N. Industrial Hygiene: An area of specialization in the field of industrial safety and health that is concerned with predicting, recognizing, assessing, controlling, and preventing environmental stressors in the workplace that can lead to sickness, disease, or other forms of impaired health.

O. Industrial Hygienist: A person having a college or university degree(s) in engineering, chemistry, physics, medicine, or related physical or biological sciences who, by virtue of special studies and training, has acquired competence in industrial hygiene.

P. Intact: ACM that has not crumbled, been pulverized, or otherwise deteriorated so that the asbestos is no longer likely to be bound with its matrix.

Q. Negative Initial Exposure Assessment: An assessment by an industrial hygienist which demonstrates that employee exposure during an operation is expected to be consistently below the permissible exposure limit (PEL) for representative 8-hour time-weighted average (TWA) samples and 30-minute excursion limit (EL) samples.

U. Regulated Work Area: An area established by the abatement contractor to demarcate areas where Class I, II, and III asbestos work is conducted, and any adjoining area where debris and waste from such asbestos work accumulate, and a Regulated Work Area within which airborne concentrations of asbestos, exceed or there is a reasonable possibility they may exceed, the permissible exposure limit.

V. Removal: All operations where ACM and/or PACM are removed or stripped from structures or substrates, includes demolition operations.

W. Renovation: Modifying of any existing structure, or portion thereof.

X. Surfactant: A chemical wetting agent added to water to improve wetting and penetration into a substrate.
