Harmful Effect About Each Object
Candle - The harmful effects of candle smoke included lung inflammation and toxicity, arteriosclerosis, and ageing effects on chromosomes in the lungs and spleen. Ultimately, this all leads to an increase in particulate air pollution (specifically, indoor air pollution).
Alcohol-Memory loss.
Copper Wire-The risks of burning copper include the risk of inhaling toxic fumes, burns from hot copper, and the risk of fire due to copper exploding and setting nearby trees or buildings alight
Muriatic Acid- Eye and Skin Exposure. Muriatic acid skin and eye contact produces severe burns, ulceration, and scarring. The severity of the burns depends directly on the strength of the solution.
Vinegar- It can cause stomach problems such as nausea and abdominal pain.
II. List three ways in handling hazardous materials at home:
1.Wear gloves or ask for help if the material is poisonous etc.
2.Always make sure that the guardian has allowed you to touch these objects
3.NEVER let children touch these objects/items
