Concrete Mixer Guarding: A Key Element of Safety


One of the most important things you can do to protect yourself and your coworkers when working with concrete mixers is to make sure the machinery is properly guarded. This might include installing guards around moving parts, such as the drum and auger, as well as guards around electrical components. Proper guarding can help prevent injuries from contact with moving parts and burns from electrical sparks.

Concrete Mixer Machinery Safety: Tips and Best Practices


In addition to guarding, there are a number of other steps you can take to ensure the safety of your concrete mixer:


  • Follow the manufacturer’s instructions for safe operation. This includes reading and understanding the operator’s manual and adhering to any warning labels or cautionary notes.
  • Wear appropriate personal protective equipment (PPE), such as safety glasses, earplugs, and protective clothing.
  • Keep the work area clean and organized. Clutter and debris can create tripping hazards and make it more difficult to move around safely.
  • Use caution when working near the drum. The drum can be heavy and can cause serious injuries if it falls or rolls.
  • Keep your hands and feet clear of moving parts. This includes the drum, auger, and any other moving components.
  • Use only approved attachments and accessories. Using non-approved attachments or accessories can compromise the safety of the machinery and increase the risk of injury.
  • Inspect the concrete mixer regularly for wear and tear. If you notice any problems, such as damaged guards or worn-out parts, address them immediately to prevent accidents.

Making Your Concrete Mixer Safe: The Role of Interlocks


Interlocks are devices that prevent the operation of a machine unless certain conditions are met. For example, an interlock might prevent the operation of a concrete mixer unless the guard is in place. By using interlocks, you can help ensure that safety protocols are followed and reduce the risk of accidents.

Stop Concrete Mixer Accidents: Statistics and Prevention


According to OSHA, the construction industry has one of the highest rates of injuries and fatalities of any sector. While concrete mixers themselves may not be the most hazardous type of machinery on a construction site, they can still pose a risk to workers. In 2018, there were approximately 10,000 injuries involving construction machinery, with concrete mixers accounting for a significant portion of these accidents.


Some common hazards associated with concrete mixers include:


  • Contact with moving parts, such as the drum and auger, which can cause crushing injuries or amputations
  • Burns from electrical sparks or hot surfaces
  • Falls, slips, and trips, especially if the work area is cluttered or poorly lit
  • Noise-induced hearing loss, if earplugs or other hearing protection is not worn
  • Respiratory problems, if dust and other particles are inhaled
  • To prevent accidents involving concrete mixers, it’s important to follow the safety tips and best practices outlined above, as well as any relevant safety standards. By taking these precautions, you can help keep yourself and your coworkers safe on the job site.
