A Story From the Field: The Small Room Beside the Canteen

"Khun Fatimah" works in the human resources department of an automotive parts factory in Bang Phli district, Samut Prakan. The plant employs several hundred people across three shifts, and around sixty of them are Muslim. Some years ago the company set aside a small prayer room next to the canteen. It has a large prayer carpet, a cabinet for copies of the Quran and prayer garments, and separate wudu (ablution) areas for men and women at the back. For many employees, that quiet room is one of the most valued parts of their working day.

During the floods of early October 2026, water from the canal beside the factory flowed into the ground floor to a depth of roughly a hand span and stayed for three days. Production lines stopped. Once the water drained away, the maintenance team rushed to get the machines running again, and the canteen was scrubbed and reopened within two days. The prayer room, however, stayed locked. Nobody was quite sure how it should be handled, and nobody wanted to get it wrong.

When Khun Fatimah finally opened the door, the musty smell of a soaked carpet rolled out to meet her. The carpet had changed color in a clear line at the height the water had reached. Along the bottom of the walls there were mud stains and the first black specks of mold. In the wudu area, silt was still sitting in the drainage channel, and a sewer smell drifted up from the drains. In the meantime, Muslim employees had been praying in a corner of a meeting room or in their cars. One of them told her politely, "We would love to have the prayer room back soon, but please, only when it is truly clean."

For HR, the questions came in layers. How do you clean and disinfect a prayer room so it is genuinely clean again? How do you do it in a way that respects the space and the feelings of employees? How do you schedule the work so that it never clashes with prayer times on any shift? And how do you communicate with staff throughout? This article brings together the approach the World Health Disinfection (WHD) team uses for this kind of job.

Why a Factory Prayer Room Needs Special Care After a Flood

• It is a space that must be especially clean. Cleanliness is central to prayer: the worshipper must be clean and so must the place of prayer. A room with mud residue or the smell of wastewater cannot be used, even if it looks dry on the surface.
• Foreheads and hands touch the carpet directly. During prostration, the forehead, nose and palms rest on the carpet or prayer mat. If that surface still carries germs or mold spores, worshippers come into direct contact with it several times a day.
• Large carpets hold water deep down. Floodwater soaks through to the underlay and the floor beneath. The top of the carpet may dry within a few days, but the layers underneath stay damp and become a source of mold that keeps releasing musty odors.
• The wudu area is always wet. Water is used there many times a day. If drains still hold silt or water backs up from the public sewer, it becomes one of the main places where germs collect.
• It is shared by several shifts. Dozens of employees from three shifts use the same room throughout the day and night, so germs can spread easily via shared surfaces such as door handles, taps and shoe racks.
• It matters for morale. A prayer room is a welfare benefit with deep personal meaning. Restoring it with care shows employees that the company values them as people, not just as workers on a line.

It is worth remembering that for a factory, the prayer room is often one of the smallest rooms on site, which makes it easy to postpone while bigger repairs take priority. Yet it may be the room that most strongly shapes how a group of employees feels about the company's response to the flood.

Employee Health Risks That Should Not Be Overlooked

The following is general information, not medical advice. Employees with unusual symptoms should see a doctor or visit the factory's first-aid room.

• Allergies and breathing: Mold spores in carpets and walls can cause sneezing, a blocked nose and coughing, or trigger asthma, especially when people bow close to the floor during prayer.
• Skin: Repeated contact with a carpet or floor that is still damp can cause itchy rashes on the forehead, palms or knees.
• Stomach and digestion: A wudu area still contaminated by floodwater may harbor organisms that cause diarrhea, since water and hands come into contact with the face and mouth during ablution.
• Leptospirosis: This infection travels with floodwater and rat urine. Anyone cleaning the area should wear boots and gloves and keep cuts away from water and mud.

For the factory, the impact also includes more sick leave, lower employee satisfaction and damage to its reputation as an employer that cares about a diverse workforce. Many factories in Bang Phli supply international customers who audit welfare and inclusion practices, so how a prayer room is treated after a disaster can matter beyond the factory gate. For more information on post-flood illness, see the Thai Department of Disease Control and the WHO fact sheet on floods.

Why Common Shortcuts Don't Suit a Prayer Room

• Spraying bleach on the carpet. It leaves pale patches and damages the fibers, leaves a strong chlorine smell for a long time, and does nothing to dry or clean the underlay beneath.
• Running fans or air conditioning to dry it out. This lowers surface moisture, but if the carpet already has mold, moving air spreads spores around the room.
• Spraying air freshener. It masks the smell for a while, and strong fragrances can distract worshippers from their prayers.
• Laying a new carpet over the old one. Moisture from the old carpet and the floor underneath is trapped. Before long the new carpet smells musty and grows mold too.
• Cleaning only the taps. Most of the germs and odor in a wudu area live in the drainage channels, pipes and tile grout, not on the taps themselves.

What works is making a clear decision about the carpet, removing all mud and silt, getting the floor truly dry, and then disinfecting surfaces and dealing with mold and odor in the air in a planned sequence.

The Solution: Disinfection and Ozone Treatment Planned With Muslim Employee Representatives

WHD provides a professional disinfection service using CHEMGENE HLD4H applied with ULV fogging equipment. The mist is fine enough to reach wall joints, floor edges, the space under cabinets and drainage channels. The disinfectant does not have the sharp smell of bleach, which suits a room meant to feel calm. This is combined with our ozone treatment service, which helps destroy mold spores and break down odor molecules in the air without any need for fragrance.

Principles of Respect We Follow

• Always consult Muslim employee representatives first. HR should invite employee representatives or whoever looks after the prayer room to join the planning. If further religious guidance is wanted, an imam or knowledgeable person from a nearby community can be consulted.
• Muslim employees move the important items themselves. Copies of the Quran, religious books, prayer garments and other items of religious significance are packed and moved by the employee representatives in the proper manner. Our team does not touch these items.
• No clashes with prayer times. Work is planned to fall between the daily prayer times and to avoid Friday congregational prayer. Where possible, it is done on a factory holiday, and a clean temporary prayer space is set up in the meantime.
• Product information is shared openly. If employee representatives want to know what is in the disinfectant, our team can provide product information in advance so they can consider it.
• Respectful conduct. Team members remove shoes at the designated point once the area is clean, keep noise to a minimum and never bring food or drink into the room.

How the Work Proceeds

1. Joint survey and planning. We inspect the prayer room, wudu areas, drains and walls with HR, the facilities team and employee representatives, and fix a date and time that avoid prayer times.
2. Advice on carpets and clean-up. Large carpets soaked in floodwater for several days usually need replacing. Small rugs and washable prayer mats should be washed and dried completely. We advise on flushing mud from wall edges and drainage channels.
3. Moving important items. Muslim employee representatives pack and move the Quran and other important items; the facilities team removes any carpet that is being replaced.
4. Chemgene HLD4H fogging. We fog floors, walls, cabinets, shoe racks, doors, the wudu area, taps and drainage channels.
5. Controlled ozone treatment. We close the room, post warning signs and run the generator for a period suited to the room size, targeting mold and odors embedded in walls and air.
6. Ventilation. Doors, windows and exhaust fans are opened, and we wait until the ozone has broken down into oxygen before anyone goes back in.
7. New carpet and re-check. Once the floor is completely dry, the new carpet is laid, employee representatives return the Quran and other items, and our team re-checks odor and former mold spots.

Before and After Restoring the Prayer Room

A Customer's Voice (Illustrative Scenario)

"What impressed me was that the team's first question was what times our employees pray. They asked our employee representatives to pack the Quran and prayer garments themselves, and they did the work on a Sunday when the factory was closed. On Monday the prayer room reopened, and quite a few employees came by to thank HR."

Checklist for HR and Facilities Teams

A prayer room project touches several departments at once. This short checklist helps keep everyone aligned and makes sure nothing is forgotten between the survey and the day the room reopens.

• Tell employees in advance when the prayer room will be closed, and set up a temporary prayer space that is clean, quiet and private.
• Coordinate with Muslim employee representatives on packing the Quran and other important items.
• Decide on carpet replacement and order the new carpet so it arrives after the floor is completely dry.
• Have a technician check the wudu drains and backflow valves.
• After reopening, set a routine for wiping taps, door handles and shoe racks with Chemgene disinfectant spray.
• Run the exhaust fan after the wudu area is used, to reduce moisture build-up.
• Keep a short record of what was done and when, so you can show employees, auditors or management that the room was restored properly.

Good communication is as important as good cleaning. A short notice on the canteen board, a message in the employee chat group and a word from line supervisors help everyone understand why the room is closed, when it will reopen, and where to pray in the meantime.

Setting Up a Temporary Prayer Space While the Room Is Closed

One of the most common mistakes after a flood is closing the prayer room without offering anything in its place. Employees then fall back on a corner of a meeting room, a storage area or the back seat of a car, which is uncomfortable, often not clean, and quietly sends the message that their needs come last. A temporary space does not have to be elaborate, but it should be planned with the same care as the main room.

• Choose a room that was not flooded. An upper-floor training room or a quiet office that stayed dry is ideal. Avoid rooms next to noisy production lines, the loading bay or areas still being cleaned with strong-smelling chemicals.
• Ask employee representatives to check the direction. They can confirm the direction of prayer for the temporary room and mark it simply, in the way they consider appropriate.
• Provide clean mats and a place for shoes. New or freshly washed prayer mats, a simple shoe rack outside the door and a small cabinet or shelf for prayer garments are usually enough.
• Arrange access to clean water for wudu. If the original wudu area is still out of use, agree with representatives on which washroom can be used temporarily, and make sure it is cleaned and disinfected more often than usual.
• Keep the room for prayer during prayer times. If the room is used for meetings at other times, make sure it is empty, tidy and quiet at the agreed prayer times for every shift, including the night shift.

Putting this temporary space in place on the same day the prayer room closes takes pressure off the restoration schedule. HR and the facilities team can then let the floor dry properly, wait for the new carpet and complete disinfection and ozone treatment in the right order, instead of rushing to reopen a room that is not yet truly ready.

Keeping the Prayer Room Dry and Fresh After It Reopens

Bang Phli is low-lying, and the rainy season does not end the day the floodwater drains away. Humidity stays high for weeks, and a prayer room with a large carpet and a wudu area next door is exactly the kind of space where moisture and odors build up again. A few simple habits make a big difference to how long the result lasts.

1. Control moisture from the wudu area. Run the exhaust fan for a while after each busy prayer time, keep the door between the wudu area and the prayer room closed, and place absorbent mats at the entrance so wet feet do not carry water onto the carpet.
2. Vacuum the carpet regularly. A vacuum with a good filter removes dust, hair and mite allergens that feed mold. For larger carpets, a periodic professional dust mite removal service helps keep the fibers clean deep down.
3. Wipe shared touch points every day. Taps, door handles, light switches and shoe racks are touched by every shift. A quick wipe with a suitable disinfectant spray is enough.
4. Watch the base of the walls. If you notice new dark spots or a musty smell returning, deal with it early before it spreads behind the carpet edge.
5. Check drains after heavy rain. If water backs up from the public sewer or the drain smells again, call maintenance quickly and keep the backflow valve in good condition.
6. Plan a follow-up treatment if needed. Where the building was badly flooded, a follow-up ozone treatment some weeks later, again scheduled between prayer times, can help keep odor and mold under control through the rest of the wet season.

Assigning one named person, perhaps a facilities staff member working with an employee representative, to look after these habits keeps the room in good condition without adding a burden to anyone else.

Frequently Asked Questions

Q: Should a flooded prayer carpet be washed or replaced?
A: A large carpet soaked in floodwater for several days usually should be replaced, because the underlay dries slowly and becomes a mold source. Small rugs and washable prayer mats should be washed and dried completely.

Q: How long will the prayer room be closed?
A: It depends on how damp the floor is and on carpet replacement. Disinfection and ozone treatment usually take one day including ventilation time.

Q: Will your team touch the Quran or religious items?
A: No. We ask Muslim employee representatives to pack and move them themselves.

Q: Can the work be done on a working day?
A: Yes, if it fits between prayer times and adjoining rooms can be closed off, but we recommend a factory holiday for convenience.

Q: Do you also handle office prayer rooms?
A: Yes. The same principles apply to prayer rooms in office buildings and warehouses: consultation first, representatives handle religious items, and scheduling around prayer times.

Q: Will the disinfectant or ozone leave a smell on the new carpet?
A: The new carpet is laid only after fogging, ozone treatment and full ventilation are finished, so it is not exposed to the treatment. The room should simply smell clean and neutral when employees return.

Q: Is the ozone treatment safe for the room afterwards?
A: Yes, provided the room is properly ventilated. Ozone breaks down into oxygen, and our team only hands the room back once ventilation is complete and the air is fresh.

Q: Which areas do you serve?
A: All of Bang Phli district, including Bang Phli Yai, Bang Kaeo, Bang Pla and Racha Thewa, as well as nearby areas such as Bang Bo, Bang Sao Thong and Mueang Samut Prakan.
