Abstract: The World Health Organisation stresses the importance of maintaining the cold chain for temperature sensitive vaccines. Due to the recommendation for rabies vaccines to be stored between 2° and 8° Celsius and the nature of canine mass vaccination projects, cold chain maintenance remains one of the most significant logistical hurdles project managers have to overcome.
Mission Rabies field teams in Malawi evaluated the use of adhesive temperature monitors as an alternative to thermometers in both storage fridges and field cooler boxes during the duration of a 4 week mass vaccination drive in April/May 2016.
Two different Timestrip® temperature monitors were used to alert the teams to the critical temperature thresholds of 0°C and 30°C. As freezing rapidly damages vaccines, each vaccine box containing 10 vials of 10ml vaccine was marked with a monitor that indicates the immediate crossing of the lower threshold through colour change. As damage from high temperatures is related to both the temperature achieved and the time of exposure, to test for the upper temperature limit each cooler box was equipped with a monitor that showed the crossing of the upper threshold over time.
Of a total of 22 vaccination teams participating in the study, 7 teams reported an exposure of the vaccines to temperatures above 30°C for more than 4 hours and on 9 occasions teams reported a temperature drop to 0°C or below.
These findings highlight the importance of monitoring the temperature during field campaigns, both due to proximity to ice packs and exposure to high outside temperatures. The use of Timestrip temperature indicators gives early visual clues and raises awareness among the team. However practicability of the temperature monitoring must be taken into consideration and adhesive monitors need to be improved with regards to their setup to make them a valuable tool in field projects.

Simple activation, clear elapsed time indicationTimestrip® 24 month time indicators are single use and show the total amount of elapsed time since activation — up to 2 years. Our elapsed time indicators are inert until activation. First, press the blister on the back of the indicator to activate. A red activation line appear in the front window. Next, the window will then fill with colour as time passes. During the monitoring period, you will be able to see the colour progress pass each time marker. The colour progression lets you know how long it has been since activation. Timestrip® 24 month has time markers at 3, 6, 9, 12, 18 and 24 months, the indicators have plenty of options for flexible time monitoring uses.

Frame Zoom Focus SnapUsing the App simply involves taking a photo of a Timestrip® label with a smartphone. If the Timestrip® has a new style serial number, the App will recognise the serial number and allow you to register it on the system. You can then take a follow on scan where you can enter its activation state (inert, activated or breached), storing this data with essential time and location information in the cloud. If the Timestrip® has an old style serial number you can still use the app in the same way but you'll need to manually enter the serial number. The App is free to download from the Google Play store with an iOS version to follow shortly. High tech low cost The App is the latest innovation from Timestrip, which revolutionised the field of cold chain management with its unique Irreversible Time and Temperature Indicator labels (TTIs). Recognised by the World Health Organisation and the US FDA as an essential tool for the cold chain management of blood and food products, TTIs provide data as to whether a blood or food product is safe to use. Timestrip’s irreversible TTIs make this crucial safety information unambiguous and instantly visible. Like having a hundred permanent digital data loggers The main benefit of Timestrip’s irreversible TTI labels is that they give essential cold chain management information on individual units of processed products. This deals with the main shortcoming of digital data loggers, which are mostly used for containers of transported and stored products. Thanks to the new Timestrip® App, extra key information around cold chain management is added with the safe storage of status, time, journey and location data, which can be accessed at any time via the app or via a website. A digital data logger can be lost or damaged and all its data can be wiped clean. The Timestrip® App however safely stores this data in the Cloud. Data logger functionality at a fraction of the price Timestrip UK CEO Reuben Isbitsky says: "I am very excited about our first App, which brings Timestrip TTI labels very close to data logger functionality, at a fraction of the price. While a key benefit of Timestrip products is that they do not need external infrastructure to read and interpret, using the optional Timestrip Temperature App to scan them, adds enhanced functionality, easy audit trail and provides the customer with a permanent record of the history of the product’s journey."
The Timestrip team regularly gets feedback from clients across the world about the value that its range of Irreversible Time and Temperature Indicators brings to making production processes safer and more secure.So in a world which normally deals with the critical issues of health and food safety, the mood in the office has been lightened with news from south-east Asia of a novel use of its 7 Days Time Indicator.
On a building site in Japan, new recruits on a construction site undergo a seven-day training programme and have a Timestrip 7 Days Time Indicator on their security helmets. Thus, when the window on the tag is completely filled with colour, site managers know that the beginners have completed their induction programme.
This strategy is particularly useful when starters begin their seven-day training programme on different days, because access to specific parts of the construction site or the handling of a particular piece of machinery can only occur once the required training linked to a related day has taken place.Until now the benefits of Timestrips have been closely aligned with the needs of food safety and securing various cold management processes for blood products as well as the Pharmaceutical, Healthcare & Life Sciences industries. This ingenious use of Timestrip 7 Days Time Indicator points to a new benefit: Health & Safety related to required training. Is your company using their Timestrips in an unusual way? If so, please contact us. We would love to hear from you.
