Anthrax Horse Hair Plaster Surveys & Testing in Bath, Bristol, Somerset

Anthrax Surveys and Testing of Animal Hair in Plaster: Bath & Bristol, Somerset

Comprehensive Surveys for Historical Plasters

Specializing in historical properties across Bath and Bristol, Somerset our team conducts thorough anthrax surveys and tests on animal hair—including horsehair—found in traditional lath and plaster or other heritage plaster types within older buildings.

Understanding Anthrax in Traditional Materials

Anthrax is a resilient bacterium that exists as spores and is found in livestock-derived materials such as horse, cow, ox, and goat hair and hides. These spores can survive in varied conditions, not only within textile industries but also within the plaster materials commonly used in historical buildings in Bath, Bristol, Somerset and surrounding areas.

Horsehair and other animal-derived hairs have been integral to traditional plaster applications for centuries. Initial regulations, such as the 1919 Act for UK animal hair and the 1921 Order for imported animal products, aimed to address anthrax risks but lacked effectiveness and enforcement as they were not mandatory. Mandatory sterilization protocols were only gradually introduced, with 1935 bringing more robust disinfection controls. Even so, these measures were less stringent than the comprehensive Anthrax Prevention Order of 1971, which implemented modernized safety measures. Consequently, the risk of anthrax in plaster isn’t confined to pre-1921 constructions but remains a consideration for all period properties.

Key Considerations for Property Works

Refurbishment, demolition, or maintenance work on properties in Bath and Bristol may necessitate anthrax sampling or full surveys to assess the risk associated with traditional plaster. Relevant legislation, including the Control of Substances Hazardous to Health (COSHH) Regulations 2002 and the Construction (Design and Management) (CDM) Regulations 2007, imposes legal duties to minimize health risks.

The Anthrax Survey Process

The methodology for an anthrax survey mirrors that of other hazardous material assessments. Surveyors perform an on-site inspection to visually identify period plaster finishes containing hair, commonly found in ceiling and wall applications. Horsehair plaster is typically applied to wooden laths or directly to solid substrates like brick, stone, or render, other materials such including roof felts such as sarking felt. The type of animal hair present is less critical than the mere presence of hair, as anthrax risk is associated with animal hairs in general.

Sampling and Laboratory Testing

Following the site inspection, plaster samples are collected following strict guidelines regarding sample size and coverage to ensure meaningful and reliable results. Single samples from multi-room or multi-floor buildings are insufficient; adequate sampling is essential for a dependable assessment. Collected samples are then incubated and cultured over a 10-day period to determine anthrax presence.

Properties at Greater Risk

Historical properties in Bath and Bristol, including period residential buildings and mixed-use commercial structures featuring lath and plaster or plaster on solid substrates, are prime candidates for anthrax testing. Situations like planned renovations, fire damage, or water escape heighten the necessity for these evaluations.

Comprehensive Reporting

Upon completing laboratory analysis, we compile detailed reports that include:

• Anthrax Plaster Register detailing identified applications.
• Floor Plans and Sampling Locations for transparency.
• Laboratory Certificates confirming the results of tested samples.
• Risk Mitigation Recommendations tailored to the specific property and planned works.

Single-Point Testing for Localized Concerns

For minor projects or isolated areas, such as damage to a single wall or ceiling, we offer single-spot anthrax testing as an alternative to a full survey. This approach is particularly beneficial in cases of accidental damage or water ingress, providing localized results quickly and efficiently.
