Corrosive Substance Safety


Hazards of Corrosive Chemicals:

  • Reversible and irreversible destruction of tissue
  • Corrosion of metal
  • Release of Hydrogen in reaction with metals
  • Reactivity
  • Oxidation
  • Dehydration
  • Toxicity
  • Instability


Common Corrosives


Strong acids and bases, dehydrating agents, halogens, and oxidizing agents


Safety Tips:

  • Store below eye level
  • Store in small containers
  • Store the minimum quantity necessary for work in their compatibility groups
  • Store in secondary containment or cabinets designed to control corrosives effects on shelving

 






Acute Health Effects


Inhalation

Irritation of mucous membranes, difficulty breathing, coughing, pulmonary edema, sore throat


Ingestion


Irritation and burning sensation of lips, mouth, and throat; pain in swallowing, painful abdominal cramps; vomiting


Skin Contact


Burning, redness and swelling, painful blisters, profound damage to tissues (alkalis:  a slippery soapy feeling)

Personal Protective Equipment


Goggles


Use chemical splash goggles to protect eyes.  If splash potential, a face shield may be required over splash goggles.


Eye Wash


Flush contaminated skin or eyes for a full 15 minutes with clean, tepid water.  Do not rub eyes.  Get immediate medical attention even if you believe you have flushed all contaminant out of your eyes.


Fume Hood


Use when possible


Gloves


Check with glove compatibility charts in the Lab Resource Guide for exact chemical in use.  Neoprene and Nitrile are effective for most acids and bases.  PVC is effective for many acids.


Rubber Coated Apron
