4.10.3. Storage Tanks and Containers

4.10.3.1. Design, Fabrication and Testing

1) Storage tanks, wooden vats, barrels, drums or containers used for the storage or processing of distilled beverage alcohols shall be designed, fabricated and tested for the anticipated maximum working pressure, operating temperature, internal corrosion conditions and structural stresses to which they could be subjected.

4.10.3.2. Supports, Foundations and Anchorage

1) Supports, foundations and anchorage of storage tanks shall comply with Subsection 4.3.3., except that timber supports shall be permitted.

4.10.5. Piping and Pumping Systems

4.10.5.1. Design and Installation

1) The design, fabrication, assembly and inspection of piping and pumping systems containing distilled beverage alcohols shall be suitable for the anticipated maximum working pressures, operating temperatures, internal corrosion conditions and structural stresses to which they could be subjected. (See Appendix A.)

4.10.6. Ventilation

4.10.6.1. Ventilation

1) Natural or mechanical ventilation shall be provided for all areas where alcohol vapours are released from storage tanks or process equipment under normal operating conditions, to prevent the concentration of vapours from exceeding 25% of the lower explosive limit, measured 1.5 m from any equipment or from any opening subject to vapour release.

4.10.7. Spill Control

4.10.7.1. Spill Control

1) Emergency drainage systems shall be provided to direct any spilled or leaked distilled beverage alcohol to a safe location.

4.10.8. Fire Protection

4.10.8.1. Portable Extinguishers

1) Except as permitted in Sentence (2), in maturing warehouses, at least one portable extinguisher having a rating of 4-A:30-B:C shall be located adjacent to each exit.

2) Hose stations are permitted to be installed in lieu of portable extinguishers at locations required in Sentence (1), and spaced so that the travel distance to the nearest hose is not greater than 25 m.

3) At least one portable extinguisher having a rating of 30-B:C shall be located on each industrial lift truck.

4.10.8.2. Standpipe and Hose Systems

1) Except as provided in Sentence (2), standpipe and hose systems shall be provided and installed in distilleries in conformance with Article 2.1.3.1.

2) Where a building is sprinklered in conformance with Article 2.1.3.6., small hose (38 mm) stations are permitted to be supplied from interior sprinkler piping.
