What is the maximum inside diameter allowed for transfer hoses used to fill individual containers indoors?

The maximum inside diameter allowed for transfer hoses used to fill individual containers indoors is 1/2 inch. This regulation is in place due to safety considerations, as larger diameter hoses can increase the flow rate of LP gas, potentially leading to an uncontrolled release of gas during filling operations. Maintaining a smaller diameter helps ensure that the transfer process is managed carefully, reducing the risk of accidents or leaks.

Additionally, compliance with this specification facilitates better control over the filling process, ensuring that operators can monitor the transfer closely, minimizing the likelihood of overfilling and providing additional safety during the handling of flammable gases indoors. Regulations such as these are designed to promote safety and efficiency in the handling of LP gas.
