Hundreds of hearts were bleeding after knowing the execution of the 3 filipinos (2 women and 1 man) in China caught smuggling illegal drugs. Hundreds of minds also do not know as to how does the execution take place? You are about to know what chemicals are being injected to the inmates.
Unless a call is received from state officials to stay the execution, the execution proceeds as planned. While a lethal-injection machine exists, and was once used by several states, most states now opt to perform the injections manually due to the fear of mechanical failure. Usually an execution team comprises prison employees. Some states use the same personnel for every execution, while others rotate the duty among several employees.
The execution team is either in a separate room or behind a curtain and cannot be seen by witnesses or the condemned. In some cases, the executioners may wear a hood to conceal their identity. At the warden's signal, the execution team will begin injecting lethal doses of two or three drugs into the IVs. Some states use multiple executioners, all of whom inject drugs into an IV tube -- but only one of the executioners is actually delivering the lethal injection. None of the executioners know who has delivered the lethal dose and who has injected drugs into a dummy bag.
