GISAI Data • There are approximately 12500 accident cases with an accident/ penalty[1] report reported between January 1998 and February 2004. • This is an underestimate of the total number of work related accidents as many go unreported [1] Sometimes referred to as prosecution-reports

1.1.1.1 Mobile ladder accidents The three mutually exclusive barrier failure types that directly led to falls:- • 67% LADDER STABILITY fails: • Mostly due to setting it up incorrectly • The rest due to • an unstable surface • being hit by something • poor position of the person on the ladder • 29% USER ABILITY fails • mostly due to loss of control over body movement such as due to the force of using a tool or a misstep • 4% LADDER STRENGTH fails • Due to substandard condition or type of ladder

1.1.1 Ladders- MISMATCH • In almost 50% of the ladder accidents, mismatch between the activity being undertaken and the tool or method used played a part. e.g. the ladder was too short Arbobesluit art. 7.3 lid1&3 en Art.3.16 lid1.
