Nothing in FAR and no standard FAR clause authorizes a CO to unilaterally update, add, or delete clauses in a contract after award. None of the five Changes clauses, FAR 52.243-1 through -5, empower a CO to do that. Thus, with a few exceptions, which are discussed below, changes to FAR clauses â revisions, additions, and deletions â must be accomplished through supplemental agreement [(bilateral modification). See FAR 43.103(a)(3).
What else do I need to know about rib fractures? Flail chest occurs if 3 or more of your ribs are broken in 2 or more places. This condition may make it hard for you to breathe. Normally, when you take a breath, your rib cage expands. Flail chest prevents your ribs from expanding. This can cause your broken ribs to push inward on your organs. What are the signs and symptoms of a rib fracture? Chest wall pain that worsens when you breathe, move, or cough
Broken (fractured) or bruised ribs are usually caused by a fall or blow to the chest, or occasionally by severe coughing.They can be very painful, but will normally improve within about three to six weeks. If you think you've injured your ribs, you'll often be able to look after yourself at home.n most cases, you can take care of broken or bruised ribs at home. While your injury heals, pain relief is very important, as it will hurt every time you breathe in or cough. Taking shallow breaths and not coughing to avoid pain will only put you at risk of a chest infection.
