Decontamination involves the process of cleansing a contaminated object or removing unclean substances particularly harmful, such as micro-organisms, hazardous materials, transmissible diseases. The treatment of infected surfaces or objects should be adequately infections free before it is being stored or discarded or washed.

The aim of decontaminating objects is to stop the spread of micro-organism and hazardous substances that poses a threat to human health and the ecosystem. Decontamination is a safety rule that has been practised in all aspects of life, both indoors and public spaces.

Moreover, the processes of Fumigation are in the method of pest control that uses chemical substances (in the form of poison, gases, or granulated materials) called pesticides. This process is applicable on household premises, public spaces, farms or gardens, and other pest-infested Environment. The exercises to Fumigation aim to curtail the spread of rodents or insects carrying diseases. This Fumigating exercise has to be operated by a professional technician who understands the full course of controlling pest, using safety tips.



the procedure to Decontaminating infection or germs varies in terms with its application, which is mostly practised by medical operatives.

  • Sterilisation: The process of removing micro-organism on a surface, especially on equipment, e.g., surgical instruments, to prevent the spread of infection; (this is also applicable to clipper used in saloons). Sterilisation is practised by the use of heat, chemical substances or gas.
  • Disinfection: the process of eradicating harmful virus or bacteria to prevent the growth of diseases carrying the micro-organism, virus and bacteria. The effectiveness of a disinfectant is applied to the rate of its infestations, the number of organisms, or proper hygiene like cleaning frequently touched surfaces.
  • Sanitation: The process of maintaining adequate hygiene dealing with specks of dirt, in avoidance to encouraging viruses and bacteria.



  • Water Distillation: this process is separating harmful substances from the water (especially drinking water) which has to be safe in terms with the reason for use. This method of purifying water included; filtration, and sedimentation. Purified water cannot be detected but for safety measures always boil water for safety use (especially for household use).
  • Heat Sterilisation: the process of heat sterilisation can either be by Steam or Dry heat. The adequate temperature of 250°F is appropriate, and it should last for 30 minutes to 1 hour. In comparison, dry sterilisation requires more time and a higher temperature for better results.
  • Disinfection: this process uses chemical substances to kill micro-organism, droplets, and viruses on surfaces. This process is less effective compared to sterilisation that does exterminate all harmful life forms, either by antibiotics which can be used on internal use or by antiseptic for external use only.
  • Antisepsis: this process involves the removal of germs from surfaces or contaminated water—the state of being free of pathogenic bacteria, micro-organisms or protection against infected by such organisms.


A certified disinfectant substance entirely wipes out 100% bacteria free without being a threat to human health. Moreover, most disinfectants are organic and should not be mixed with chemical substances. In terms of Alcohol, tends to be the most effective substance when mixed with clean water; basically, Alcohol contains ethanol. In the process of having 75% of Alcohol is highly effective in kill micro-organisms, on fresh wounds or disinfecting surfaces.
