Separate first aid assessments would be required at each worksite because each site may have a different number of workers present, and a different distance to/from an ambulance station.
To determine the workplace class for that site, a first aid assessment must be conducted. The second part of an employer’s 2-part duty is to determine and list any additional first aid services that may be required at that site – this would be documented on page 4 of the First Aid Assessment Worksheet.
