KNOW THE MEANING OF VARIOUS COLOUR CODING USED IN FLOOR MARKING !

You might have seen industrial floors marked with various colored strips. Some of the strips are colored yellow and black, red and white, and so on. In this article, we will discuss the meaning of various colored strips that are used for floor marking. 

Floor marking is the process of using visual indicators such as lines, shapes, and signs on floors to make a space easier for people to navigate. These indicators divide spaces, highlight hazards, outline workstations, and storage locations, direct traffic, and convey important safety or instructional information. These markings are done as per OSHA (Occupational Safety and Health Administration) standards.

 

These markings are done for Organizational Improvement, Finding First Aid Equipment, Personal Protection Equipment, Navigation Assistance, Placement of Objects, Traffic Direction, etc. In short, these markings are done to keep the working environment safe and organized.

 

Different color coding is used to convey different messages. However, the industry can define its own color-coding. Following are the most commonly used color coding used.

Yellow Floor Tape

Yellow tape (or paint) should be used for all normal foot traffic going through a passage (both indoor and outdoor) as well as vehicle traffic.

White Floor Tape

White tape should be used for anything related to facility equipment, fixtures, racks, carts, and things of this nature. This helps people to alert people about their availability and lets people know where to put them when they're done using them.

Blue, green and/or black

Materials and components, including raw materials, work-in-progress and finished goods.

Orange Floor Tape

Materials in inspection

Red Floor Tape

Locations where defective products, scrap materials, or items in the facility that need to be reworked are stored.

Red & White Floor Tape

Any area that must be kept clear for safety or compliance. Areas around fire extinguishers, emergency eyewash stations, electrical panels, or fire lanes.

Black & White Floor Tape

Areas that need to be kept clear for general operations. Not to be used for emergency areas.

Black & Yellow Floor Tape

Areas that may expose employees to special physical or health hazards.


Floor markings have been proven to improve visual communication within facilities, while also benefiting overall facility safety. So, now you know the meaning of various color coding tapes used in the industry.

KNOW WHAT IS SENSEX AND NIFTY !

We daily hear words like "Sensex" and "Nifty" when we watch the news. These words are also related to the market but have you ever imagined what is the meaning of Sensex and Nifty? In this article we will understand the meaning of these two words with respect to the economy. 

There are thousands of listed companies in the stock exchange (Stock exchanges allow investors to buy and sell shares of a company among each other in a regulated and legitimate space.) in India. And, it is not at all easy to track every single stock. Therefore, a smaller sample is calculated which acts as a representative of the whole market. This small sample is called Index (in other words, indicator) and it helps in the measurement of the value of a section of the stock market. The index is computed from the prices of selected stocks. 

Sensex and Nifty are the two important indicators that are used to measure the behavior of the market. These market indices are known as a standard for portfolio performance. SENSEX (Sensitive Index) and NIFTY (Net Index of Fifty) are the benchmark index of India.

SENSEX:

Sensex, also called BSE 30, is the market index consisting of 30 well-established and financially sound companies listed on the Bombay Stock Exchange (BSE).BSE can revise this list of 30 with respect to time. So, if Sensex fluctuates, it reflects on the economy as well. For example, if Sensex goes up people become more interested in buying stocks because they think that economy is going to grow. But, if Sensex goes down, people tend to stop investing in the economy.

Let us understand it with an example, it is like trying to determine the ‘intelligence’ of a class of 500 students across various courses by taking the average marks of Top 30 students. The average result might be good but this may not necessarily be so. For better results we need to compare the averages across a period of time, or across classes as it is more helpful rather than looking at the average as a stand-alone factor.

NIFTY:

Nifty, also called NIFTY 50, is the market index consisting of 50 well-established and financially sound companies listed on the National Stock Exchange of India (NSE). Nifty Index constitutes of 50 companies that are considered to be the nation's economy movers and shakers. Each of the 50 companies contributes some weightage to the Nifty Index and its fall and rise indicate the condition of our economy.

It is just like the fuel indicator of your vehicle. When the fuel Indicator is in the Red zone, you understand that your fuel tank is about to be empty and you need to refill it or else your vehicle will stop running. In the same way, when you are filling up your tank and the Indicator turns full in Green zone, you understand your tank is full and you should stop filling it or else it will spill out of the tank.

WHY DO WE NEED THESE INDICATORS?

The rise and fall of an index would reflect the composite performance of all these companies, and in turn it is the representative of the whole market. It is the barometer of the economy. Indices can be constructed to track the performance of stocks, bonds, currencies, volatility, prices amongst many other things.

KNOW HOW TO DECODE GRADE OF GRINDING WHEEL !

Grinding is an abrasive machining process that uses a grinding wheel as the cutting tool. A grinding wheel is a precision tool with thousands of cutting points on its surface - abrasive grains that are held in place by a bond matrix (hence these are known as bonded abrasives) and separated by pores. When the wheel is in use, the abrasive grains cut into the material that is being ground, removing the unwanted surface material in small chips.

There are various grades of grinding wheels available in the market and every grinding wheel has its grade written on it. But have we ever thought what these grades mean? We will decode the grade of the grinding wheel in this article.

When selecting the perfect wheel for your project, it is important to know the grade of that grinding wheel. Every grinding wheel is marked by the manufacturer with a stencil or a small tag. The manufacturers have worked out a standard system of markings as shown in the figure below. For example use a wheel marked A36-L5-V23. The A refers to the abrasive which is aluminum oxide. The 36 represents the grain size. The L shows the grade or degree of hardness, which is medium. The 5 refers to the structure of the wheel and the V refers to the bond type.

ABRASIVE TYPE:

There are 4 main types of abrasive grains available for grinding wheels, these are Ceramic Aluminium Oxide, Silicon Carbide, Zirconia Alumina, Aluminium Oxide.

ABRASIVE GRAIN SIZE:

Abrasive grains are selected according to the mesh of a sieve through which they are sorted. For example, grain number 40 indicates that the abrasive grain passes through a sieve having approximately 40 meshes to the linear inch. A grinding wheel is designated coarse, medium, or fine according to the size of the individual abrasive grains making up the wheel.

GRADES OF HARDNESS:

The grade of a grinding wheel designates the hardness of the bonded material. Listed below are examples of those grades:
A soft wheel is one on which the cutting particles break away rapidly while a hard wheel is one on which the bond successfully opposes this breaking away of the abrasive grain.

STRUCTURE:

Bond strength of a grinding wheel is not wholly dependent upon the grade of hardness but depends equally on the structure of the wheel, that is, the spacing of the grain or its density. The structure or spacing is measured in number of grains per cubic inch of wheel volume.

BOND TYPE:

This means how the wheel holds the abrasives; affects finish, coolant, and minimum/maximum wheel speed.

So, now you know how to read the grade of grinding wheel. Thank you for reading this article.
