LP gases, commonly known as propane and butane, are colorless and odorless in their natural state. To ensure safety, these gases must be odorized before delivery to help detect leaks. The specific concentration limit for odorization is crucial as it allows for the safe identification of gas presence without posing a significant risk of explosion or fire.

The correct choice indicates that the odorant must be added to a concentration not exceeding 1/5 of the lower limit of flammability in air. This means that the effective concentration level of the odorant is safe and effective enough to provide a warning odor well below the flammability threshold of the gas. This standard is employed to avoid situations where the gas could ignite before the leak is detected through smell.

This specific concentration helps to strike a balance; it ensures that the odor is strong enough for detection without introducing excessive amounts of an odorant that could pose health or safety risks itself.

Setting the limit at 1/5 of the lower flammability limit effectively allows for both safety and practicality, enabling users to identify potentially dangerous leaks while still maintaining a safe level of the odorant used.
