Established criteria giving early warning of potential drift from normal conditions which are not necessarily grounds for definitive corrective action, but which require follow-up investigation. These limits are like a barrier before the final action limits, given by different regulatory agencies. We have to be alert if the microbial count reaches this alert level. It is not necessary to take any action when the count reaches to alert limit level but we have to be alert as this is a trigger that something is going wrong within the environment and microbial contamination is increasing in the area.
