Chemical Exposure: When Should You Go to the ER?

Chemical exposure can happen in seconds. A splash from a household cleaner, fumes from mixed cleaning products, a workplace accident, or accidental ingestion can quickly turn into a medical emergency.

While some minor exposures may cause temporary irritation, others can damage the skin, eyes, lungs, digestive system, or other parts of the body. In some cases, serious symptoms may not appear immediately, making it important to know when professional medical evaluation is necessary.

What Is Chemical Exposure?

Chemical exposure occurs when a potentially harmful substance enters or comes into contact with the body. Exposure can occur through the skin, eyes, lungs, or digestive system.

The severity of an exposure can depend on several factors, including the chemical involved, its concentration, the amount of exposure, how long the person was exposed, and the route through which the chemical entered the body.

According to the Centers for Disease Control and Prevention (CDC), an important general approach during a chemical emergency is to get away from the source, get the chemical off the body when appropriate, and get help.

Common Types of Chemical Exposure at Home and Work

Chemical exposures can occur at home, at work, outdoors, or during recreational activities. Some of the most common situations include:

Household cleaning products: Bleach, ammonia, drain cleaners, oven cleaners, toilet bowl cleaners, detergents, and disinfectants can irritate or burn the skin, eyes, lungs, and digestive tract. Mixing certain household chemicals can also create dangerous gases.

Workplace and industrial chemicals: Employees in construction, manufacturing, agriculture, automotive work, healthcare, maintenance, and other industries may encounter solvents, acids, alkalis, fuels, gases, pesticides, and other hazardous substances.

Chemical fumes and gases: Inhaling chlorine gas, cleaning-product fumes, solvents, pesticides, or other chemical vapors may irritate the nose, throat, and lungs. Some exposures can cause coughing, chest tightness, wheezing, dizziness, or difficulty breathing.

Chemical burns: Strong acids, bases, drain cleaners, cement products, industrial chemicals, and other corrosive substances can cause burns when they come into contact with the skin or eyes. Chemical burns may continue damaging tissue until the substance has been adequately removed.

Eye exposure: Chemicals splashed into the eyes can cause burning, redness, excessive tearing, blurred vision, swelling, or more serious eye injuries. Immediate flushing is often important following chemical eye exposure.

Accidental ingestion: Children may accidentally swallow household chemicals, while adults may unintentionally ingest substances that have been improperly stored or transferred into food or drink containers. Chemical ingestion can potentially injure the mouth, throat, esophagus, stomach, and other organs.

Pesticides and lawn chemicals: Insecticides, herbicides, fertilizers, and other lawn or agricultural chemicals may cause symptoms following inhalation, ingestion, or significant skin exposure.

Chemical Exposure Symptoms That Require Emergency Care

The effects of chemical exposure can vary considerably depending on the substance. Some symptoms appear almost immediately, while others can develop more slowly.

Seek emergency medical attention for concerning symptoms such as:

• Difficulty breathing, shortness of breath, wheezing, or severe coughing
• Chest pain or tightness
• Severe or worsening chemical burns
• Significant eye pain or changes in vision
• Persistent vomiting
• Severe abdominal pain
• Confusion, extreme drowsiness, or unusual behavior
• Fainting or loss of consciousness
• Seizures
• Significant swelling of the face, lips, tongue, or throat
• Severe dizziness or weakness
• Extensive blistering or skin damage
• Suspected ingestion of a dangerous or corrosive chemical

If someone collapses, experiences a seizure, has difficulty breathing, or cannot be awakened following a suspected poisoning or chemical exposure, call 911 immediately.

Even if symptoms initially seem mild, you may still need medical evaluation depending on the substance and amount of exposure. Some chemical-related injuries and poisonings do not cause obvious symptoms immediately.

Chemical Exposure First Aid: What to Do Before Going to the ER

What you do immediately after chemical exposure can be important. However, first-aid recommendations can vary depending on the chemical involved. When possible, follow the product’s safety instructions and contact Poison Control at 1-800-222-1222 for guidance specific to the substance.

1. Move Away From the Chemical

If you have inhaled fumes or vapors indoors, move away from the source and get to fresh air as quickly as you safely can. Avoid entering or remaining in an area with dangerous fumes.

During a larger chemical release, follow instructions from emergency officials about whether you should evacuate or shelter in place.

2. Remove Contaminated Clothing

If a chemical has gotten onto your clothing, removing contaminated clothing can help prevent continued exposure. Avoid unnecessarily touching contaminated areas of the clothing.

The CDC recommends getting chemicals off the body as quickly as possible following many types of chemical emergencies.

3. Rinse Chemicals From the Skin or Eyes When Appropriate

For many chemical exposures involving the skin or eyes, immediate flushing with water may be recommended. Poison Control advises rinsing chemical exposures to the eyes with lukewarm water for 15 to 20 minutes and flooding exposed skin with water.

However, certain chemicals require special handling. If you know what substance caused the exposure, follow the product’s emergency instructions and guidance from Poison Control.

4. Do Not Try to Neutralize the Chemical Yourself

Do not apply another chemical in an attempt to “cancel out” or neutralize the substance. Combining chemicals can potentially cause additional reactions and injuries. MedlinePlus advises against trying to neutralize a chemical without instructions from Poison Control or a healthcare professional.

Avoid applying ointments, creams, oils, or household remedies to chemical burns unless instructed by a medical professional.

5. Do Not Automatically Induce Vomiting If a Chemical Is Swallowed

If a chemical has been swallowed, do not automatically make the person vomit. Vomiting can cause certain substances to come back into contact with the esophagus and mouth, potentially causing additional injury.

Contact Poison Control for instructions based on the specific substance involved.

6. Bring Information About the Chemical

If it is safe to do so, bring the product container, label, Safety Data Sheet, or a photo of the label with you to the emergency room. Knowing exactly what substance was involved can help the medical team determine the appropriate evaluation and treatment.

Do not bring a leaking, contaminated, or unsafe container into your vehicle or the ER.

Chemical Burn and Chemical Exposure Treatment at The Emergency Center

When you arrive at The Emergency Center, our emergency medical team can evaluate the type of exposure, your symptoms, and the potential effects the chemical may have had on your body.

Depending on the circumstances, emergency evaluation and treatment may include:

• Monitoring vital signs and oxygen levels
• Evaluating the airway and breathing

• Examination and treatment of chemical burns
• Eye evaluation and irrigation
• Blood or urine testing when indicated
• IV fluids
• Medications to manage pain, nausea, breathing problems, or other symptoms
• Diagnostic imaging when necessary
• Continued monitoring for complications

Treatment varies significantly depending on the substance and route of exposure. For serious poisonings and corrosive ingestions, emergency care can involve airway support, laboratory testing, imaging, IV fluids, medications, and other interventions based on the patient’s condition.
