Handling Poisoning and Chemical Exposure Toolbox Talk

Poisoning and chemical exposure can happen when workers breathe fumes, swallow contaminated material, absorb chemicals through skin, or get splashed in the eyes. Solvents, fuels, cleaners, adhesives, acids, caustics, pesticides, concrete products, gases, and contaminated water can all cause serious injury if the crew does not respond quickly.

This talk focuses on recognizing chemical exposure, stopping the source, using the safety data sheet, flushing skin or eyes, calling for emergency help, and protecting the crew from secondary exposure.

Why This Matters

• Chemicals can burn skin, damage eyes, affect breathing, cause dizziness, or make a worker collapse.
• Some exposures get worse over time, even if symptoms seem minor at first.
• Workers can be exposed while mixing products, cleaning tools, fueling equipment, spraying materials, or entering poorly ventilated areas.
• Using the wrong first aid steps can make the injury worse.
• Fast reporting helps responders identify the chemical and choose the right treatment.

Common Hazards

• Breathing fumes from solvents, fuels, adhesives, coatings, generators, heaters, or equipment exhaust.
• Skin contact with acids, caustics, wet concrete, cleaners, degreasers, fuel, oils, or contaminated water.
• Chemical splashes during pouring, mixing, spraying, pumping, pressure washing, or cleanup.
• Unlabeled containers, damaged labels, missing SDS information, or chemicals stored in drink bottles.
• Poor ventilation in basements, tanks, pits, enclosed rooms, trailers, or confined spaces.
• Workers eating, drinking, smoking, or touching their face with contaminated gloves or hands.
• A worker feeling dizzy, nauseated, confused, short of breath, or irritated after working around fumes that were not obvious at first.

Safety Checklist

Before Work Begins

• Identify chemicals being used today and review labels, SDS information, exposure routes, PPE, and first aid steps.
• Locate eyewash, emergency shower, clean water, first aid kit, spill kit, phone, radio, and emergency contact list.
• Check that containers are labeled, sealed, compatible, and stored away from heat, ignition sources, drains, and traffic areas.
• Confirm workers have the required gloves, goggles, face shield, respirator, protective clothing, and ventilation for the task.
• Make sure workers know who to notify for spills, exposures, symptoms, or missing SDS information.

During Work

• Stop work and move the affected worker away from the exposure only if it can be done safely.
• Call emergency services for breathing trouble, collapse, confusion, chemical burns, eye exposure, swallowed chemicals, or unknown exposure.
• Use the SDS and product label to confirm first aid steps and share the chemical name with responders.
• For skin exposure, remove contaminated clothing and flush the area with clean water as directed by the SDS.
• For eye exposure, flush immediately at an eyewash station and continue while help is called.
• Do not induce vomiting or give food, drink, or medication unless directed by medical professionals or poison control.
• Keep other workers out of the area until the spill, fumes, ventilation issue, or exposure source is controlled.

Crew Talking Points

• What chemicals, fuels, cleaners, coatings, gases, or concrete products are being used today?
• Where are the SDS, eyewash, emergency shower, clean water, spill kit, and first aid supplies?
• What PPE and ventilation are required for the chemical tasks on this job?
• Who should the crew notify if someone has symptoms or a spill occurs?
• What information should be given to emergency responders or poison control?
• Speak up if containers are unlabeled, SDS information is missing, ventilation is poor, or chemical PPE is not available.

Stop Work If

• A worker has breathing trouble, chest tightness, confusion, dizziness, collapse, chemical burns, or eye exposure.
• A chemical is swallowed, injected, splashed in the eyes, or spilled on a large area of skin or clothing.
• The chemical is unknown, unlabeled, mixed incorrectly, or reacting with another product.
• Ventilation is poor and fumes, vapors, gases, or exhaust are building up.
• Eyewash, emergency shower, clean water, SDS information, PPE, or spill control supplies are missing or blocked.

Final Reminder

Chemical exposure can turn serious fast. Stop the source, flush skin or eyes when needed, use the SDS, call for help, and keep others out of the exposure area.
