  In other words, in an EPC contract, the EPC contractor (EPCC) agrees to deliver the keys of a commissioned project to the owner for an agreed amount, just as a builder hands over the keys of a flat to the purchaser. An owner decides for an EPC contract for several vital reasons.
Tetanus is a serious bacterial disease that affects your nervous system, leading to painful muscle contractions, particularly of your jaw and neck muscles. Tetanus can interfere with your ability to breathe and can threaten your life.
Tetanus (lockjaw) causes painful tightening of the muscles, usually all over the body. It can lead to locking of the jaw so the victim cannot open the mouth or swallow. Tetanus leads to death in about 1 out of 10 cases. Diphtheria is spread from person to person. Tetanus enters the body through a cut or wound. The tetanus and diphtheria toxoids vaccine (also called Td) is used to help prevent these diseases in adults and children who are at least 7 years old. This vaccine works by exposing you to a small dose of the bacteria or a protein from the bacteria, which causes the body to develop immunity to the disease.
