What are the components of cold chain?
The cold chain has three main components: transport and storage equipment, trained personnel, and efficient management procedures. All three elements must combine to ensure safe vaccine transport and storage (Fig. 1) (CDC, 2008).
What is the formula for calculating wastage?
Calculating the wastage factor wastage factor (wf) = 100 ÷ (100 minus the % wastage rate) where the wastage rate is the number of doses wasted, expressed as a percentage.
What are the types of cold chain?
There are two types of cold chain packaging systems: active and passive. Active systems consist of cold chain transport containers featuring advanced electric or battery-powered temperature controls. Active systems often have built-in cooling units or rely on dry ice as a coolant.
What are cold chain products?
A cold chain product is any product that is temperature sensitive. Examples of cold chain products include pharmaceuticals, vaccines, biologics, lab samples, diagnostic materials, chemicals, food, and beverages.
What are cold chains principles?
The “Cold Chain” is the system of transporting and storing vaccines within the temperature range of 35°F (2°C) to 45°F (8°C). The cold chain begins when vaccine is manufactured, moves through to the state distribution center and ends with the local immunization provider at the time of administration.
How do you calculate wastage in Excel?
Basic Excel percentage formula
- Enter the formula =C2/B2 in cell D2, and copy it down to as many rows as you need.
- Click the Percent Style button (Home tab > Number group) to display the resulting decimal fractions as percentages.
How is scrap percentage calculated?
The basic formula: % of scrap = Scrap material / Materials intake (amount of material put into the process)
What are the tools used for monitoring cold chain?
Rigorous temperature monitoring is critical for detecting any breaks in the cold chain: – International transport: temperature recorder, cold chain monitoring card; – Refrigerator: thermometer, temperature monitoring sheet and Stop!
What is wastage rate?
The definition of wastage rate in the dictionary is the drop-out rate from a company, college, or other organization, especially before they have completed their education or training.
How do you calculate vaccination coverage?
The immunization coverage rate is measured by comparing the number of doses actually given and the number in the target population of surviving infants under one year of age (these are the eligible infants). The result is expressed as a percentage.
What is cold chain packaging?
Cold chain packaging is a system of packaging and shipping goods maintaining a consistent temperature from manufacture to final destination.
What is the annual cold chain management record?
The Annual Cold Chain Management Record is a tool for immunisation providers designed to allow them to keep their daily minimum and maximum temperatures recordings and a record of their cold chain actions, equipment checks and services in one place.
What are cold chain asset trackers with data logging?
Cold chain asset trackers with data logging require a microcontroller, wireless connectivity, and sensors for close monitoring and tight control or cold chain logistics. ROHM offers all of these solutions utilizing Lapis Technology and Kionix sensors.
What is cold chain logistics and how does it work?
The term “cold chain” refers to the supply chain that delivers products or materials that will be spoiled or destroyed if temperature varies beyond a prescribed range. Many food items, chemicals, and pharmaceuticals require tightly controlled “cold chain” logistics.
