proaching traffic signal and never "see" it. The field of vi‐ sion of what you do see also narrows significantly. There is some good news. It appears that listening to music while driving has little if any negative effect. Con‐ versing with a passenger seems (in some studies) to be less distracting. It is thought that when the passenger is present and aware of driving conditions (not miles away in an office), the passenger and driver can somehow miti‐ gate the cognitive distraction. Certainly there are relevant applications in the workplace. Distracting those operating equipment, performing me‐ chanical work or electrical work, come to mind. As we search for new approaches to reduce risk in the work‐ place, this research may prove useful. However, it may just be that the greatest impact to safety would be the active avoidance of distractions by each em‐ ployee when driving to work and back home again each day. Noise Dosimeter is World's Smallest Casella CEL, offers the CEL‐350 dBadge micro noise dosimeter. Amaz‐ ingly compact, this breakthrough safety tool is designed to measure the noise exposure of an employee over the working day to uncover danger‐ ous areas and to assure compliance with strict OSHA, NIOSH or ISO (Euro‐ pean) regulations. Many industrial professionals have tried personal dose badges and found they compromise performance for a smaller size. Casella CEL has an‐ swered these limitations by engineer‐ ing the new CEL‐350 dBadge with the features that the others lack, such as a built‐in display, a cable‐free architec‐ ture, simultaneous measurement of both OSHA and ISO parameters, and faster battery recharging, all con‐ tained within a small, unobtrusive housing that weighs just 2 oz. Unlike with conventional sound expo‐ sure meters, an employee can com‐ fortably wear the CEL‐350 dBadge all day by attaching it to a shirt, overalls or hardhat. There are no microphone cables to damage or get caught up in, nor is other external equipment re‐ quired. In fact, the instrument is oper‐ ated with only two buttons located on its side. Auto‐calibration is performed with any standard acoustic calibrator – no other setup is needed. Once in operation, the unit captures a www.rockproducts.com time history for every noise event, in‐ cluding average noise level and peak value, which is logged in one‐minute values for later analysis. Its 64 KB memory stores up to 180 hours of data. Another key to the success of the dBadge is its built‐in display, a first for dosimeters its size. The display makes it easy to perform calibration, while also providing status informa‐ tion and key measured data. In addi‐ tion, there is an ultra‐bright LED that gives a visual indication of when ex‐ posure action levels have been ex‐ ceeded by flashing at different rates. Industrial hygienists or safety officers looking to perform analysis of work‐ place noise begin by downloading the measurements stored in the CEL‐350 dBadge into a PC. Report templates supplied with the dB35 database soft‐ ware supplied with the unit allow for generation of user‐defined databases. Data is viewed according to ISO and OSHA measurement protocols, or in displays customized to a specific user's own requirements. For larger organizations, data can be shared with colleagues anywhere in the world using the software's import and ex‐ port feature. It can also be imported into different programs for reporting. The CEL‐350 dBadge is a robust in‐ strument engineered to withstand the wear and tear associated with indus‐ trial environments. It is manufactured using the same material as is used in many automobile bumpers. Also, since the controls can be locked, the risk of tampering or misuse is considerably reduced. Along with the standard CEL‐350 dBadge, Casella CEL offers an Intrinsi‐ cally Safe version for hazardous loca‐ tions such as mines, petrochemical plants and paint factories. The unit's built‐in NiMH rechargeable battery pack will run for up to 32 hours, giving four 8‐hour shifts under normal conditions. Recharging takes only 90 minutes.
