Use and Service of the Tank
The use and service of a tank will determine the type of tank selected along with the expected service life and service conditions.
The information below supports decisions around design and tank selection.
· We recommend upon delivery that you inspect the tank for any defects or shipping damage. We suggest that you hydro test (water test) your tank system for 24 hours before introduction of chemicals. This verifies that no damage has occurred to fittings during transport and final installation on site. If necessary, remove all test water to prevent reaction with chemical stored.
· Follow chemical manufacture’s “best practices” for product being stored.
· Confirm compatibility of tank, fittings, and gaskets for chemical to be stored before permanent installation. If necessary test the tank, fitting, and gasket materials of construction for compatibility with the specific chemical application.
· Obtain, utilise and retain Material Safety Data Sheets (MSDS) for the chemical stored.
· Do not change chemical being stored unless certain there will be no hazardous chemical reaction.
· Fill vertical tanks only to top of sidewall.
· Prevent over pressurisation of tank during pneumatic or mechanical filling.
· Maintain secondary containment of proper size and chemical resistance to comply with local, state, and National regulations. Protect personnel from possible chemical release.
· Maintain guards, shields, barriers, and walkways to protect tank, fittings, and piping from damage by impact and to protect personnel from chemical release.
· Label tank with the appropriate warning label for the chemical to be stored. Do not remove Bushmans general warning labels. Replace damaged or illegible labels immediately.
· Keep vents and vent lines clear of obstructions to prevent pressure or vacuum.
· Service fume scrubber systems (if used) to prevent tank over pressurisation.
· Accessory items are HEAVY. Use adequate equipment and properly trained personnel when servicing internal fittings and other external accessories.
· Do not stand or work on top of tank. The tank surfaces are flexible and slippery and a dangerous fall could occur. Remember – Safety First
· Tanks are confined spaces. Follow proper entry procedures. Establish an adequate retrieval plan.
· The storage of some chemicals can have an oxidising affect over the longer term on the poly raw material and may require special considerations. As an example, sodium hypochlorite which is a chlorine based bleach or disinfectant will decay due to UV exposure and elevated temperatures. When the degradation occurs, it forms a buildup of sediment in the bottom of the tank. Flushing the tank intermittently will help extend the life of the tank.
· Conduct regular inspections of tank. Refer Bushmans Annual Chemical Tank Inspection Checklist. Look for and address stress cracking, especially on interior surface, worn or leaking fittings and flexible connections, leaking or poorly working valves, restricted vent lines, and needed repairs to other accessories.
WARNING: Failure to adequately support tank, fittings, valves, piping, and hoses and to protect them from impact can cause chemical release resulting in serious injury or death.
