Accident Advisory: Worker struck by falling objects at warehouse 

Ref: 1920078 WSH Alert Accident Notification dated 24 December 2019
On 23 December 2019, a worker was found on the floor of a warehouse with goods around him. It was likely that some pallets of goods had toppled and struck the worker. The worker succumbed to his injuries at the scene.
                               Figure 1: Overview of the accident scene.


Stakeholders such as occupiers, principals, employers and contractors in control of similar workplaces and work activities are advised to consider the following risk control measures to prevent similar accidents:

Safe storage of goods
Ensure the safe storage, access and retrieval of goods in proper storage
   areas (e.g. warehouses or storerooms).
• Consider the use of engineered storage racks where appropriate. The use of
   engineered rack systems that are properly assembled and securely installed
   (e.g. anchored to the floor and/or ceiling with tie-backs to adjacent wall(s))
   is recommended as it will offer improved structural stability. 

Recommended practice (non-exhaustive) for safe use of storage racks:
     – Store heavier objects on lower shelves for additional rack stability.
     – Place goods that are frequently retrieved on the lower shelves for easy
        retrieval and minimise adopting awkward postures.
     – Goods placed on pallets should be stretch-wrapped to prevent them from falling
        off the pallet.
     – Loose items should be tied together, shrink-wrapped or kept in containers to
       prevent unwanted movement.
     – Regularly inspect storage racks to ensure that they are in good condition
       (e.g. no signs of damage or corrosion) and stable.

• Establish and implement a Safe Work Procedure (SWP) for safe storage and
   retrieval of goods.
• Display the Safe Working Load (SWL) for each shelf of the storage rack. Goods
   should be weighed prior to placement on the rack and checks carried out to ensure
   that the SWL of the shelf is not exceeded.

• Stack goods such that the load is evenly distributed on the shelf of the storage rack.
   This is important as uneven loading can affect the stability of the racking system.
• Ensure that workers are trained on the SWP for transferring goods to and from
   the storage racks. Train workers on the use of a mechanical aid (e.g. forklift or
   reach truck).

• For manual retrieval, advise workers to seek assistance from a fellow worker if
   the item to be retrieved is heavy or bulky.
• Carefully assess the need for stacking palletised load as stacked loads may be
   unstable and pose a toppling risk. The total weight of the stacked goods must
   never exceed the SWL of the lower pallet, which must bear
   the weight of the goods placed on it plus the weight of the upper stack.
Safe storage area
Survey storage areas prior to moving goods to identify hazards that could arise
   due to poor housekeeping, the use of pallets in poor condition and the presence
   of stacked or loose objects that could topple or fall.
• Provide a clear and safe path of access from the entrance of the storage area to
   the storage racks. The floor of the storage area should be kept free of hazards
   that could result in a slip, trip or fall.
• Provide adequate workplace lighting and ventilation to facilitate safe work within
   the storage area.
Worker monitoring
The whereabouts of workers should be monitored, especially those who have to
   work alone or after office hours. Tracking methods may include signing in at key
   work locations or checkpoints, regular check-in via radio communications,
   monitoring via closed-circuit television, and use of Global Positioning System
   to indicate worker location. Monitoring will allow employers to respond
   quickly should an emergency arise.

Risk Assessment

Conduct a thorough Risk Assessment (RA) for all work activities to manage any foreseeable risk that may arise for work in storage areas. The RA should include, but not limited to, the following areas:

• Possibility of stacked goods toppling
• Workplace housekeeping
• Manual handling of goods
