An increased ACTH result can mean that a person has Cushing disease, Addison disease, or ectopic ACTH-producing tumors. A decreased ACTH result can be due to an adrenal tumor, steroid medication, or hypopituitarism.
All fabrics will burn, but some are more combustible than others. Untreated natural fibers such as cotton, linen and silk burn more readily than wool, which is more difficult to ignite and burns with a low flame velocity. The weight and weave of the fabric will affect how easily the material will ignite and burn. Fabrics with a tight weave - wool, modacrylic, 100 percent polyester and those that are flame-retardant treated are good choices.
Occupational Safety & Health Administration. Combustible Dust: An Explosion Hazard. Any combustible material can burn rapidly when in a finely divided form. If such a dust is suspended in air in the right concentration, under certain conditions, it can become explosible. Even materials that do not burn in larger pieces (such as aluminum or iron), given the proper conditions, can be explosible in dust form. The force from such an explosion can cause employee deaths, injuries, and destruction of entire buildings.
