IAQ Concerns Resulting From Fluid Dispensing

Fluid dispensing for the creation and assembly of goods is a necessary practice used in industries far and wide. From the conductive adhesives applied to the smallest printed circuit board to the solder pastes used in joining large airplane parts, fluid dispensing is performed every day for industrial assembly, lubrication, sealing, and coating.

Like many industrial practices, fluid dispensing can pose air quality problems due to pollutants released into the surrounding environment. Persons most at risk from these emissions are the workers directly involved with the dispensing process.

Fluid Dispensing Defined

In an industrial setting, fluid dispensing refers to delivering controlled amounts of liquid to apply specialized fluids such as lubricants, sealants, and solvents with accuracy and precision. Often, products demand automated repetition.

Fluid dispensing systems can range from simple handheld devices to complex automated robots, depending on the application and form of fluid being used. Systems usually fall into one of three categories:

Manual – where syringes, squeeze bottles, or other handheld tools are used for dispensing small amounts of fluid.

Semi-automated – have manual controls for otherwise automated systems. Benefits include adjustable flow rates and hands-free activation.

Fully automated – these systems contain programmed dispensing patterns with integrated and programmable controls and specialized dispensing, such as robotic arms. Ideal for high-volume, high-speed, and high-precision applications.

Fluid Dispensing Industries & Applications

In addition to the types of fluids mentioned earlier, are TIMs (Thermal Interface Materials) used to dissipate heat in electronics, as well as coatings, which are applied for embellishment or protection.

Examples of industries that need fluid dispensing to manufacture their products include:

Automotive – for coatings and parts fabrication

Biotech – for surgical fluid management

Chemical – for ensuring proper volume of cleaning, sanitizing, and disinfectant products

Electronic – for component assembly, semiconductor protection

Medical – for implants, diagnostic equipment, and pharmaceuticals

Indoor Air Quality Risks

The types of fluid dispensing systems that pose the most concerning IAQ risks are open and semi-closed systems during the transfer stage, at the point when drips and leaks can cause airborne fumes and vapors. 

The types of emissions that cause occupational risk include:

  1. Volatile Organic Compounds (VOCs): Many industrial fluids contain VOCs. These substances can cause a range of health complications, such as headaches, vertigo, and eye, nose, and throat irritation. Some studies indicate they can cause cancer.
  2. Hazardous Air Pollutants (HAPs): Certain industrial fluids may contain specific toxins that pose significant health risks if inhaled. Toluene and benzene are just two types that can lead to illness depending on the amount and duration of exposure. 
  3. Particulate Matter (PM): Some dispensing processes can generate dust, aerosols, and other airborne particles. Respirable particles can penetrate deep into the lungs and cause respiratory damage.
  4. Chemicals (other): Depending on the fluid being dispensed, other pollutants might be released, such as sulfur dioxide, nitrogen oxides, carbon monoxide, or other chemical fumes. 

Air Quality Solutions

To avoid chronic exposure to fluid dispensing emissions in the workplace, manufacturers should protect their workforce and indoor environment by:

  1. Requiring the use of PPE (personal protective equipment) such as gloves, masks, and goggles for all employees
  2. Keeping work areas clean and dust-free
  3. Implementing proper engineering controls such as proper ventilation
  4. Substituting less hazardous fluid alternatives when possible
  5. Removing fumes, dust, and particles at the source using a dust-collecting air filtration cleaner

Manufacturers have long been aware of the need for clean air in the workplace: worker health, product quality, regulatory compliance, and enhanced productivity are all central to their bottom line.  The companies that go the furthest in air pollution prevention are those that incorporate air filtration into their workplace safety programs.

Our air filtration systems are prized for their ability to remove chemicals, dust, and particulates from any production facility, ensuring the highest level of clean air. 

At AIRSInc., we have the experience, depth of knowledge, and superior products to protect our customers and their employees from the threat of indoor air pollution. Contact us today for a free air quality assessment with one of our skilled and experienced specialists.
