Safety stepladders

The applications of the SRK, GEMS, stepladder and sequential block diagram models to human error in process safety can be summarized as follows ... 

This method is based on the Rasmussen stepladder model described in Chapter 2. It was first described in Embrey (1986). The basic units of CADET are the critical actions or decisions (CADs) that need to be made by the operator usually in response to some developing abnormal state of the plant. A CAD is defined in terms of its consequences. If a CAD fails, it will have a significant effect on safety, produchon or availability.

The use of ladders and stepladders are not banned under health and safety law. The law says that ladders can be used for work at height when a risk assessment has shown that using equipment offering a higher level of fall protection is not justified because of the low risk and short... 

Some other common misuses of ladders are sources for injury as well. Leaning a stepladder against a wall or pole in the same manner as a single or extension ladder is an OSHA violation for good reason. The ladder can easily slide down the resting surface, allowing the worker to fall. Ladders should never be tied together in any manner to obtain additional reach. Another common safety violation exists when ladders are used on top of an aerial lift, scissor lift, truck bed, or other elevated surface or device. It is much more efficient to properly plan and select the correct size ladder for the project. 

A previous chapter used an example of Joe falling from a stepladder (see Figure 2.6.12). lliat analysis was undertaken using the Incident Model and it was discussed in terms of the organisational responsibilities for health and safety. 

This is in response to your letter submitted April 27, 2006 to the Occupational Safety and Health Administration (OSHA). Your inquiry addresses the use of portable stepladders and fall protection. We apologize for the long delay in responding.
