ecoFridge uses a completely ‘fail safe’ system to ensure that operatives cannot compromise their safety in any way. Nitrogen (which is non-toxic and makes up around 80% of the earth’s atmosphere) is released as a refrigerant into the trailer’s loading area only when the doors are closed. Should an operative become enclosed in the load space, an independently powered, illuminated press-button will instantly close the system down.

As soon as the doors are opened, the O2 analyser and warning system automatically checks the internal atmosphere and will not allow entry until the requisite O2 level is achieved:

• Each compartment has an independently powered O2 analyser and
  warning system
  
• System safety is computer controlled
  
• Using ecoFridge bulkheads, the temperature will remain constant in the
  front section while operatives can work in the remaining load space
  
• Cable and bulkhead locks prevent access to load spaces until venting
  is complete.
  
• Audible and visual alerts advise operator when load space is ready for access.
