Man/Machine Interface – Spotters

We continue our Man/Machine Interface series by taking a closer look at the use of Spotters when working around machines and heavy equipment.

Last week, we talked about how blind spots are an inherent danger when operating certain vehicles and equipment. This week we’ll focus on the role of a Spotter – a key component to safe operations when dealing with blind spots & excavation work. When use of a spotter is necessary, Spotters & Equipment Operators should work in partnership and keep the following in mind:

  • Discuss the positioning, backing, movement & means of communication (hand-signals) prior to beginning work. Spotters & Operators shall have a clear understanding of signal protocol and be competent in directing and signaling equipment.
  • Spotters & Operators should discuss at what point the Spotters duties will no longer be necessary (e.g. when the operator has exited the equipment; when the vehicle is positioned to only move in a forward direction, etc.).
  • Spotters & Operators should always be visible to each other.  If an Operator loses sight of a Spotter, the operation should cease immediately. Spotters shall wear bright, reflective clothing.
  • Spotters shall not be in the path of equipment travel while equipment is backing into a dump or loading area.
  • If a signal is unclear, operation should immediately stop.  Operators should never guess what a signal means.
  • Spotting is the only duty a Spotter has.  Distractions should be avoided and a Spotter should refrain from using a cellphone, texting or any other communications not related to the spotting duties. If the attention of a Spotter is diverted from their spotting duties, operations shall stop.
  • Spotters shall be used for all excavations within10-foot (3-meters) of underground utilities.
  • While a Spotter is busy looking out for the safety of others, they should also remember to keep their own safety in mind.  Conduct a “Circle of Safety” walk and survey the work area for tripping hazards, equipment components & attachments and other hazards that may be present in the area they will be standing and working.  Also, don’t forget to “look-up” for overhead hazards.

Due to the nature of our work and the equipment and machines we use, blind spots are a risk we often face.  Good planning and communication of role responsibilities between Operators & Spotters can help to minimize that risk.
