Chemical Exposure Symptoms Toolbox Talk

Chemical exposure can happen from breathing fumes, getting liquid on skin, splashing material in the eyes, swallowing residue, or carrying contamination on gloves and clothing. Symptoms may show up right away or build slowly during the shift.

This talk focuses on recognizing chemical exposure symptoms early, reporting them right away, using first aid and emergency response steps, and stopping work when workers may be exposed.

Why This Matters

• Early symptoms can be easy to ignore, such as headache, dizziness, coughing, burning skin, or eye irritation.
• Some chemicals can injure workers before they smell, taste, or see the hazard.
• Delayed reporting can make burns, breathing problems, poisoning, or allergic reactions worse.
• Contaminated gloves, sleeves, boots, tools, and clothing can spread chemicals to clean areas.
• Quick action helps protect the exposed worker and prevents other crew members from being exposed.

Common Hazards

• Breathing fumes, vapors, mist, dust, exhaust, or smoke during mixing, spraying, coating, cleaning, or cutting.
• Chemicals contacting skin through soaked gloves, torn sleeves, open cuffs, wet boots, or contaminated clothing.
• Splashing chemicals into the eyes or face while pouring, pumping, transferring, pressure washing, or opening containers.
• Eating, drinking, smoking, or touching the face with contaminated hands or gloves.
• Ignoring symptoms because the task is almost done or other workers do not feel sick yet.
• A worker having symptoms after leaving the exposure area because residue stayed on clothing, boots, tools, or PPE.

Safety Checklist

Before Work Begins

• Review the product label, safety data sheet, exposure controls, first aid steps, and emergency contact procedure.
• Know the symptoms listed for the chemical, including inhalation, skin contact, eye contact, and ingestion exposure.
• Confirm required PPE is available, fits correctly, and matches the chemical hazard.
• Locate eyewash, wash stations, clean water, spill supplies, ventilation, and exit routes before handling chemicals.
• Set up work so fumes, mist, dust, and splash are controlled before workers enter the area.
• Keep clean areas separate from chemical work areas, contaminated PPE, and waste containers.

During Work

• Watch for headache, dizziness, nausea, coughing, chest tightness, trouble breathing, confusion, weakness, or unusual fatigue.
• Watch for burning, itching, redness, rash, numbness, blisters, or wet clothing that may indicate skin exposure.
• Watch for eye watering, burning, blurred vision, pain, redness, or trouble keeping eyes open.
• Leave the exposure area before adjusting respirators, removing goggles, drinking water, or checking irritated skin.
• Report symptoms immediately to the foreman, safety lead, or supervisor.
• Remove contaminated PPE and clothing carefully so residue does not spread to skin, vehicles, tools, or clean areas.

Crew Talking Points

• What chemicals are we using today, and what symptoms should we watch for?
• Where are the eyewash, wash station, safety data sheet, spill kit, and emergency contacts?
• What PPE, ventilation, or work controls are required before exposure can start?
• How will workers report symptoms or chemical contact during the task?
• Where will contaminated gloves, clothing, tools, and waste be handled after use?
• Speak up right away if you feel sick, smell strong fumes, get chemical on your skin, splash your eyes, or notice symptoms in a coworker.

Stop Work If

• A worker has dizziness, nausea, confusion, trouble breathing, chest tightness, burns, rash, eye pain, or other exposure symptoms.
• Chemicals contact skin, eyes, regular clothing, or the inside of PPE.
• Strong fumes, mist, dust, vapors, or odors build up in the work area.
• Required ventilation, respirators, goggles, gloves, protective clothing, eyewash, or wash stations are not available.
• The chemical is unknown, unlabeled, mixed incorrectly, reacting, leaking, or spilled.
• The crew does not understand the safety data sheet, first aid steps, or emergency response plan.

Final Reminder

Chemical exposure symptoms are warning signs. Do not tough it out. Leave the area, report symptoms, wash contamination off, and get help before the exposure gets worse.
