Substituting Safer Materials Toolbox Talk

Many health hazards start with the material chosen for the job. A coating, adhesive, cleaner, solvent, dust-producing product, or treated material may create vapors, skin hazards, fire risks, or breathing exposures. In some cases, a safer option can reduce the hazard before the work even begins.

This talk focuses on substituting safer materials when possible. The goal is to look at the task, review the product hazards, and choose materials or methods that reduce exposure without creating a new problem.

Why This Matters

• Substitution controls the hazard before workers are exposed.
• Using a less hazardous product can reduce breathing problems, skin irritation, chemical burns, fire risk, and long-term health effects.
• Safer materials can reduce the need for heavy ventilation, respirators, special cleanup, or restricted work areas.
• Some products look similar but have very different hazards, such as solvent-based versus water-based coatings.
• A safer material still needs to be reviewed, handled, stored, and used correctly.

Common Hazards

• Using high-solvent adhesives, primers, paints, or sealants when a lower-VOC or water-based option is available and approved.
• Choosing dry cutting, grinding, or mixing methods when pre-cut materials, wet methods, or dust-reducing products could be used.
• Using strong chemical cleaners when mild detergents, mechanical cleaning, or less hazardous products would work.
• Selecting materials that release dust, fumes, vapors, or fibers during installation, cutting, sanding, demolition, or cleanup.
• Replacing one product with another without checking the safety data sheet, manufacturer instructions, compatibility, or performance requirements.
• Using flammable products near hot work, heaters, electrical equipment, or poor ventilation.
• Assuming “green,” “low odor,” or “non-toxic” means the product has no health hazards.
• A safer substitute requiring a longer cure time, different PPE, or different ventilation than the crew expected.

Safety Checklist

Before Work Begins

• Review the task and identify materials that may create dust, fumes, vapors, gases, fibers, skin hazards, or fire hazards.
• Check the safety data sheet and label for each product being considered.
• Ask whether a lower-hazard product or method is approved for the job specifications.
• Compare hazards such as VOC content, flammability, skin contact risk, respiratory hazard, odor, cleanup needs, and disposal requirements.
• Confirm the substitute is compatible with the surface, weather, temperature, equipment, and manufacturer requirements.
• Make sure the crew has the correct PPE, ventilation, storage, and cleanup supplies for the material selected.
• Communicate product changes to the crew and other trades that may be affected.

During Work

• Use only the approved material for the task. Do not swap products in the field without review.
• Follow the label and safety data sheet for mixing, application, ventilation, PPE, storage, and cleanup.
• Keep containers closed when not in use to reduce vapors, spills, and contamination.
• Watch for unexpected odors, skin irritation, coughing, dizziness, headaches, or other symptoms.
• Keep ignition sources away from flammable or combustible materials, even if the substitute seems safer.
• Do not mix products unless the manufacturer instructions clearly allow it.
• Control dust at the source when using substituted materials that still require cutting, sanding, drilling, or grinding.
• Stop and review the product if it behaves differently than expected, such as strong fumes, poor curing, overheating, or unusual residue.

Crew Talking Points

• What materials today could create health hazards?
• Is there a safer product or method approved for this task?
• What does the safety data sheet say about ventilation, PPE, skin contact, fire risk, and cleanup?
• Could the substitute create a different hazard, such as longer cure time, slip risk, moisture issues, or flammability?
• Who needs to know about the material change before work starts?
• How will we confirm workers are using the correct product and not an old container or leftover material?
• Ask questions now if the substitute, instructions, PPE, or exposure controls are not clear.

Stop Work If

• A product is being used without a label, safety data sheet, approval, or clear instructions.
• The substitute has not been checked for compatibility, performance, ventilation, PPE, or fire hazards.
• Workers experience headaches, dizziness, coughing, burning eyes, skin irritation, nausea, or trouble breathing.
• A material gives off stronger fumes, more dust, or more heat than expected.
• Products are being mixed, thinned, heated, or sprayed in a way not allowed by the manufacturer.
• Other trades, occupants, or public areas may be exposed because the material change was not communicated.

Final Reminder

The safest exposure is the one you prevent before the job starts. Choose safer materials when they are approved, read the SDS, and make sure the substitute does not bring a new hazard with it.
