Q

What kinds of information should an inspector be prepared to verify when onsite at a storage facility or retail outlet? (322-323, 325-326)

A
  • Changes in contents that may increase the fuel load
  • Changes in storage arrangement or height that may require changes in storage systems, in-rack sprinkler arrangements, and access aisle width.
  • Recognize appropriate distances between materials
  • Note housekeeping issues
  • Be aware of fire protection measures specified for materials

Inspectors should review storage documentation before conducting an inspection at a storage facility or retail outlet. Onsite they should verify:
- Building construction characteristics
- Location of fire walls, fire door assemblies, and fire barriers
- Types and classifications of stored commodities, including plastics
- Type of packing material used
- Methods of storage
- Maximum storage height of commodities
- Type and design of automatic sprinkler system and the fire pump if provided
- Type of water system on site; should meet minimum flow and pressure for the system
- Location of water sources, hydrants, standpipes, and fire department connections
- Locations and types of smoke and fire detectors
- Method of smoke removal
- Training records for facility personnel
- Disposal method/storage of waste and packing materials
- Introduction of high-risk commodities
- Maintain required clearances between sprinklers and stored materials
- Maintain clear specified aisle dimensions
- Fire detection and reporting systems
- Security systems
- Structural and electrical systems
- Storage methods and practices
- Locator and lot identification systems
- Documents to include household goods descriptive inventories, weight tickets, warehouse receipts, service orders

Q

What are the some of the issues with Pallet Storage? (323-324)

A

With multiple stacked pallets it is more difficult for water from a sprinkler to reach, wet, and control a fire.
- Materials are stacked 3 to 4 feet high on each pallet, with several pallets stacked this may approach 30 feet in height
- Air space between top and bottom layers of pallets (~4”) created significant fire hazard b/c provides path for promoting spread of fire
- Materials are often completely encapsulated in plastic wrap (cocooning)
- Plastic encapsulation prevents fire suppression system water from penetrating surface of stored material
- Packing/wrapping adds to the fuel load
- Pallets stacked several layers high prevent sprinkler water from reaching bottom layers
- Plastic pallets change the commodity class if sprinkler system not designed for Group A plastics

Q

What are some of the conditions an inspector should be aware of in a distillery? (373)

A

Primary hazards are fire and explosion.

Fires can occur when vapors from flammable organic compounds are released from leaks in tanks, casks, and equipment.

Dust from processing grain and combustion from wood floors, casks, and racks can cause fires or explosions.

A vapor explosion can occur if enough vapors are released in an enclosed space with an ignition source present:
- Open flames
- Torch cutting and welding
- Sparks (static, electrical, mechanical)
- Hot surfaces
- Heat from friction
- Radiant heat
- Combustible dust

All flammable materials necessary for an explosion (vapor, dust, gas) are present.

Q

What should the inspector check for at a Distillery? (373-374)

A

The best way to prevent a distillery fire is to control flammable vapors and ignition sources.
- Note venting processes so that flammable vapors inside the building do not accumulate
- Make sure electrical system in rooms where distilling or blending flammable liquids is done conforms to the NEC Class I Division 1 Hazardous Location for Group D Flammable Liquids
- Check for proper ground and bonding technique when pouring ethanol from storage container to the still container and when decanting large amounts of finished product or byproduct
- Note that heaters and natural gas appliances that use pilot lights are at least 10 feet away from the pouring and distilling areas
- Verify that fire sprinkler systems meet the fire jurisdiction’s requirements for extinguishing an ethanol distillery fire.
