- - - - Increased injury rates
        
        Reduced productivity
        
        Fatigue
        
        Worker dissatisfaction
        
        Higher error rates
    - - Human (worker)
        
        Strength
        
        Endurance
        
        Anthropometry

        Motivation
        
        Work capacity
        
        Must also consider mental workload
        eg switching off from work, taking work home, under stimulation at work
        
        If effort is too great = mental strain
      - Machine/Task
        
        Postural demands
        
        Rest periods

        Chemical
        
        Radiation
        
        Effects of noise
        
        Can affect health and performance at work
        
        Health = increased stress, headaches, noise induced hearing loss
        
        Performance = reduced productivity, decreased alertness
