As a Steelworker you are required to operate sheet-metal tools and to apply basic sheet-metal layout techniques. In many Naval Construction Force (NCF) projects, sheet metal is used to protect the exterior of buildings by using flashing, gutters, and at times, complete sheet-metal roofing systems.
Other essential oils have anti-microbial actions, protect against colds and are highly effective for respiratory support, whose essences can be inhaled to address ear, nose, throat and lung problems. These include: 1  Frankincense (Boswella carteri). 2  Lavender (Lavandula augustifolia). 3  Lemon (Citrus limonom).
Peppermint is an uplifting and bright essential oil known for its antibacterial, antifungal, anti-inflammatory, pain-relieving and decongestant properties. I find it most useful though when I have a cold or headache. When applied to the chest during a cold, peppermint opens and soothes the lungs. For a headache I apply a small amount, diluted in a carrier oil, to my fingertips and massage into the temples. If peppermint oil is a bit strong for you, you can create a mix with lavender to mellow the cooling effects of the peppermint.
