5 materials of safe and 5 materials of harmful
Answer (1)
Answer:5 Materials Generally Considered Safe (when used as intended): 1. Wood: A natural, renewable resource, wood is widely used in construction, furniture, and toys. It's generally non-toxic and biodegradable. 2. Cotton: A natural fiber, cotton is breathable, soft, and commonly used for clothing, textiles, and medical dressings. It's hypoallergenic for most people. 3. Glass: Used for containers, windows, and many other applications, glass is inert, non-porous, and recyclable. It doesn't leach chemicals into its contents. 4. Stainless Steel: A durable, corrosion-resistant metal often used for cookware, utensils, and medical instruments. It's non-reactive and doesn't rust easily. 5. Water: Essential for life, water (especially potable water) is considered safe for consumption and many other uses.5 Materials Generally Considered Harmful (due to inherent properties or common misuse): 1. Bleach (Sodium Hypochlorite): A strong disinfectant, but highly corrosive and can cause severe skin and eye irritation, respiratory problems, and toxic gas if mixed with other common household cleaners (like ammonia). 2. Asbestos: A naturally occurring mineral fiber, it was widely used in construction for its heat resistance. However, inhaled asbestos fibers can cause serious lung diseases, including asbestosis, lung cancer, and mesothelioma. 3. Lead (especially in paint or old pipes): A heavy metal that is highly toxic. Ingesting or inhaling lead can cause developmental problems in children, neurological damage, kidney damage, and other severe health issues. 4. Pesticides/Insecticides: Designed to kill pests, these chemicals can be toxic to humans and animals if misused, inhaled, ingested, or absorbed through the skin. They can cause a range of health effects, from acute poisoning to chronic illnesses. 5. Gasoline/Petrol: A highly flammable liquid that is also toxic. Inhaling its fumes can cause dizziness, headaches, and respiratory issues, and prolonged exposure can lead to more serious health problems, including cancer. It also poses a significant fire and explosion hazard.
