According to the National Oceanic and Atmospheric Administration, the summer of 2010 was the fourth warmest summer on United States records at the time. Most oil spill cleanup workers reported for long shifts and worked almost entirely outside, often in temperatures surpassing 95 degrees. Many workers reported that fresh water was not always readily available, so many of the workers suffered from heat exhaustion and heat stroke. These individuals were treated at work site tents, and often sent right back to work.
Some of the symptoms of heat related conditions include dizziness, lightheadedness, nose bleeds, blurred vision, headaches, fainting, and vomiting. These conditions are considered acute specified physical conditions under the settlement. An enhancer is available to any individual who was actually transported to the hospital after one of these heat-related episodes.
