Alert Advisory: Worker caught in between moving machinery and wall

Ref: 1819085 WSH Alert Accident Notification dated 18 February 2019
On 17 January 2019 around 8.40am, a worker walking to his work area was caught in between a moving rail-guided ladle car and the wall along its tracks. The worker was pronounced dead at the scene by attending paramedics.

Recommendations

Caught-in or caught-between accidents occur when a worker’s body part is caught, crushed, squeezed, compressed or pinched between two or more objects. Persons in control of workplaces that present such a hazard should consider the following risk control measures to prevent similar accidents:
Workplace layout

• Perform a site walkabout to identify work areas that may pose a caught-in or
caught-between hazard.
• Adjust the workplace layout to ensure that enough space is provided around
machines or process units to allow for normal operation, adjustments and
ordinary repairs, and for storage of materials.For more information on workplace layout, refer to Singapore Standard SS 567: 2011 for Factory Layout – Safety, Health and Welfare Considerations.
Access to work area

• Provide workers with a safe means of access to and egress from their work area.
In particular, ensure that:
   – passageways between machines, installations (including walls) or piles of
material should be 60 cm or greater (Ref: SS 567: 2011 Section 2.1.6).; and
–  for equipment involving use of tracks/rail, an unobstructed passageway
(on each side of each rail) is maintained parallel to and extended to the entire
length of the tracks/rail.
• If a safe passageway cannot be provided, the access route (e.g. through fencing
or hoarding) should be closed and signages installed to warn workers of the
hazard zone.
• Ensure workers are briefed on the danger of being caught in between a moving
equipment and the surrounding installations should they decide not to use
the designated access or egress route.
Workplace lighting

• Provide adequate lighting along all access routes and at areas where work is to
be carried out. Adequate lighting will help to raise workers’ situational
awareness and enable them to better identify workplace hazards.
• Avoid lighting that is too bright to minimise glare and reflection. It is better to
provide multiple low-strength lights to cover an area, than a single bright light
source.
• Ensure uniform lighting across the work area. Large contrast in brightness when
moving from one place to another will put a strain on workers’ eyes (due to
continual adjustment between bright and dark areas).
For more information on workplace lighting, refer to Singapore Standard SS 531-1: 2006 (2013) Code of Practice for Lighting of Work Places – Indoor and SS 531-2: 2008 (2014) Code of Practice for Lighting of Work Places – Outdoor.
Work supervision

• The supervisor (or appointed representative) should walk around the work area
to confirm that there is no person or obstruction in the vicinity prior to all
movement of machine or equipment. This practice should be clearly documented
in the safe work procedure and emphasized during daily toolbox meetings.
• Work supervision includes supervision of on-site work undertaken by contractors
and subcontractors. All contractors and subcontractors will need to work closely
with the occupier to develop site-specific risk assessments and safe work
procedures for the assigned work activities.
Advice for workers

• Be aware of the moving equipment around you and keep a safe distance from
all moving equipment. Never place yourself between a moving equipment and
an immovable structure or stack of materials.
• Proceed with the work only if you are trained for the equipment to be used
and are aware of the hazards of your assigned task so that you can carry out
your work safely.

Risk Assessment

Conduct a thorough Risk Assessment (RA) for all work activities to manage any foreseeable risk that may arise when moving within or across work sites. The RA should cover, but is not limited, to the following:
• The access route for workers to get to or from their designated work
location(s).
• The possibility of workers being caught-in or -between objects along these
access routes during routine (normal) operation and non-routine (e.g.
shut-down maintenance) operation.
• Effectiveness of communication to all workers including contractors and
sub-contractors.
