3.23 Health Hazard. Refers to chemicals for which there are statistically significant evidence based on at least one study conducted in accordance with established scientific principles that acute or chronic health effects may occur in exposed employees. Exposure may result in adverse effects to the worker, public or environment, or meeting the characteristics of a health or physical hazard criteria as presented in 29 CFR 1910.1200, Appendices A and B. A condition in which an employee’s exposure to a chemical sub-stance, biological agent or physical agent is in excess of those permitted levels established by the regulatory agencies having jurisdiction, or in excess of guidelines established by consensus standards organizations, or any other generally recognized hazard that affects employee health (e.g., poor sanitation).
3.24 Intrinsic Hazardous Materials. Hazardous materials that make up or are included within building materials and/or equipment by design as opposed to contamination. Examples are asbestos, lead paint and polychlorinated biphenyls (PCB5).
3.25 Laboratory. An individual room or suite of rooms within a facility equipped for research in a science or for testing and analysis. It contains appropriate engineering control features and equipment required to protect personnel working in the laboratory, the environment and personnel outside of the laboratory from potential hazards. These hazards may include but are not limited to animals, biological agents and their toxins, chemicals, electromagnetic fields, electricity, lasers, machinery, ionizing and non-ionizing radiation and robotics.
3.26 Mitigation. The process of correcting known risks and reducing future risks.
3.28 Occupational Exposure Limit (OEL).
A concentration of contaminant in air not to
be exceeded in the breathing zone of
employees.
3.29 Occupational Health and Safety Professional (OH&S). Someone who by training or experience is qualified to work in the field of occupational health and safety. Specific credentials as examples of someone who may be deemed a professional will include, in part, CIH, CSP, CHMM, RBP, SM (NRCM) and/or CBSP as defined in Appendix J.
3.30 Permissible Exposure Limit (PEL). The permissible exposure limit is a legal limit in the United States for exposure of an employee to a chemical substance or physical agent. For chemicals, the chemical regulation is usually expressed in parts per million (ppm), or sometimes in milligrams per cubic meter (mg/rn3). A PEL is usually given as a time-weighted average (TWA), although some are short-term exposure limits (STEL).
3.31 Process Contamination. A facility (and equipment) that has been contaminated by the processes conducted therein. This includes radioactive, chemical, explosive and/or biological contamination. This term is limited to materials and quantities declared to be hazardous by federal or state regulations or other applicable standards. It does not include materials used in the construction of the facility or background constituents that are indigenous.
3.32 Qualified Person. Someone who by possession of a recognized academic degree, certificate or professional standing, or who by appropriate knowledge, training and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter, the work or the project.
