Safety, Ethics, and Professional Practice
Safety
Concrete drilling for F2170 generates silica dust; use dust extraction, wet methods where appropriate, and respiratory protection. Follow SDS requirements for sealants, adhesives, and cleaners. Control electrical cords, keep walkways clear, and use fall protection where required. Calibrate and inspect instruments before use. Plan for confined spaces and hot-work permits when applicable.
Ethics and professional practice
Report what the standard method actually produced. Do not alter, omit, or selectively average results to satisfy a contractor or schedule. Disclose deviations, calibration status, and limitations. Work only within your competence and training; if a method is outside your scope, say so. Avoid conflicts of interest and keep client information confidential.
Worked example
A contractor asks a technician to delete a 91% RH reading because the average passes. The ethical response is to keep the reading, explain that acceptance is based on the specified limit and controlling location, and document the request and the refusal. Altering the record would misrepresent the slab and could cause a floor failure.
Traps
Falsifying data, testing outside the standard, hiding a deviation, or accepting a job beyond your competence are professional failures. Safety shortcuts around silica dust and electrical hazards are equally costly.
