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

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

- Put switches outside, distance from tanks and the switches should be covered

in order not to emit spark
