This location conducts woodworking operations that occupy areas which equal or exceed 5000 square feet (Ft2) which is equivalent to 465 square meters (M2). (Length X Width = 5,000 ft2 OR 465 M2)

This location operates production equipment requiring a total dust collection air flow rate of 1500 cubic feet per minute (Ft3/Min) which is equal to 2549 cubic meters per hour (M3/Hr).

IF you have no dust collection equipment OR have reduced design flow, you may STILL be subject to NFPA 664 & OSHA requirements

requirements-SEE NFPA 70

HOT SURFACES - Are exterior surfaces of heated process equipment in contact with wood prevented from a MAXIMUM allowable temperature of 500 degrees (500 *F) [260 *C]?

Wood exposed to HOT SURFACES exceeding the

auto-ignition temperature of wood at 399 degrees may ignite

BEARINGS - Are they monitored for adequate lubrication and excessive wear?

Inadequate lubrication & wear leads to frictional

heating and auto-ignition of wood dust

POWERED INDUSTRIAL TRUCKS - IF they operate in areas with a deflagration hazard, are they the correct classification? (See NFPA 505)

Powered Industrial Trucks are sources of

ignition-CHECK Classification

LIGHTING - Are they designed, installed, & maintained so they aren't an ignition hazard during normal operation OR catastrophic failure?

Evaluate & Upgrade lighting to low

temperature & enclosed devices

FUEL FIRED EQUIPMENT - Are they designed, installed, & maintained so they aren't an ignition hazard? (See NFPA 31-Oil Burning, NFPA 54-Fuel Gas, NFPA 85-Boilers Combustion)?

CHECK fuel fired equipment against NFPA

31 requirements

STATIC ELECTRICITY - Does equipment contain design features that include - Conductivity, bonding & grounding, grounded metal combs, other effective means approved by the AHJ?

Consult electrician for Static Electricity minimizations

MACHINES & PROCESSING EQUIPMENT - Are they operated per manufacturer's specifications, at a condition of sharpness to minimize heat, and abrasives used within design life?

Look for equipment generation of sparks and

ignition

PARTICULATE CONVEYING & DUST COLLECTION SYSTEMS - Was a HAZARD ANALYSIS done to determine if the materials was GREEN, DRY NON-DEFLAGRABLE, or DEFLAGRABLE?

A Hazard Analysis must be conducted

FIRE & DEFLAGRATION HAZARD - Is ONLY GREEN MATERIAL collected or conveyed in A SPECIFIC area? (IF YES, Fire & Deflagration hazards are deemed non-exist in that area)

IF green & dry material present - NFPA 664 controls required

FIRE & DEFLAGRATION HAZARD - Is DRY WOOD PARTICULATE collected or conveyed in A SPECIFIC area? (IF YES, A Fire hazard is deemed to exist in that area)

NFPA 664 controls required

FIRE & DEFLAGRATION HAZARD - Is OR Could DRY WOOD PARTICULATE be suspended in air? (IF YES, A Deflagration hazard is deemed to exist in that area)

PNEUMATIC CONVEYING & DUST COLLECTION SYSTEMS - Are ANY OTHER spark producing systems tied into the woodworking particle conveying system?

System A: 1-Material Entry Point > 2-Listed Spark Detection & Extinguishing System > 3-Collection Equipment


& ground

C542

1 - The analysis needs to address each entry point in the system where downstream particles are present. Moisture content and particle size will affect the particle's "deflagrability". 2 - This is a highly technical question that requires calculating a "MINIMUM EXPLOSIBLE CONCENTRATION" (MEC) for all deflagrable material. You will need to consult NFPA 664 and an engineer for this analysis.

C551

The NFPA states that 75% of the MINIMUM EXPLOSIBLE CONCENTRATION (MEC) in air triggers the presumption. Because AIR SAMPLING under the OSHA Combustible Dust Compliance Directive is NOT SPECIFIED OR REQUIRED to assess this level, you MUST assume that dust in air can be "deflagrable".

C554

1 - NFPA 654 contains the design requirements. It's full title is "Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Dust Solids. In some cases, NFPA 664 may qualify the design requirements, but that will be identified.

1 - NFPA 654 contains the design requirements. It's full title is "Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Dust Solids. In some cases, NFPA 664 may qualify the design requirements, but that will be identified.

C560

1 - AFTER a duct system has been balanced, additional pick-up points, duct modifications, etc can REDUCE SYSTEM PERFORMANCE. 2 - You must ensure system performs as originally designed. Consult a ventilation engineer to verify system performance.

C566

1 - NFPA specifically REQUIRES ductwork to be made of metal because they are conductive. PLASTICS are non-conductive, and as a result, will accumulate static electric charges which is an ignition source. 2 - NFPA specifically lists PVC as a nonconductive, non-permitted material for duct construction. 3 - The one EXCEPTION to this is that "flexible ducting shall be permitted for final machine connection in a length not exceeding the minimum required for machine operation". (NFPA). 4 - Lengths of flexible plastic ducting that are "excessive", or a replacement for metallic ducting is a subjective judgment call. The best practice is to minimize plastic duct length. 5 - Duct repairs with plastic instead of metal is NOT ALLOWED.

C577

1 - To make the inspection of system presence easy, the ORDER of component occurrence is structured into the statement. The (Material Entry Point) precedes the LISTED spark detection & extinguishing system because it matters. The listed system MUST be DOWNSTREAM from the material entry point. 2 - A "LISTED" system means one that has been tested and approved by an organization that actually tests and issues approvals, such as Underwriter's Laboratories (UL) or Factory Mutual (FM). Note that REGULATORY AGENCIES ARE NOT APPROVAL ORGANIZATIONS! There is no such thing as an "OSHA APPROVED" system. 3 This means that self-designed, self-built, and self-installed systems that have not been tested by an approval issuing entity are NOT LISTED, and ARE NOT ACCEPTABLE!

In that case, the system is "subject to" an acceptable risk analysis by the AUTHORITY HAVING JURISDICTION (AHJ). If, in their determination, the risk of fire or deflagration is minimal, there may be no conditions requiring engineered system controls.

C592

1 - These system features must be professionally designed. Ultimately, the AHJ must accept their design, which means that there must be an engineer involved. Material thicknesses and design are complex calculations.

A1319

INSTRUCTIONS FOR DOCUMENT USERS: 1-The checklist questions are listed in a specific order. At this point in the checklist, you either have a DEFLAGRATION HAZARD and / or an EXPLOSION HAZARD. 2-If you have EITHER HAZARD, the use of NFPA Codes will help you engineer out the hazards. At this point, formulate a plan of preventive or corrective action. This checklist specified requirements or references to help you make the changes and upgrades you need to control and minimize deflagrations and explosions. After that has been done, re-assess your location using this same checklist and the follow-up scores will be calculated. You'll be able to exit out NEXT TIME after you applied the FIXES identified by this checklist.
