History and color meaning of Helmet Safety

The use of safety helmets (Safety Helmet) starts from workers in a dock or shipyard. Before safety helmets or safety helmets are created they usually protect their heads using hardened dry asphalt which is dried in the sun. The purpose of this use is to cover and protect their heads from the threat of falling or falling objects on the deck of the ship they are building. Officially the first safety helmet was developed in 1912 at the Royal Worker’s Accident Insurance Institute in Bohemia.

In addition to the history of Safety helmets, the basic ingredients for making safety helmets also change along with the development of new and more effective material technologies. The following are the basic ingredients for making helmet safety from time to time:

1. Asphalt was dried before 1912
2. Thick canvas in 1919
3. Aluminum in 1938 (this material should not be used in electricity workers because it is dangerous and can be electrocuted)
4. Fiberglass in 1940
5. Thermoplastic in 1950
6. High Density Polyethylene or HDPE which is still used today.

Safety helmets are of two types, namely:

1. Safety helmet underground or tunnel mining workers. This helmet is in the shape of a wide edge and above is more prominent with a hanger or place for placing a flashlight.
2. Safety helmets used in mining areas or open industries. This helmet is just ordinary or more general.

The Meaning and Purpose of Helmet Safety Colors

The colors on the safety helmet are very striking and bright like yellow, white, orange, green, blue, red etc. The main purpose of the color of the safety helmet is that workers who use this safety helmet will be more easily seen if there are vehicles or heavy equipment that will pass so they are not hit.

But now safety helmets have their own color meaning. The following are some colors of safety helmets that reflect a person's position or position.

1. White safety helmets are usually used by managers, supervisors, engineers, and foremen.
2. Blue safety helmets are usually used by site supervisors, electrical, contractors or temporary supervisors.
3. Yellow safety helmet is usually used by sub contractors or general workers.
4. Green safety helmets are usually used by environmental inspectors.
5. Pink safety helmets are usually worn by new workers or interns.
6. Orange safety helmets are usually worn by company guests.
7. Red safety helmet is usually used by the safety officer who is responsible for checking the safety system that has been installed and functioning in accordance with the standards set.

Actually this safety helmet color difference classification is not yet clear. Maybe this applies after many people interpret and define it so that it becomes a tradition.

Usually the safety helmet color classification is different or not applicable in every country even on every site or project. For example, workers in oil mining, people who use yellow safety helmets are the Operation Department division which is considered the most important unit and consists of skilled Engineers. So for them, yellow hats are the highest status or class, while in yellow construction hats, the lowest class is general workers including cleaner.

Main Functions of Helmet Safety

1. The main function of using a safety helmet is to protect the head to avoid falling goods and others.
2. In using safety helmets there are several things that must be considered including:
3. Before being used, examine that the helmet is in good condition to use, fit and comfortable in the head (not loose and not too narrow), not damaged and deformed.
4. Use a safety helmet in the head properly (not tilted, not looking up, or looking down so that it covers the view or upside down).
5. If you are in a high place and windy conditions, chain strips or chin straps should be used to avoid flying safety helmets due to high winds.

The use of a safety helmet usually has a usage limit, the average age of use of a safety helmet is five years, but this is very dependent on the material used to make the helmet. If the use of a safety helmet is damaged such as being hit by a falling object or being hit by a collision, the helmet must be replaced as soon as possible with a new one. Do not use a safety helmet that has been damaged or damaged.

Every manufacturer of a safety helmet will state the maximum usage limit for the helmet. Check carefully. It should also be noted that the helmet that is finished is cleaned every day. This is done to avoid damage to the material due to sticking dirt. Because it could be dirt is a chemical or oil that can trigger damage to the base material on the safety helmet.

Ir. Soekarno The First President of Indonesia was a World Architect

In this article, let's try to analyze how Ir.Soekarno, a civil engineer can form a country the size of Indonesia, what is taught in the civil engineering department so as to create a mindset to make major changes, we know that ir. the first president of the Indonesian republic was civil engineering.

So what is the educational history of the First President of the Republic of Indonesia ...?

Soekarno was born with the name of Soesno Sosrodiharjo on June 6, 1901 in the city of Surabaya, East Java, Indonesia. The education he had taken was as follows:

1. HIS in Surabaya (boarding house in the home of Haji Oemar Said Tokroaminoto, veteran politician of Syarikat Islam founder).
2. HBS (Hoogere Burger School) graduated in 1920.
3. THS (the Technische Hoogeschool or the High Engineering Technical School which is now the Bandung Institute of Technology / ITB) in Bandung passed May 25, 1926.

If we look at the back ground of his education, we can know that in addition to learning about the world, in this case civil engineering is also balanced with strong religious knowledge, where the combination of the two sciences is finally able to produce an expert figure in a building that is identical to a change followed by the science of religion that is able to push the steel in carrying out every wish, task and great responsibility, we have no doubt that religion is able to turn despair into enthusiasm, turn pessimists into optimistic, sincere in fighting and able to face every obstacle so that we can realize what is our goal, we can see that this time with Iranian president Ahmad Denajed who has the technological ability accompanied by strong religion so we can see a very powerful result, with each community able to build sincerely without feeling suspicious of lying by jaj government.

Why is civil engineering so closely related to change? some of the following may be an illustration:

1. The government in managing and developing a city will start it first by doing infrastructure development as a means of other changes both in terms of economy, culture and other matters.
2. The moral of the community can be good so that it can carry out activities that are useful for the country can be started from places of worship which of course require civil engineering to play a role.
3. In civil engineering, in addition to learning how to build, it is also learned how to manage or other languages ​​to manage an activity so that it can produce a job with good quality.
4. Civilization of a nation is often depicted by buildings that it has like Indonesia with Monas, Malaysia with the Petronas Tower, America with a statue of Liberty, Netherlands with a clock tower, Saudi Arabia with a haram mosque and Ka'bah, all of which are certainly closely related to civil engineering.
5. Etc.

So the education of Ir. Soekarno in the Department of Civil Engineering is a big capital for the establishment of a great country that might become a nation prepared by God to lead the world in its time.

So the responsibility of the next generation of civil engineering is to continue and be an inspiration for the changes that have been anticipated by all Indonesians, the change does not occur from members of the House of Representatives or the Government, it will be very difficult, changing a country must begin with each person because with a collection The person automatically in a larger scope will change the country to be good.

Which Architect vs Drafter is more Expert and Smart

It does not mean to demean the architect or drafter profession but here we try to compare the two as evaluation material to get better. yes ... let us answer together questions about Architects VS Which Drafter is more expert and smart? why this question can arise, of course there are many events experienced by drafters or architects so that there are parties who feel disadvantaged or benefited. Well ... please disclose all the information here, maybe it can be more plong and get responses from our other colleagues, as a start here are some things that might enter it.

Complaints from a Drafter Viewing Point to Architects

1. Those who have drafter ideas, who draw drafter but who get the name of the architect.
2. How come the architect can't draw using computer software, is it even better when you come. This may happen to senior architects who do not follow and learn the latest technology, especially in the field of computerization.
3. what else? ... please discuss here.

Complaints from the Architect's Viewpoint on Drafter

1. How come the drafters take over the work of the architect, making the building design to the community directly.
2. This draft is not the picture according to the architect's idea, at will.
3. what else? ... please discuss here.

The essence of the problem lies in the criteria for evaluating one's expertise, we know that in Indonesia there are many who measure something based on a diploma, even though we don't know what someone is like at school first, is a lazy person who often cheats on the theme or is it really diligent and clever, plus the name of that time continues to run, after school there may be those who continue to study independently so that they continue to develop into great personalities, there are also those who stop learning so that their abilities are stuck. So the expert or smart problem cannot be measured by a formal degree, the school is only helping to improve skills, then depending on each individual wants to move forward or not, so a suggestion for drafters or architects to work well to produce the best work, don't forget continue to study independently or at school & nbsp; so that they can become the greatest according to their respective fields and professions.
