Clandestine Lab Indicators 
 
Clandestine Laboratory 
Clandestine laboratories are illicit operations consisting of apparatuses and chemicals used in the production of a controlled substance.
 
A clandestine laboratory can be very sophisticated in nature or very primitive in its construction (i.e. addiction-based labs). In either case, clandestine laboratories are very dangerous and volatile to anyone in the vicinity.
 
Clandestine Laboratory Indicators:
 
Clandestine laboratories can be located in any environment, ranging from an elaborate industrial setup to small, mobile, 'suitcase' operations. These labs can be located in rural or urban areas or anywhere detection is difficult.
 
The following Clandestine Laboratory Indicators are provided by the Halton Regional Police Service Integrated Drug, Gun and Gang Unit to help members of the public identify such operations in their neighbourhoods.
 
You are reminded not to put yourself in any compromising position to obtain information about a clandestine laboratory or other criminal activity.
