I have been asked if safety steps are aceptable for working at height. However, I cannot find a clear guidance on what is the difference between safety steps and a working access platform. I can see looking at them that there is a difference but is there information out there that can help me determine what the differences are between them.

Thanks for the reply. When I look through the catalogues there are a variety of "safety steps" which seem to be designed for getting things off or placing items on shelves such as in a warehouse. At the same time I also see work access platforms which look the same but bigger. I have a requirement for a platform which can be used to work at height and I have been asked if "safety steps" were acceptable. I have tried to find an explanation of hat is the main differnce between the two types and whether safety steps can be used to work at height but I can't find any information.
