O'Toole Inc. - Executive Summary

O?Toole Inc submits this Risk Management Plan as an ongoing effort to maintain the safety and confidence which our 
community has placed with us to coexist safely within the neighborhood.  We strive to keep all storage and mobile 
equipment up to the latest state codes.  Our facility is inspected by the Iowa Department of Agriculture at the 
minimum of once a year and sometimes twice. As a part of  our continuing effort to maintain safety we change all 
pressure relief valves when the dates stamped on them by the manufacturers expire. These valves are all stamped with 
the date of manufacture ,the expiration date & flow capacity. There are no shutoff valves between these reliefs and 
the tank. These valves act to keep the pressures in the storage facility well under the designed strength of the tank.  
They are set to relieve the pressure at 250psi.and there are 4 of them on the storage tank.  The design test pressure of 
the storage tank is 375psi at 115 degrees F.  Pressure in the storage ta 
nk is monitored by an external 0-400 psi gauge 
on the dial end of the tank.  The shell thickness of our tank is 15/16? thick and the ends are over 1/2? thick.  The 
storage tank is built to 1965 AMSE code Sec II,VII,Ix Par UWSI with 5 pc. head beads spot x-rayed per Par 
UW52A.  The tank was also heat treated per Par UW40&UCS56.  It was manufactured in Memphis Tennessee 
especially for anhydrous ammonia use by Flint Steel Corporation and inspected by a commissioned inspector of the 
National Board of Boiler & Pressure Vessel Inspectors of the state of Tennessee.  All outlets of  the tank vapor and 
liquid contain excess flow valves which are spring loaded .  These valves function  if a pipe were to be compromised 
the flow of ammonia would close these valves thus preventing a massive outflow of ammonia.  The storage tank is 
located 60? from our water supply.  All plumbing on the storage facility was professionally installed by Dales 
Petroleum Service of Fort Dodge Ia.  All piping is schedule 
80 and rated for anhydrous ammonia and protected from 
traffic by two cement filled pillars 4 foot in the ground.  Safety measures included in the plumbing include hydrostatic 
relief valves which are placed anywhere in the system which ammonia is confined between two valves with no place 
to escape.  These valves will vent the pressure in these pipes to prevent pipe failure.  Other safety measures include a 
cable operated shutoff valve which can be accessed at the opposite end of the tank from all other plumbing this valve 
was installed after the plant was built as soon as they became available.  The pump itself can be shutoff at 4 locations 
within the plant site.  The pump is equipped with a 0-400psi pressure gauge on the pressure side and a bypass line 
which returns product to the suction side of the pump.   
Hoses on the loading dock are all rated for anhydrous ammonia and carry dates of manufacture and pressure ratings 
stamped at a minimum of every 5 foot intervals for the length o 
f hose.  These hoses are replaced on or before their 
stamped expiration dates.  Where these hoses connect to plant piping special breakaway valves are installed which are 
designed to uncouple in the event of someone driving away while hoses are still connected with a loss of less than 1 
oz. of liquid anhydrous being released. In addition the hoses are protected by hydrostatic relief valves to keep trapped  
ammonia from building pressures over their rated capacity.  Ends of hoses are hung in lockable racks which prevents 
unauthorized access. 
O?Toole Inc. has annual training for employees for the safety and handling of anhydrous ammonia. They are required 
to view a state approved video on the safe handling of anhydrous ammonia which is done on site.  O?Toole Inc keeps 
two anhydrous ammonia gas masks on site with anhydrous ammonia rated canisters including one extra canister for 
each mask.  The canisters are replaced on or before the  expiration date stamped on them by the  manufacturer. 
Employees are trained not to fill any nurse tanks or the storage tank to over 85% full at any time.  During any transfer 
of anhydrous there is always an employee present. O?Toole Inc. maintains 2 water tanks located in transfer areas for 
load-in and load -out operations and also has a shower in the office nearby for any exposure to anhydrous needing 
water applied immediately.  Goggles and gloves are furnished for all employees and growers free of charge and are 
required apparel during transfer operations.  The Letts Fire Department has been on site for instruction on how to 
shutoff pumps and to the basic operation of the plant .  Each year the facility undergoes a checklist inspection of all 
hoses,relief valves,guages,and all other safety related equipment.  These safeguards and preventive maintenance are 
all in an all out effort by O?Toole to be as safe as humanly possible.The source of the  regulated substance which is anhyrous ammonia is the 30000 gal. tank located on the north si 
de of the office& 35 nurse tanks located throughout the property.There have been no reportable accidents or releases in the last 5 years.The emergency respose plan for O'Toole Inc.In the  event of a major release of anhydrous ammonia report to facility personel,Louisa County Emergency planning Comittee chairperson at 319-523-4371.Louisa Co. sheriffs dept& Letts Fire Dept at 911.If evacuation deemed necessary by facility manager& authorities also notifyKWPC radio at 319-263-8600.Also call neighbors,Dave Crull at 726-4188,Harry Black at 726-5021,Terry Peterson at 726-3801,Louise Padgett at 726-3731,Ron Shuler at 726-5107,Belinda Crossley at 726-4412,Kevin Clevenger at 726-3500,Dick Clevenger at 726-3502,Cristy Padgett at 726-3069.
