I do not think that falling off a staircase is a trivial risk and if holding handrails is a reasonable mitigation, what is wrong in promoting its use in a constructive way?
There is reasonably decent HSE commisioned research with the title, "Falls on Stairways – Literature Review" highlighting that certain behaviours may influence the likelihood of experiencing a stairway fall
http://www.hse.gov.uk/re...hsl_pdf/2005/hsl0510.pdfAn extract from page 19, Chapter 6 ( Causes of Stairway falls) highlights that:-
"................The use of handrails whilst moving on stairs varies. Pauls (1985) reported use of handrails in
Canadian stairs research as varying between 40% and over 80% for persons within reach of the
handrail and for stairs having one of the following: long flights, steep slopes, distracting views,poor step visibility and crowded conditions. In the Edmonton Commonwealth Games study
(Rhodes et al, 1980 cited in Pauls, 1985), handrails were used by 55% of adults who made up
87% of the sample studied. Handrail technique in ascent commonly involves using a discrete
grip along with a pulling action. For descent, handrail use ranges from sliding or guiding to
discrete grips (Rhodes et al, 1980 cited in Pauls, 1985).............
Obviously there are other factors too.
Carrying items is commonly linked with falls on stairs. Nagata (1991) reported that 24% of victims were
carrying an object at the time of the fall. Carrying items decreases the chance of recovering
from a loss of balance because the hands are not free to grab onto a handrail. The item may be
bulky and obstruct the view of the stairway. The carriage of the item may also alter the balance
of the stairway user which may lead to a fall.
Accidents may occur due to undue haste or rushing. Authors in the stair research field have
commented that rushing when reporting for work or when leaving work is relatively common
(Cohen et al, 1985). This issue can potentially be tackled by employers with training and work
practice reinforcement.
We do it at our site because of its a part of an overall safety culture and our vision of nobody getting hurt akin to the aspirational goal of zero accidents.
