Do you use gasoline in your automobile? Gasoline is extremely explosive with an explosive coeficient of over 10 times that of TNT. It is also highly poisonous, deadly to plants and animals if spilled etc.
How about cooking oil, it is a biohazard if spilled out in the open. If used in excess it is a cholesterol builder and leads to arteriosclerosis.
What about water? Drinking excess water can lead to death or a break down of electrolytes resulting in a condition known as water intoxication. Also excess water in terms of floods is a land/environment hazard
Now what about pure, non-perfumed soap. If ingested it will cause stomach distress and possible illness. If large quantities are dumped into the environment it can kill aquatic life.
I can go on and on. Because something is halal is no inference it is not dangerous if used to excess or misused. All things if used to excess or misused are dangerous.
