1. Wet blasting. 2. Effective enclosures with necessary dust collecting equipment.

Monitoring, record keeping and reporting requirements:

a. Each time an abrasive blasting project is conducted, the Contractor shall log in ink or in an electronic format, a record of the following:

1. The date the project was conducted 2. The duration of the project; and 3. Type of control measures employed.

During field painting, adjacent surfaces below and around the work shall be protected with drop cloths, enclosures, tents, or other suitable means.

Upon completion of the work, the premises shall be left clean and presentable. Spent grit blast agents shall be removed from the work area daily.

During and after erection, shop painted surfaces shall be inspected and damaged surfaces to be touched-up or recoated shall be prepared and coated in accordance with the specification for the original undamaged coating.

Equipment nameplates and identification plates shall be protected from surface preparation and coatings. Those either coated or damaged by coating operations shall be replaced or reconditioned to the satisfaction of the Engineer.




9 of 24

All field applied and manufacturer supplied touch-up coatings and coating constituents shall be delivered to the job in original sealed containers bearing the manufacturer’s label.

For blasting operations inside the process building or where operating equipment may be damaged by blasting residue, the contractor shall either;

• Utilize a water blast method.

The Contractor shall not paint outside during windy conditions.

The Contractor shall take any special precautions necessary to protect:

• All valves, instruments, pumps, seals, bearing housing, motors and other sensitive areas (these shall be covered to prevent blasting material and paint from entering and damaging equipment.)

The Engineer shall approve the blasting methods used and the enclosure design and construction prior to any blasting work.

4.4 MATERIAL STORAGE

The Contractor shall store paint and painting supplies in approved ventilated, fire-proof cabinets, protecting the paint and supplies from any detrimental environmental effects.

Paints and thinners shall be stored under sufficient shelter to provide protection from direct sunlight, rain and extremes of temperature. Refer to manufacturer’s product data sheets for storage and shelf life. Smoking or open flames shall not be permitted within the storage areas. The Contractor post sign “No Smoking or Open Flame” and ensure suitable and approved fire protection equipment shall be within easy access.

5 WORKMANSHIP

All work shall be done by skilled workers qualified to perform the work in a manner comparable to the best standards of practice in that trade. All materials shall be evenly applied to form a smooth, continuous, unbroken coating free from sags, runs and other defects.

Contractor painting equipment shall be maintained in good working order and shall be comparable to that described in the coating manufacturer’s most recent application instructions. The equipment shall be thoroughly cleaned and inspected daily. Worn spray nozzles and tips shall be replaced. Effective oil and water separators shall be used and serviced on all air lines. Automatic cutoffs (deadman safety design) shall be used on blast pots.




10 of 24

All special or additional surface preparation shall be accomplished as outlined in the coating manufacturer’s most recent printed Application Instructions.

Before any surface is coated, it shall be cleaned of all dust, dirt, grease, loose rust, mill scale, oil and paint in accordance with the systems specified in this specification. Coatings shall not be applied to wet or damp surfaces, except in accordance with instructions of the manufacturer.

No coatings shall be applied when the air temperature is below 10°C or above 38°C or when the temperature of the surface to be coated is below 4°C or above 38°C or when the relative humidity exceeds 85 percent. Surface temperatures must be at least 3°C above dew point to prevent condensation. No coatings shall be applied if a predicted temperature of 2°C or lower is forecast within 24 hours of application unless the coating area is enclosed and heated per paint manufacturer’s recommendation.

No coating shall be done when the surfaces may become exposed to rain, fog or condensation or when it is anticipated that these conditions will prevail during the drying period, unless suitable enclosures to protect the surfaces are used. Where heat is necessary, it shall be supplied by the contractor and shall be of such type that it will maintain an air and coated surface temperature of 10°C (minimum) during the coating period and 32°C during the cure stage if hot forced air curing is recommended by the coating manufacturer.

Particular care shall be exercised to prevent the contamination of cleaned and coated surfaces with salt, acids, alkali, or other corrosive chemicals or reagents prior to application of primer or sucessive coatings. Any contaminants shall be removed and the surfaces shall be re-coated. Prepared surfaces shall not be left uncoated overnight without specific approval by the Engineer.

All brush applied coatings shall be of proper consistency and well brushed out to produce a minimum of brush marks. Enamel shall be uniformly flowed on. Edges shall be clean and sharp.

All coats shall be thoroughly dry before the succeeding coat is applied, following manufacturer’s instructions.

Paint coats as specified are intended to cover surfaces completely. If surfaces are not fully covered, further coats shall be applied. All finishes shall be uniform as to sheen, color, and texture.

Upon completion of the work, any remaining spillage, splatter or splash on adjacent surfaces such as glass, fixtures, floors or fittings shall be completely removed and the premises left in a clean and presentable condition. Used blasting materials, paint chips, or other debris are not to be washed into the plant trenches, but shall be swept and shoveled up and removed from site in accordance with the local ordinance and regulations.




11 of 24

Tests and Inspection Inspection tours of the work may be made at random by the Engineer or Owner to determine that surface preparation and coating application work is in conformance with this specification. a) The thickness of dry-film must be in achieved in accordance with SSPC PA2. b) The surface profile must be in achieved in accordance with ASTM D4417. c) The adhesion measure must be in achieved in accordance with ASTM D4541.
