The 1950s to the 1970s marked the zenith of asbestos usage in New Zealand. During this era, asbestos was omnipresent in various industries, including construction, shipbuilding, and manufacturing. Notably, many residential and commercial structures built during this period contained asbestos in numerous forms:
- Construction: Asbestos continued to be used in roofing materials, tiles, and siding due to its fire-resistant properties. The construction industry relied heavily on asbestos-containing materials.
- Shipbuilding: Asbestos was extensively used in shipbuilding, primarily for insulation and fireproofing purposes. This exposed workers in the maritime industry to significant asbestos-related risks.
- Home Construction: Homes constructed during the 1950s-1970s often incorporated asbestos in insulation, piping, and even as a component of wall materials. This posed potential health risks to residents over time.
- Textured Ceilings: Textured ceilings, which gained popularity in the mid-20th century, continued to contain asbestos. These ceilings were used in homes and commercial buildings.
Late 20th Century: Growing Awareness and Initial Regulations
The late 20th century witnessed a significant shift in New Zealand’s approach to asbestos, driven by growing global awareness of the severe health risks associated with asbestos exposure, including diseases like asbestosis, lung cancer, and mesothelioma. During this period, New Zealand started to acknowledge the international discourse surrounding asbestos and took steps to address the dangers it posed to public health and worker safety.
Late 1970s: Global Recognition of Asbestos Health Risks
In the late 1970s, the world began to wake up to the alarming health effects linked to asbestos exposure. New Zealand was no exception, as concerns about the adverse health outcomes of asbestos-related diseases, such as asbestosis and various types of cancer, gained prominence on a global scale. These diseases were often associated with long-term exposure to asbestos fibers, which could be inhaled or ingested during activities involving asbestos-containing materials.
1984: Asbestos Regulations 1984
In response to the growing awareness of asbestos-related health risks, New Zealand took a significant step in 1984 by implementing the Asbestos Regulations 1984. These regulations laid down crucial guidelines and requirements for the handling, removal, and importation of asbestos-containing materials. Some key aspects of these regulations included:
- Safe Handling: Guidelines for the safe handling of asbestos materials were established, emphasizing the importance of minimizing the release of asbestos fibers into the environment during construction, renovation, and demolition activities.
- Removal Procedures: The regulations outlined specific procedures for the safe removal of asbestos-containing materials, particularly in occupational settings. These procedures aimed to protect workers from hazardous asbestos exposure.
- Importation Control: Stricter controls were imposed on the importation of asbestos-containing products and materials, reducing the influx of potentially hazardous asbestos materials into the country.
1990s: Strengthening Regulations and Public Awareness
Throughout the 1990s, New Zealand continued to strengthen its regulatory framework to mitigate asbestos-related risks and protect both workers and the public. Key developments during this decade included:
- Asbestos Removal Licensing: The introduction of requirements for asbestos removal licenses ensured that only qualified and certified individuals or companies could undertake asbestos removal projects, thereby enhancing safety measures during asbestos abatement.
- Workplace Safety Standards: More stringent workplace safety standards were established, mandating the use of protective equipment, containment measures, and proper disposal practices when working with asbestos-containing materials.
- Awareness Campaigns: Public awareness campaigns were launched to educate the general public and industries about the risks associated with asbestos exposure. These campaigns aimed to promote responsible handling and reporting of asbestos-containing materials.
21st Century: Tightened Regulations and Asbestos Ban
