Asphalt Worker Safety

Asphalt is widely used for paving, road construction, roofing, and other applications. Depending on the product and process, workers may be exposed to hot materials, asphalt fumes, chemical additives, moving equipment, traffic, and fire hazards. Proper training, PPE, and safe work practices are essential.

Know the Material

Asphalt products vary considerably. Some contain solvents, additives, polymers, or other substances that introduce additional hazards. Before beginning work, review the product label and Safety Data Sheet (SDS) to understand:

• Health and physical hazards.
• Safe handling and application procedures.
• Required PPE.
• Exposure controls and ventilation requirements.
• Fire and emergency procedures.
• First-aid measures.

Never assume that all asphalt products present the same hazards.

Fumes and Vapors

Heating and applying asphalt can produce fumes and vapors that may irritate the eyes, nose, throat, and respiratory system. Solvents and other additives may create additional health hazards.

To reduce exposure:

• Avoid standing directly in asphalt fumes or vapors.
• Stay upwind whenever practical.
• Keep your face away from open tanks, kettles, and mixing equipment.
• Use enclosed systems, local exhaust, or other ventilation when available.
• Keep asphalt at the lowest temperature necessary for proper application.
• Follow applicable exposure limits for asphalt fumes and individual chemical ingredients.

Some tanks and enclosed spaces containing asphalt or asphalt products may also present hydrogen sulfide (H₂S) hazards. Never enter or place your head inside tanks, vessels, or other enclosed areas without proper hazard evaluation and required precautions.

Prevent Burns

Hot asphalt can cause severe thermal burns. Wear PPE appropriate for the task, which may include:

• Heat-resistant gloves.
• Long sleeves, long pants, or protective coveralls.
• Safety glasses or chemical splash goggles.
• A face shield when splash hazards exist.
• Appropriate safety footwear.

Avoid direct contact with hot asphalt and never reach over or unnecessarily approach open kettles, tanks, or containers.

If hot asphalt contacts the skin, cool the affected area promptly with water and obtain appropriate medical attention. Do not attempt to pull hardened asphalt from the skin.

Fire and Explosion Prevention

Heated asphalt and some asphalt products containing solvents can present significant fire hazards.

• Keep flames, sparks, smoking, and other ignition sources away from flammable materials and vapors.
• Keep appropriate fire-extinguishing equipment readily available.
• Inspect kettles, tanks, hoses, burners, and fuel systems before use.
• Never perform welding or other hot work on asphalt tanks or containers until they have been properly evaluated, cleaned, and determined safe.
• Never allow water to enter hot asphalt, because rapid steam formation can cause violent splattering or boil-over.

Personal Hygiene

Avoid unnecessary skin contact with asphalt and related products. Wash exposed skin thoroughly and wash your hands before eating, drinking, smoking, or using the restroom.

Never use gasoline, diesel fuel, solvents, or similar products to clean asphalt from your skin.

Remember

Asphalt work can expose employees to burns, fumes, hazardous chemicals, fires, and explosions. Know the product you are using, review the SDS, control fumes and ignition sources, wear appropriate PPE, and handle hot asphalt carefully.
