SAFETY FIRST

Safety is situation or condition of being safe from undergoing or causing hurt, and injury. The complete mean is being "safe", the condition of being protected against physical, social, spiritual, financial, political, emotional, occupational, psychological, educational or other types or consequences of failure, damage, error, accident, harm or any other event which could be considered non-desirable. This can take the form of being protected from the event or from exposure to something that causes health or economical losses. It can include protection of people or of possessions.

In shipyard many metal plate, pipe, gas, crane, hight voltage current, and many big power equipment. Workers will be around those materials. Every day they will face the dangerous situation. That is the way shipyard must have one department to handle this situation. We can avoid the accident if it the destiny, but we can to change it to minimize the caution of the situation that can make injury or damage.

One principal that we have to remember is safety first. Before start to work, look around and make the condition safe from everything that can make dangerous. Remember!!! Safety is your self. Hope that condition same well with before.

It is important that companies understand the risks involved for work in confined spaces and the measures needed to ensure that work is planned and implemented properly. Workers must also be properly briefed on how they can work safely.

The employees of some shipyard are the most important assets to shipyard business. A proactive approach to Safety with quality training and briefing will ensure that employees and business are safer from the dangers of everything. It must take for regularly training and briefing. Generally, the new worker must get the safety briefing from safety officer before start work. After that the company must give the main safety equipment like helmet, safety shoes, goggle , ear plug, and overall .

All the shipyard safety officer, or project supervisor will conduct their own safety checks and briefing at the beginning of the day before carrying out any operations/work. Extra caution are given to special projects which maybe more dangerous.

Safety wise, i am sure workers are to be with helmets, safety shoes and all the equipments whether they are in yards or the terminal port.

Safety is always a number one in the shipyard because anything can happen. Being a new entrant doesn't mean that the importance of safety is not there, sometimes accidents do happen and its often beyond our control.

WATCH OUT MAN!!!!!!!!!!!!!!

Actually, The type of damage and injury that we can find in shipyard are explode some explosive thing, burned, poisoning of gas, radiation and fall down from the hight place. There are many procedure to make all of the damage under control. And many equipment must be stoked in shipyard to handle of safety situation, one of them is fire extinguished.

There are two main types of fire extinguishers: Stored pressure and generated pressure. In stored pressure units, the expellant is stored in the same chamber as the firefighting agent itself. Depending on the agent used, different propellants are used. With dry chemical extinguishers, nitrogen is typically used; water and foam are pressurized with air. Stored pressure are the most common type fire extinguishers. Generated pressure, or cartridge-operated extinguishers, contain the expellant gas in a separate cartridge that is punctured prior to discharge, exposing the propellant to the agent. These types as are not common, used primarily in areas such as industrial facilities, where they receive higher-than-average use. They have the advantage of simple and prompt recharge, allowing an operator to discharge the extinguisher, recharge it, and return to the fire in an reasonable amount of time. Unlike stored pressure types, these extinguishers utilize compressed CO₂ instead of nitrogen.

Fire extinguishers are further divided into handheld and cart-mounted, also called wheeled extinguishers. Handheld extinguishers weight from 2 to 30 pounds (1 to 14 kilograms), and are hence easily portable by hand. Handheld extinguishers exist in both stored- and generated-pressure types and contain all types of suppressants. Cart-mounted units typically weigh 50+ pounds (23+ kilograms), are almost always cartridge-operated, and typically contain either dry chemical, foam, or CO₂. (wikipedia)

Types of extinguishing agents

Dry Chemical (lyophobic colloid)

Powder based agent that extinguishes by separating the four parts of the fire tetrahedron It prevents the chemical reaction between heat, fuel and oxygen, thus extinguishing the fire.

• Monoammonium phosphate also known as ABC dry chemical, used on class A, B, and C fires. It receives its class A rating from the agents ability to melt and flow at 177 °C (350 °F) to smother the fire. More corrosive than other dry chemical agents.
• Sodium bicarbonate used on class B and C fires. Interrupts the fire's chemical reaction.
• Potasium bicarbonate (aka Purple-K), used on class B and C fires. About two times as effective on class B fires as sodium bicarbonate. The preferred dry chemical agent of the oil and gas industry. The only dry chemical agent certified for use in AR-FF by the NFPA.
• Urea complex and Potasium bicarbonate (aka Monnex), used on Class B and C fires. More effective than all other powders due to its ability to decrepitate (where the powder breaks up into smaller particles) in the flame zone creating a larger surface area for free radical inhibition.

Foams (lyophilic colloid)

Applied to fuel fires as either an aspirated (mixed & expanded with air in a branch pipe) or non aspirated form to form a frothy blanket or seal over the fuel, preventing oxygen reaching it. Unlike powder, foam can be used to progressively extinguish fires without flashback.

• AFFF (aqueous film forming foam), used on A and B fires and for vapor suppression. The most common type in portable extinguishers. It contains flour tensides which can be accumulated in human body.
• AR-AFFF(Alcohol-resistant aqueous film forming foams), used on fuel fires containing alcohol. Forms a membrane between the fuel and the foam preventing the alcohol from breaking down the foam blanket.
• FFFP (film forming fluoroprotein) contains naturally occurring proteins from animal fats to create a foam blanket that is more heat resistant then the synthetic AFFF foams.
• CAFS compressed air foam system) Any APW style extinguisher that is charged with a foam solution and pressurized with compressed air. Generally used to extend a water supply in wildland operations. Used on class A fires and with very dry foam on class B for vapor suppression.
• Arctic fire Is a liquid fire extinguishing agent that emulsifies and cools heated materials quicker than water or ordinary foam. It is used extensively in the steel industry. Effective on classes A, B, and D.
• FireAde a foaming agent that emulsifies burning liquids and renders them non-flammable. It is able to cool heated material and surfaces similar to CAFS. Used on A and B (said to be effective on some class D hazards, although not recommended due to the fact that fireade still contains amounts of water which will react with some metal fires).

Water

Cools burning material.

• APW (Air pressurized water) cools burning material by absorbing heat from burning material. Effective on only Class A fires, but has the advantage of being inexpensive, harmless, and relatively easy to clean up.
• Water Mist uses a fine misting nozzle to break up a stream of deionized water to the point of not conducting electricity back to the operator. Class A and C rated. Used widely in hospitals for the reason that unlike other clean-agent suppressants, it is harmless and non-contaminant.

Water Additives

• Wet Chemical (potassium acetate) extinguishes the fire by forming a soapy foam blanket over the burning oil (saponification) and by cooling the oil below its ignition temperature. Generally class A and K (F in Europe) only.
• Wetting agent Detergent based additives used to break the surface tension of water and improve penetration of Class A fires. Enables a 3 liter water extinguisher to achieve the fire fighting capacity of a 9 liter plain water type.

Fire extinguishers


To protect our eyes from damage, we will need goggle, to protect us from falling down we will need safety belt, to protect our ears from hight sound we need earplug. To protect our hand from burned, hot and injury we will need glove.

Thank you for your attention while reading my posting. I hope that you can satisfied with my posting here, understand it, and make your planning to prepare everything to take a vacancy in shipyard. I hope i can see you there.
