Building construction has developed throughout mans history from rudimentary construction with natural materials to more complex construction techniques with revolutionary materials to make the building safe and reduce the spread of fire. Asbestos has been used since ancient times in various textile applications and some was used as insulation during the period 1870-1900, but its use became more common on steam pipes and boilers in ships after 1900. The use of asbestos started expanding to include acoustical and decorative purposes, and spray applied asbestos fireproofing especially in buildings. Asbestos use in the United States started to decline in the period from 1973 to 1978 when EPA bans on spray-applied asbestos materials were established.
In response to the growing concern on asbestos-related health risks, the Ontario Ministry of Labour issued Ontario Regulation (O.R.) 838/90 under the Occupational Health & Safety Act.
Provincial regulations vary, but most require surveys for daily management of asbestos materials even in the absence of construction work. All provinces require surveys prior to renovations that may disturb asbestos materials.
Envirocure assists building owners, industrial managers, government agencies, developers and contractors to identify asbestos materials in their buildings and facilities. These surveys may be used to develop management plans to protect the health of the public, staff and employees.
