Confined space in grain bins and silos safety talk

Entry into feed storage areas such as grain bins and silos may be necessary for a variety of reasons such as maintenance, inspection, cleaning, etc. Entry into a space that was not designated or intended for regular work, has limited or restricted means of entry and exit, or that contains physical hazards is considered a confined space.

Possible feed storage facility confined space hazards:

  • Engulfment from grain, dirt, liquids etc.
  • Explosions from combustible dust created
  • Configuration of the space such as sloping walls and floors
  • Entanglement in moving parts such as shafts, couplings, gears etc.
  • Energy hazards such as heat, electricity, or stored (lockout tagout is required for all energy sources)
  • Noise which can be amplified in a confined space
  • Thermal conditions such as extreme heat or cold

Precautions to take when entering a confined space:

  • Turn off and lock out all powered equipment
  • Employees should never walk on grain to loosen it
  • Employees should never walk under bridging condition
  • Never walk where there is a build-up of grain products on the side that could fall and bury someone
  • Employees entering the space should have on a body harness with a lifeline
  • An observer should be stationed outside the bin/an entry permit should be issued
  • Air should be tested in the bin prior to entry
  • If poor atmosphere is detected necessary ventilation/personal protective equipment should be used
