Dehydration is a major factor in most heat disorders. Warmer months of the year can be especially dangerous, no matter what type of mine you’re in.

The average body loses approximately 2½ quarts of sweat per day.

But when you’re performing strenuous work, the body can lose up to 1½ quarts of sweat per hour.  It is essential to drink more than is needed to satisfy thirst.

Salt Replacement
Sweat not only contains water, but also salt and other electrolytes.

The body needs a certain amount of salt to function properly, but salt tablets are not recommended because of stomach irritation, nausea and vomiting.  

Each mine worker should drink normal water throughout the day, but may drink an electrolyte solution after in a hot environment, if desired.

Individuals on a salt restricted diet or those persons being treated for high blood pressure or heart problems must NOT try to replace salt without the advice of their physician.

Recommended Protective Clothing
Loose fitting clothing made of light cotton allows sweat to evaporate and transfer heat better than tight fitting synthetic fibers.

Safe Work Practices
Watch out for the safety of coworkers. Take scheduled breaks in cool areas; employees should be provided with access to shade.  Drink plenty of cool water.  

Supervisors should consider scheduling the hottest work for the coolest part of the day, assigning extra workers to high demand tasks.

To reduce the body’s work load, try to use a wide variety of work saving devices such as power tools, hoists or other lifting aids.  

Water should always be provided in sufficient quantities throughout the day. 

ALWAYS STAY SAFE!
