HAZARDOUS AREA LIGHTINGS – ENSURE WORKPLACE SAFETY (GUEST POST)

What is a Hazardous Area?

A hazardous area can be defined as any place in which an explosive atmosphere may occur. The reasons of why hazardous areas exist mainly include flammable gases or combustible dust. If adequate amount of flammable substance is mixed with oxygen, an ignition source appears that is sufficient to cause an explosion. Explosions caused can lead to serious injuries, extensive damage as well as loss of life. Presently there are many industrial facilities with hazardous areas, such as petrochemical refineries, chemical plants, and certain kinds of coal mines.

How can Hazardous Area Lighting Help?

Various equipment is used and measures taken by different organizations over a period of time to prevent explosions in a hazardous area, such as, Intrinsic Safety measure, Increased Safety measure, and Explosion-Proof Enclosures measure to ensure safety of employees working in hazardous areas. However, the equipment that has really proved helpful in fighting the explosive atmospheres from the start includes hazardous area lighting.      

Hazardous area/ location lighting is a type of lighting that is designed to be resistant to hostile climatic and atmospheric conditions. There are many types of hazardous location lighting that have been used over a period of time in hazardous environments, such as LED Lighting, Fluorescent, and Induction. However, advances in technology have brought about many changes and improvements in lighting technology for hazardous locations. Let’s have a look at how these changes developed.

 

Developments in Hazardous Area Lighting

The first ever hazardous location lighting was developed in the coal mining industry. In the early 1800’s many different inventors, such as Dr. William R. Clanny, and Sir Humphrey Davy, developed means of shielding miners from explosions caused by the lamps they carried. The most commonly used light of these was the “Davy lamp”, developed by Sir Humphrey Davy in 1815. However, soon after, electric lighting was introduced which is similar to what exists even today. Within the petrochemical industries the initial electric light sources that were used were incandescent lamps in explosion-proof housings.

After that as the technology further developed, HD fixtures were introduced into hazardous areas in the year 1940. Also, the developments in LED technology started taking place in the early 20th century. Since then the lighting technology has now advanced to its present state of using abundant of proven safety techniques and most available light source technologies. In the past few years developments in solid state lighting have also added a new source for general lighting applications.

STAY OUT OF ABANDONED MINES!

 

“Stay Out–Stay Alive” is a national public awareness campaign designed to warn children and adults about the dangers of exploring and playing on active and abandoned mine sites.
Every year, dozens of people are injured or killed in recreational accidents on mine property. MSHA launched “Stay Out–Stay Alive” in 1999 to educate the public about the existing hazards. The campaign is a partnership of more than 70 federal and state agencies, private organizations, businesses and individuals.

 

            SOME EXAMPLES OF THOSE WHO DID NOT HEED THE WARNINGS:

         1-2008:  Nineteen-year old Arizona man died after falling into 35’ abandoned mineshaft.

         2-2008:  Twenty-year old man died when he came in contact with a high voltage transformer in a fenced-in area of an active mine in Pennsylvania.

        5-2008:  Three men in their twenties died from lack of oxygen when exploring an abandoned mine in California.

        5-2008:  Eighteen-year old boy drowned in off-limits, privately owned quarry.  Gates were locked and signs warning trespassers were all around.

NEAR MISSES:

        A twenty-three year old Pennsylvania man survived a 500’ fall into an abandoned strip mine.  While trespassing, he fell into a 700’ deep, 3,000’ long, and 1,500’ wide mine; rescuers spent hours on a dangerous rescue.  He faces charges of defiant trespass.

        Two twenty-one year old men escaped serious injury in a car crash in Wisconsin.  No seatbelts were used.  This happened in a rock quarry near an active mine. 

Throughout the year, “Stay Out–Stay Alive” partners visit schools, communities and youth organizations around the country to educate children about the importance of steering clear of abandoned mines.

These are not places to be explored.  I there are warning signs – take heed!
