INFO ALERT:  21  
  
DATE:  July 17, 1992  
  
  
*** HAZARD SUMMARY:  ***  POTENTIAL HAZARDS - DOUGH MIXERS  
  
In recent months, a significant number of orders for the guarding of dough  
mixers have been issued.  Injuries from these machines are generally caused by  
exposed moving parts such as whisks, paddles, hooks or other blending  
accessories.  Access to these parts may result in crushing, laceration or  
fracture injuries to the hands and arms.  
  
*** LOCATION(S) AND SECTOR(S) WHERE HAZARD MAY BE ENCOUNTERED ***  
  
Bakeries, restaurants, supermarkets, hotels, theme parks, colleges and  
schools.  
  
*** SUGGESTED PRECAUTIONS AND APPLICABLE SECTION(S) OF INDUSTRIAL REGULATIONS *
*  
  
Accidents of this type can be avoided by ensuring that dough mixing machines  
are properly guarded to effectively prevent worker access to the moving parts  
of the machine.  The guard should be interlocked to prevent operation of the  
equipment when the guard is opened for pouring or cleaning, or when the bowl is 
lowered.  This interlock shall not be used in place of an appropriate lock-out  
procedure.  Further to this, the worker shall be trained to recognize the  
possible hazards as required under the Occupational Health and Safety Act.  
  
The Regulations for Industrial Establishments state:  
  
Under Section 28  
  
    "Where a machine or prime mover or transmission equipment has an exposed  
    moving part that may endanger the safety of any worker, the machine or  
    prime mover or transmission equipment shall be equipped with and guarded  
    by a guard or other device that prevents access to the moving part."
