Portable water purification devices are self-contained, easily transported units used to purify water from untreated sources (such as rivers, lakes, and wells) for drinking purposes. Their main function is to eliminate pathogens , and often also suspended solids and some unpalatable or toxic compounds .
Gastric lavage is used infrequently in modern poisoning treatment. Some authorities have actually suggested that it not be used routinely, if ever, in poisoning situations. [4] Lavage should only be considered if the amount of poison ingested is potentially life-threatening and the procedure can be performed within 60 minutes of ingestion. [5]
One formulation is (by weight) lactic acid 12–18%, gluconic acid 2.50–3.75%, lauramine oxide 1.50–3.25%, with the remainder being water. [3] The product also contained phosphoric acid at one time, [ citation needed ] but it is now phosphate-free.
An "incident" of chemical food contamination may be defined as an episodic occurrence of adverse health effects in humans (or animals that might be consumed by humans) following high exposure to particular chemicals, or instances where episodically high concentrations of chemical hazards were detected in the food chain and traced back to a particular event.
It is not effective for a number of poisonings including: strong acids or bases, iron, lithium, arsenic, methanol, ethanol or ethylene glycol. [7] Although activated charcoal is the most commonly used agent for GI decontamination in poisoned patients, medical professionals use discretion when determining whether or not its use is indicated.

During. The FDA says people should keep their refrigerator and freezer doors closed when power has been lost. While a refrigerator will keep food cold for about 4 hours if unopened, a full freezer ...
Oxygen should not be administered unless SpO 2 levels are below 92%, as high concentrations of oxygen intensify the toxic effects. [43] [44] Death may occur up to 30 days after ingestion. Lung injury is a main feature of poisoning.
Alkaline water (above pH 7.0) does not necessarily mean that lead or copper from the plumbing system will not be dissolved into the water. The ability of water to precipitate calcium carbonate to protect metal surfaces and reduce the likelihood of toxic metals being dissolved in water is a function of pH, mineral content, temperature ...
