What is OSHA?

Upwards of 90 million people in the US are spending their days on the job. As a nation, they’re our most important resource. And shockingly up until 1970, there were no unified and concise requirements available for safety in the workplace and their protection against health risks.

How did OSHA Form?

In 1970, Congress took into consideration annual figures like these:

  • Job-related accidents took into account for more than 14,000 worker deaths.
  • Almost 2 1/2 million workers had been disabled.
  • 10 times as many person-days were missed from occupational disabilities as from strikes.
  • Approximated new cases of job-related diseases reached 300,000

Regarding lost production and income, compensation for disability and expenses, medical, the burden on the nation’s commerce was astounding. The human cost was outside calculations. Consequently, the Occupational Safety and Health Act of 1979 was passed by both parties of Congress “…to assure so far as possible every working man and woman in the Nation safe and healthful working conditions and to preserve our human resources.”

What does OSHA Stand For?

Under Congress’ Act, the Occupational Safety and Health Administration (OSHA) was developed under the Department of Labor.

In simple terms, OSHA is the Occupational Safety and Health Administration and its responsibility for worker safety and health safeguarding.

Since its creation in 1970, OSHA has reduced the work fatality rate in excess of half, decreased the general injury and illness rates in industries that OSHA has focused its attention, practically eliminated brown lung disease in textile industries and decreased excavation and trenching deaths by 35%.

OSHA is managed through the Department of Labor (DOL). The Department of Labor regulates and enforces in excess of 180 federal laws. These regulations and the mandates that execute them cover a lot of workplace activities for around 10 million employers and their 125 million employees.

Who Does OSHA Cover?

OSHA establishes which standards are applied to your workplace and requires you to comply with these terms and conditions.

Every single employee and their employers under Federal Government jurisdiction are covered by OSHA. Coverage is offered one of two ways, directly by federal OSHA or under state programs. OSHA doesn’t cover self-employed individuals or immediate members of a farm family that don’t employ outside workers.

OSHA provides a comprehensive Website at osha.gov that includes sections dedicated to training, state programs, small business, construction, in addition to interactive eTools to assist employers and their employees.

OSHA also provides training programs to get hazard recognition for employers and their employees. Many states at the moment require training.

Counterflow And Crossflow Cooling Towers

Crossflow Cooling Towers

With a crossflow tower, hot water flows downward from a distribution basin while air flows horizontally. They are filled with splash type fillings and can be applied when water has higher suspended particles. At Industrial Cooling Solutions, we offer crossflow towers in induced draft, forced draft, concrete, FRP, and wood structure as well as splash fill, film fill and low fouling fill materials. ICS cooling towers are built to withstand the most demanding of situations and provide the most cost-effective solution for you.

Benefits:

  • High Performance
  • Low Maintenance
  • Low Noise
  • Optimized Power Consumption

Counterflow Cooling Towers

A counterflow mechanism is one where air flows vertically through the fillings or packing at the top while water flows downward. In a counterflow cooling tower, there is an induced draught fan that is attached to the motor. This fan pulls in air to draft it upward resulting in air that is exhausted faster than it is pulled in. In turn, you’ll see lower pressure and circulation.

Benefits:

  • Low Power Consumption
  • Low Fouling Film or Splash fills
  • Plume Abated Systems
  • Low Pumphead
  • High Performance with Minimal Maintenance
  • Optimized Footprint
  • FRP Wood or Concrete Structures

Reopening Water Cooling Towers After COVID-19

The following is from the Centers For Disease Control and Prevention in reference to Water Cooling Towers re-opening following the COVID-19 virus. The full text may be found here: https://www.cdc.gov/coronavirus/2019-ncov/php/building-water-system.html

Stagnant, or standing water can cause conditions that increase the risk for growth and spread of Legionella and other biofilm-associated bacteria. When water is stagnant, hot water temperatures can decrease to the Legionella growth range (77–108°F, 25–42°C). Stagnant water can also lead to low or undetectable levels of disinfectant, such as chlorine. Ensure that your water system is safe to use after a prolonged shutdown to minimize the risk of Legionnaires’ disease and other diseases associated with water.

Steps To Take

  1. Develop a comprehensive water management program (WMP) for your water system and all devices that use water. Guidance to help with this process is available from CDC and others.
    1. Water Management Program Toolkit:
      This toolkit is designed to help people understand which buildings and devices need a Legionella water management program to reduce the risk of Legionnaires’ disease, what makes a good program, and how to develop it.
      https://www.cdc.gov/legionella/wmp/toolkit/index.html
    2. Preventing Legionnaires’ Disease: A Training on Legionella Water Management Programs (PreventLD Training)
      Take this training from CDC and partners on creating a water management program to reduce risk of Legionnaires’ disease. PreventLD Training aligns with industry standards on managing risk of Legionella bacteria.
      https://www.cdc.gov/nceh/ehs/elearn/prevent-LD-training.html
    3. Hotel Guidance:
      Considerations for Hotel Owners and Managers: How to Prevent Legionnaires’ Disease
      https://www.cdc.gov/legionella/wmp/hotel-owners-managers.html
    4. Operating Public Hot Tubs for pool staff and owners
      https://www.cdc.gov/healthywater/swimming/aquatics-professionals/operating-public-hot-tubs.html
    5. From Plumbing to Patients
      Water management programs in healthcare facilities are an important way to help protect vulnerable patient populations as well as staff and visitors.
      https://www.cdc.gov/hai/prevent/environment/water.html
    6. Preventing Occupational Exposure to Legionella
      https://www.cdc.gov/niosh/docs/wp-solutions/2019-131/default.html
  2. Ensure your water heater is properly maintained and the temperature is correctly set
    1. Determine if your manufacturer recommends draining the water heater after a prolonged period of disuse. Ensure that all maintenance activities are carried out according to the manufacturer’s instructions or by professionals.
    2. Make sure that your water heater is set to at least 120°F
    3. Higher temperatures can further reduce the risk of Legionella growth, but ensure that you take measures to prevent scalding if you water heater is set to >130°F
  3. Flush your water system
    1. Flush hot and cold water through all points of use (e.g., showers, sink faucets)
      1. Flushing may need to occur in segments (e.g., floors or individual rooms) due to facility size and water pressure. The purpose of building flushing is to replace all water inside building piping with fresh water.
    2. Flush until the hot water reaches its maximum temperature
  4. Clean all decorative water features, such as fountains.
    1. Be sure to follow any recommended manufacturer guidelines for cleaning
    2. Ensure that decorative water features are free of visible slime or biofilm
    3. After the water feature has been re-filled, measure disinfectant levels to ensure that the water is safe for use
  5. Ensure hot tubs/spas are safe for use
    1. Check for existing guidelines from your local or state regulatory agency before use
    2. Ensure that hot tubs/spas are free of visible slime or biofilm before filling with water
    3. Perform a hot tub/spa disinfection procedure before use
      1. CDC Guidance (start at Step 4): https://www.cdc.gov/legionella/downloads/hot-tub-disinfection.pdfpdf icon
  6. Ensure cooling towers are clean and well-maintained
    1. Ensure that cooling towers are maintained (including start-up and shut-down procedures) per manufactures guidelines and industry best practices
    2. Ensure that the tower and basin are free of visible slime or biofilm before use
      1. If the tower appears well-maintained, perform an online disinfection procedure
  7. Ensure safety equipment including fire sprinkler systems, eye wash stations, and safety showers are clean and well-maintained
    1. Regularly flush, clean, and disinfect these systems according to manufacturers’ specifications.
  8. Maintain your water system
    1. Consider contacting your local water utility to learn about any recent disruptions in the water supply. This could include working with the local water utility to ensure that standard checkpoints near the building or at the meter to the building have recently been checked or request that disinfectant residual entering the building meets expected standards.
    2. After your water system has returned to normal, ensure that the risk of Legionella growth is minimized by regularly checking water quality parameters such as temperature, pH, and disinfectant levels.
    3. Follow your water management program, document activities, and promptly intervene when problems arise.

What Are Industrial Chillers?

Are you searching for “What Are Industrial Chillers?” If so All Kote Lining Inc. has you covered with both information about what they are and can handle any of your chiller repair needs in the Phoenix metro area. Industrial chillers are designated for use as refrigeration systems which cool process fluids. They are also used to dehumidify air in industrial or commercial facilities. Chillers will use either absorption cycles or vapor compression to cool. The water that is chilled by these machines is used for various applications including cooling industrial fabrication processes and to cool large commercial spaces.

Industrial Chiller Types

Each chiller has a rating of between 1 and 1000 tons of cooling energy. There are three main categories or types of chillers, evaporative condensed, water, and air chillers. Each of these types also has 4 different technologies for getting the job done, absorption, screw driven, reciprocating, and centrifugal chillers. Screws driven, reciprocating, and centrifugal are all mechanically driven systems, absorption chillers differ in the fact that its operations via a heat source and has no moving parts.

Industrial Chiller Components

Mechanical compressor type chillers have four basic components stages that the refrigerant must pass through. These are going through the evaporator, the compressor, condenser, and lastly the expansion valve. Evaporators operate at lower pressure and temperatures than chiller condensers.

How Industrial Chillers Work

Chillers work by passing refrigerant, typically water or air, through a series of components to change the condition of the refrigerant to expand and contract. This process results in heat transfer and cooling for the purpose of cooling industrial fabrication processes, or air for HVAC systems in large commercial buildings.

Condenser Stage

Condensers are the start and end of the cycle for chillers. As the refrigerant passes through the expansion valve it returns to the condenser as a superheated gas. It must be brought back down to the level where the gas is at the saturation temperature. This is the point where the condenser can start condensing the refrigerant back into a liquid. This is done by continuing to transfer heat from the refrigerant to the air. The system will continue until the refrigerant is completely condensed back down. In theory, this process happens at the outlet of the condenser. In application, a degree of subcooling is expected at the condenser outlet. To prevent liquid flashing subcooled liquid helps avoid pressure losses in the components and tubing.

Lowering Refrigerant Temperature

When the liquid leaves the condenser it is under high pressure and is at a high temperature. Before it can be used as a refrigerant again it must be cooled. This is accomplished by reducing the pressure the refrigerant is under. The relation between the pressure and temperature is a law of physics and you can count on the refrigerant cooling if the pressure is lowered.

To reduce the temperature pressure is reduced by first having a system of pressure restriction. This is accomplished with a thermostatic expansion valve. This is useful as the pressure varies based on the load on the system. A thermostatic expansion valve can adjust for load, pressure, and temperature variations as the system have lower and greater loads applied. This valve will act to lower the pressure, and by affecting the temperature of the refrigerant. The valve is limited to only produce a predetermined pressure change that fits with system design and load conditions.

The cycle has dropped in the thermostatic expansion valve. When there is a mixture of both liquid and vapor states of refrigerant Subcooling or superheating is not possible. For this reason any place in the system where both states of refrigerant exist, the pressure and saturation temperature will match.

A portion of the liquid refrigerant must boil to help exchange sufficient heat to lower the temperature of the system. This is another process that results in heat transfer and lower liquid temperature. When there is a large difference in temperature between the liquid and vapor states more refrigerant will need to be boiled off to achieve saturation temperature. This process improves greater refrigerant quality.

The last stage of the refrigerants journey is a mix of vapor and liquid. It passes through the evaporator tubing and warm air is blown over the evaporator. This is where the heat is transferred to the boiling refrigerant. The latent heat gain experience by the refrigerant causes to temperature increase, yet it does experience a change of state. In the best case scenario, the last molecule of liquid refrigerant boils off by the evaporator outlet. This is then passed through the to the compressor inlet. This is how the refrigerant is passed back to the start at the condenser.

What Is An Air Cooled Chiller?

Air-cooled chillers are a type of refrigeration system used in industrial and commercial facilities to dehumidify air and/or cool fluids. Learn more about air cooled chillers.
