🧪 A safe shop starts with keeping chlorine away from acids and ammonia
Chlorine bleach produces toxic gas when it meets acids or ammonia, and laundries keep both in the same room, because the sour used in the final rinse is a mild acid. According to US public health agencies, bleach mixed with acid releases chlorine gas, and bleach mixed with ammonia (including urine) produces chloramine gas.
Chemical store checklist
1. Store chlorine products on a separate shelf or in a separate area from acid products such as sours and rust removers.
2. Use separate buckets, funnels and measuring containers, label them, and rinse them thoroughly before switching chemicals.
3. Do not mix different stain removers, especially ammonia and chlorine.
4. Store chemicals in a well-ventilated, locked room.
5. Post first-aid instructions in the room: move anyone who has inhaled fumes to fresh air, and if breathing gets worse, take them to hospital immediately.
Skip these steps and even brief exposure to the fumes irritates the eyes, nose and throat. Higher exposure can cause chest pain and fluid in the lungs, and very high levels can be fatal. Also read the labels and safety data sheets of the chemicals used in your shop.
