Spray Foam Health and Safety Considerations

Safety Factors to Consider When Applying Two-Component SPF

The material is called two-component foam because the chemicals used to make the foam are stored in two separate containers. When sprayed, the chemicals are mixed together and a spray gun delivers the resulting foam.

Low-pressure foam is usually delivered at less than 250psi, whereas high-pressure foam is usually delivered at 1000psi or more.

Both high- and low-pressure, two-component spray foam are applied by professional contractors who are trained to use and apply SPF with the required safety equipment (protective gear, full eye protection, respirators, and gloves). Contractors should follow the ventilation recommendations by the product manufacturer to avoid overexposure through inhalation, and instruct those without protective gear (homeowners or building occupants) to stay away from the work area during exposure times and to not return until instructed by the professional contractor.

Safety Factors to Consider When Applying Insulating Foam Sealant

  • Follow instructions on the product label: Read and follow all instructions on the product label carefully.
  • Provide ventilation: Provide plenty of ventilation to avoid breathing vapors and mist until the foam has hardened.
  • Wear appropriate protective gear: It is important that you wear protective gear, often referred to as “personal protective equipment” (PPE), when applying insulating foam sealant.
  • Wear the clothing and eye protection recommended by the product manufacturer on the label. This can be safety glasses or goggles, full-coverage clothing, e.g., long sleeves, and gloves. Avoid getting foam on your skin or in your hair. (The foam is highly adhesive and very difficult to remove).
