Job description fairly meaningless
Working as a porter you can expect very different role requirements depending on which hospital you work at. While some hospitals expect you to perform only portering duties. Such as dealing with patient/bed movements, waste control, theatre gas checking/ordering and hospital security. Others expect porters to perform constant cleaning duties (even 'deep cleaning'), organising office movements, fire officer duties, car parking control, restocking of clinical supplies to wards etc. Different management locally could mean you have a relatively undemanding role, or be worked to the bone and oddly with no difference in wages. Expectations are unequal and unfairly distributed.
