Scaffolding




Proper shotcrete / Concrete applications  are challenging and can be potentially dangerous. The shotcrete nozzle blast is dangerous.
A shotcrete operation requires several high pressure hoses (air, material, water, hydraulic).


Typically, hose ruptures occur at the connections and areas subject to abrasion. Special attention must be given to safety clamping all material hoses and air lines. All pressure lines-air, water and material-should be checked periodically for abrasions. Because of the various high-pressure hazards on shotcrete jobs, all personnel should wear eye protection and suitable clothing.  


Never place hands into the piston or Hopper of a concrete pump. The valves that swing from one piston to the other can quickly and easily cut off a hand or arm. The hopper screen of all concrete pumps must be in place whenever the units are operating to avoid accidents with the rotating agitator or swinging valves.


The unattended nozzle is dangerous. Treat it like a loaded gun. It should not be casually put down until all pressure is off line. Pressure can build up in hose due to a plug in the line and temporarily stop the flow of material out of the nozzle. When the pump stops, the pressure in the line is not necessarily relieved. 


Shotcrete operations usually require scaffolding so that the nozzleman can properly and safely place the shotcrete. Scaffolding to provide a safe working platform must be secure and large enough to allow personnel movement. Scaffolding should provide a back brace for the nozzleman to counteract the nozzle thrust.

  • Wear alkali-resistant gloves, coveralls with long sleeves and full length pants, water proof boots and eye protection. 
  • Wash contaminated skin area with cold, running water as soon as possible. 
  • Rinse eyes splashed with wet shotcrete with water for at least 15 minutes and then go to the hospital for further treatment. 


Concrete Overspray / Dust Hazard:

Exposure to cement dust can irritate eyes, nose, throat and upper respiratory system. Skin contact may result in moderate irritation to thickening/cracking of skin to severe skin damage from chemical burns. Silica exposure can lead to lung injuries always wear protection

  • Rinse eyes with water if they come into contact with cement dust and consult a physician. 
  • Use soap and water to wash off dust to avoid skin damage. 
  • Wear a P-,N, OR R-95 respirator to minimize inhalation of cement dust. 
  • Eat and drink only in dust-free areas to avoid ingesting cement dust.
