Be it ordained by the Sangguniang Panlungsod, City of General Santos, that:

Section 1. Title.— This Ordinance shall be known as “An Ordinance Establishing the General Santos City Liquid Nitrogen (LN2) Plant and Prescribing the Guidelines on the Operation Thereof”
Section 2. Definition of Terms. — As used in this ordinance, the following termsare hereby defined:

a. Liquid Nitrogen (LN2) – Nitrogen in a liquid state at an extremely low temperature which could instantly freeze anything it touches. It is used as coolant to preserve semen of livestock and in other cryopreservation;
b. Government Entity – includes, other Local Government Units, State Colleges and Universities, Bureaus, National Government Agencies and its instrumentalities;
c. Plant – refers to the closed structure where Liquid Nitrogen is produced, situated at Demo Farm in Brgy. Sinawal;
d. Non-Government entity – refers to organizations and offices that are not part of the government; private sector;
e. Air compressor – refers to the machine used to collect nitrogen from the surroundings to the collection tank through compression;
f. Air dryer – refers to the equipment where liquid nitrogen from the air collected are separated;
g. Nitrogen generator – refers to machine that generates 99.8% nitrogen from the surroundings;
h. Filter bank – refers to different stages of filtration that eliminate other elements aside from nitrogen gas before entering the nitrogen generator;
i. Water chiller – refers to the machine that is responsible for cooling the water;
j. Auto voltage regulator – a device that regulates the flow of electrical current;
k. Helium compressor – refers to the machine that produce cryogenic materials;
I. Electrical protection device – a digital circuit device that diagnose the electrical current entering the helium compressor;
m. Dewar – a designed container for collection of cryogenic material or liquid nitrogen;
n. Artificial insemination – refers to introduction of sperm into female reproductive organ for fertilization which is done in vivo.

Section 3. Production Operation. 

a. General requirements. —Installations shall be designed, constructed and installed in accordance with recognized pressure vessel, storage tank, piping and building codes and shall comply with the equipment manufacturer’s and the production site operator’s specifications.

Prior to its first use, commissioning shall be carried out only by authorized personnel and in accordance with a written procedure. A competent person shall validate the installation, as suitable for the duty within defined operating limits for a defined operating period. A person that should have such practical and theoretical knowledge and actual experience of the type of plant which he has to examine will enable him to detect defects or weakness. The purpose of the examination is to discover, and to assess their importance in relation to the integrity and function of the plant.

b. Safety Procedure. —Liquid Nitrogen can cause significant burns. Personnel Protective Equipment (PPE’s) like cryo – gloves , goggle and face mask are to be worn at all times when handling liquid nitrogen. When handling large quantities, a full length apron must be worn to prevent damage feet or shoes in case of large amount of spillage. Avoid wearing of short trousers and sando when inside the plant.

Dewars and all pressurized eqiupment must be taped solidly guard against pressure build-up by using a pressure relief valve or a venting lid. (Supplied by the Manufacturer and required by the supplier)

Nitrogen is not poisonous; the air is about 78% nitrogen (oxygen makes up about 21%, and trace gases the remaining 1%). However, if sufficient liquid nitrogen evaporate from a pressurized container into a poorly ventilated space it can reduce the oxygen. Personnel in that space are in critical jeopardy due to rapid oxygen deprivation. Rapid venting can cause rapid displacement of normal air, leading to a local concentration of nitrogen that will result to asphyxiation.

Notices and symbols shall be clearly displayed to be visible at all times on or near the tank, particularly at Access Points like the following:

THIS IS A LIQUID NITROGEN PLANT
EVERY ONE MUST OBSERVE:
NO SMOKING
NO HOT WORK
NO NAKED LIGHTS
NO STORAGE OF OIL, GREASE OR COMBUSTIBLE MATERIALS
AUTHORIZED PERSONS ONLY

Use only containers or vessels appropriated for liquid nitrogen or designed for extreme cold temperature products.

c. Dispensing and Transporting Liquid Nitrogen. — The transfer of liquid nitrogen from high pressure outside bulk storage containers to low pressure transportable vessels or Dewar containers is not allowed unless the low pressure container is fully designed and designated to accept high pressure material. Transferring of liquid nitrogen from high pressure container to incompatible containers is very dangerous.

Liquid Nitrogen are to be dispensed only into smaller Dewars which either have carrying handles.

Persons filling Dewars should wear full length pants or apron, and footwear that covers the entire foot, along with goggles, face mask and cryo-gloves. Persons filling must be in constant awareness of the filling operation.

The transport of Liquid Nitrogen or other Cryogenic Materials in open containers is not allowed. A wide-base Dewar which is stable on a wheeled cart qualifies as “on wheels”.

d. Training of personnel. – All personnel directly involved in the commissioning, operation and maintenance of storage systems shall be fully informed regarding the hazards associated with oxygen, nitrogen and argon and properly trained as applicable to operate or maintain the equipment.

Training shall cover the following subjects for all personnel involved in the operation like:

1.) Potential hazards of the cryogenic fluids
2.) Site safety regulations
3.) Emergency procedures
4.) Use of fire fighting equipment
5.) Use of protective clothing/apparatus including sets where appropriate
6.) First aid treatment for cryogenic burns.
e. Only farms, establishments, private companies and Non-Government Organizations (NGOs) accredited by the City Veterinarian’s Office with appropriate containers/dewar are allowed to withdraw Liquid Nitrogen.

Section 4. Logistical support. – The staff of the plant, and the operating or capital expenses shall be provided by the Local Government Unit of General Santos City, subject to budgetary, logistical and training requirements.

a. Duties and Functions. —The staff shall have the following duties and functions:

1.) Operate the Mini Liquid Nitrogen Plants 24 hours;
