Perchloric Hood Removal

Used in laboratories and universities, perchloric acid is a powerful oxidizing agent that may react explosively in laboratory ventilation systems. Perchloric acid reacts with alcohols and certain organics to form very unstable perchlorate esters, which have the same shattering power as nitroglycerin. These crystalline esters build up in fume hoods and ducts and can explode violently when disturbed.

Perchloric Acid Decommissioning

Because of perchloric acid’s explosive nature, it is important that no one should attempt maintenance on or cleaning of hoods and exhaust systems until safe working conditions are assured.

If a laboratory hood has been exposed to heated perchloric acid, tests must be conducted to determine if explosive perchlorates have formed on the hood walls and duct system. This should be completed before inspection, cleaning, maintenance, demolition, or other work is done on any part of the hood interior or exhaust system.

At ACM Services, we have the experience, the tools, and the trained professionals to safely test and clean your exhaust system. We can also dismantle and properly dispose of contaminated hood, duct, and fan components.

Dismantling or performing maintenance on a laboratory exhaust system contaminated with shock-sensitive perchlorates is a hazardous operation. Let the professionals at ACM Services handle your project safely and economically.
