How to use AC in this hot season?

 Correct use of AC:

With the start of hot summer season and regular use of air conditioners, let's follow the correct method.

Most people have a habit of running their ACs at 20-22 degrees and when they feel cold, they cover their bodies with blankets. This leads to a double loss. How???

Did you know that our body temperature is 35 degrees Celsius? The body can easily tolerate temperatures between 23 degrees and 39 degrees. This is called human body temperature tolerance.

When the room temperature is too low or too high, the body reacts by sneezing and shivering.

When you run the AC at 19-20-21 degrees, the room temperature is much lower than the normal body temperature and this starts a process called hypothermia in the body, which affects blood circulation, thereby causing insufficient blood supply to certain parts of the body. sees Long-term disabilities such as arthritis can result.

When the AC is on there is mostly no sweat, so the body's toxins cannot get out, and in the long run there is a risk of many diseases like skin allergies or itching, high blood pressure etc.

When you run the AC at such low temperature, it keeps the compressor running at full power, even if it is 5 star rated, more power is consumed & it wastes money from your pocket.

What is the best way to run AC?? Set temperatures at 26 degrees or higher.

First setting the AC temperature to 20 - 21 will not give you any benefit, then It is always better to run the AC at 26+ degrees and keep the fan on slow speed. 28 plus degrees is ideal.

It consumes less electricity, and your body temperature is also within range, and there is no harm to your health.

Another advantage of this is that the AC will consume less electricity, the blood pressure on the brain will also decrease and the savings will ultimately help reduce the effects of global warming. How??

Let's say you save 5 units per night by running AC in 10 lakh houses at 26+ degrees, then we save 5 million units of electricity per day.

At the regional level this saving could be crores of units per day.

Please consider the above and do not run your AC below 26 degrees. Keep your body and environment healthy.

Compressed Gas Cylinders Safety

Dear Readers,

Industrial, manufacturing, repair shops, fabrication shops and construction operations require the use of compressed gases for a variety of different operations. Compressed gases present a unique hazard. Depending on the gas, there is a potential for simultaneous exposure to both mechanical and chemical hazards. 

Hazards include

• Fire & Explosion

• Missile hazard from broken cylinder heads

• Frostbite or gas injection under skin

• Impact from falling cylinders

• Poisoning     

• Asphyxiation     

• Over exposure 

Main Causes are inadequate training and supervision, poor installation, poor maintenance, poor storage, faulty equipment etc. 

We shall ensure at most safe precautions to create safe working environment to eliminate the risk of injury due to the compressed gas cylinders. The smart safety rules and controls are as follows.

• Inspect cylinders, regulators, flash back arrestors, hoses for damage and as per the standards before each use. Check cylinder & gas identification

• Use a cart/wheeled trolley or other secure means for moving - never carry or roll gas cylinders

• Grease or oils in areas where compressed oxygen is used can cause fire or explosion

• Use non-sparking tools for flammable gases

• Secure cylinders at work areas. Installation of caps on all cylinders

• Never refill or attempt to repair a gas cylinder

• Move leaking cylinders out of the offices/work areas – then vent all remaining gas.  Mark damaged cylinders “Damaged. Do not Use”

• Engineering controls such as gas cylinder storage areas, leak monitors, fume hoods, ventilation systems, sprinkler systems 

• Administrative controls such as inspections, training, audits, signage & labels, identification of authorized employees, safe operating procedures

• Proper personal protective equipment use

Personnel working with the compressed gas cylinders must be aware of the risks and follow safe work practices. Please take note on the identification of Hazards, required safety control measures, and communicate the information to the entire site crew.

Purpose of Admixtures

Dear Readers,

In continuation with Admixtures article, let us understand the functions

Functions of Admixtures

Concrete admixtures have various functions and they are as follows:

(a) To  increase  the rate  of strength development at early ages – calcium chloride is the most widely  used accelerator,                              

(b) To retard the initial setting time while pumping concrete over a long distance,

(c) To  increase the workability without changing the water content – pozzolana such as fly ash is used,

(d) To increase the strength,

(e) To  increase  the  resistance  to  freezing  and  thawing  – vinyl  resin  is  an  air entrainment admixture which is used for this purpose,

(f) To decrease heat evolution,

(g) To increase water tightness,

(h) To decrease capillary flow of water, and

(i) To decrease rate of bleeding and segregation. 

Chemical admixtures are various types and they are:

(a) Accelerating admixture – A substance that increases the rate of hydration of hydraulic cement, reduces the setting time, or in other words, increases the rate of strength development.

(b) Retarding admixture – A substance which delays the setting time of cement paste.

(c)   Water – reducing admixture – A substance which either increases the workability of freshly mixed mortar or concrete without increasing water-cement ratio or maintains workability with reduced water-cement ratio.

(d) Air – entraining admixture – A substance that causes air to entrap/Cd in the form of tiny bubbles in mortar or concrete during mixing to increase its workability and resistance to freezing and thawing.

(e)  Super plasticizing admixture   – A   substance that has very high workability with a large decrease in water content (at least) for a given workability. High range water reducing admixture (HRWRA) is also referred to as a superplasticizer.
