Blackwell’s, Inc. continues with Covid-19 preparedness and prevention readiness.

Our protocol initially established on March 7, 2020, has been modified to reflect updated CDC guidelines and information about the virus. Modifications will continue as more information becomes known. Blackwell’s has purchased additional foggers, and EPA approved sanitization chemicals have been stockpiled by our company to prevent availability service disruptions from impacting clientele. Duct cleaning and duct sanitizing equipment modifications make our duct cleaning process even more effective in removing particulate attachment media within ducts. Fumigation of ductwork interior surfaces have also been enhanced both mechanically and chemically. The economical chemical fogging process we are using allows our customers to re-occupy sanitized space within 45 minutes of application. This is based on good air movement. The fogging process is literally a slow walk through the area. Please know, we are here to help you continue to work safely and productively. Keep Blackwell’s, Inc. in mind should the need arise. We will all get through this if we continue to work together.

Cleaning ovens and ductwork

HVAC and Ductwork Cleaning:

  • Initial cleaning to remove debris
  • Ductwork systems fogged with sanitizer registered by the EPA specifically for ductwork
  • Common areas, frequently touched hard, non-porous surfaces, and walls typically up to 8 ft. or above, are treated with EPA approved germicidal disinfectant.

Food Processing Facilities:

Walls and hard surfaces in food handling and processing areas in schools, dairies, restaurants, and USDA inspected facilities, are treated with sanitizer approved by the EPA for these areas.

Procedures to Contain the Virus:

  • Staging and decontamination for our cleaning and sanitizing teams take place in negative pressure containment areas
  • Cleaned and sanitized areas are barricaded and posted with re-entry times to prevent re-introducing contamination to these areas
We will continue to monitor the Centers for Disease Control and the Environmental Protection Agency guidelines, in a front-line position in the fight against Covid-19.

Regardless of what a silo holds, there will come a time when it will have to be cleaned.

Cleaning is necessary to:
  • Remove the buildup of old product that reduces the volume of the silo
  • Dislodge wall or cone buildup that impedes the flow of product to the auger or pneumatic conveyance and increases the likely hood of “bridging”
  • Allow for inspection of the silo to determine areas needing repair
  • Control sources of contaminants in the silo
  • Help prevent insect infestation
Dangers associated with the confined space cleaning of silos:
  • Falls resulting from the use of inadequate safety equipment and/or training in the use of the equipment
  • Spontaneous combustion due to suspended particulate matter
  • Depleted oxygen levels and/or noxious gases
  • Entrapment in the product due to voids created from product “bridging” in the silo and the potential collapse of the product.
The advantages of blast cleaning food silos with CO2 instead of pressure washing:
  • Mold growth is inhibited because no water is used
  • Silo surfaces are decontaminated
  • No secondary waste stream-food silo residues can be removed by vacuum

Silo Interior Lining Repair Lining

Drastic measures are sometimes needed to prevent contamination of the finished product in silos. Even when design specifications are followed during construction, inspections of an aging silo can uncover a lining failure of the wall that can cause the product in the silo to be unfit for its intended use. A repair of the wall lining is especially important in a food product silo. Scope of Work to Repair a Food Silo Lining
  • Follow all confined space protocol using Blackwell’s, Inc. OSHA certified associates
  • Remove any remaining product to allow for inspection of the silo to determine areas needing repair (Vacuum truck available if needed)
  • Construct a negative air barricade to prevent cross-contamination (if inside a facility)
  • Use hot water/high pressure wash cleaning of interior walls
  • Collect and dispose of liquid waste effluent from the pressure washing
  • Mechanically hand grind the coating failure areas to SSPC specifications
  • Apply a FDA approved penetrating epoxy primer to prevent flash rusting
  • Apply a 100% solids coating material for steel creating a suitable wear and bond coat
  • Apply FDA approved high performance and abrasive resistant tank lining.
  • A final hot water/high pressure washing and drying completes the repair

Manufacturing typically creates all kinds of dust, smoke, mists, or any number of different particulates.

These contaminants are removed from the manufacturing facility through an exhaust system which ideally filters the exhaust air before it is released back into the atmosphere. Over time, these contaminants can buildup in the exhaust ductwork itself.

For plants in continuous production, these systems require preventive maintenance.

Problems associated with contaminant buildup in the ductwork and air handlers:

  • Restriction of air flow
  • Risk of fire hazard
  • Illness from breathing contaminated plant air
  • Contaminants being released into atmosphere

These problems affect the system by:

  • Increasing maintenance costs
  • Increasing the frequency of shutdowns for repair and/or replacement of components
  • Decreasing the efficiency of the system and increasing energy consumption
  • Posing a potential liability associated with illness due breathing contaminated plant air
  • Environmental liability due to release of contaminated air

When it comes to keeping your business clean, walls and ceilings are commonly missed.

Don't overlook these key surfaces in your industrial business. Schedule a cleaning of your walls and ceilings to create a smooth, functional workspace. Our team is trained and certified to clean your industrial surfaces, no matter what type of industry you're in.  

Call Blackwell's for all your pressure washing needs.

Our high-tech equipment can get even the roughest surfaces clean. You know how important it is to keep your industrial space clean, let us do the dirty work so you can get back to business.

25% of confined spaces have hazardous air. 50% of deaths in confined spaces result from oxygen deficiency and no air monitoring.

OSHA defines a confined space as any space that:
  • Is large enough that an employee can enter and perform work
  • Has limited or restricted means for entry or exit
  • Is not designed for continuous employee occupancy
OSHA Permit-required Confined Space:
  • Contains or may contain a hazardous atmosphere
  • Contains a material that has the potential for engulfing an entrant
  • Is shaped such that an entrant could be trapped or asphyxiated
  • Contains any other serious safety or health hazards
When we send one of our Blackwell’s associates into a confined space, we monitor the air continuously, and we send someone that's OSHA trained to work in tight, dangerous places. Not only is the associate trained and equipped with all the equipment he needs to keep him safe, but he has an OSHA trained support crew topside to get him out safely if an accident happens.

Cooling towers are specialized heat exchanging devices to cool water and dissipate heat to the atmosphere.

For plants in continuous production, these systems require preventive maintenance.

Problems associated with cooling water systems:

  • Corrosion from oxidation of the metal components of system
  • Scale buildup from precipitation of minerals in water
  • Fouling from dust and corrosion by-products
  • Microbial contamination (bacteria, yeasts, fungi, algae) creating waste deposits (microbial slime) and potential contagions (e.g. Legionella)
  • Animal excrement buildup (e.g. pigeons) and disease associated with atomization and respiration of contaminated water

These problems affect the system by:

  • Increasing maintenance costs
  • Increasing the frequency of shutdowns for repair and/or replacement of components
  • Decreasing the cooling efficiency and increasing energy consumption
  • Posing a potential liability associated with illness due to lack of cleaning or maintenance of the cooling tower
