Machinery-Related Amputations


Why is it a priority?

Amputation accounts for 21% of the workplace major injuries from 2014 to 2017 and the number of amputation cases had remain consistently high (Figure 9).  The top two contributing sectors were Manufacturing (34%) and Construction (32%). 39% of amputation injuries involved the use of industrial machines, with sawing machines as the top incident agent.

An analysis of the 660 amputation cases recorded from 2012 to 2016 found that 55% were contributed by unsafe workplace conditions e.g. unguarded machines, use of improper equipment, lack of safe work procedures.  36% of the cases were contributed by unsafe acts e.g. clearing chokes while machine is running or doing last minute adjustments during lifting operation. 

Industry stakeholders who attended a solutioning session organized by WSH Institute in May 2017 had identified the following root causes for amputations:

i. Poor identification of amputation hazards;

ii. Mind-set that accidents will not happen to them;

iii. Unguarded machines; 

iv. Lack of compliance of Safe Work Procedures (SWP); and

v. Ineffective training/briefing.

Research Needs

The following research is needed to reduce workplace accidents resulting in amputations:

  • Determine challenges in preventing amputation injuries and measures to overcome these challenges;
  • Identify different worker or organizational personas and contextualise the solutions for different types of personas;
  • Develop and test solutions to nudge behaviours for prevention of amputation injuries in different industries e.g. Manufacturing, Construction, Marine, Food and Beverage, etc; and
  • Evaluate effectiveness of interventions by measuring workers’ unsafe behavior, near misses, injuries, etc.
