Lock prevents manufacture of crystal meth

Smith Flow Control product story

Smith Flow Control (SFC) is helping to eliminate methamphetamine (crystal meth) labs in Iowa and across the United States by cutting off the illegal supply of its primary ingredient.
Anhydrous ammonia (NH3), a fertiliser stored in large nurse tanks on farms, is often stolen to manufacture crystal meth in home labs.
SFC's Tanks-A-Lok is locking off ammonia storage tanks on farmland to prevent unauthorised access and theft.
All 24,000 NH3 tanks in Iowa have been locked off using Tanks-A-Lok, virtually eliminating meth labs in the state.
It is hoped nurse tanks in other US states will be secured with Tanks-A-Lok.
Tanks-A-Lok locks are made of hardened steel and three models are available to fit the host valve.
Inserting the correct coded key allows access to the valve.
The lock is resistant to any other attempts to remove it and, once secured, nurse tanks can be left unattended.
The World Health Organisation says crystal meth abuse worldwide is worse than heroin and cocaine combined.
