02Jun

After feeding aggregate, sand and other materials, mixing process and delivering the composite materials, we should clean and depart the jobsite. Such as cleaning concrete mixer drum and other position.

There are some dangerous position, the cleaners are not there
Plugging hazard. Do not wash out the mixer truck into the pump hopper. Water washes the cement and fine aggregate out of the mix, leaving a coarse mixture that cannot be pumped (called segregation).
Hose whipping and projectile hazard. At the end of the job, the operator may want the level of material in the hopper to be lower than usual. In spite of this, do not allow the level to become so low that air is sucked into the material cylinders.
Collision hazard. Do not drive under the boom of the concrete pump when pulling away from the job. Have the operator move the boom to a safe area, or take a different route off the jobsite.
Falling and hose whipping hazard. If the pump operator is going to empty the hopper into your mixer truck, let him maneuver the end hose in with the boom. Do not try to help by directing it in with your hands. Kinking the hose can lead to serious injury.
Various hazards. If the concrete is being pumped back into the mixer truck, stay away from the hopper, or sit in the cab of your truck until it’s done.
Hose whipping and projectile hazard. Make sure the operator knows you’re empty and leaving. Be friendly; before leaving, if you have spare water, see if the pump operator needs it.
Crushing hazard. Be sure all personnel are at a safe distance from the mixer truck before pulling away from the pump.

During concrete mixer truck and concrete pumps application, I think the Recommended Handsignals are important to lead the operator in right direction.

So I suggest that whatever you drive, you should operating or working according to specifications, these maximum possible to protect yourself.
