1.3 DEFINITIONS

1.3.1 Certified Industrial Hygienist (CIH)

As used in this section, refers to an Industrial Hygienist employed by the Contractor and is certified by the American Board of Industrial Hygiene in comprehensive practice.

1.3.2 Marine Chemist

The holder of a valid Certificate issued by the National Fire Protection Association in accordance with the "Rules for Certification of Marine Chemists," establishing him as a person qualified to determine whether construction, alteration, repair, or shipbreaking of vessels, which may involve hazards covered by NFPA 306 can be undertaken with safety.

1.3.3 Hazardous Areas

Hazardous areas must be defined as any area within 100 feet of active aboveground storage tanks, areas within 100 feet of leaking sections of fuel pipelines or other vapor sources, areas within 200 feet of the downwind side of potential vapor emission sources (i.e., pressure-vacuum vents or open vents on active tanks, leaking sections of pipelines), areas within existing tanks, and areas within a dike.

1.3.4 Hot Work Operations

Hot work, for work covered by this section, includes: flame heating, welding, torch cutting, brazing, carbon arc gouging, or any work which produces heat, by any means, of 400 degrees F or more; or in the presence of flammables or flammable atmospheres, other ignition sources such as spark or arc producing tools (except steel hand tools) or equipment, static discharges, friction, impact, open flames or embers, nonexplosion-proof

SECTION 33 01 50.60 Page 6 lights, fixtures, motors or equipment. Prepare tankbottoms for hot work in accordance with API RP 2207.

1.3.5 Personal Monitoring

Sampling of lead concentrations within the breathing zone of an employee to determine the 8-hour time weighted average concentration in accordance with 29 CFR 1910.1025. Samples must be representative of the employee's work tasks. Breathing zone must be considered an area within a hemisphere, forward of the shoulders, with a radius of 6 to 9 inches and the center at the nose or mouth of an employee.

1.3.6 Reproductive Hazard

A reproductive hazard is defined as any occupational stressor (biological, chemical, or physical) that has the potential to adversely affect the human reproductive process. For example, it is well known that central nervous system problems often occur in the offspring of mothers exposed to organic mercury during pregnancy. Therefore, based on the example cited, organic mercury can be classified as a reproductive stressor. Many reproductive hazards also cause other adverse health effects; for example, ethylene oxide is also known to be a carcinogen (i.e., produces cancer). Certain reproductive stressors can also have adverse effects on the male reproductive system. (If requested by the Contractor, the Contracting Officer will make available the Navy's standard on reproductive hazards.)

1.3.7 Flammable Liquid

Any liquid having a flash point below 100 degrees F and a vapor pressure not exceeding 40 psia at 100 degrees F.

1.3.8 Combustible Liquid

Any liquid having a flash point at or above 100 degrees F.

1.4 QUALIFICATIONS

a. To Be Considered Qualified: Show proof of having completed work on three previous projects.

b. See certificate requirements for personnel as specified in paragraph

CERTIFICATES.

1.5 QUALITY ASSURANCE

1.5.1 Modification of References

Except as modified herein, the work must conform with the recommendations of NFPA 326, API RP 500, API RP 2003, and API Std 2015. Where the word "should" appears in these publications, substitute "must."

1.5.2 Copies of Standards

SECTION 33 01 50.60 Page 14

3.1.1 Isolation From Piping

For tank cleaning prior to out-of-service inspection and minor cold repairs, close the double block and bleed isolation valves and remove the body cavity plugs from the valves. Monitor the body cavity for fuel and maintain the valves in this condition for the duration of the cleaning, inspection, or minor cold repairs, not to exceed one month. Secure the valves in the closed position with mechanical means. Perform lockout tagout procedures on the valves.

For ordinary cleaning prior to out-of-service inspection and hot work or when nozzles are not equipped with double block and bleed valves, or for outages lasting longer than one month, disconnect piping connected to the tank. Provide a solid-plate line blank between two flanges near the tank in accordance with ASME B16.48, or remove a valve or piece of pipe and provide a blind flange compliant with ASME B16.5 to isolate tank. Isolation means must be of sufficient strength to withstand pressure which might be exerted by the product being blanked off, and must be gasketed on both sides if blind flange is inserted between two flanges. Do not disconnect piping or valves until it is certain the line has been defueled.

Isolate all piping connected to the tank. Perform lockout tagout procedures on any valve remaining connected to the tank.

3.1.1.1 Thermal Relief

Evaluate thermal relief capability on active facility piping isolated from the tank. Should isolation means result in a segment of active piping unprotected from thermal overpressure, provide temporary means consistent with API Std 521 to relieve the overpressure. Consult with operators to determine existing relief pressures and set temporary relief means to ensure overpressure does not occur.

3.1.2 Lockout Tagout

Perform lockout tagout on all electrical circuits and sources of energy to the tank in accordance with EM 385-1-1 and NFPA 326.

h. An NFPA certified "Marine Chemist" or CIH has certified that the tank is safe for hot work, and that the required special precautionary measures have been taken due to the potential health hazard to the worker that still exists, even when the vapor concentration is well below the LFL. The Contractor must be responsible for reviewing the record drawing(s) of the tank to be cleaned.

i. People entering the area leave smoking materials such as cigarettes and flame-producing devices at a previously determined location.

j. When work involves handling and disposal of hazardous waste, the Contractor has a copy of 40 CFR 260, 40 CFR 261, 40 CFR 262, 40 CFR 263, 40 CFR 264, 40 CFR 265, and 40 CFR 266 in his possession.

Furnish two carbon-dioxide fire extinguishers of minimum 15 pounds capacity each, in the immediate vicinity of the work. Provide a continuous fire watch. CAUTION: Do not discharge high pressure carbon dioxide extinguishers where explosive vapors exist since the discharge can cause a spark which will ignite the vapors.

3.2.5.3 Disconnection of Pipelines

For normal tank cleaning prior to out-of-service (internal) inspection and minor cold repairs, close the double block and bleed valves on the tank nozzles connected to piping and remove the body cavity plugs from the bottoms of the valves and bleed the valves for the duration of the cleaning, inspection or minor cold repairs. Perform lock-out/tag-out procedures on the valves.

For cleaning prior to hot work or when nozzles are not equipped with double block and bleed valves, or for extended outages lasting longer than one month, disconnect pipelines connected to the tank. Provide a solid-plate blind flange between two flanges near the tank, or remove a valve or piece of pipe and provide a blind flange to prevent flammable material from entering the tank.
