What are some examples of contaminants?
For example, contaminants such as glues, cements, resins, and muds have much greater adhesive properties than elemental mercury and consequently, are difficult to remove by physical means. Physical removal methods for gross contaminants include scraping, brushing, and wiping.
Why is decontamination important?
While decontamination is performed to protect health and safety, it can pose hazards under certain circumstances. Decontamination methods may: Be incompatible with the hazardous substances being removed (Le., a decontamination method may react with contaminants to produce an explosion, heat, or toxic products).
What is decontamination in hazardous waste?
Decontamination - the process of removing or neutralizing contaminants that have accumulated on personnel and equipment - is critical to health and safety at hazardous waste sites. Decontamination protects workers from hazardous substances that may contaminate and eventually permeate the protective clothing, respiratory equipment, tools, vehicles, and other equipment used on site; it protects all site personnel by minimizing the transfer of harmful materials into clean areas; it helps prevent mixing of incompatible chemicals; and it protects the community by preventing uncontrolled transportation of contaminants from the site.

Elevation uses the force of gravity to help reduce the blood pressure in the injured area and thus aids in slowing down the loss of blood through the wound opening. However, direct pressure on a thick pad over the wound must be continued.
How long does it take for a wound to heal?

How to control bleeding from an open wound?
Severe bleeding of an open wound can usually be controlled by pressing with the palm of one hand on a compress of cloth over the entire area of the wound. A thick pad of sterile gauze is preferable, but any soft, clean cloth can be used in an emergency. Even unclean material can be used, but only if nothing better is immediately available.
What is a tourniquet?
A tourniquet is a wide band of cloth or other material placed just above a wound to stop all flow of blood. Do not use a narrow band, rope, or wire. Application of a tourniquet can control severe bleeding from an open wound of the arm or leg but is rarely needed and should not be used except in a critical emergency where direct pressure on the appropriate pressure point fails to stop bleeding. The use of a tourniquet is dangerous. Properly applied, the tourniquet will stop all blood circulation to a limb beyond the point of application. But if it is left in place for an extended period, uninjured tissues may die from lack of blood and oxygen. Releasing the tourniquet tends to increase the danger of shock, and bleeding may resume. If a tourniquet is improperly applied (too loosely), it will not stop arterial blood flow to the affected limb, but will only slow or stop venous blood flow from the limb. The result is increased, instead of controlled, bleeding from the wound. The decision to apply a tourniquet is in reality a decision to risk sacrifice of a limb in order to save a Life. Once a tourniquet is applied, care by a physician is imperative.
