Hazardous Materials Assessments

Occupational Health and Safety legislation states that the employer is responsible for identifying hazardous materials such as asbestos, mould, lead, PCB’s, mercury, and radioactive materials prior to any renovation or abatement project. Impacting these materials may expose occupants or workers to these hazards if proper safety measures have not been put in place to safely control exposure. A professional assessment will identify which hazardous materials, if any, exist, where they are located, and recommendations for controlling exposure. An ASE Services Hazardous Materials Assessment Report will also provide conclusions about the potential for exposure, as well as recommendations for next steps. This detailed report contains floor plans and photographs to visually describe the location and condition of any hazardous materials.

If you decide to have the hazardous materials remediated, ASE Services can assist you with any, or all, of the following tasks to ensure the successful completion of your project:

  • Developing a proper Scope of Work that outlines the requirements and restrictions of the remediation project
  • Creating a tender package for contractors to bid to work on the project
  • Assisting with hiring a qualified contractor to abate or remove the materials
  • Conducting air monitoring and inspections during the project to ensure compliance with the legislation
  • Provide final inspections and a clearance report once abatement is completed. It is important to ensure the area is safe for re-occupancy or demolition

Asbestos

Asbestos is a group of naturally occurring mineral (rock) fibres found all over the world.  Throughout the 20th century, it was often combined with building related materials due to its fire retardant and insulation properties. Asbestos has since been labelled a hazardous material and it’s use is highly restricted. Inhaling asbestos fibres can cause detrimental health effects and can lead to life threatening illness like mesothelioma and asbestosis.

Asbestos fibre may be located in several areas of a home or building, such as:

  • Walls
  • Ceilings
  • Floors
  • Window caulking
  • Mechanical insulating products
  • Electrical products
  • Roofing materials
  • Exterior brick or siding

Please feel free to contact ASE Services if you have any questions or concerns about asbestos in your home or workplace.

It is always a good idea to hire a professional company, such as ASE Services, to perform an asbestos assessment of your home or building prior to beginning a maintenance, renovation, or demolition project – especially if it was built prior to the 1990’s. An assessment will determine which areas contain asbestos, as well as the amount and type of asbestos within the building material. Once an assessment has been completed, ASE Services can assist you with a plan to properly, and safely, address and remediate the hazardous material.

Mould

An indoor environment has everything mould spores need to grow -- the right temperature and a food source such as drywall, plywood, etc.  It only needs moisture or a water source. Mould will grow if a moisture source is introduced into the environment. Water intrusions from an outdoor source, like flooding or roof and window leaks, or an indoor source, like broken plumbing lines, need to be properly repaired and the area cleaned and dried within 48 hrs or mould growth can occur. Mould will continue to grow, or re-emerge, as long as the moisture source remains. Any material damage or health concerns will also continue to occur.

Symptoms of mould exposure include:

  • Skin irritations or rashes
  • Dry hacking cough
  • Nose, eye or throat irritations
  • Nasal or sinus congestion
  • Wheezing or difficulty breathing

People who spend extended periods of time in an indoor setting with mould will likely experience irritant or allergic responses. The more an individual is exposed to mould, the higher the health risks.  Some people may be more sensitive to mould exposure and may experience more severe reactions.  Always consult a physician if you have any lingering or concerning symptoms..

If you feel that there is a mould issue in your home or building, you should bring in a professional company to conduct a mould assessment. This may include a visual inspection, moisture measurements, and air sampling.  Once the mould source has been identified, and the area properly cleaned or remediated, the health symptoms associated with exposure should subside. Please do not hesitate to consult a doctor if your health issues continue or worsen.

Consult the professionals at ASE Services to assist you in answering your questions or to perform an assessment if you suspect that you have a mould issue.
