T51-T65: Toxic effects of substances chiefly nonmedicinal as to source

The toxic effects of substances chiefly nonmedicinal as to source refer to a group of conditions caused by exposure to harmful chemicals or substances not normally intended for ingestion or absorption into the body. These substances may include detergents, cleaning products, fuels, paints, plant toxins, and more. Exposure can occur through various means such as swallowing, breathing in fumes, or skin contact. Symptoms can vary widely depending on the substance and the amount of exposure but may include nausea, vomiting, headache, skin irritation, difficulty breathing, and changes in consciousness. These conditions can affect multiple body systems and may result in serious health issues if not appropriately addressed. Progression of the conditions depends on the nature of the substance involved and the promptness of decontamination or medical intervention.
