10、art 2: Working platforms and walkways; Part 3: Stairways, stepladders and guard-rails; Part 4: Fixed ladders.It has been assumed in the preparation of this British Standard that the execution of its provisions will be entrusted to appropriately qualified and experienced people, for whose use it has
11、been produced.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Its requirements are expressed in sentences in which the principal auxiliary verb is “shall”.Commentary, explanation and general informative material is presented in smaller italic typ

In these cases plates shall be drilled and count
42、ersunk before being bolted to the supporting structure.8.4 Toe platesToe plates specifically required around cut-outs in plates shall be formed from flat sections or angle sections before being fixed securely to the plate by welding, bonding, or bonding and bolting.
