Clorox (Bleach) Inhalation Hazards: Safety Guidelines for Enclosed Spaces

Health Risks of Bleach Fumes

Clorox products contain sodium hypochlorite (NaClO), a strong oxidizer. In poorly ventilated areas, inhalation can cause:

• Eye, nose, throat irritation
• Coughing, bronchospasm, dyspnea
• Chemical pneumonitis / pulmonary edema (high concentrations)
• Exacerbation of asthma, COPD

Concentration varies: Regular Clorox = 6% NaClO; Concentrated/Clorox Plus = 8.25%.

Safe Use Practices

• Use only in well‑ventilated areas (open windows, exhaust fans)
• Wear gloves, eye protection
• Never mix with ammonia, acids, or other cleaners – produces toxic gases (chloramine, chlorine)
• Rinse surfaces thoroughly after contact time
• Store away from children and pets
• If symptoms develop: exit area, seek fresh air, call Poison Control (1‑800‑222‑1222) or 911 if severe
