DISPENSING SOLUTIONS
When it comes to dispensing chemicals, it’s easy for things to go wrong in a multitude of ways.
Here, RD Industries aims to solve six of the most common chemical problems in dispensing.
The impact of an inadequate chemical dispensing system can be costly to a company in a variety of ways:
• Incorrect dilution rates result in poor disinfection or slippery floors.
• Janitors getting splashed and injured costing lost workdays.
• Disrupted operations. • Contractor termination.
• Fines imposed on facilities for environmental damage or employee injury.
• Distributors or sales reps losing business.
• Losing hard-won customers, not to mention damage to reputation and your brand.
A systematic approach to implementing a dispensing system assures that common problems are avoided from the start.
1
SPILLS AND LEAKS The most common sign of an inadequate connection
system is a spill or leak. The causes of spills and leaks are inadequate/improperly sized closures, improper seals or connections, improper venting or valve failure. The effects can be very costly ranging from employee injury, damage to assets, product waste or regulatory noncompliance. To solve the problem of spill-prone, leaky containers, properly sized closures that conform to the container opening, allow for proper venting, and positive valve opening and closing are essential.

IMPROPER OR INCONSISTENT DILUTION Dilution errors are often the result of manual dilution,
inadequate closures, an improper metering tip, a clogged metering tip or the loss of the pick-up tube prime due to air leaks. This can result in ineffective cleaning causing health hazards such as infections or outbreaks, damage to assets or destruction of brand reputation. A closure that controls the metering from within the packaging, along with a fresh metering tip in each refill and proper valve connection are critical to produce consistent dilution results.

WRONG PRODUCT USE OR CROSS CONTAMINATION
Accidental mixing of chemicals can have disastrous consequences. Exposure to caustic chemical fumes resulting in employee injury, fines and litigation, damage to assets, product waste and ineffective cleaning are often the result of manual dilution, no color coding, mixing of pick-up tubes during refill change-outs or no mechanical lock-out feature in the dispensing system. A color-coded Closed

Loop dispensing system that includes proper closure on the container leaves little room for error. A proper connection system, including lockouts that prevent erroneous product usage and unauthorized mixing of chemical, is a great line of defense against chemical cross-contamination.

BUILDUP OF POSITIVE OR NEGATIVE PRESSURE When a container closure does not allow for proper
venting, it can collapse during dispensing resulting in improper dilution rates or over-pressurization. This creates the risk of dangerous spills, leaks, spraying or even explosion during shipping. The implications of injury, environmental concerns and exposure to liability are costly. A closure that has the proper venting membrane, which will allow a concentrated chemical to breathe during shipping and storage, reduces the possibility of pressure buildup.
CHEMICAL INCOMPATIBILITY WITH PACKAGING MATERIALS
Failure to correctly match connection materials with chemical concentrate can lead to pricey leaks, spills, chemical exposure, improper dilution rates, product waste and liability issues.
When employing a Closed Loop dispensing system, it must include chemically compatible closure material.

FAILURE TO PROPERLY CONTAIN CONCENTRATES, TO DISPENSE OR CONTROL CONCENTRATES
No container closure, an inadequate/partial loop dispensing system, valve failure or air leaks at connection points counteract proper dispensing. Designing a Closed Loop dispensing system that includes the proper closure on the container along with proper valve connection will prevent improper dilution rates, the potential of dangerous spills and leaks causing employee injury, damage to assets and regulatory noncompliance.
By identifying the areas in which chemical dispensing systems can fail, RD Industries, Inc. can effectively engineer Closed Loop dispensing systems that proactively avoid these common pitfalls.
