Although aldosterone retains Sodium and water, it induces excretion of Potassium. Potassium can be induced by angiotensin II. Antidiuretic Hormone (ADH) ADH is a polypeptide, which is secreted by the hypothalamus, and it is stored in the posterior pituitary gland. ADH is released when water level is low in the blood stream. ADH regulates the body water level by concentrating urine and thereby reducing urine volume.
Gas masks are essential in an evacuation of a biological or chemical disaster. Knowing how to use it properly will increase your chance for survival. There are different types of gas masks, and you should follow the specific instructions for that particular mask.
Some gas masks are also respirators, though the word gas mask is often used to refer to military equipment (e.g. field protective mask). The user of the gas mask is not protected from gas that the skin can absorb. Most gas mask filters will last around 24 hours in a nuclear biological chemical (NBC) situation.
