Deleterious Materials

All materials have the potential to be harmful under certain conditions. But what exactly are deleterious materials, where might they be found, and how can we assist you in managing them effectively?

Understanding Deleterious Materials

Deleterious materials are substances or construction practices that pose health, safety, or environmental risks, or are prone to failure over time. While certain materials may be suitable in specific applications, their improper use can lead to serious issues, including structural failure, legal breaches, or health hazards.

Early detection, through thorough visual inspections and material sampling, is critical to managing these risks. Comprehensive risk assessments, control measures, and safe working practices are required by law to mitigate potential hazards. Non-compliance can result in legal penalties, operational delays, and reputational damage.

How We Support Your Business

At Summit Environmental, we specialise in identifying, assessing, and managing prohibited and hazardous materials in construction. Our consultancy services ensure compliance with construction contracts, reduce risk exposure, and support sustainable, safe, and legally sound project delivery.

Common Deleterious Materials

  • Asbestos: Asbestos, a well-documented hazardous material and a Class 1 carcinogen, requires stringent risk management to ensure compliance and protect health.
  • Vermiculite: Although vermiculite is generally safe, older insulation products containing this material may harbour asbestos fibres, which can pose inhalation risks.
  • Silica Dust: A significant hazard in the construction industry, silica dust is generated during tasks such as cutting, drilling, and grinding. Prolonged exposure may lead to silicosis or lung cancer.
  • Greenhouse Gases (CFCs, HCFCs): These gases, commonly used in insulation materials and refrigeration systems, are significant contributors to climate change if not properly managed.
  • Volatile Organic Compounds (VOCs): Found in paints, adhesives, and cleaning agents, VOCs release harmful emissions that impact indoor air quality and worker safety.
  • Refractory Ceramic Fibres (RCFs) and Man-Made Mineral Fibres (MMMFs): RCFs and MMMFs are used extensively in insulation and industrial applications. Exposure can lead to respiratory irritation and long-term health risks.
  • Lead: Lead is present in older paint, piping, and flashing materials. Inhalation or ingestion can result in severe health issues. Lead surveys and testing are particularly critical in heritage or refurbishment projects.
  • Polychlorinated Biphenyls (PCBs): Previously used in electrical equipment, PCBs are toxic chemicals associated with health issues, including skin conditions and systemic effects.
  • Mercury: A highly toxic material, mercury can enter the body through vapour inhalation. It is commonly found in older industrial and construction applications.
  • Hair Plaster: Historically used plaster reinforced with animal hair may carry Bacillus anthracis, the bacteria responsible for anthrax. This material requires specialist analysis and management.
  • Polyurethane Foam: Polyurethane foam, used in insulation and prefabricated panels, may release harmful compounds when damaged or improperly handled.
  • Urea Formaldehyde: Widely used in adhesives and insulation, urea formaldehyde can emit formaldehyde gas, posing risks to respiratory health and long-term safety.
