Gas detectors for ammonia

Learn all about ammonia and find the right products for an ammonia gas warning system.

Ammonia and its properties

Ammonia (NH₃) is a colorless substance with a penetrating odor that is often used in agriculture, refrigeration and the chemical industry. Irritation of the eyes and respiratory tract can occur even at low concentrations; high exposure can result in breathing difficulties, chemical burns and, in the worst case, death. Our gas warning technology detects ammonia leaks at an early stage, effectively protecting employees and residents in working and industrial environments.

Questions about the detection of ammonia?

Sources of danger

Toxic exposure: Inhalation or contact with ammonia may irritate the respiratory tract, cause coughing and shortness of breath; in high concentrations even severe burns are possible.
Fire and explosion hazard: Although ammonia is flammable, it can form explosive mixtures with air in certain concentrations.
Eye and skin irritation: Contact with ammonia may cause severe eye and skin irritation and burns.
Cold burns: Because it is extremely cold, liquid ammonia can cause severe frostbite on contact with the skin.
Leaks: Ammonia gas can escape through leaking pipes or containers, which is particularly dangerous in enclosed spaces.
Environmental hazard: Ammonia damages the air and water, causing health and environmental problems.

high-risk scenarios

Leaks: Ammonia gas can escape through leaking pipes or containers, leading to dangerous concentrations and potential health risks.
Explosion and fire: In certain concentrations, ammonia can form explosive mixtures with air, which can lead to explosions or fires if ignited.
Risk of suffocation: In closed rooms, ammonia can replace oxygen, which can cause suffocation.
Accidents during storage: Incorrect storage of ammonia, especially in high concentrations or under high pressure, can cause dangerous situations such as leaks or even explosions.
Inadequate ventilation: Poor ventilation can cause ammonia gas to build up to dangerous levels, increasing the risk of poisoning.
Cold burns: Direct contact with liquid ammonia can cause severe frostbite.
Errors during maintenance and repairs: Inadequate maintenance or incorrect repairs to ammonia systems can cause unexpected leaks or accidents.

First aid

Ammonia (NH₃) poisoning can be life-threatening; it requires immediate first aid measures. How to administer first aid in the event of ammonia poisoning:

1. Evacuation without delay

Move to fresh air immediately! As an irritant gas, ammonia can cause severe damage to the respiratory tract and eyes. Be careful and do not put yourself in danger.

2. Make an emergency call

Dial the emergency services (112) and report suspected exposure to ammonia. Please provide full details, including the source of exposure and the severity of the incident.

3. Check breathing and level of consciousness

Check whether the person is conscious and breathing normally. If this is not the case, start resuscitation (cardiopulmonary resuscitation) immediately, provided you have been trained to do so.

4. fresh air and a good oxygen content

If the person is having difficulty breathing, move them to a well-ventilated area and make sure they are getting enough oxygen. If possible, use a face mask to provide oxygen.

5. Eye contact

In case of contact with ammonia, rinse eyes immediately with plenty of water for at least 15 minutes while keeping them wide open. Avoid rubbing the eyes.

6. The recovery position

If the person is conscious but dazed, place them in the recovery position to ensure that their airways are clear and they do not choke on their vomit.

7. Respect the person

Keep a constant eye on breathing and consciousness until the emergency services arrive. Watch for signs of respiratory distress or shock.

8. Further measures

Provide all arriving emergency responders with all important information regarding exposure, including the duration of exposure and the circumstances of the incident.

Important note:

Avoid direct contact with ammonia, especially if large quantities or high concentrations are involved. If you suspect exposure to ammonia, always wear suitable respiratory protection and protective clothing. Quick action and the right help can prevent serious damage to health.

In case of unintentional release

In the event of an accidental ammonia release, quick and coordinated action is crucial to protect people in the vicinity. Follow these steps:

1. Clearing the danger zone

Leave the area immediately, especially if you are in the vicinity of ammonia sources such as refrigeration systems or chemical processes.
Alert others nearby and help everyone to leave the area quickly and safely.

2. Optimise ventilation

Open doors and windows wide to remove the ammonia from the area and replace it with fresh air.
If available, activate ventilation systems to improve ventilation.

3. deactivate the source of ammonia emissions

If it is safe to do so, deactivate the ammonia source (e.g. chillers, valves).
Be careful and avoid putting yourself in unnecessary danger.

4. Trigger the alarm

Immediately call the emergency services (112) for professional assistance, especially if people are affected or the ammonia cannot be removed quickly.
Provide clear information about the situation and the source of the ammonia.

5. Rescue of persons (only if it is safe to do so)

Only attempt to help people out of the danger zone if it is safe to do so and you are not putting yourself in danger.
Keep in mind that high concentrations of ammonia can cause shortness of breath, irritation and even unconsciousness.

6. Administer first aid

If people show symptoms of ammonia poisoning (such as coughing, respiratory irritation or nausea), follow the first aid measures for ammonia exposure:
- Escort the person outside.
- Add oxygen if necessary.
- Observe breathing and level of consciousness.

7. Warning and securing by cordoning off the area

7. Warning and cordoning off: Cordon off the danger area to prevent others from accidentally entering it until the danger has been removed.

Important note:

You should not enter the affected area without adequate respiratory protection, especially if the ammonia concentration is high or you are not familiar with it.
An ammonia leak can cause serious accidents; it is therefore essential to always act with caution and foresight.

Ammonia is a colorless gas with a pungent odor that irritates the respiratory tract at high concentrations and can endanger oxygen uptake.

Ammonia

Special applications
