Weather Hazards Guide for Scrap Metal Facility Employees

Part 1: Hot Weather Hazards

Working in a scrap metal facility during summer months presents serious heat-related risks. Metal surfaces can reach extreme temperatures, radiating additional heat while you’re already working in hot conditions. Understanding these hazards and staying properly hydrated can prevent serious illness or injury.

Heat Exhaustion

What It Is: Heat exhaustion occurs when your body loses excessive water and salt through sweating. It’s a warning sign that your body is struggling to cool itself.

How to Spot It:

• Heavy sweating with cool, pale, clammy skin
• Fast, weak pulse
• Nausea or vomiting
• Muscle cramps
• Tiredness or weakness
• Dizziness or fainting
• Headache

First Aid:

• Move the person to a cooler location (air-conditioned building or shaded area)
• Have them lie down and loosen clothing
• Apply cool, wet cloths to the body or have them take a cool bath
• Give small sips of water frequently (don’t chug large amounts)
• If they vomit, stop giving water and seek medical attention
• If symptoms worsen or last longer than one hour, call 911

Hydration Focus: Heat exhaustion often results from inadequate fluid replacement. Drink water every 15-20 minutes during hot weather work, even if you don’t feel thirsty. Sports drinks can help replace lost electrolytes, but water should be your primary source. Aim for at least one cup (8 oz) every 15-20 minutes during active work.

Heat Stroke

What It Is: Heat stroke is a life-threatening emergency where the body’s temperature regulation system fails. This is the most serious heat-related illness.

How to Spot It:

• Body temperature of 103°F or higher
• Hot, red, dry, or damp skin (may not be sweating)
• Fast, strong pulse
• Headache, dizziness, or confusion
• Nausea
• Loss of consciousness

First Aid:

• Call 911 immediately—this is a medical emergency
• Move the person to a cooler place
• Do NOT give them anything to drink
• Lower body temperature with cool cloths or a cool bath
• Focus on cooling the head, neck, armpits, and groin

Hydration Focus: Heat stroke often occurs when heat exhaustion isn’t recognized and treated early. Prevention through consistent hydration throughout the day is critical. Start your shift well-hydrated, and never wait until you feel thirsty to drink water.

Heat Cramps

What It Is: Painful muscle spasms, usually in the legs, arms, or abdomen, caused by loss of salt and water through sweating.

How to Spot It:

• Sudden, painful muscle spasms during or after work
• Usually affects muscles being used the most
• Heavy sweating during intense activity

First Aid:

• Stop all activity and sit in a cool place
• Drink water or a sports drink
• Wait for cramps to go away before returning to work
• Seek medical help if cramps last more than one hour, if you have heart problems, or are on a low-sodium diet

Hydration Focus: Heat cramps are a direct sign of electrolyte imbalance from sweating. In addition to water, consume electrolyte-rich drinks or foods during breaks. Consider bringing salted snacks or electrolyte tablets to add to your water on particularly hot days.

Heat Rash

What It Is: Skin irritation from excessive sweating, appearing as red clusters of small blisters or pimples.

How to Spot It:

• Red clusters of small blisters or pimples on the skin
• Usually appears on neck, chest, groin, elbow creases, or under breasts
• Itching or prickling sensation

First Aid:

• Keep the affected area dry
• Use powder to soothe the area
• Avoid ointments or creams that can block pores further
• Take breaks in cool, air-conditioned areas

Hydration Focus: While heat rash itself isn’t directly caused by dehydration, staying well-hydrated helps your body regulate temperature more effectively, reducing excessive sweating that leads to rash. Proper hydration also supports overall skin health and healing.

Part 2: Cold Weather Hazards

Winter work in scrap metal facilities brings unique dangers. Cold metal conducts heat away from your body rapidly, and physical exertion in cold weather can mask dehydration symptoms. Many workers don’t realize they need to maintain hydration in cold weather just as much as in hot weather.

Hypothermia

What It Is: A dangerous drop in body temperature (below 95°F) that occurs when your body loses heat faster than it can produce it. Handling frozen metal or working in cold conditions accelerates heat loss.

How to Spot It:

Mild Hypothermia (90-95°F):

• Shivering
• Cold, pale skin
• Fatigue or drowsiness
• Confusion or difficulty concentrating
• Slurred speech
• Clumsiness or lack of coordination

Severe Hypothermia (below 90°F):

• Shivering stops
• Slow, shallow breathing
• Weak pulse
• Confusion or memory loss
• Loss of consciousness
• Bright red, cold skin (in infants)

First Aid:

• Call 911 if the person shows signs of severe hypothermia
• Move them to a warm, dry location
• Remove any wet clothing
• Warm the person gradually with blankets, starting with the chest and core
• Give warm (not hot) beverages if they’re alert and can swallow—avoid alcohol or caffeine
• Do NOT use direct heat (heating pads, hot water) or rub their limbs
• Monitor breathing and be prepared to perform CPR

Hydration Focus: Cold weather suppresses thirst, but you still lose significant fluids through breathing (visible as vapor in cold air) and sweating under layers of clothing. Dehydration makes you more susceptible to hypothermia because blood volume decreases, reducing circulation to extremities. Drink warm water or non-caffeinated beverages regularly throughout your shift, aiming for at least 4-6 ounces every 30 minutes. Avoid excessive caffeine and alcohol, as they promote dehydration and affect temperature regulation.

Frostbite

What It Is: Freezing of skin and underlying tissues, most commonly affecting fingers, toes, nose, ears, cheeks, and chin. Direct contact with frozen metal can cause frostbite in seconds.

How to Spot It:

Early Stage (Frostnip):

• Pale or red skin
• Numbness or tingling
• Cold to the touch

Superficial Frostbite:

• Skin appears white, waxy, or grayish-yellow
• Skin feels firm or hard but tissue beneath feels normal
• Burning or stinging sensation
• Blisters may form after rewarming

Severe (Deep) Frostbite:

• Skin is white or bluish-gray
• Skin and tissue underneath feel hard and cold
• Complete numbness
• Large blisters form after rewarming
• Tissue may turn black (indicating tissue death)

First Aid:

• Get to a warm location immediately
• Do NOT walk on frostbitten feet or toes
• Immerse affected area in warm (not hot) water, 98-105°F, for 20-30 minutes
• Do NOT rub or massage frozen tissue
• Do NOT use direct heat sources (heating pads, fireplaces, radiators)
• Loosely bandage the area with sterile, dry dressings (place between frostbitten fingers/toes)
• Give warm, non-alcoholic, non-caffeinated beverages
• Seek medical attention, especially for severe frostbite

Hydration Focus: Dehydration thickens your blood, reducing circulation to extremities and increasing frostbite risk. Proper hydration maintains blood volume and flow to fingers, toes, and other vulnerable areas. Drink warm fluids regularly throughout the day, even if you’re not thirsty. Avoid alcohol, which dilates blood vessels and accelerates heat loss while also dehydrating you.

Cold Stress and Trench Foot

What It Is: Trench foot (immersion foot) occurs when feet are wet and cold for extended periods, even in temperatures above freezing. This can happen from sweating inside boots during winter work.

How to Spot It:

• Tingling, itching, or burning sensation
• Reddened skin
• Swelling
• Numbness
• Blisters in later stages
• In severe cases, skin may turn gray or blue, and tissue may die

First Aid:

• Remove wet footwear and socks
• Dry the feet thoroughly
• Warm feet gradually (avoid direct heat)
• Do NOT walk on affected feet
• Keep feet elevated
• Seek medical attention for severe cases

Hydration Focus: Adequate hydration helps regulate body temperature and sweating. When properly hydrated, your body manages moisture more effectively, potentially reducing excessive sweating inside boots. Additionally, staying hydrated supports healthy circulation to prevent tissue damage.

Dehydration in Cold Weather

What It Is: Many workers don’t realize that cold weather causes significant fluid loss. You lose water through increased respiration (breathing out vapor in cold air), sweating under insulated clothing, and reduced thirst sensation.

How to Spot It:

• Dry mouth and tongue
• Dark yellow urine or infrequent urination
• Fatigue or dizziness
• Confusion or irritability
• Headache
• Increased heart rate

First Aid:

• Drink warm fluids immediately
• Move to a warmer environment if possible
• Continue drinking small amounts frequently
• Seek medical attention if symptoms are severe or don’t improve

Hydration Focus: Cold weather dehydration is insidious because you don’t feel thirsty. Make a schedule: drink 4-6 ounces of warm fluids every 30 minutes. Warm water, herbal tea, or warm broth are excellent choices. Monitor urine color—it should be pale yellow. If it’s dark, you’re already dehydrated. Start each shift well-hydrated and maintain it throughout the day. Remember that caffeine is a diuretic, so limit coffee and energy drinks.
