- OHSAS 18001 is an Occupation Health and Safety Assessment Series for health and safety management systems. It is intended to help an organizations to control occupational health and safety risks. It was devloped in response to widespread demand for a recognized standard against which to be certified and assessed.
- Time-Weighted-Average is NIOSH 8 hour exposure limit. STEL is the short term exposure limit.

- *http://staff.washington.edu/rneitzel/NIPTS_final_report.pdf REMEMBER! Noise is measured and recorded as decibels on the A weighted scale and the OSHA Permissible Exposure Limit is 90 decibels (dB) that is an eight hour time weighted average: aka, 90dBA TWA There is no action level , below 90 dBA, established in the construction standard However , in 1992 OSHA issued a letter of interpretation that outlines what a hearing conservation program in construction should be.
- Source : 6/29/1992 Interpretation letter from Pat Clark, OSHA Director of Compliance Programs, to FW Lundy, Corporate Safety Director, BE&K Construction Company, Birmingham Alabama (1) Monitoring of employee noise exposures, (2) The instigation of engineering, work practice, and administrative controls for excessive noise, (3) The provision of each overexposed employee with an individually fitted hearing protector with an adequate noise reduction rating, (4) Employee training and education regarding noise hazards and protection measures,

- Chromium hexavalent (CrVI) compounds, often called hexavalent chromium, exist in several forms. Industrial uses of hexavalent chromium compounds include chromate pigments in dyes, paints, inks, and plastics; chromates added as anticorrosive agents to paints, primers, and other surface coatings; and chromic acid electroplated onto metal parts to provide a decorative or protective coating. Hexavalent chromium can also be formed when performing "hot work" such as welding on stainless steel or melting chromium metal. In these situations the chromium is not originally hexavalent, but the high temperatures involved in the process result in oxidation that converts the chromium to a hexavalent state. Exposures to hexavalent chromium (Cr(VI)) are addressed in specific standards for the general industry, rules concerning OSHA access to employee medical reports, shipyard employment, marine terminals, and the construction industry.
- blue smoke (mainly oil and unburnt fuel) which indicates a poorly serviced and/or tuned engine; black smoke (soot, oil and unburnt fuel) which indicates a mechanical fault with the engine; white smoke (water droplets and unburnt fuel) which is produced when the engine is started from cold and disappears when the engine warms up.
- CO TWA is _50__ ppm. Name one place where cadmium can be found on construction. ___Bolts, sprinklers, metal poles, rust coating___________ _20.9 __% Oxygen is normal air. Which color smoke from a diesel engine is a concern? __ALL or blue________________ Overexposure less than _15___ minutes when torch cutting lead painted surfaces The Short Term Exposure Limit (STEL) is for 15____ minutes
