FINGER INJURY

Activity: Handling of concrete blocks.

Scenario: 
While transferring a concrete block (about 40 kg), one worker failed to pass properly the concrete block to his co-worker. What happened is that the concrete block slipped and fell to the ground along with the worker's finger under it. As a result the injured person's left finger was severely crushed and fractured. (See Photo below).



Root Cause:
  1. Shifting and handling of concrete blocks is incorrect.
  2. Failure to follow correct procedure or method of statement.
  3. Not wearing the required PPE (hand gloves) for the given task.
  4. Lack of training and knowledge.


Preventive Measures:
  1. Provide ways to improve lifting, lowering, filling and carrying task by changing work practices by giving training on Manual Material Handling.
  2. Ensure employees use safety gloves when handling heavy objects and/or sharp surface/corners.
  3. Plan for the most effective way possible like using of equipment instead of labor manual handling to reduce the effort and physical force needed to perform work or tasks.


 "Manual handling best practice states physical contact should be considered as a last resort, the use of mechanical means is to be considered. Based on the weight - best practice states it is a two man operation for manual handling if no mechanical means is possible, gloves will help prevent slips but will not protect from crushing.

INJURY FROM ELECTRICAL ARC FLASH

A welder cum fabricator was attempting to plug a twist-lock plug & socket ends extension cord from a 240V, 3 PH disconnect to a welding machine. The plug and cable were both large and the welder/fabricator held the plug and socket ends level at his waist to make the necessary connection. When the connection was made two of the conductors inside the connector got short circuit and cause an arc flash, burning the welder's abdomen (a second degree burn). At the time of the incident the welder was not wearing his PPE (Personal Protective Equipment) properly; the external button-up shirt was completely unbuttoned and shirt-tail out.


PREVENTIVE MEASURES:
  1. All required PPE's must be worn correctly at all times while in the working area.
  2. Inspect all equipment cords, plugs & sockets, electrical components at least monthly and daily before each use.
  3. Evaluate each facility and other related equipment to assess the requirement for hard wiring equipment where temporary wiring is unacceptable to meet the manufacturer's specifications.
  4. Establish a list of qualified and authorized users for each unit/equipment.
  5. Replace all Hubbell Twist-to-lock plug & socket connectors with properly sized and non-conductive connectors. It shall be performed only by a qualified electrician.
  6. Provide instruction to all authorized users of equipment that all electrical connections must be made with the power "SWITCH OFF" or power source to be LOCKED OUT.
