Malaysia's thunderstorm season can bring heavy rain, lightning, strong winds, and temporary power disruptions. Thunderstorms can occur throughout the year, with increased activity during certain inter-monsoon periods. Lightning and electrical surges can also pose risks to household electrical equipment.
For households using an oxygen concentrator, a power outage is something worth planning for before a storm arrives.
The most important step is not simply having a backup battery. You should have a clear plan that answers:
- What should you prepare before a storm?
- What should you do immediately when the power goes out?
- How long can your backup equipment operate?
- What should you do if the outage lasts longer than expected?
- When should you ask for additional assistance?
- How should you check the concentrator after power returns?
This guide provides a practical before, during, and after power-outage plan for oxygen concentrator users in Malaysia.
Why Power Outages Matter When Using an Oxygen Concentrator
Most home oxygen concentrators require household electricity. If the electricity supply is interrupted, a mains-powered concentrator may stop operating.
For someone who regularly uses oxygen equipment, waiting until the power goes out to decide what to do can create unnecessary stress.
A better approach is to prepare a simple emergency plan in advance.
Your plan should identify:
- The oxygen equipment being used
- Its normal power source
- Whether it has a compatible battery
- How long the available backup can operate
- What alternative oxygen arrangement is available
- Who should be contacted if the outage continues
- Where the user can safely go if power cannot be restored
The backup plan should be based on the user's normal oxygen requirements, equipment instructions, and established care arrangements.
1. Check the Weather Before the Storm
If thunderstorms are forecast, start preparing before the weather becomes severe.
Malaysia's Meteorological Department (METMalaysia) provides official weather information and thunderstorm warnings. Check the latest local warning before severe weather arrives.
METMalaysia official weather information and warnings
Before a storm, check:
- Thunderstorm warnings
- Heavy-rain conditions
- Strong-wind information
- Local flooding conditions
- Possible disruptions in your area
The key rule
Do not wait for the electricity to fail before preparing the oxygen equipment.
If severe weather is approaching, use the available time to check the equipment, charge compatible batteries, and review your backup plan.
2. Prepare Your Oxygen Equipment Before the Power Goes Out
A few minutes of preparation can make a major difference during an unexpected outage.
Step 1: Check the concentrator
Make sure the concentrator is operating normally.
Check for:
- Warning lights or alarms
- Damaged cables
- Loose connections
- Unusual sounds
- Unusual heat
- Damaged accessories
If something appears abnormal, follow the manufacturer's instructions rather than attempting an improvised repair.
Step 2: Charge compatible batteries
If your oxygen equipment uses a rechargeable battery:
- Charge it before the storm.
- Use the correct charger.
- Confirm the battery is properly connected.
- Keep an additional compatible battery available if your model supports one.
- Do not assume the battery's maximum listed runtime will always be achieved.
Battery runtime can vary depending on the model, oxygen delivery setting, battery condition, and operating environment.
Step 3: Prepare your backup oxygen arrangement
If the user has an established backup oxygen arrangement, make sure it is accessible and ready to use.
Do not wait until the concentrator stops working to locate the backup equipment.
Step 4: Keep important information accessible
Keep the following together:
- Oxygen concentrator model
- User manual
- Battery information
- Manufacturer/service contact information
- Equipment instructions
- Backup oxygen information
- Important family contact numbers
A family member should know where this information is stored.
3. Keep the Oxygen Concentrator Dry and Safe
Heavy rain can cause leaks, flooding, water splashes, and damp indoor conditions.
Place the concentrator:
- On a stable, dry surface
- Away from windows
- Away from leaking roofs
- Away from doors where rainwater may enter
- Away from bathrooms or damp areas
- Above areas that could become flooded
- Away from curtains and other materials that could block airflow
Do not operate electrical equipment that has been exposed to water unless it has been confirmed safe according to the manufacturer's instructions.
If flooding is occurring around your home, move to a safe location rather than attempting to protect the equipment at the expense of personal safety.
4. Check the Electrical Connection Before the Storm
Lightning and electrical surges can damage electrical equipment.
Before a storm, inspect:
- Power cables
- Plugs
- Adapters
- Electrical outlets
- Approved power accessories
- Battery chargers
Look for:
- Frayed cables
- Cracked plugs
- Loose connections
- Burn marks
- Unusual smells
Never use damaged electrical equipment.
What about unplugging the concentrator during lightning?
General electrical-safety guidance may recommend disconnecting unused electrical equipment during thunderstorms. However, if an oxygen concentrator is actively required, do not simply disconnect it without considering the user's oxygen needs and the equipment's operating instructions.
Instead, prepare the appropriate backup arrangement before severe weather arrives.
5. Create a Simple Oxygen Concentrator Power-Outage Plan
This is the most important part of storm preparation.
A useful plan should have three stages:
BEFORE → DURING → AFTER
Each family member who may need to assist should understand these steps.
Before the Power Goes Out
1. Check the current oxygen setup
Confirm:
- Which concentrator the user normally uses
- What oxygen delivery mode is being used
- What setting is normally used
- Which power source is required
Do not change the user's normal oxygen setting simply because a storm is coming.
2. Charge the battery
If the concentrator has a compatible rechargeable battery, charge it according to the manufacturer's instructions.
Record or remember when it was fully charged.
3. Check the backup arrangement
Know exactly what equipment will be used if the main concentrator cannot operate.
Do not rely on an untested or improvised backup system.
4. Keep the equipment together
Place the following where they can be found quickly:
- Concentrator
- Power adapter
- Battery
- Backup equipment
- Cannula/tubing and required accessories
- User manual
- Important contact information
5. Tell another family member
At least one other person should know:
- Where the equipment is
- How the normal setup works
- Where the backup equipment is located
- Who to contact if there is a problem
When the Power Goes Out
When electricity fails, avoid panic and follow the plan step by step.
Step 1: Confirm the power outage
Check whether:
- The entire home has lost electricity
- Only one electrical outlet has stopped working
- The concentrator has an alarm or warning
If other household equipment is also off, the problem may be a general power outage.
Step 2: Check the concentrator
Look for:
- Power failure alarms
- Battery indicators
- Warning messages
- Unusual sounds
- Signs of electrical damage
Do not repeatedly switch the equipment on and off if there is a suspected electrical problem.
Step 3: Use the established backup arrangement
If the main concentrator cannot operate, use the backup oxygen arrangement that has already been prepared for the user.
Follow the equipment instructions carefully.
Do not improvise a connection between the concentrator and an unsuitable battery, inverter, generator, or other power source.
Step 4: Check remaining battery or backup time
If using a battery-powered concentrator, check the battery indicator.
Record approximately how much operating time remains.
For example:
Battery available → Estimate remaining runtime → Monitor regularly → Prepare next step before the battery is depleted
Do not wait until the battery reaches zero before deciding what to do next.
If the Power Outage Continues
A longer outage requires additional planning.
Monitor the situation
Keep track of:
- Remaining battery capacity
- Backup oxygen availability
- Expected power restoration
- Weather conditions
- Flooding or road conditions
- Whether the user can safely remain at home
Contact the appropriate support
If the outage is continuing and your available backup may not last long enough, contact the appropriate electricity, equipment, healthcare, or emergency support before your available oxygen backup is exhausted.
Do not wait until the final minutes of battery or backup oxygen availability.
Consider moving to a safer location
If the home cannot safely support the user's oxygen equipment for the expected duration of the outage, consider relocating to a location where appropriate power and oxygen arrangements are available.
Plan transportation carefully during thunderstorms or flooding.
Never put yourself at risk by travelling through floodwater simply to obtain equipment or electricity.
What If the Battery Is Almost Empty?
This is one of the situations that should be planned for before an outage.
If the battery is running low:
Do not:
- Wait until the battery reaches zero
- Change oxygen settings without following the established plan
- Build an improvised electrical connection
- Use an unknown charger
- Connect the equipment to an unsuitable power source
- Ignore equipment alarms
Instead:
- Check the remaining battery level.
- Confirm what backup oxygen arrangement is available.
- Follow the equipment instructions.
- Contact the appropriate support if additional assistance is required.
- Arrange access to a suitable powered location or backup equipment before the available supply is exhausted.
If the user's oxygen needs cannot be met by the available backup arrangement, seek appropriate medical assistance promptly.
What If the Concentrator Gets Wet?
If rainwater, floodwater, or another liquid reaches the concentrator:
Do not assume it is safe to turn on.
Instead:
- Move away from the wet electrical equipment if there is an electrical hazard.
- Disconnect power only when it is safe to do so.
- Do not attempt to dry and immediately restart a potentially damaged electrical device.
- Follow the manufacturer's instructions.
- Contact an appropriate service provider if the equipment may have been damaged.
- Use the user's established backup oxygen arrangement while the equipment's safety is being assessed.
Personal safety should always come before protecting the equipment.
6. Keep the Concentrator's Ventilation Area Clear
Whether the concentrator is being used during normal weather or a storm, adequate airflow around the equipment is important.
Do not place the concentrator:
- Inside a closed cabinet
- Under blankets
- Under heavy fabric
- Against curtains
- Directly beside a heat source
- Where ventilation openings are blocked
Keep the surrounding area:
- Clean
- Dry
- Open
- Uncluttered
After moving the concentrator because of a storm, check that its ventilation openings have not become blocked.
7. Portable Oxygen Concentrators and Power-Outage Flexibility
Portable oxygen concentrators with battery options can provide additional flexibility when household electricity is unavailable.
However, portable does not automatically mean emergency-ready.
Before choosing or relying on a portable model, check:
- Oxygen delivery type
- Flow or pulse settings
- Battery capacity
- Expected battery duration
- Whether the battery is replaceable
- AC charging
- DC/car charging
- Weight
- Operating instructions
VARON Malaysia offers portable models with different oxygen delivery methods and battery options.
