Strokes produce many neurological issues. Foot drop is usually a neurological issue caused by damage to the nerves in the leg which can be the initial result of stroke. Weakness of the ankle and foot will cause all of the symptoms to occur. Drop foot after a stroke can be either neurological or muscular damage. The muscle is rarely damaged but can become dysfunctional due to atrophy associated with lack of use and exercise. Tingling of the lower leg and foot can also be present.
Two important chemical hazard labeling systems used in healthcare facilities are the Hazardous Materials Identification System (HMISÂ®) and the National Fire Protection Association (NFPA) NFPA 704 system.
The American Chemical Society (ACS) Committee on Analytical Reagents sets the specifications for most chemicals used in analytical testing. Currently, ACS is the only organization in the world that sets requirements and develops validated methods for determining the purity of reagent chemicals. These ACS chemical specifications have also become the de facto standards for chemicals used in many high-purity applications.
