PERCHLORIC ACID
PERCHLORIC ACID
- Perchloric Acid
- Use goggles for eye protection whenever the acid is handled
- In wet combustion with perchloric acid, treat the sample first with nitric acid to destroy easily oxidizable matter.
- Any procedure involving heating of the perchloric acid should be conducted in a ventilated hood equipped with water wash down.
- Perchloric acid hoods should be constructed of materials that are acid resistant, non-reactive and impervious to perchloric acid, such as stainless steel.
- Organic material should not be stored in the perchloric hood.
- Do not allow perchloric acid to come in contact with strong dehydrating agents (concentrated sulfuric acid, anhydrous phosphorous pentoxide, etc.)
- Perchloric acid should be used only in standard analytical procedures from well recognized analytical texts. Researchers should take the properties and hazards of perchloric acid into consideration before use.
- If a laboratory hood or exhaust system has been exposed to perchloric acid heated above ambient temperature, tests should be conducted for explosive perchlorates before any inspection, cleaning, maintenance, or any other work is done on any part of the exhaust system or hood interior.
