Workplace Environment

Hazardous Materials

(Asbestos, Lead, PCB’s etc.) – the SDI Group can provide complete services for the development and implementation of strategies relating to hazardous materials, including Hazardous Materials Assessments (Asbestos, Lead, PCB, Mercury – sampling and quantification), Hazardous Materials Management Plans and Hazardous Material Removal Management (i.e. asbestos air monitoring and assessments).

Indoor Air Quality (IAQ)

The SDI Group offers a complete range of IAQ services, from initial assessments to complete evaluation programs – or emergency response to any situation. We can develop practical, cost effective solutions for your IAQ problems, including MSDS Review (WHMIS), general IAQ parameter monitoring (carbon dioxide, carbon monoxide, temperature, relative humidity and airborne mould), work site assessment and review of site processes and work procedures.

Mould Assessments

The SDI Group offers complete services in the area of mould assessment, using both non-intrusive and intrusive investigative techniques in a variety of settings, including residential, office, and industrial settings. On top of our assessments, the SDI Team can provide abatement specifications and tender documents, abatement supervision and inspection, and final clearance inspections and testing, as required.

Chemical Storage & Inventories

The SDI Group’s expert staff provides complete on-site chemical inventory services. We have the experienced personnel to ensure an accurate account of your chemical inventory and ensure all chemicals are stored properly.

The major quantity of most chemicals should be stored in acid cabinets, flammables cabinets, or in appropriate storage areas.
The SDI Group has built many different chemical management systems to help provide efficient inventory capture and integration into your current business operations.

Noise Monitoring

The SDI Group has carried out assessments of exposure to noise within the workplace to help you comply with the Alberta Occupational Health and Safety Act, Regulation and Code.

These assessments and surveys are required for a huge range of workplace activities from manufacturing, construction, and even schools and office environments. Often only small areas of these organizations may pose a risk to health and the set up of simple safeguards and working practices can resolve any potential problems caused by elevated noise levels. For example, you may have areas of your business that you have difficulty communicating in. If you find yourself having to shout to make yourself heard, it is very probable that you have a problem and action may be required to ensure an employee’s hearing is not damaged.

Noise Zone Identification is carried out by plotting noise levels onto site plans so that noise contours can be plotted; this permit “hearing protection zones” to be set up to enable managers to appreciate where concerns exist and for staff to know where protection should be worn.

Dosimetry is carried out for monitoring work shift exposure to determine the time weighted average exposure by using a personal monitor worn by a worker. This data can be compared with the OHS code to determine compliance with the exposure levels in a workplace.

These types of noise monitoring will determine the most suitable control method to reduce exposure of noise, should it be required, and enable you to select the most suitable ear protection for your workplace, when found necessary. A report will be issued detailing all findings from the noise monitoring/risk assessment along with necessary workplace changes that must be made, and recommendations of what hearing protection is required.

The SDI Group has also helped to build hearing conservation programs which have included, but are not limited to: yearly noise measurements, education and training, hearing protection selection, engineered and administrative noise control, posting of noise hazard areas, audiometric (hearing) testing and annual program review.

Occupational Exposure Monitoring

Many people are exposed to a variety of hazardous substances at work that can, under certain circumstances, have a harmful effect on their health. A hazardous substance can occur in many forms; for example: solids, liquids, vapours, gases, dust, fibres, fumes, mist and smoke.

The SDI Group is available to undertake a wide range of personal monitoring campaigns, for all types of hazardous substances, in accordance with the latest monitoring methods and techniques.

The SDI Group has carried out occupational exposure monitoring for firms for various chemical hazards including:

  • paints
  • resins
  • polymers
  • isocyanates
  • welding fume
  • silica

Our overall objective is to assist firms in complying with Safety, Health, and Environmental legislation, while maintaining or improving process efficiency. We recognize that our clients need us to find solutions, rather than just define problems, and we are fortunate in being able to call upon the extensive experience within our organization.

Upon completion of the exposure monitoring, a full interpretive report will be provided where all analysis results will be related to current occupational exposure limits, with recommendations and advice provided on how to reduce employee exposure where necessary.
