APV for Arias fume hoods

Document Responsible: Bjarke Rolighed Jeppesen

 

Date: 15 June 2021 

1) Purpose/Formål

 

The purpose of this APV instruction is to ensure that users, in the iNANO cleanroom, are aware of the potential dangers that exist when working with fume hoods from Arias. Users should be aware of the potential hazards listed below. The aim of this APV instruction is also to prevent personal injury to maintenance personnel.

 

2) The Instrument/Instrumentet

The fume hood at the left is dedicated to solvents and the working surface is made stainless steel which are chemically resistant to all solvents. The fume hood to the right is specially designed for acids and bases with the working surface made from polypropylene, chemically resistant to most acids and bases.  

 

3) Hazardous Conditions/Risiko

Safety mechanisms include sensors in the fume hood that detects larger spills, and sensors for monitoring exhaust flow. 

 

Some chemicals are not allowed in the fume hoods, therefore, always contact the superuser before new chemicals are used in the fume hoods.

 

4) Protective Clothing/Beskyttelsesdragt

 

A cleanroom suit, gloves and safety goggles must be worn.

 

5) Identification/Identifikation

Chemicals in solvents section:

Acetone, IPA, Ethanol, Methanol. Sds are available in Kiros.

Chemicals in the acid/bases section:

 

Acetic acid, Hydrochloric acid,  Sulfuric acid, Formic acid, Chromium etchant. Sds are available in Kiros.

 

6) Maintenance/Vedligeholdelse

Control of the exhaust flow every three month.

Empty integrated spill containers.

 

Control of sensors.

 

7) Additional Safety Notes/Ekstra sikkerhed

 

Keep the glass safety window in a low position to protect against chemical splashes and to keep a high exhaust flow.

 

8) Electrical Safety/Elsikkerhed

 

Potentially lethal voltages are present on the equipment. To prevent personal injury, ensure the system, circuit or component is isolated from its source of supply prior to undertaking any maintenance or repair of the equipment. Do not rely on control system interlocks or display messages as an indication that it is safe to work on potentially hazardous items.

It is recommended to work in pairs when undertaking work on live systems.
