Beryllium copper hazards. Beryllium copper BeCu also known as copper beryllium CuBe beryllium bronze and spring copper is a copper alloy with 053 beryllium and sometimes other elements. Beryllium copper combines high strength with non-magnetic and non-sparking qualities. It has excellent metalworking forming and machining propertiesIt has many specialized applications in tools for hazardous environments.
Beryllium is a chemical element with the symbol Be and atomic number 4. It is a steel-gray strong lightweight and brittle alkaline earth metalIt is a divalent element that occurs naturally only in combination with other elements to form minerals. Notable gemstones high in beryllium include beryl aquamarine emerald and chrysoberylIt is a relatively rare element in the universe usually.
Beryllium is used industrially in three forms. As a pure metal as beryllium oxide and most commonly as an alloy with copper aluminum magnesium or nickel. Beryllium oxide called beryllia is known for its high heat capacity and is an important component of certain sensitive electronic equipment.
Beryllium alloys are classified into two types. High beryllium content up to 30 beryllium. The purpose of medical surveillance is to detect and eliminate the underlying causes of observed health effects from hazards.
Medical surveillance programs can contribute to the success of workplace health and safety programs by identifying potential problem areas and verifying the effectiveness of existing control and prevention programs. Under the beryllium standards 29 CFR 19101024. However most or all of the hazards of welding may still exist.
In gas cutting a torch is used to heat metal to its auto-ignition temperature and a stream of oxygen is then trained on the metal turning it into a metal oxide that flows out as slag. Acetylene is the most common gas used for fueling cutting torches. When mixed with pure oxygen in a cutting torch assembly an acetylene flame can.
