NFPA 660 FAQ
Does a vacuum need an NFPA 660 compliance cert for low Kst dust collection in ORDLOC?
According to NFPA 660 (page 660-35) it needs to meet the following best-practice build criteria:
8.4.2.2.1.7* For portable vacuum cleaners used with combustible dusts having a minimum ignition energy less than 30 mJ, the path to ground shall be verified prior to use after each movement or new connection, or both.
8.4.2.2.1.8* Portable vacuum cleaners that meet the following minimum requirements shall be permitted to be used to collect combustible particulate solids in unclassified locations:
(1) Materials of construction shall comply with 9.6.6.1.
(2) Hoses shall be conductive or static dissipative.
(3) All conductive and static dissipative components, including wands and attachments, shall be bonded and grounded.
(4) The fan or blower shall be on the clean side of the primary filtration media or wet separation chamber.
(5) The vacuum cleaner shall not be operated without filter media in place.
(6) Electrical motors shall not be located on the dirty side of the primary filtration media or wet separation chamber unless listed for Class II or Class III, Division 1, as appropriate, or Zone 20 or Zone 21 locations.
(7)* Where liquids or wet materials are picked up by the vacuum cleaner, paper filter elements shall not be used.
Why NFPA 660 vacuums are important
- They help prevent explosions by removing combustible dust from the air
- They help protect workers from the hazards of combustible dust
- They help ensure that equipment is properly designed to handle combustible dust
NFPA 660 vacuum requirements
- Vacuums used in hazardous locations must be listed for that environment
- Vacuums used to collect combustible materials in unclassified locations must meet certain design requirements
- They must be explosion-proof and properly grounded
Applications for NFPA 660 vacuums
- Welding fume extraction
- Wood dust collection
- Exhaust extraction
- Odor and gas extraction
- Laboratory and electronics
- Oil mist collection
What is an Explosion Proof Vacuum?
An Explosion-Proof Vacuum System is a vacuum system that is capable of preventing the ignition of a specified gas or vapor and operates at such an external temperature that a surrounding flammable atmosphere will not be ignited. A Nationally Recognized Testing Lab (NRTL) must certify that a vacuum system is explosion-proof.

Do I need a Certified Vacuum for Small Quantities of Conductive Metal Dust in ORDLOC?
Yes. Regardless of whether ORDLOC or HAZLOC, NFPA 660 Chapter 8 Combustible Metals states the following:
NFPA 660 Portable Vacuum Cleaners - Explosive Metal Dusts:
“The use of portable vacuum cleaners shall comply with 22.8.4.2.2. (B)*Due to the inherent hazards associated with portable electric vacuum cleaning systems, the equipment used for cleaning shall be identified for use in Class II, Group E atmosphere.”
We recommend Tiger-Vac® EXP1-5 (4W) RE HEPA and EXP1-20L (DT) RE HEPA (MFS) for residual cleanup of metal powders in ORDLOC and HAZLOC within NFPA stated volumes.

What is an Intrinsically Safe Vacuum Cleaner?
An Intrinsically Safe Vacuum is one that operates with no moving parts and no electrical parts. The power is supplied by compressed air that is fed into a tapered restriction, also called a “venturi”. Intrinsically safe vacuums are made from non-sparking metals like stainless steel and aluminum. Mild steel is not suitable as it can create a spark when a nut or a screw is vacuumed. It will create a spark when it hits the wall of the vacuum dirt-bin.
