4.9.1 - Weather Considerations

Cold

Extended exposure to windy, cold weather can lead to frostbite, hypothermia, and possibly death. The cold

stress equation is as follows:

LOW TEMPERATURE + WIND SPEED + WETNESS = INJURY & ILLNESS

The Occupational Safety and Health Administration (OSHA) and the Mine Safety and Health

Administration (MSHA) offer the following steps for recognizing, evaluating, and controlling cold stress:

• Recognize the environmental and workplace conditions that lead to potential cold-induced illnesses and

injuries.

• Learn the signs and symptoms of cold-induced illnesses/injuries and what to do to help the worker.

• Drink warm, sweet beverages (sugar water, sports-type drinks). Avoid drinks with caffeine (coffee, tea,

or hot chocolate) or alcohol, which cause dehydration. Eat warm, high-calorie foods like hot pasta

dishes.

• Dress appropriately, layer clothing to adjust to changing environmental temperatures. Wear a hat and

gloves, in addition to underwear that will keep water away from the skin (i.e., polypropylene).

• Take frequent breaks in warm, dry shelters to allow the body to warm up.

• Perform work during the warmest part of the day.

• Avoid exhaustion or fatigue because energy is needed to keep muscles warm.

• Workers are at greater risk when they have predisposing health conditions such as cardiovascular

disease, diabetes, and hypertension, they take certain medications (check with a doctor, nurse, or

pharmacy to see if any medications being taken have adverse affects while working in cold

environments), or they are in poor physical condition, have a poor diet, or are older.

• During freezing weather, do not touch any metal parts of the drill rig with exposed flesh. Freezing of

moist skin to metal can occur almost instantaneously.

• All air and water lines and pumps should be drained when not in use if freezing weather is expected. If

appropriate, the rig should be winterized at the end of each day.

• Take breaks as necessary to warm up.

Heat

• During hot weather take frequent breaks and drink plenty of fluids.

• Dress appropriately for the conditions expected.

• Maintain a supply of drinking water.

• Take breaks as needed to cool off.
