Fire Retardants in Theatre: Are They Toxic?
Fire retardants are essential in theatre production, ensuring that stage curtains, set pieces, and props meet fire safety regulations such as NFPA 701. While these treatments are effective in preventing fire spread, concerns about their toxicity remain. Are fire retardants safe to use, or do they pose health risks?
The answer depends on the chemical composition of the fire retardant in question. Some traditional fire-retardant treatments contained bromine, chlorine, or phosphorus-based compounds, which could pose inhalation or skin contact risks. However, modern flame retardants, such as Rosco Flamex and Turning Star Fire Retardants, are formulated to be safer and compliant with environmental and health standards.
1. Understanding Fire Retardant Safety
Fire retardants generally fall into two categories:
- Inherently Flame-Resistant (IFR) Materials – These fabrics are designed to be permanently fire-resistant without additional chemical treatment.
- Flame Retardant (FR) Treated Materials – These require fire retardant chemicals to achieve compliance with fire codes.
For FR-treated materials, the key safety concern is the chemical composition of the treatment used. Certain older or industrial fire retardants have been linked to respiratory irritation, skin sensitivity, and potential environmental hazards. However, modern formulations aim to minimize these risks while maintaining their fire-resistant properties.
2. Examining Rosco Flamex Fire Retardants
Rosco Flamex is a well-known brand in the theatre industry, offering fire retardant solutions designed to be non-toxic and safe for performers and stagehands when used correctly.
Key Safety Features of Rosco Flamex:
✅ Water-Based Formula – Unlike solvent-based fire retardants, Rosco Flamex products are low in volatile organic compounds (VOCs), reducing inhalation risks.
✅ Meets NFPA 701 Standards – Ensures compliance with fire safety regulations.
✅ Designed for Various Materials – Different formulations exist for fabrics, wood, paper, and synthetic materials.
✅ Minimal Odor and Residue – Helps maintain the quality of treated materials without affecting aesthetics.
Potential Risks:
❌ Skin or Eye Irritation – As with any chemical, prolonged exposure to wet surfaces can cause irritation. Gloves and eye protection are recommended when applying.
❌ Inhalation Risk (During Application) – Spraying in an enclosed area without proper ventilation may lead to minor respiratory discomfort. Always apply in a well-ventilated space.
Safety Data: According to Rosco’s Safety Data Sheet (SDS), Flamex products are classified as non-hazardous under normal use but should not be ingested or applied to skin directly (Rosco, 2023).
3. Examining Turning Star Fire Retardants
Turning Star specializes in eco-friendly and non-toxic fire retardant solutions, often used in theatres, museums, and commercial venues. Their formulations prioritize both fire safety and environmental responsibility.
Key Safety Features of Turning Star Fire Retardants:
✅ Non-Toxic & Biodegradable – Free from halogens, PBDEs, and heavy metals, making them safer for people and the environment.
✅ No Harmful Fumes – Unlike older chemical treatments, Turning Star’s water-based formulas are safe for indoor application.
✅ Long-Lasting & Non-Corrosive – Protects materials without causing deterioration.
✅ Safe for Performers and Crew – Designed for minimal health risks when properly applied.
Potential Risks:
❌ May Wash Out Over Time – Water-based fire retardants may require reapplication after extended use or exposure to moisture.
❌ Application Safety – Though non-toxic, wearing gloves and using proper ventilation is still recommended when applying.
Safety Data: Turning Star’s SDS reports confirm that their fire retardants are free from hazardous air pollutants (HAPs) and do not release toxic fumes (Turning Star, 2023).
4. Fire Code Compliance & Safety Precautions
When using fire retardants in a professional theatre setting, it is essential to follow these safety measures:
✔ Use Certified Fire Retardants – Ensure the product meets NFPA 701, ASTM E84, or local fire codes.
✔ Apply in a Ventilated Area – Although modern formulas are low-VOC, proper airflow minimizes any inhalation risks.
✔ Wear Protective Gear – Gloves and goggles are recommended during application.
✔ Perform Regular Inspections – Over time, flame-retardant treatments may wear off due to cleaning or humidity, requiring retesting and reapplication.
✔ Consult Manufacturer SDS Sheets – Always review Safety Data Sheets to understand proper handling and disposal.
Final Verdict: Are Fire Retardants Toxic?
✅ Modern fire retardants like Rosco Flamex and Turning Star are designed to be non-toxic and safe for theatre applications when used properly.
✅ Older or industrial-grade fire retardants may pose health risks, but modern water-based formulations reduce these hazards significantly.
✅ Proper application, ventilation, and safety precautions are key to minimizing any exposure risks.
For theatre professionals, selecting high-quality, tested, and compliant fire retardants ensures both fire safety and performer well-being. By choosing products that meet regulatory standards and applying them correctly, you can maintain a safe and compliant stage environment without unnecessary health risks.
