First aid kits must be complete and maintained according to the prevailing laws, and readily accessible at all permanent facilities and buildings. Portable first aid kits must be transported to the production units where workers are working. (AF 3.4.4)
Inspectors are required to verify that the appropriate number of persons (guideline: one trained person per 50 workers) trained in First Aid (within the last 5 years) is always available when activities are taking place on the farm. (AF 3.4.5)
GLOBALG.A.P. states as a guideline that 1 first aider is needed for every 50 workers a producer employs and that this person must be present on the farm whenever on-farm activities (e.g. in this case harvesting) are being carried out. If there is only 1 trained first aider, back-up plans must be in place for the days when the first aider is absent.
GLOBALG.A.P. requires that there must always be a sufficient number of trained (at least every 5 years) first aiders on the farm when on-farm activities are being carried out. The problem with the qualified nurse is that she is not always available during on-farm activities.
