First Aid Measures

Ingestion

Even though a substance may be considered non-toxic for the amount ingested or packaged, it should not be considered as non-toxic in any amounts. Even ingestions of various foodstuffs can cause adverse symptoms if large amounts are eaten (green apples, garlic, onion). The most important fact to remember is to treat the patient not the poison, especially when the diagnosis is unknown. Knowing that the product is listed as non-toxic helps avoid overtreating the patient or being over zealous in getting a patient to professional medical care. If there is a question of simultaneous ingestion of a product which may be more dangerous, the management on the more toxic agent should be consulted.

Inhalation

Although inhalation of common dust may not be considered toxic, it is certainly a hazard if there is inhalation of too many particles. Individuals should be removed from exposure to too high a concentration of even relatively non-toxic substances.

Skin

Foreign materials spilled on the skin may not represent a toxic or irritation hazard in small quantities, but may produce adverse effects if applied in large quantities or if used over a significant period of time. Whenever possible, foreign materials should be removed from the skin with simple washing. Should skin irritation or erythema occur, a patient may wish to seek medical assistance.

Eyes

Foreign materials in the eye may not cause a toxic reaction, but injury from a foreign body may occur. In such cases, the patient should be observed for eye irritation and should seek medical assistance if the irritation becomes significant.
