When you take a look at a bottle like the one in the picture below, the first thing that comes to your mind is usually that it contains what you assume would originally be in the bottle; water.
More so, many Nigerians are unconscious experts at recycling the items they use everyday. Actually, bottles are recycled more than any other item in Nigeria. People use water bottles to store oil, kerosene, thinner (transparent chemical) and the like.
Furthermore, when bottles are recycled for use in occupational work environments, they must be labeled to indicate the present content. Imagine that a painter goes off to lunch, buys and drinks a bottle of 7up and then subsequently buys the thinner his master asked him to buy in the bottle and goes right back to work. The chances that a thirsty colleague of his will drink from the bottle is high if it is not adequately labeled.
Label all containers in occupational work environments, it is the safe thing to do.
