient of thermal expansion, as well as its low elastic modulus, elastic limit, strength, hardness, and melting point. Lead is also relatively inexpensive compared with other metals.
Lead has been used for thousands of years because of its many advantages. It is the most common element used in bullet casings. Lead is also used in ammunition to increase the weight of the projectile so that it will fly farther or be more accurate. When bullets strike flesh they often leave small fragments behind. These fragments are called lead pellets or shot. The body naturally removes these particles by passing urine, defecating, and sweating. However excessive exposure to lead can have adverse effects on the human body. Individuals who work with lead may be at risk of developing serious health problems if they are not careful about what they eat and drink and how they handle materials that contain lead.
People may be exposed to lead through their food, water, air, and objects that contain lead. The main source of lead for individuals is likely from lead-based paint which is no longer used in new homes but can still be found in older buildings. Other sources include old gasoline pumps and lead-containing solder used in electronics. Of particular concern are children's toys that may be made of plastic containing lead or wood that has been treated with lead-based paints.
Lead and lead compounds have been detected in a wide range of household items, including paint, ceramics, pipes and plumbing materials, solders, gasoline, batteries, ammunition, and cosmetics. Lead may have entered the environment as a result of these previous and ongoing usage. It can also be released into the atmosphere through mining or when old lead-based products are discarded in landfill sites.
Once in the body, lead is toxic to many organs including the brain, kidneys, lungs, and blood. Children are particularly at risk from lead because it can damage developing brains and bodies. Older people may experience symptoms such as headache, nausea, abdominal pain, diarrhea, joint pain, and changes in mood or behavior.
The best defense against lead exposure is to avoid lead-containing products whenever possible. These include house paints with lead pigments, ceramic tile used in homes built before 1978, and brass fish tanks and faucets. If you do find lead inside your home, take action by having all lead-contaminated items removed and disposed of in an approved hazardous waste disposal site.
Lead sheets are utilized in a variety of sectors for a variety of purposes. This lead is often used for roofing and flashing, tank lining, soundproofing, radiation shielding, and corrosion prevention. The lead sheet may have an adhesive on one side which is applied to another surface or it may be held in place by mechanical means.
The lead sheet itself is made up of two parts: the metal and the oxide layer. When you roll the metal into strips, it creates a soundboard. The metal can be any thickness but is usually between 1/8" and 5/16". Lead is a soft metal so it will roll out easily. The thicker the metal strip, the better it is for keeping out noise.
The metal layer is covered with an oxide film that protects it from corrosion when it is exposed to moisture. This allows the metal to retain its shape and not bend or fold under pressure. You should avoid scraping off this protective layer because it will reduce the lead's efficiency as well as its durability.
When installing lead roofing, first apply a thin coat of oil to the metal to prevent it from bending or breaking when you drive nails into it. Next, cover the entire surface with a thin layer of asphalt shingle material.
