#1. A non-pharma example of measuring temperature (MOHAMMED)
The mercury-in-glass or mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam. It consists of a bulb containing mercury attached to a glass tube of narrow diameter; the volume of mercury in the tube is much less than the volume in the bulb. The volume of mercury changes slightly with temperature; the small change in volume drives the narrow mercury column a relatively long way up the tube. The space above the mercury may be filled with nitrogen or it may be at less than atmospheric pressure, a partial vacuum.
In order to calibrate the thermometer, the bulb is made to reach thermal equilibrium with a temperature standard such as an ice/water mixture, and then with another standard such as water/vapour, and the tube is divided into regular intervals between the fixed points. In principle, thermometers made of different material (e.g., coloured alcohol thermometers) might be expected to give different intermediate readings due to different expansion properties; in practice the substances used are chosen to have reasonably linear expansion characteristics as a function of true thermodynamic temperature, and so give similar results.
Clinically, sublingual area is the most usable area for temperature reading. followed by axilla and leastly the rectum. Reading from rectum 0.5 c above the body temperature.

#8. Dispatch of temperature sensitive products from a storage facility (XIN YIN)
No ice packs are required for such transport for these temperature sensitive products.

#1. A non-pharma example of measuring temperature + #4. An instance thermometer is used as a monitoring device (XIN YIN)
What else with quick accessible tools to get an estimate of the surrounding temperature? A smartphone app just for a quick reference.
#2. An example of good warehousekeeping (XIN YIN)
The cover up with plastics prevents dust build up on top of the packaging of the raw materials.
I came across this 2 weeks ago in one of my inspection. Though a simple racking but I like this as the company have took initiatives to cover the rack up with translucent plastic on those slow moving raw material.

SCAVENGER HUNT LIST - Increase your powers of observation on items related cold chain and good storage & distribution practices
Scavenger hunt is a game in which the organizers prepare a list defining specific items. Then, the participants seek to gather all the items on the list and take photographs of the items, as specified.
For fun and learning purposes throughout the course, we will be hunting a list of items as described below. You need to find these items in your own settings, searching and finding others’ photographs in the web is not acceptable.
We want each of you to find as many items as possible and post your hunt (the photograph and the story behind it) to this blog. You do not need to wait until you compile all of them, post your hunt as you find one and then the other. Increase your powers of observation on items related cold chain and good storage & distribution practices.
