DID YOU KNOW?
In 1988, the UN listed hydrochloric acid (HCl) as a Table II chemical under international drug regulations — due to its use in illegal drug synthesis. [3]
KNOW THE RISK
- Concentrated acids can cause serious chemical burns, respiratory harm, and eye damage. Even small splashes can result in permanent injury. [1]
- Common acids include hydrochloric acid (used in cleaning), sulfuric acid (in batteries), and nitric acid (in manufacturing).
- Acids become especially dangerous when mixed improperly with water — creating violent exothermic (heat-releasing) reactions that can boil, spatter, or explode. [2]
MITIGATE THE RISK
1. Always Add Acid to Water — Never the Reverse
- Slowly pour acid into water to dilute it safely. Pouring water into acid can cause instant boiling and dangerous splashing. [2]
2. Understand the Heat Reaction
- Mixing strong acids with water releases heat. This heat can vaporize liquid and result in explosive reactions if handled improperly. [2]
3. Use Proper Ventilation
- Acid fumes are corrosive and can damage airways. Work in fume hoods or well-ventilated areas, and wear proper respiratory protection as needed. [2]
4. Wear the Right PPE
- Always use chemical goggles, face shield, acid-resistant gloves, and long sleeves when handling concentrated acids. [2]
CHEMICAL SAFETY REMINDER
When it comes to acid handling, there’s no room for improvisation. Follow the rule: “Always add acid to water” to avoid dangerous thermal reactions — and never forget your PPE.
