Each platform unit shall be installed so that the space between adjacent units and the space between the platform and the uprights is no more than inch wide except where a qualified person can demonstrate that a wider space is necessary.

1 inch

Explanation:

According to my research on platform installations, I can say that based on the information provided within the question the space between the platform and the uprights is no more than 1 inch. This is in order to provide the necessary safety features that these platforms need to have.

I hope this answered your question. If you have any more questions feel free to ask away at .

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
