| Ching-yee, not only should we keep our hands clean |
| Familiarise ourselves with donning and doffing of PPE |
| Keep the environment clean and perform pest control, we should get prepared |
| to handle cases of emerging infectious diseases all the time |
| Understood |
| The Centre for Health Protection has reported that |
| a man with recent travel history to affected areas of a novel infectious disease |
| has been admitted for being unwell with vomiting |
| He is suspected to be infected with the novel infectious disease |
| The case has visited a local shopping centre after returning to Hong Kong |
| The Centre advises citizens to remain vigilant and adopt appropriate health precautions |
| to maintain proper personal, food and environmental hygiene |
| Mr Fong, the suspected case has visited a location near our shopping centre |
| Do we need to get prepared? |
| Ching-yee, that's a good mindset |
| First I would arrange Chun from the Security team to closely monitor the security cameras |
| for any abnormalities in the shopping centre |
| Report to the security for any suspicious activity in the centre |
| so that the area can be cordoned off |
| to prevent further spread of viruses |
| Ching and Kit, let’s run a drill on the 2nd floor of zone A |
| We can teach Ching-yee and refresh our memories at the same time |
| Sure. I'll meet Ling at the cleaning room |
| and prepare the cleaning trolley and PPE together |
| See you there |
| Don't forget that we should have donned a full set of PPE |
| before entering the cordoned off area |
| Let me meet with the security staff to cordon off the area first |
| Even though we are not performing any duty within the contaminated area, |
| we should still protect ourselves by wearing masks |
| Drill: Environmental Cleaning and Disinfection for Suspected |
| Novel / Severe Emerging Infectious Diseases |
| Let me explain the proper cleaning procedures |
| All potentially contaminated surfaces or items such as elevator control panels, door knobs |
| should be disinfected with 1 : 49 diluted household bleach |
| (mixing 1 part of 5.25% bleach with 49 parts of water) |
| Leave it for 15 to 30 minutes. Then rinse with water and wipe dry |
| In this case, a higher concentration of bleach with 1 : 4 diluted household bleach |
| (mixing 1 part of 5.25% bleach with 4 parts of water) should be used for disinfection |
| Used forceps and disposable towels must be discarded in a lidded rubbish bin |
| Disinfect the contaminated area and its neighbouring 2 metres |
| with 1 : 4 diluted household bleach (mixing 1 part of 5.25% bleach with 4 parts of water) |
| Ching-yee, vomitus should be wiped from the outer area towards the centre |
| Do not do it in the opposite direction |
| Used mop head must be discarded in a lidded rubbish bin |
| Wait for 10 minutes, then rinse with water and wipe till dry |
| Remove the PPE after completion of environmental cleaning |
