Any leaks in the areas surrounding the equipment may cause personnel to slip.

Check that there are no leaks and keep these areas clean at all times.

2.3.5 Tripping

Generally untidy deposits of material may constitute a tripping hazard and a total or partial 

obstruction of emergency exit routes.

You should ensure that operating and transit areas and emergency exit routes are free from 

obstacles in compliance with current legislation.
