The material in this post is extracted from Chapter 10 — Safety in Design — of the book. An overview of the design requirements for stairs, ramps and platforms are provided in this section; fixed ladders are discussed in the next section.

The material here does not provide detailed guidance regarding the measurements and specifications — such information can be obtained from the many of the standards and regulations that cover these items. Ramps are used in areas where there is high traffic and/or frequent use of wheeled carts that are used to move equipment. Ramps will be used where the elevation change is small and there is sufficient room to allow for a gentle slope. Stairs should generally be used over ladders in the following situations: • When routine movement between two levels is required; • For routine tasks such as gauging, inspection and maintenance; • Employees could be hand-carrying heavy or bulky tools and/or equipment. • There is a potential for exposure to hazardous materials at the elevated location and immediate escape is required.

Regulations and Standards The design of stairways, ladders and ramps is covered by many regulations and standards, some of which are listed below. These standards provide considerable detail to do with topics such as the spacing between stair treads and the height of hand rails. • ANSI A64.1-1968 • ASTM F 1166 – 95a, Standard Practice for Human Engineering Design for Marine Systems, Equipment and Facilities, 1995. • ABS Guidance Notes on the Application of Ergonomics to Marine Systems, January 1998. • DOT/FAA/CT-96/1, Human Factors Design Guide for Acquisition of Commercial-Off-The-Shelf Subsystems, Non-Developmental, and Developmental Systems, January 15, 1996. • MIL-STD-1472F, Department of Defense Design Criteria Standard, Human Engineering, 23 August 1999. • MIL-HDBK-759C, Department of Defense Handbook, Human Factors Engineering Design Guidelines, 31 March 1998.

Figure 10.1 Stair Terminology The following terms are shown in Figure 10.1. Angle of Ascent / Inclination. The angle of ascent for stairways should be in the range 30 to 50° and the vertical elevation should exceed 24 in. The rail on the stair sides used to provide balance when ascending or descending. The rail provided on the open side of an elevated flat walking or working surface to protect workers from falling to a lower surface. It is also called a guardrail.
