The office workers in the office are relatively concentrated, with low mobility, long stay time and small range of activities. It can be seen that the preventive disinfection of the office space is particularly important. Today we will give you a popular science on how to do a good job in the preventive disinfection of the office space from the following aspects.
1. Air disinfection
1 .Open windows for natural ventilation, at least 2 times a day, more than 20-30 minutes each time.
2. If the windows cannot be opened for ventilation or the ventilation is poor, mechanical ventilation methods such as electric fans and exhaust fans can be used.
3. If necessary, use the circulating air air disinfection machine for disinfection. The disinfection should be started continuously, and the doors and windows should be closed when the circulating air air disinfection machine is in use.
Second, the surface of the object
1. The surface of the object that is often touched or touched, such as door handles, window handles, countertops, tables and chairs, handrails, faucets , Elevator buttons, etc. are disinfected 2 to 3 times a day. Surfaces that are not easy to touch can be disinfected once a day.
2. Use disinfectant wipes or rags to wipe and disinfect or spray with a constant sprayer. Use 1% hydrogen peroxide wet wipes or 250mg/L~500mg/L chlorine-containing disinfectant or 100mg/L~250mg/L chlorine dioxide disinfectant, and the disinfectant is prepared and used immediately. Disinfect for 10min~30min.
3. When there is pollution visible to the naked eye, the visible pollution should be removed first before spraying and disinfection. The surface of the object is completely wetted during disinfection. Use wet wipes or alcohol to wipe and disinfect electronic equipment or operating instruments, and remove surface residues after the disinfection time is up. Wear gloves when touching the disinfectant to avoid skin damage.
3. Ground and walls
1. In general, Wall surfaces do not require routine disinfection. The ground is disinfected 1-2 times a day if necessary. When the ground or walls are contaminated by excrement, vomit or secretions, disinfect them in time after removing the pollutants.
2. Disinfect by mopping, wiping or spraying with a constant sprayer. 250mg/L~500mg/L chlorine-containing disinfectant or 100mg/L~250mg/L chlorine dioxide disinfectant for cleaning parts. 500mg/L~1000mg/L chlorine-containing disinfectant or 200mg/L~500mg/L chlorine dioxide disinfectant for contaminated parts. Disinfect for 10min~30min.
4. Water dispenser
1. Disinfect every day 1 time. For the disinfection of the water nozzle, you can dip a cotton swab into the water nozzle to wipe and disinfect it, or use a burning water nozzle.
2. Dip 75% ethanol into the water nozzle to wipe and disinfect. Or dip a cotton swab in ethanol and ignite it, and burn it at the water nozzle with a flame for 10 seconds. After the disinfection is completed, open the water nozzle and rinse for more than 10 seconds to remove the disinfectant residue.Keep.
V. Handwashing sink and toilet
1. Disinfect after each cleaning, and disinfect twice a day. Use disinfectant wipes or rags soaked in disinfectant solution to wipe and disinfect, or use a constant sprayer to spray for disinfection.
2. Use 1% hydrogen peroxide wipes or 500mg/L~1000mg/L chlorine-containing disinfectant or 200mg/L~500mg/L chlorine dioxide disinfectant. Disinfect for 10min~30min.
6. Hand Hygiene
1..Washing hands Hand sanitizer and paper towels are provided at the pool. Provide hand sanitizers at the front desk, elevators, conference rooms, restaurants and other places. Follow the “seven-step hand washing method” to wash your hands properly.
Seventh, trash cans, etc.
Disinfect once a day. Wipe and disinfect with a rag soaked in disinfectant, or spray with a constant sprayer. 500mg/L—1000mg/L chlorine (bromine) disinfectant solution for spraying or wiping, or 1% hydrogen peroxide wipes and disinfectant solution for wiping or spraying.
The above are a few places in the office that need to be focused on preventive disinfection. When performing preventive disinfection, remember that the concentration of disinfectant should not be too high to avoid corrosion and damage to the human body. At the same time, after using the chlorine-containing disinfectant to reach the action time, the parts that are prone to corrosion should be wiped clean with clean water to avoid damage to office supplies.
