certified by test procedures in 1.3, intact shopprimer may be
retalned provided the same epoxy coating system is used.
The retained shopprimer shall be cleaned by sweep blasting,

high-pressure water washing or equivalent method.
If a zinc silicate shopprimer has passed the pre-qualification
test of 1.3 as part of an epoxy coating system, it may be
used in combination with other epoxy coatings certified
under 1.3, provided that the compatibility has been
confirmed by the manufacturer by the test in accordance
with 1.7 of appendix 1 to annex 1 without wave movement.

2.4.3 Safety regulations for painting work
2.4.3.1. General prevention for surface preparation and painting application:
• Before painting:
-

Should be trained when starting paint work

-

Know all of safety procedures and place put necessary equipments if accidents

happen

-

Read and understand all of safety data and technique of products

-

Know all of dangers

-

Equipped enough individual safety equipments

• Painting process:
-

Always using individual tools checked (under standard)

-

Rightly use tools and equipments to avoid causing accidents

-

Should take a rest if work beyond painters’ strength

• After painting:
-

Close all tanks

-

Know how to clean equipments

-

Keep paints and solvents which have not been used in safety (storage)

-

Throw rubbish in dustbin regulated (harmful rubbish)

-

Clean individual safety tools and preserve to avoid contamination

-

Individual cleanness with water and soap

2.4.3.2. Painting safety work:
Painters have to understand symbol regulated by paint maker on painting can.
When working, painters prevent their skin touching directly from paint. Pay
attention to special paint.
• Equipped enough safety equipments, safety clothes and other safety conditions
• There must have a person being on duty above while another working inside
tank. Do not use 110V or 220V bulbs, explosion proof lights used not over
24V.

- Wear respirator with mechanical breather
- Do not assign weak strength workers to work inside tank
• Should open ventilation cover and gauge air volume before working inside
tank

196


COATING TECHNICAL FILE

• Do not weld, cut or heat near painting area in tanks with solvents vaporizing
fast (min. 5m). Continually use electrical ventilating blower 5m distance
from tank hatch.
• Should equip firm scaffolds, safety belts for working on high place.
• Should wear insulated gloves when use electrical machine to rub rust. Should
break circuit if move electrical machine to another position.
• Mixing types of paint with multi-components under correct rate of maker
• Use paint mixer between coats, steel surface temperature should comply with
Technical Instruction Procedure of painting types which paint maker sends to
shipyard. Should not mix solvents with paint unless paint maker or shipyard
technical staff instruct or accept.
• No smoking and prevent flammable abilities during painting work
• Painting types should have instructions before usage. Do not use paints with
vague origin.
• Tidy up instruments after working. Should put clouts with oil, paint in metal
container with cover, and put in correct places.
2.4.3.3. Necessary regulations:
• Scaffold:
-

Scaffold structure is durable, safety and easy to approach working surface:
Distance between the working surface and scaffold should be 150mm÷
300mm, (prevent hitting between circuit breaker and steel plate); Distance
between scaffold surfaces should be 30mm÷ 50mm (prevent hitting), which
makes advantage conditions for clearing as well as checking.

-

When painting inside tank, scaffold should meet demands as follows:
§ Max. limit points contact with tank surface.
§ Scaffold should be clean to avoid dust sticking on wet coats or damage
painting surface when removing
§ Use rubber to cover scaffold’s metal leg in order not to emit spark
when moving

• Lighting:
-

Always supply enough necessary lighting during surface preparation, painting,
inspection.

-

Use light under 24V: prevent fire, explosion; protection net and connect
through insulated transformer. Electric wires have to be firm; do not have
scrapes, connection positions should be covered firmly in order not to emit
spark.

-

Put switches outside, distance from tanks and the switches should be covered
in order not to emit spark

197


COATING TECHNICAL FILE

• Ventilation:
-

Good ventilation inside tank to reject solvents vapor and prevent forming mix
between solvents and air. Ventilation blower should be connected through
insulated transformer.

-

Normally, ventilation is carried out by suck pipe at tank bottom and connected
to ventilation blower on board. Air rotating flow of blower should be large to
vapor solvents and meet the requirement of health, safety.

-

Workers working inside tank should be equipped breathing mask. Supply
enough air for breathing. Balance between input and output air should be
adjusted suitably by blower in order not to wet paint during painting. Need to
continue ventilation after finish painting until solvents vapor completely
outside tank.

• Fire and explosion protection:

-

Absolutely avoid creating fire in painting area such as not be welded, cut,
smoke and works can emit spark in 15m limited area surrounding painting
work.

-

Only use painting equipments such as lights, switches, electric cables,
ventilation blowers etc. which belong to types of fire and explosion protection
equipments and do not emit spark. The equipments should be checked and
accepted by Safety Department.

-

Electric painting sprayer should be grounding.

-

Do not lengthen and make joins inside tank to avoid electrical leakage. Do not
put plugs inside tank.

-

Workers working inside tank should be equipped rubber sole shoes, safety
belts, breathing masks and other necessary safety tools.

-

Arrange at least 2 persons when working inside tank

-

After painting, tank is ventilated to assure safety for next stages

-

Do not arrange works which can emit spark during painting and after finish
painting, paint has not quietly dry at position near painting area (Min. distance
is from15m)

• Other regulations:
Beyond above regulations, procedures and other safety works regulated by
shipyard have been carried out strictly as follows:
-

Working on high place need to use firm chair, and workers must wear safety
belts.

-

If working inside tank, there must have person on duty inside, outside to solve
problems such as choking, paint sickness.

-

Before painting inside tank, should register production department to assign
work conveniently and register safety department to survey. After the two
departments sign to confirm safety condition, painting work are carried out.
Safety department should define dangerous area by signposts “Dangerous

198


COATING TECHNICAL FILE

area” and absolutely prohibit working in the area until safety department allow
removing signposts and continue working.
2.4.3.4.

Preliminary method in case of emergency:

-

Clouts soaking in paint is collected into pile, so they can burn. It should be
collect in casks which are difficult to burn have covers.

-

When paint shoot into eyes or skin, must wash by clean water many times,
after that go to medicine department to check.

-

After painting, gargle with clean water, wash hand by soap and water or
industrial detergent, do not use solvent for washing.

-

3.

In case paints burn, use CO2 fire-extinguish bottles or dry sand, do not use
water.

If painting smell make workers faint, bring them to clean and clear area for
recovering gradually, do not give artificial respiration.
