My recent book :
to Risk Management"
is the outcome of my involvement in the Singapore safety scene over the last many years.

I hope you see this preview of my book as an upload of my hope that you will find it useful and interesting.

A mini-tutorial from the book (p. 39-40, 44-45, 47-50)

This is a mini-tutorial on developing and using a 3 by 3 risk matrix.

It is obvious that the severity of the man's stepping/falling into the drain 50mm, 1m and 2m deep will be 'Low', 'Medium', and 'High' in the respective senses of being acceptable, toler-able, and unacceptable.

Likewise, the likelihood of his not reaching the other bank while trying to cross a 500mm, 1m, and 2m wide drain will be respectively 'Low', 'Medium', and 'High' again in the sense of being acceptable, toler-able, and unacceptable.

Based on this assess-ment of severity and likelihood levels, we may now decide on the risk categories of various combinations of severity and likelihood, as (for instance) indi-cated at the top right corner of each cell: VL - Very Low, L - Low, M - Medium, H - High, and VH - Very High.

(Read the entire book for more on the background, proce-dure, and what to do about the various categories of the risk.)

What is quite intriguing is that within a few months of my developing this example for my book, a 76-year old man (my own age!) who routinely jumped across a 1m wide, 2m deep drain near his house, missed the other edge, and fell ... and died.

(Continued from left column) You will notice from the risk matrix above, that 1m wide and 2m deep drain is rated 'High', but not 'Very High'. Even so, he should not have crossed it.

My example consi-dered a water-filled drain, while the drain that the man crossed was dry, and he hit the bottom ... hard.
