Making our world <br /> more productive <br /> Min Max Consequences of Deviation Safety Systems/Operator <br /> Actions <br /> Tank Temperature -40 °C 85 °C Overheating of polymer liner Dispenser protocols are <br /> (potential permeation of developed using "worst case" <br /> hydrogen through liner) scenarios with an additional <br /> factor of safety to calculate <br /> fill rates. If actual tank <br /> temperature exceeds <br /> permissible limit, vehicle will <br /> send a non-SIL shutdown <br /> command to the dispenser. <br /> Tank Pressure 2 MPa 43.75 Over-Pressurization of fuel tank Dispenser protocols are <br /> MPa (potential damage/failure of developed using "worst case" <br /> (H35) tank) scenarios to calculate end <br /> 87.5 pressures. If actual tank <br /> MPa pressure exceeds permissible <br /> (H35) limit, vehicle will send a non- <br /> SIL shutdown command to <br /> the dispenser. There are <br /> additional PRVs on the <br /> dispenser and vehicle tank to <br /> prevent over-pressurization. <br /> Ambient -40 °C 50 °C Overheating of polymer liner Dispenser protocols were <br /> Temperature and (potential permeation of developed assuming an <br /> Hydrogen hydrogen through liner) ambient and a hydrogen <br /> Temperature temperature window. The <br /> dispenser is designed to <br /> measure these parameters and <br /> not start(or shut-off) the <br /> filling process if violated. <br /> Page 38 of 38 <br />
