Fire hazard in summer season

The temperature is very high in summer season and this condition will favor the Fire Hazards. This hazard is more during day time, especially in the noon hours.

The severity is more in Chemical and petrochemical industries due to the huge quantity of flammable solvents storage and handling operations. Following are prime reasons for Fire hazards in summer.

1.      Due to the high temperature in summer, solvent will evaporate vigorously and form explosive atmosphere around the flammables storage area.
2.      Due to hot condition of atmosphere in the summer, generation of sparks is also very higher than other seasons.
3.      You are all well aware the static electricity hazard, human body is a major ignition source.
4.      Due to the hot condition in summer, even all combustible materials also get dried and capable to ignite rapidly.

Hence, request all to take extreme care in storage and handling of Flammable solvents. The following are the few precautions to prevent fire hazards at workplaces.

1.      Cool storage tanks with water once a day using drip system/ sprinklers/ by spraying.
(If possible provide gunny bag lining on tanks to keep wetness for a long while).
2.      Provide insulation to Low boiling solvent storage tanks.
3.      Minimize/ avoid storage of solvents in Drums.
4.      Minimize the manual handling of flammable solvents.
5.      Don’t keep solvent drums or containers under direct sun light.
6.      Do not accumulate combustibles at work place and in the premises.
7.      Remove dry grass in the premises and around the compound wall.
8.      Keep clear access to Emergency exits & Emergency equipments.
9.      Ensure no leakages from pump seals and from others sources.
10.  Keep close the manholes of storage tanks, receiving tanks and other containers.
11.  Provide Flame arrestors to all the vents of Storage tanks.
12.  Take all precautions to prevent ignition generation due to Electrostatic hazards.

 Be Alert 

Heat Stress

There are two main ways in which our bodies produce heat:
1.     Metabolic Heat - the body generates heat through the digestion of food, work and exercise.
2.     Environmental Heat - body absorbs heat from the surrounding environment, whether it is the hot sun or a hot room.       
There are three methods in which our bodies can be cooled.
1.     Convection - is the transfer of heat through the circulation of air.
2.     Evaporation - process which occurs when a liquid changes into a vapor.
3.     Radiation - heat is naturally emitted from the body surface.
·      Acclimation - the biological process through which our bodies adapt to the environment -- basically  
getting used to the heat. 
·      Air Temperature - heat flows from warmer objects to cooler objects.
·      Air Movement - moving air speeds the evaporation process.
·      Humidity - the amount of water vapor in the air affects the rate of evaporation.
·      Clothing - the type of clothing affects the amount of heat our bodies absorb and retain

1.     Heat Rash - also known as Prickly Heat, occurs in hot, humid environments where sweat can't easily evaporate from the skin.  
·                     This condition produces a rash which in some cases causes severe pain. 
·                     The procedures to prevent or minimize this condition is to rest frequently  in cool places and bath regularly ensuring to thoroughly dry the skin.
2.     Heat Cramps - painful muscle spasms that result from the loss of salt and electrolytes due to excessive sweating. 
·                     The cramps will usually affect the stomach, the arms and legs. 
·                     This condition can be treated by drinking fluids containing electrolytes such as calcium, sodium and potassium. 
·                     This condition usually precedes heat exhaustion. 
3.     Heat Exhaustion - is a state brought on by the loss of fluids lost during excessive sweating. 
·                     –Individuals with heat exhaustion still sweat, but they experience extreme weakness and may even collapse. 
·                     –They may experience nausea and headache.  Their skin is clammy and moist, their complexion is usually pale and the body temperature is usually normal or slightly higher. 
·                     –This condition is best treated by taking the patient to a cool place, applying cool compresses, elevating the feet and giving the individual plenty of fluids.
4.     Heat Stroke - is a severe medical emergency which could result in death. 
·                     –Heat stroke results when the body's core temperature gets too high and the body is no longer able to cool itself. 
·                     –An individual suffering from heat stroke will have hot and dry skin, their pulse will be high and their blood pressure will fall. 
·                     –This condition must be treated by immediately cooling the victim's body with water or wrapping them in cool wet  sheets. Immediately seek medical attention.
·        Acclimation - accustom yourself to the weather prior to long durations of physical activity.
·        Maintain Body Fluids - Fluid intake must be maintained throughout the course of physical activity.
         Do not rely on thirst as an indicator of dehydration because your body loses water faster than you realize.
         Alcohol should be avoided because it is a diuretic, which increases dehydration and can interfere with heat loss.

· Proper Diet – Eat light and stay away from heavy foods. They increase metabolic heat production and also increase water loss. Eat smaller, well-balanced meals more often.
· Rest Periods - Pace your work activities at a slower rate during high temperatures and take frequent rest periods in a shaded area and drink plenty of fluids.
· Dress Light – Lightweight, light-colored clothing reflects heat and sunlight and helps your body maintain normal temperatures.
       Wear loose-fitting clothes such as cotton which lets air move over your body.

       Wide brimmed hats should also be worn.
