Procedures are extensively employed to assist with working safely. They are sometimes called safe work methods statements (SWMS, pronounced as 'Swims'). They are usually preceded by various methods of analyzinganalysing tasks or jobs to be performed in a workplace, including an approach called job safety analysis, in which hazards are identified and their control methods described. Procedures must be suited to the literacy levels of the user, and as part of this, the readability of procedures is important.<ref>Taylor, G.A.
