| If you have: | Then: | |
| Hose subject to container pressure | Design it with a minimum | |
| – | Working pressure of 350 psig | |
| AND | ||
| – | Burst pressure of 1750 psig | |
| Hose and their connections | Design them for the maximum low side working pressure when located on either: | |
| – | The pressure reducing valves on devices discharging to atmospheric pressure; | |
| OR | ||
| – | The low pressure side of flow control. | |
| Design, construct, and install so there is no leakage when connected. | ||
| Liquid transfer hose that is not drained of liquid upon completion of transfer operations | Equip with an approved shut off valve at the discharge end. | |
| Prevent excessive hydrostatic pressure in the hose. | ||
| Hose with an outside diameter one-half inch and larger | Make sure the hose is marked and legible at five foot intervals. | |
