NOTE - THE NOTED DISAPPROVED ITEMS MAY NOT CONSTITUTE A COMPLETE LIST OF VIOLATIONS. THE DESIGNER IS TO CONDUCT A COMPLETE RE-REVIEW OF THE PLANS FOR ADDITIONAL VIOLATIONS OF THE STANDARD COMMENTS AND INCORRECT INFORMATION PRIOR TO RESUBMITTING.
System plans must be picked up within 30 days. All system plans left longer than 30 days will be discarded as abandoned.

I just spoke with Kay telling her you have decided not to have stored nitrogen on premises. She will approve the plans if you will reply to this e-mail stating explicitly that you "will not have stored nitrogen on the premises."

Subject: FW: size of West Dewar for liquid nitro
See Harry's info below. IF we get static for 10 liters of liquid nitro, we can take it away from them and say (truthfully) that we don't use it there anymore. Will that work?

10 liters. We should remove it as they never request that it be filled.

Subject: size of West Dewar for liquid nitro
Can you help me to identify the size of the Dewar used at West. We're getting all sorts of grief from the fire dept because we'll have liquid nitro at Roundhouse. They want us to put in extra ventilation!
Anyway, if you can look up the size of the unit, I can get them the info. This is holding up our ability to get a permit9

no location of storage and use reported at this time.|
Compressed gas containers, cylinders and tanks shall comply with IFC 2009, as amended, SECTION 3003 GENERAL REQUIREMENTS
Inert cryogenic fluids, including argon, helium and nitrogen, shall comply with CGA P-18.
Storage, use and handling of cryogenic fluids shall comply with chapter 32.
Indoor storage of portable containers shall comply with the provisions applicable to the type of fluid stored and Sections 3188.8.131.52 through 3184.108.40.206.
Portable containers shall comply with Section 3203.1.
Cryogenic fluids in portable containers stored indoors shall be stored in buildings, rooms or areas constructed in accordance with the International Building Code.
Storage areas shall be ventilated in accordance with the International Mechanical Code.
|Attention||THE CHEMICAL INVENTORY, AS DECLARED, DOES NOT EXCEED THE ALLOWABLE THRESHOLDS FOR OXIDIZING GAS OR CRYOGEN INERTS, AS DEFINED BY 2009 IFC TABLE 2703.1.1(1) AND/OR 2703.1.1(2).
THE CHEMICAL INVENTORY, AS DECLARED, DOES NOT EXCEED THE ANNUAL HAZARDOUS MATERIALS PERMIT THRESHOLD FOR OXYGEN OR CRYOGEN NITROGEN.
This facility is not required to enroll in the CSFD annual permit.
This facility is not required to complete a hazardous materials inspection for permit
THIS FACILITY IS REQUIRED TO COMPLET A HAZMAT INSPECTION FOR CONSTRUCTION DUE TO THE CRYOGEN INERT NITROGEN STORAGE & USE - VENTILATION REQUIREMENTS.
|Disapproved||MECHANICAL CODE 502.9.3
Storage areas for stationary or portable containers of cryogenic fluids in any quantity shall be ventilated in accordance with Section 502.8
Indoor areas where cryogenic fluids in any quantity are dispensed shall be ventilated in accordance with the requirements of section 502.84.4 in a manner that captures any vapor at the point of generation.
EXCEPTION: Ventilation for indoor dispensing areas is not required where it can be demonstrated that cryogenic fluids do not create harmful vapors.
* Identify location(s) of storage and dispensing use.
* Delineate and declare compliance with the above requirements.
* See ventilation requirements |
Cryogenic fluids in portable containers stored indoors shall be stored in buildings, rooms or areas constructed in accordance with the International Building Code. Storage areas shall be ventilated in accordance with the International Mechanical Code.
Indoor storage and use areas and storage buildings shall be provided with mechanical exhaust ventilation or natural ventilation in accordance with the requirements of Section 2704.3 or 2705.1.9. When mechanical ventilation is provided, the systems shall be operational during such time as the building or space is occupied.
Indoor storage areas and storage buildings shall be provided with mechanical exhaust ventilation or natural ventilation where natural ventilation can be shown to be acceptable for the materials as stored.
Exhaust ventilation sys-tems shall comply with all of the following:
1. Installation shall be in accordance with the Interna-tional Mechanical Code.
2. Mechanical ventilation shall be at a rate of not less than 1 cubic foot per minute per square foot [0.00508 m3/(s o m2)] of floor area over the storage area.
3. Systems shall operate continuously unless alternative designs are approved. A manual shutoff control shall be provided outside of the room in a position adjacent to the access door to the room or in an approved location. The switch shall be a break-glass or other approved type and shall be labeled: VENTILATION SYSTEM EMERGENCY SHUTOFF.
4. Exhaust ventilation shall be designed to consider the density of the potential fumes or vapors released. For fumes or vapors that are heavier than air, exhaust shall be taken from a point within 12 inches (305 mm) of the floor. For fumes or vapors that are lighter than air, exhaust shall be taken from a point within 12 inches (305 mm) of the highest point of the room.
5. The location of both the exhaust and inlet air openings shall be designed to provide air movement across all portions of the floor or room to prevent the accumulation of vapors.
6. Exhaust air shall not be recirculated to occupied areas if the materials stored are capable of emitting hazardous vapors and contaminants have not been removed. Air contaminated with explosive or flammable vapors, fumes or dusts; flammable, highly toxic or toxic gases; or radioactive materials shall not be recirculated.
** Resubmit plans delineating compliance with above|
|FYI||Cryogen Liquids --containers shall not be located in areas where:
they can be overturned due to operation of a door; they are in the direct path of egress
they are subject to falling objects;they can become part of an electrical circuit; or open flames and high temp. devices can cause a hazard..
|FYI||The hazards associated with liquid nitrogen are exposure to cold temperatures, which can cause severe burns; overpressurization due to expansion of small amounts of liquid into largevolumes of gas in inadequately vented equipment; and asphyxiation due to displacement of oxygen in the air in confined work areas.
If oxygen-deficient atmospheres are suspected or can occur, use oxygen monitoring equipment to test for oxygen-deficient atmospheres.
Review the liquid nitrogen Material Safety Data Sheet (MSDS).|
|FYI||Visible hazard identification signs in accordance with NFPA 704 shall be provided at entrances to buildings or areas in which cryogenic fluids are stored, handled or used.
Stationary and portable containers shall be marked with the name of the gas contained. Stationary above-ground contain-ers shall be placarded in accordance with IFC Sections 2703.5 and 2703.6.
Portable containers shall be identified in accordance with CGA C-7.
Extremely cold liquid and gas under pressure.
Can cause rapid suffocation.
May cause severe frostbite.|
