First Aid Treatment & Chemical Exposure Control

Key Takeaways

• First aid is immediate care given to an injured or ill person before professional medical help arrives.
• Common first aid treatments include those for cuts, burns, choking, cardiac arrest, bleeding, and frostbite.
• Chemical exposure in the workplace can occur through inhalation, skin contact, ingestion, or injection.
• The hierarchy of controls (elimination, substitution, engineering controls, administrative controls, and PPE) is important in preventing chemical exposure.

What is First Aid?

According to the Occupational Safety and Health Administration (OSHA), first aid involves providing immediate medical care to an injured or ill person at the scene of an incident, before professional help arrives. It typically includes short-term, one-time treatments that don't require extensive training or advanced equipment.

First aid treatment may cover actions like cleaning and bandaging minor wounds, treating small burns, removing foreign objects from eyes, applying cold compresses, or helping someone drink fluids to combat heat stress.

How to Build a First Aid Kit

First aid treatment can make a significant difference in preventing minor injuries from worsening. Having a well-stocked first aid kit on hand allows for quick response in emergencies.

A basic first aid kit should contain:

The ABCs of First Aid

The ABCs of first aid serve as a primary assessment and treatment guideline during emergencies:

• A - Airway: Check if the airway is open and clear
• B - Breathing: Verify if the person is breathing normally
• C - Circulation: Look for a pulse and control any severe bleeding

Common First Aid Treatments

Cuts, Scrapes, and Scratches

Cuts, scrapes, and scratches are common injuries that break the skin. They can result from accidents with sharp objects, falls, or abrasions against rough surfaces. These injuries can range from minor to severe and may be complicated by debris or chemical hazards.

First Aid Treatment for Cuts, Scrapes, and Scratches

1. Clean the wound with soap and water
2. Apply an antibiotic ointment
3. Cover with a sterile bandage
4. For deeper cuts, apply direct pressure to stop bleeding before cleaning and bandaging

Burns

Burns are tissue damage caused by heat, chemicals, electricity, or radiation. They can occur from contact with hot surfaces, scalding liquids, or exposure to chemical hazards. Burns are classified by severity into first, second, and third-degree.

First Aid Treatment for Burns

1. Cool the burn under running water for at least 10 minutes
2. Remove any jewelry or tight items from the burned area
3. Apply a clean, dry dressing
4. For severe burns, call emergency services immediately
5. Keep the victim warm and the burned area elevated if possible

Choking

Choking occurs when an object blocks the airway, preventing normal breathing. It can happen while eating, or when small objects are accidentally inhaled. Choking can quickly become life-threatening if not addressed promptly.

First Aid Treatment for Choking

1. Encourage the person to cough
2. If coughing is ineffective, perform back blows: give 5 sharp blows between the shoulder blades
3. If back blows fail, perform abdominal thrusts (Heimlich maneuver):
1. Stand behind the person
2. Place one hand on their abdomen just above the navel
3. Make a fist with the other hand
4. Give quick, upward thrusts until the object is expelled
4. If the person becomes unconscious, begin CPR

Cardiac Arrest

Cardiac arrest is the sudden loss of heart function. It can be caused by heart attack, electric shock, or other heart conditions. Immediate action is critical for survival.

First Aid Treatment for Cardiac Arrest

1. Call emergency services immediately
2. Begin CPR:
1. Place hands on the center of the chest
2. Perform chest compressions at a rate of 100-120 per minute
3. If trained, alternate 30 compressions with 2 rescue breaths
3. Use an AED if available, following its instructions
4. Continue CPR until emergency services arrive

Bleeding

Bleeding can range from minor cuts to severe, life-threatening hemorrhages. It can result from injuries, medical conditions, or complications from chemical hazards. The severity depends on the location and amount of blood loss.

First Aid Treatment for Bleeding

1. Apply direct pressure to the wound with a clean cloth or sterile gauze
2. Elevate the injured area above the heart if possible
3. Maintain pressure until bleeding stops
4. Apply a bandage once bleeding is controlled
5. For severe bleeding, continue pressure and seek emergency medical help immediately

Frostbite

Frostbite is tissue damage caused by exposure to freezing temperatures. It most commonly affects extremities like fingers, toes, nose, and ears. Frostbite can occur quickly in severe cold, especially with wind chill.

First Aid Treatment for Frostbite

1. Move the person to a warm area
2. Remove wet or tight clothing
3. Gently warm the affected area with body heat or warm (not hot) water
4. Do not rub the frostbitten area
5. Cover the area with dry, sterile dressings
6. Seek medical attention, especially for severe cases

Chemical Exposure in the Workplace

In addition to physical injuries, workplace chemical exposure poses significant risks. Recognizing these chemical hazards is important for effective first aid treatment and prevention.

Chemical exposure can occur through various pathways in the workplace. Each route presents unique risks and requires specific chemical safety measures:

• Inhalation: Breathing in harmful gases, vapors, dust, or mist
• Ingestion: Accidental swallowing of hazardous substances
• Skin Absorption: Chemicals penetrating the skin or entering through cuts
• Eye Contact: Splashes or airborne particles contacting the eyes

Here are common examples of chemical hazards and their primary exposure routes:

Why Must You Be Cautious of Chemical Exposure at Work?

Chemical exposure in the workplace can lead to a range of health issues, from minor irritations to severe, life-threatening conditions. Below are the health effects of chemical exposure:

• Acute Effects: These may include irritation of the eyes, nose, and throat, leading to discomfort and potential difficulty breathing. Headaches, dizziness, nausea, and vomiting are common symptoms that can occur shortly after exposure.
• Chronic Effects: Respiratory diseases, such as asthma or chronic bronchitis, may develop over time. Prolonged exposure to certain chemicals can cause liver and kidney damage, potentially leading to organ failure. Neurological disorders, including memory loss or cognitive impairment, can also result from extended chemical exposure.
• Reproductive Effects: Exposure may lead to fertility issues in both men and women, making it difficult to conceive. Pregnant women exposed to certain chemicals risk potential harm to their unborn children, including birth defects or developmental issues.
• Sensitization: Repeated chemical exposure can cause the body to develop allergies or heightened sensitivity. This process, known as sensitization, can result in increasingly severe reactions to even small amounts of the chemical.
• Systemic Effects: Some chemicals can cause widespread damage throughout the body, affecting multiple organ systems. Blood disorders, such as anemia or leukemia, may develop due to chemical exposure affecting bone marrow function. The interconnected nature of systemic effects often means that treating one symptom may not address the underlying chemical-induced damage.

Chemical Exposure Control

After exploring the risks of workplace chemical hazards, it's important to discuss how to control these risks. Effective control measures not only protect workers from chemical exposure but also improve overall workplace safety and productivity.

Hierarchy of Controls

The hierarchy of controls OSHA recommends is a system for minimizing or eliminating exposure to hazards. This approach prioritizes control strategies from most to least effective:

• Elimination: Physically remove the hazard
• Substitution: Replace the hazard with a safer alternative
• Engineering Controls: Isolate people from the hazard
• Administrative Controls: Change how people work
• Personal Protective Equipment (PPE): Protect workers with personal equipment

Engineering Out Hazards

While engineering controls are highly effective, accidental chemical exposure can still occur. In such cases, quick action and proper first aid are essential. Always have an emergency response plan and first aid supplies readily available.

Real-life scenarios and responses:

Acid splash: A worker accidentally splashes hydrochloric acid on their arm.

• Response: Immediately flush the affected area with cool running water for at least 15 minutes. Remove any contaminated clothing while flushing. Seek medical attention.

Solvent inhalation: An employee is overcome by fumes while cleaning equipment in a poorly ventilated area.

• Response: Remove the worker to fresh air immediately. If breathing is difficult, administer oxygen if available. If breathing has stopped, begin CPR. Call emergency services.

Eye exposure: I once witnessed a coworker get a chemical splash in their eye during a routine transfer process.

• Response: We immediately guided them to the nearby eyewash station and helped flush their eye with water for 15 minutes, holding the eyelid open to ensure thorough irrigation. While doing this, another colleague called for medical assistance. The quick access to the eyewash station and our team's prompt response were crucial in minimizing potential damage.

In all cases, refer to the Safety Data Sheet (SDS) for specific first aid instructions related to the chemical involved. Train all employees on emergency procedures and the locations of safety equipment to ensure rapid response to chemical exposure incidents.

Unsafe Practices

Recognizing common workplace hazards and unsafe practices related to chemical exposure is crucial for maintaining a safe work environment:

• Inadequate engineering controls: Lack of proper equipment shielding or biological safety cabinets
• Poor labeling: Illegible or missing labels on chemical containers
• Improper storage: Storing incompatible chemicals together or flammables near ignition sources
• PPE issues: Unavailable, unused, or improperly fitted protective equipment
• Insufficient ventilation: Poorly maintained or improperly positioned local exhaust systems

First Aid for Chemical Exposure

Despite our best efforts to control chemical hazards, accidents can still occur. To determine the right first aid treatment for workplace chemicals, start by identifying the specific substance involved. Each chemical may require unique handling and treatment methods based on its properties and potential health effects. This is where Safety Data Sheets (SDS) become important in chemical safety.

Importance of Safety Data Sheets (SDS)

Safety Data Sheets (SDS) are crucial documents for understanding the necessary steps to take when dealing with chemical exposure. Each SDS includes a section specifically dedicated to first-aid measures, which outlines the required treatment for exposure and the symptoms that may occur immediately or later.

Key Points on Chemical Exposure Treatment from SDS:

First-Aid Measures (Section 4)

• Inhalation: Move the person to fresh air immediately. If breathing is difficult, trained personnel should provide artificial respiration. Ensure the affected person is in a comfortable position and kept warm until professional medical help arrives.
• Skin Contact: Remove contaminated clothing and rinse the skin thoroughly with water for several minutes. Continue washing with water to ensure all traces of the chemical are removed. Seek medical advice if irritation persists.
