Temperature and humidity monitoring in pharmaceutical warehouses

In industry, temperature and humidity measurements are important because they can affect the cost of a product. Poor storage conditions can expose delicate drugs and biologics to changes in temperature and humidity, which can be very costly in the form of product spoilage and reduced efficacy. Therefore, temperature and humidity monitoring are important.


Hengko temperature and humidity sensors are among the most commonly used environmental sensors. It is widely used to provide the actual humidity conditions in the air at any given point or any given location. This type of equipment is often used in situations where air conditions may be extreme, or where air conditions need to be controlled for different reasons.


    1. What defines the quality of a drug

Pharmaceutical products must be manufactured, transported, stored, and dispensed in a specific manner that meets the specific product requirements specified by the manufacturer. Product quality is defined by purity, proper labeling, efficacy, and safety of use. Proper storage conditions are essential to maintain quality, and when storage conditions are poor and temperatures and humidity vary, product quality may be compromised, resulting in reduced efficacy and even the formation of volatile compounds.

Drug Storage - humidity measure

No further inspections or quality control tests are performed on individual products after the drugs are received in the warehouse. Maintaining optimal temperature and humidity conditions is critical to maintaining product quality. If a product degrades or is damaged at this point, there are no safety measures in place to prevent it from being made available to patients.


Because of this risk, it is vital that warehouses use standard procedures and trained staff to ensure that products are handled, stored, and delivered safely and with the same quality. Large warehouses will install the temperature and humidity monitoring systems, integrating the installation of many temperature and humidity measuring instruments to monitor the temperature and humidity data of the environment. Temperature and humidity monitoring systems are a valuable asset for companies with logistics quality control processes, and the installation of temperature and humidity sensors demonstrates their commitment to inventory quality and adding value to their customers, and helps build the reputation of a company with quality warehousing and high standards of service.


    2. What are GWP and GDP

Rules and regulations governing the industry have been developed to protect products from poor storage and distribution practices. some of the practices mandated by the GWP and GDP include controls on how goods are received, quality control of the warehouse storage environment, managing components and products, fulfilling picking requests, and shipping products to their destinations.


Industry-specific rules under the GWP and GDP allow manufacturers to Protect pharmaceutical products from damage during transport, Prevent product degradation due to exposure to adverse environmental/temperature conditions, avoid contamination by other materials, maintain product identification and traceability, and prevent the use of expired and damaged materials or products.


    3. Storage Best Practices

One of the most expensive problems that can occur in the pharmaceutical industry is improper storage or loss of products. Some studies have shown that 25% of vaccines may be less effective due to failure to maintain the cold chain. This means that storage conditions for pharmaceutical products are critical for pharmaceutical companies that need to protect their products and move them smoothly through the distribution chain to pharmacies.


To prevent contamination and deterioration of products during storage, the following common storage rule must be observed: No package should be left unsealed. This practice protects against possible contamination by dirt, the environment, or insects.

humidity measure for drug storage

All pharmaceutical products must be stored within their labeled temperature zones. Some examples are:

  1. Store at 2°C - 8°C,
  2. do not freeze,
  3. store below 25°C,
  4. warehouses should also use the FIFO system.

Because medications also deteriorate and lose their effectiveness over time, they have specific expiration dates. If the inventory is not rotated correctly, this practice can lead to partial downgrades or the use of older products, negatively impacting patient outcomes


Warehouses must also be aware of the chemical handling hazards of certain products in the pharmaceutical industry. Chemical spill procedures must be followed to ensure that personnel and other products are protected. To maintain the required stable environmental conditions, exterior warehouse doors and exits should be closed whenever possible. Exposure to these elements may result in temperature excursions at high or low temperatures as well as external dirt and pest contamination. Products must always be properly labeled. If it is not, or if the label is missing, the stock should not be used.


The warehouse must also be kept clean, dry, and organized at all times. Regular checks are made to ensure that storage containers and packaging are properly sealed, a regular cleaning schedule is maintained, and all spills are cleaned immediately.


Temperature and humidity monitoring is a very important part of pharmaceutical storage and all freezers and refrigerators should be monitored and alarmed. HK-J9A100 and HK-J9A200 series temperature and humidity loggers are designed to control temperature and humidity parameters within the range of -20°C to 70°C and humidity measurement range of 0% to 100%. You can use them for temperature and humidity monitoring for both indoor and outdoor product storage. The wireless sensor has a built-in lithium battery that can work for up to several years.


In addition to this, regular warehouse temperatures in other areas should be monitored, especially for goods that require storage temperatures to be maintained. All temperature records should be reviewed and analyzed frequently. All temperature deviations should be investigated and their impact assessed.
