Given the characteristics of a hot and humid weather, combining with a prolong raining season in Vietnam, this is the ideal condition for pathogens and bacteria to proliferate and affect human health.

Especially at the time when the context of the Covid-19 pandemic is still very complicated and unpredictable, paying more attention to disinfection and hygiene service becomes a must.

Organizations, agencies, schools and hospitals should periodically disinfect their facilities and working places. This will:

• Reduces the risk of infection because germs and bacteria have no place to live and grow through surfaces.
• Minimizes the risk of virus spreading from infected patients through droplets that can remain airborne for a prolonged period of time.

What is Cloramin B?

Cloramin B is a specialized chemical used to disinfect surfaces with the main chemical composition being Sodium Benzensulfochleramin. In addition, Cloramin B contains active chlorine which has a strong oxidizing property.

Caution: According to Vietnam Law and Regulations, Disinfection Services using Cloramin B needed to be certified and licensed by the Department of Health.

Preparation of Cloramin B solution

Depending on the specific using purpose, Cloramin B solution will require an appropriate centration ratio. Normally, for epidemic preventive activities, the concentrations of Cloramin B commonly used are 0.5% and 1.25%.

Mixing Method for epidemic prevention activities:

m = (c% x V/C%) x 1000

m: amount of chemical required (g)
c%: concentration of solution after mixed (%)
C%: initial concentration of chlorine-containing chemicals (Cloramin B 25%, Chlorin 70%, Chlorin 90%…)
V: volume of solution after mixed (L)

Example: To make 10 liters of 0.5% Cloramin B solution from Cloramin B 25% powder, it takes (0.5 x 10 / 25) x 1000 = 200 grams.

ATTENTION:

• Although it is a recommended chemical to disinfect, Cloramin B can be toxic when mixed at high concentrations ration above 2%.
• When mixing Cloramin B, it is important to wear rubber gloves and protective masks to ensure labor safety and to avoid working accidents.
• In the event of Cloramin B poisoning, promptly provide the victim with warm water or sodium bicarbonate to neutralize the chemical.
